Windows: Repair or Replace?


There’s a host of elements to think about when updating your home’s windows– specifically if you are living in a period home.


Your home’s windows are an essential part of its character. They work along with the external cladding and roofing products to form part of an architectural photo that sets the tone for the rest of the home. So if you’re taking on a renovation project and your fenestration requires attention, choosing exactly how to proceed is not something to be taken lightly.

In most situations, repairing and changing windows like-for-like is thought about permitted development (PD). This indicates you don’t usually have to get specific preparing approval, unless your project involves considerable changes.

Some councils are more versatile about this than others, so inspect what’s required. You might be expected to precisely match the style, products and method of opening of the originals before going ahead.

Note that bay windows are likely to be classed as extensions that require formal approval.

Repair work are typically also permissible in noted buildings– however replacement tends to be a little more strictly managed are needs noted structure consent. Modifications to the design or the insertion of double glazing in such properties will likewise need specific consent.

Fixing existing windows
If you’re handling a significant project that includes tired-looking windows, it can be easy to hurry into the idea of switching them out for brand-new products. This isn’t the only alternative, as damaged systems can typically be brought back into service by a skilled joiner or expert business.

Certainly, you may find that it makes more sense to refurbish what you’ve already got. This is especially real if you live in a period residential or commercial property, where preserving original examples could be key to preserving the house’s character and worth.

Even systems that seem decaying (telltale signs consist of flaking paint, sticking sashes and spongy wood that can be easily removed with a screwdriver) can be successfully reconditioned. Cills and lower rails are well-known weak points however are relatively easy to resolve. Depending on the level of the work, it might prove cheaper to repair rather than replace.

The precise procedure will depend on the problem at hand and underlying condition of the frame. Normally, any decaying timbers can be cut or routed back to sound wood and brand-new sections (moulded to match the originals) scarfed into the frame. These are then sealed and primed, prepared for design.

Developments in glazing enabled the Victorians to fit big one-over-one sash windows that maximise views and light.

Repairing draughty windows
Another typical problem that can develop over time is draughts. This is the most typical reason for substantial heat loss through old windows (much more so than through single glazing). Sometimes cracks and spaces might be plainly noticeable; in others there may be indications of mould or condensation that direct you towards the problem location.

There are 2 primary routes to upgrading. You might insert suitable draught proofing strips (most firms will do this as a matter of course while fixing windows). You could fit secondary glazing behind the system, on the internal side.

Both procedures will likewise help to lower noise issues and dust ingress. They represent the least intrusive methods to enhance comfort levels while protecting a home’s look.

Is it worth repairing standard windows?
Typically, substantial repair is just truly rewarding on heritage systems. There’s seldom much point in trying to restore a rotting 1980s softwood window, for example, as couple of items from this period are likely to be of a high sufficient quality to benefit refurbishment.

It could still prove cost-efficient to replace panes that are misting up with condensation (usually a result of harmed seals) rather than removing out the entire unit.

Worn away metal windows can likewise be brought back into good condition through professional processes, such as acid pickling or flame cleaning (note that rust expands, so it often looks worse than it truly is). Steel units struggling with bowing or similar concerns can in some cases be fixed with brand-new welded-in areas if required.

Changing windows
It isn’t always cost-effective to repair old systems; in some cases getting rid of them and starting once again is the only viable course. With duration properties, this is especially true if originals have actually previously been swapped out for low-cost, improper variations. This was regrettably a commonplace practice in the late 20th century.

In such cases, reinstating preferable fenestration might in fact add worth. It’s also a pretty safe bet if you have actually a property constructed post-1960 where the windows are no longer using great service (unless it’s a particularly amazing building that benefits a conservation method).

Like-for-like replacement will always be the path of least resistance from a preparation point of view. Depending upon your task, however, you may have the ability to gain consent for a different material or perhaps a more uncommon design (more on this later).

Note that all replacement windows come under the scope of the Building Regulations (whereas repair work are exempt from the guidelines).

The main thrust of the regs is to guarantee good thermal performance (through Part L1B) and minimum security standards (Part Q). When it comes to efficiency, the headline figures are that systems ought to achieve a minimum Window Energy Rating (WER) of Band C, or hit a threshold U-value (a procedure of heat loss) of 1.6 W/m2K.

Properly-installed factory-made double glazed items will constantly carry out to the necessary requirement. If you need a one-off bespoke system, any specialist company or joiner worth their salt need to understand the ins-and-outs of how to accomplish your performance requirements.

Materials options for replacement windows
One huge question when changing windows is the traditional argument of which frame product to choose. The leading competitors are wood, PVCu and metal– and each has its benefits when it concerns restoration projects.

Wood windows
Timber is a natural option for lots of plans, specifically where conservation issues are included or you have the budget plan to switch like-with-like. Few materials can match the natural appeal or toughness of wood– whether painted or stained, softwood or hardwood.

Modern factory-painted variations tend to come with assurances of at least 10 years on the finish. Provided they’re kept appropriately they should last in excess of 60 years prior to replacement is needed. Timber can be used to attain a range of designs and surfaces, with the flexibility to deliver the thin glazing bars that tend to match duration properties.

Wood is also a natural insulator, so usually uses a somewhat enhanced whole-unit U-value compared to other products. It doesn’t come cheap, however: expect to pay at least ₤ 200 per m2 for untreated softwood systems. Pre-painted wood windows begin with around ₤ 300 per m2, whilst wood variations can cost substantially more.

PVCu windows
PVCu windows are always going to be a strong contender for budget-conscious renovators (rates start from around ₤ 150 per m2).

Design-wise, these advances also suggest plastic frames can be a much better fit in period homes than they were a decade earlier. This is mostly due to the fact that profiles are getting thinner. That said, they still can’t quite match timber and aluminium.

Metal windows
Metal items are likewise exceptionally low-maintenance, with alternatives including galvanised steel, bronze and powder-coated aluminium. They provide the slimmest sightlines of all, which can look wonderful in both standard and modern settings. This will also maximise the amount of natural light that filters into your house’s interiors.

You’ll pay for the privilege (rates begin with around ₤ 300 per m2), but you’ll get the benefit of a high-quality item with a service life of a minimum of 45 years.

You can likewise purchase composite windows that integrate timber with aluminium cladding. This offers the best of both worlds: heat internally and a low-maintenance external surface.

Changing configurations
If you’re replacing windows anyhow, you might wish to reassess the kind and function of your fenestration. PD rights can enable you to change, enlarge and place brand-new systems in an existing structure– offered they look similar to those in the main house.

Check with your local council how far you can go, and whether a formal planning application might be needed. This is most likely to be required if you prepare to alter the design considerably. Remember you will require different authorisation for this kind of task if you’re dealing with a noted residential or commercial property.

Changes such as including floor-to-ceiling glazing at the rear of an existing home might change the way you connect with your living space. Key objectives consist of allowing more natural light to flood the interiors and creating a better connection with the garden.

If you’re starting a duration renovation, keep in mind significant intervention can affect the fabric of the structure. Take on the works carefully to make sure heritage surfaces are maintained.

A note on ventilation
Historical buildings were built as ‘breathable’ entities, allowing wetness to wick through the structural fabric and, ultimately, evaporate. Good ventilation is important to preserving this scenario.

Draught proofing or switching to sealed modern systems can cut out a possible source of air infiltration. However, in isolation, updating windows is extremely not likely to prevent the structure breathing effectively.

Provided you take basic preventative measures– such as avoiding modern impermeable paints and making sure suitable natural or artificial sources of ventilation exist in kitchens, bathrooms and comparable zones– there should be no concerns.

What Will Triple Glazed Sash Windows Do For Noise Reduction

The general consensus is that roadways are getting noisier/busier gradually and flight path noise becoming a growing number of excruciating.

Seeking to conserve cash but get the acoustic performance? What can be done to make triple glazed sash windows efficient in an initial box frame?


One of the most significant problems we confront with triple glazed sash windows is discovering the depth in a standard frame for the triple glazed system itself. For triple glazed sash windows to be effective you need a great size cavity( air gap between the panes of glass, a minimum of 8mm but the more the much better) in the first place. this means that if you wish to set up triple glazed sash windows in to the original frame you really should have a minimum of 40mm depth, some original frames have this and some have not. Don’t worry if not, there are still lots of choices and workarounds to keep the rates practical. The other manner in which we can deal with triple glazing is by over making the depth of the sash and then rebating the face edge so that we can get the general depth required, this isn’t a sash repair work, this is performed in our workshop at point of manufacture. What this indicates is successfully cutting the corner out of the sash which permits the sash to pass the edge of the frame.

What is the spec of triple glazed sash windows?
Many frequently triple glazed units for sash windows are formed with 6.8 mm or 8.8 mm acoustic laminate glass as a base for the soundproofing, a good sized air gap( as we discussed 8mm as a minimum but preferably bigger), and 4mm float glass. This is the base for a high quality noise evidence system on a sash window and if you would really like to understand your glazing then please check the article highlighted.

Having different thickness glasses stop different noise frequencies which assists to increase the performance of your triple glazed unit. By the way, the latest concept to increase noise reduction is two panes of acoustic laminate instead of one with a 4mm float pane of glass But this can be a little excessive in a sash window because of the large weight of the window that needs to be reversed. That said, the sash can always be put on spiral balances to decrease the expense of system however it’s popular that this system is as long lasting or quality is a traditional sash cord and weight. Sash cords can actually be replaced by the house owner, whereas spiral balances are even more tough and need a specialist.

Do triple glazed sash windows look any different to initial single glazed sash?


The excellent feature of our triple glazed sash windows is that over the years we’ve managed to establish them so they almost appear like single glazing front on. If you’re to take a look at are triple glazed sash windows from straight you would hard-pressed to tell the difference between them and single glazing. The greatest hand out, is the truth that there’s a reflection from the several panes of glass, otherwise you would not really understand that these have actually got a triple glazed system inside, much in the same way as we manufacture double glazed windows.

Triple glazed sash windows set up into the initial frame.
Above is a photo of a triple glazed sash window that’s been set up into the original frame. This has actually undergone the treatment discussed above of having the face edge of the top sash rebated to allow for a thicker sash that the frame could usually carry, this way we have the ability to increase the size of the of the triple glazed system and the outcome was impressive, particularly because this home was over a flight path. Whilst it didn’t totally get rid of the noise of an aeroplane, it actually made a significant distinction and dulled the noise to the point the noise remained in the background. You won’t cut noise to no due to the fact that as efficient as the glazing is, the sound can still come through walls and roofing too but it’ll definitely improve things substantially.

How much do triple glazed sash windows cost?
Normally triple glazed sash windows cost around ₤ 1300- ₤ 1500 when set up into the original box frame. This represents around 35% more than double glazed sash windows. This expense is just a case of the glass being more costly along with there being an additional counterbalance expense. If you think about the 8.8 mm glass is double the weight of 4mm glass, it substantially increases the amount of counterbalance lead required to make the window sat tight when you open it. If you totally replace the sash window consisting of package frame too then the cost will begin with anywhere from ₤ 2500 pounds per sash window.

There is a fringe benefit to whole replacement, and that is that the noise reduction is a little much better due to the fact that where we manufacture a perfectly square brand-new frame, the sash seals to the frame a little bit much better considering that bit additional performance. Ultimately, triple glazed sash windows into the original frame is better value for money however not quite as efficient as a totally new triple glazed sash window. Pound for pound though, triple glazing into the initial frame is far better value for cash when considering the decibel decrease per pound invested.

If you’re truly battling with sound pollution and in particular situations I’m aware of the situation where clients actually can’t even oversleep their own house in the evening, and you desire the absolute highest quality sound reduction possible then that would be to have two panes of acoustic laminated put together as a quadruple glazed system. This seriously cut the amount of noise pollution but the disadvantage of course is the cost. This lemon glazing can set you back from anywhere from ₤ 3500 per window if completely changed.

There’s little point in using the initial frame in a circumstance where you’re going for Absolute noise reduction due to the fact that you can’t get the perimeter seal to be as perfect as a new There’s little point in using the original frame in a situation where you’re going for outright sound reduction since you can’t get the perimeter seal to be as perfect as a new box frame. If you understand how acoustics works, then you’ll realise it may be worth actually sealing the window closed.

However one should consider that there requires to be a fire exit along with conforming to all guidelines and we can not make an illegal set up. If you have more than one window in your room then it may well deserve sealing one shut so that you can definitely maximise the sound reduction and have no spaces around the glazing. Remarkably the spaces around glazing contribute to a substantial percentage of all of the sound pollution that actually survives the window. That’s why setting up a comprehensive draught proofing system is so crucial in combination with this acoustic glazing. As soon as you’ve installed this triple stroke quadruple glazing, the next thing to do is to set up a secondary glazed sash window over the top of this. This definitely guarantees that you minimise the quantity sound coming through the window totally. All that will be left, is the sound that comes through the walls and ceiling.

Frequently Asked Questions About Purchasing New Windows

How do you choose whether to fix or replace your old windows? Learn your options to purchase replacement windows, relative expense, and efficiency of repairs and how to evaluate whether a window should be conserved or gotten rid of.

New Windows?
New windows provide a host of benefits-smooth operation, low maintenance, less drafts, much easier cleaning and modest energy savings. They’re expensive, so assess the repair and maintenance options for your old windows prior to taking the plunge.

Tough question. New windows are tempting because they offer a lot– smoother operation, lower maintenance, energy cost savings, fewer drafts and simpler cleansing. They’re costly, and pros charge nearly as much as the expense of the windows to install them, which is a major financial investment.

Ask yourself the following 3 concerns to examine your old windows and weigh the advantages of brand-new ones.

Are your old windows a trouble?


Are you sick and tired of nursing your windows along, or are you OK with the small upkeep tasks that support them? Think about:

Reduce of operation. Do they raise, swing or move quickly, or do you hesitate to open them when you want ventilation?
Scraping and painting. Painted windows need routine maintenance. Otherwise they’ll rot and break down. New windows with aluminium or vinyl cladding or that are made from vinyl or a composite eliminate this task.
Condensation. Does condensation regularly collect on the glass, cloud the view and soak the window trim? Higher-efficiency glass in brand-new windows will help in reducing this issue.
Storm windows. Do you mind cleaning, preserving and setting up and removing storm windows? Do your storms need replacement?
Cleaning up. Is this so challenging that you prevent doing it? Many new windows are designed to make cleaning a snap.

Are your old windows in working order?


Single-pane windows often leave spaces feeling chilly and dry in cold weather and overheated in warm, bright weather. Windows with double-pane glass can greatly enhance the comfort of your house. They can block much of the heat of direct sunshine however still allow the light to come through (less need for tones). They’ll minimise cold drafts and the chill of cold glass. And they’ll reduce condensation so you can keep the indoor humidity at a higher, more comfy level in cold weather. New energy-efficient windows will also minimise your fuel bills however hardly ever adequate to justify the investment if your old windows are still in good shape.

Are your old windows worth repairing?
You can almost always repair and restore old windows if you’re ready to set aside the time and can find replacement hardware. However it’s not constantly worth the effort and cost. Significant issues consist of:

Rot. When rot starts, it’s difficult to stop unless you commit yourself to replacing decomposed wood (a difficult task) and then preserving it routinely. Consider replacement.
Sagging casement (crank-out) windows. You can normally change worn-out crank mechanisms, however bent or used hinges are tougher and replacements do not constantly resolve the issue. Consider brand-new windows.
Fogged double-pane glass. The fogging that occurs between the glass panes can’t be repaired. Glass replacement (sometimes the entire sash) is the only service. This is typically tough and it’s pricey if a pro does it. Compare the “fix-it” cost with the expense of a new window.
Hard-to-find replacement hardware. Call the window producer or regional window dealership if you can recognise the window brand and model number. Lots of hard-to-find parts are available from online providers. But frequently brand-new windows are the only option.


What’s the very best way to change my windows?

Option 1
Wood or vinyl window inserts cost about the like total new window systems but are easy to install because you leave the old frame and trim undamaged.

Option 2: The easiest way to replace windows is to eliminate the old sashes and slip a window insert into the old frame. You get the benefits of high-efficiency glass, weather-tightness and a maintenance-free exterior with very little impact on the look of your home.

To begin the procedure, simply determine the frame and order a brand-new wood or vinyl system to fit it. This constantly works for double-hung (slide up and down) windows but only often for casements (crank out) and moving windows A window dealership will recommend you on your choices. Or you can opt for sash replacement, which works for double-hung only. You can complete the changeout this way in about an hour per window (or much less after finding out the ropes on the very first one!). But this technique has numerous disadvantages. The old frame must be rot-free and reasonably square. And you still have to keep the exterior wood frame and trim.

Option 3: Completely tear out the old window and frame and put in a new one. You normally need to go this path with sash and slider windows. This project takes longer and is more difficult because you have to remove the exterior and interior trim, make the brand-new window weathertight and then change the trim. Plan on spending an entire day per window.

On the plus side, this approach enables you to begin fresh with a new, weathertight, low-maintenance window. And you have the choice of reframing the opening and altering the window size while you’re at it.

Bear in mind that complications can emerge if your old window does not have outside trim. Sometimes brick, stucco, vinyl siding or other siding materials butt right up against the window frame. In these scenarios, you might have to get rid of or cut siding to get the old window out and the brand-new one in, and after that patch or restore siding to finish up.

Should I replace them at one time?
Balance your house’s look with your budget plan. Even if you try for a close match, new windows will most likely look a bit various from the old. And even the glass itself (we advise the low-E) normally looks rather various from clear glass. So replacing one or two in a conspicuous location may look bad. One great strategy is to change all the windows on one side (or level if you have a two-story house) to retain a constant look. Frequently the windows on one side of a house degrade much faster than the others.

How do I kmow I’m getting a good-quality window?

Look
It may be tough to find a specific match for an old window without paying a fortune for a special order, but many styles are readily available as standard options from different window manufacturers, and you can normally find a window that mixes well with your home design.

Buy replacement windows:
Quality showrooms. We strongly suggest that you go to a show room where you can compare windows of different brands or different designs within the same brand name to purchase replacement windows. Examine these features and address these questions:

Appearance. Picture the windows in your house. Does the style of the windows mix well on the interior and exterior? Are the wood or vinyl joints well made? Do the muntins (grids that divide the glass) fit securely and cleanly? Is the hardware appealing? Unless you’re trying to match existing window colours, choose a low-maintenance outside (such as vinyl or aluminium) so you’ll never ever have to scrape and retouch the paint.

Operation. Try the display windows. Do they open and close efficiently? Are the cranks, runners and locking devices solid and do they look as though they’ll hold up against heavy usage? Does the window lock strongly without too much effort? Does the weatherstripping fit snugly? Are the screens solidly developed and simple to get rid of?

Cleaning up. If cleansing is a top priority, can you easily reach both interior and exterior glass? Eliminate or turn the sashes to evaluate them.

Service. Are parts readily available if something should break or wear out? Can you replace the weatherstripping when it breaks? Both these questions prefer window companies with long track records since they’ll likely serve their customers well into the future. If the glass breaks or fogs, how hard and pricey is replacement?

Service warranties. Compare the warranties for parts and finishes. Most likely the most aggravating (and costly) issue is the failure of the seal between double pane glass and the resulting fogging. Look for a service warranty that covers glass replacement up to twenty years. Note: Keep the receipt for your window purchase and the warranty in your records.

Glass choice. Energy-efficient double-pane glass is relatively standard now. It’s practically constantly worth paying a bit extra for two extra features: a low-E finishing and argon gas between the panes. Many makers have 2 variations of this type of glass, one created for cold climates and one created to control sunshine in warmer environments. If you invest more for a/c than for heating, choose the warm-climate type, and if you invest more for heating, pick the cold-climate type.
