The common sash window issues that we can solve for you

Old wooden sash windows are notorious for rattling and letting in draughts. This is because when they were first installed, home construction technology had not advanced to what it is now. Sash window repair in London is a very viable option.

Obviously, people weren’t able to draught proof their sash windows back in the old days. The best they could do was put on a roaring fire and cover their windows with thick drapery.

Fortunately, you won’t have to apply these hazardous solutions any longer. Once we’re done with repairing your sash windows, we guarantee that you won’t hear them rattling away whenever there’s a gale outside. Sash window draught proofing has been around for twenty years but is pretty much spot on at keeping the draughts at bay.

Those cold spots all over your home? Gone. We’ll take care of those too.

We know that during winter, it takes up a lot of energy to heat up a space that never seems to get warm enough.

By draught proofing windows, your home becomes more insulated and easier on your home’s HVAC system. It won’t have to work as hard, regulating the temperature indoors.

What does this mean? No more insanely high electric bills during the cold winter months.

We do this by installing discrete draught proofing brush piles between the parting and staff beads that hold the panes of your sash window in place.

Trust us, this is going to go a long way in the insulation of your home. It will keep the warm air in and the cold air out.

All Londoners know that it rains around a fourth of the year, so it’s you’ll still be a bit chilly even when it’s not wintertime.

Having all your sash windows draught proof will have a dramatic effect on the temperature of your home.

You won’t have to keep getting up in the middle of the night just to turn up your thermostat ever again.

Another problem that people usually encounter with sash windows is that they can sometimes get increasingly harder to open and close over the years.

This most likely because of a worn or broken sash cord. Sash windows usually have four sash cords within its sliding mechanism.

It’s advisable that you get all four replaced when you’re having trouble opening or shutting your sash windows.

But that’s not all that could be wrong with a sash window that’s hard to operate. Sometimes, after years of use, the pulley wheels get worn down. You can tell that this has happened when the sliding panel doesn’t hold up on its own anymore.

You’d have to prop it up with something, otherwise it’s going to remain permanently shut.

Another issue is the misalignment of parting and staff beads. To resolve this issue, we usually make faithful replicas made out of the same material that your frames are made of.

Or perhaps you’re just bored with how your sash windows look and you want to refresh them with a new coat of paint or varnish. We can also take care of that for you.

When you call on us to repair your sash windows, we go the extra mile in checking every aspect of what makes a perfectly functional sash window.

We won’t just focus on whatever issue you’re brought up with us. We’ll do the extra work and assess the sash window’s overall condition.

This is so you’ll know if ever some parts do need replacing. We want to make sure that we leave you with sash windows that can protect and beautify your home.

A brief history lesson on sash windows and how they’ve gotten better throughout the years

Evidence of the first sash windows date back from as early as the 16th century. They were found all over Europe because of the simplicity of their design.

Back then, sash windows were a bit different. The panels could only slide horizontally. As time went on and their popularity grew even more, various new styles started popping up from everywhere.

Of course, the mechanism that was used to operate the sash window also became a bit more sophisticated. They’re still hadn’t become the sash windows that we know today, but at least they were able to opened vertically.

This was done by drilling holes along the side of the frame and the panels has matching pegs to fit them onto. Not quite as sophisticated as the pulley system that we use now, but they were starting to get the idea.
An issue that most old wooden sash windows had was the panes. Glass just wasn’t strong yet back in the old days and they were very prone to cracking.

So to troubleshoot this issue, they used to us multiple panes in sash windows. To give you an idea, an old sash window from back then would have as much as ten panes of glass.

Obviously, the smaller the pane, the less likely it is to break.

They also had to use glazing bars and they had to make it thick to make sure that the sash window remains stable. That’s why they didn’t look very nice.

But once the Edwardian era came along, so did innovations with glass. Panes were a lot stronger and the glazing bars didn’t have to be as large.

Sash windows with just one or two panes started appearing in homes too because they didn’t crack so easily anymore.

Plus, this was a time when less was not more. People wanted to parade around their wealth by having very ornate furnishings and fixtures installed into their homes.

In fact, a very popular request to window manufacturers back then was for them to build floor length windows.

Since the quality of glass improved greatly, they were able to fulfil these requests. These large windows were usually made of just two sashes, the upper one made up of stained glass for a more refined and classy look.

And so the sash windows that we know today came to be. If there’s one thing to be said about this type of window, it’s that it has always been incredibly durable.

Of course this is now truer than ever because the technology that goes into improving sash windows have not stopped progressing since then.

But we’ve learned a lot from these old designs and the one thing that remains true is that if it’s made of hardwood, it’s going to last a long time.

That’s why even today, people opt to have their sash windows made out of solid hardwood. Hardwood is extremely sturdy.

Wood manufacturers condition and treat wood products before they are sold. This protects them from warping, rotting, shrinking and swelling.

In fact, the technology has gotten so good that people are now able to have wooden sash windows made with a warranty of up to 50 years.

Now that sounds like a good investment. If you want to improve the quality of your home, not only for your comfort, but to increase its value as an asset, choosing hardwood sash windows is a very smart move.

Granted, you’re going to have to pay more money for high quality products. But this is the kind of investment that will eventually pay for itself.

Just to illustrate just how strong sash windows are – remember the Ham House in the south of Richmond?

Sash windows were installed there as part of a renovation back in 1670 thanks to Duke and Lady Lauderdale.

Guess what, you can still see these original windows to this day. Of course, along with the rest of the estate, they’ve been preserved and well maintained over the years.

The point is, with the right materials and the proper care, a high quality sash window will last for many generations to come.

The benefits of a sash window

Sash windows became very popular because they were (and still are) very easy to clean and replace, both of which can be done from the inside. That means there would be no need to set up scaffolding.

A lot of people are just used the benefits that they get from sash windows without even being aware of them, so some of these might be surprising.

You won’t really have to do much to maintain them.

If you let a reputable company like us manufacture your sash windows for you, you’re not going to have to do much in the way of maintaining them.

This is because we would use high quality materials that will rarely ever have to be replaced, if at all.

To maintain a sash window, all you have to do is check to see how well it’s functioning. That’s all. If the wood is looking a little dull, then you might have to apply a coat of varnish on it.

Other than that, you just really have to keep it clean just like everything else in your home.

But this is if you choose sash windows made of hardwood and metal. There are some options out there for PVC and vinyl sash windows, which could be attractive to some.

These alternatives might be cheaper, but they’re not very repairable. If something goes wrong, there’s not much a repair service can do other than replace the whole unit.

That’s why it wouldn’t be so economical to go this route. Yes, they would be cheaper as a one-time purchase, but it’s very likely that you’re going to have to keep repurchasing them.

What’s worse is that they’re not ecofriendly like wood or metal. If you decide to replace your wooden sash windows instead of refurbishing them, the old wood can still be put to use.

In fact, a lot of people would pay good amounts of money for old, aged reclaimed wood so that they can repurpose it as something else.

PVC, on the other hand, is very hard to recycle. If you discard them, they will just end up in your local landfill. There’s no resell value and they can’t be repurposed.

Wooden sash window installation done correctly takes the edge off of the homeowner. You can rest easy, knowing that we have gone through all the lengths necessary to make sure that your sash windows won’t fail you even way into the distant future.

They’re a safer option than casement and picture windows.

Sash windows that we’ve manufactured are double glazed, meaning the panes are fortified to withstand a significant amount of force.

It would be difficult to break them, making your home a little safer from anyone who might have any bad intentions.

But even not counting burglary, you can avoid any glass related accidents from broken windows.

If you want to go even safer, we are able to install special locking systems as an extra precaution. This is added to the usual restrictor bolt that all sash windows usually have.

This is especially useful if you have kids in your house. Childproofing your home well is something every parent aims to do.

By having secure sash windows made, this is one step taken towards protecting your loved ones.

Sash windows keep the noise out.

If you live in the busier side of London, then having double glazed sash windows can help you sleep better at night or concentrate when you need to get some work done.

This is because double glazing also acts as soundproofing. Although you won’t be able to shut the noise out entirely, double glazed sash windows will reduce it significantly.

This would also be useful if you’re trying to keep the noise in. Maybe you don’t want to be a nuisance to your neighbour as you practice your instrument or have movie night with your friends.

Either way, having double glazed sash windows will help in keeping the noise pollution to a minimum.
They’re very functional.

As far as window types go, sash windows is the most no-fuss, functional there is. Unlike standard casement windows, you won’t have to oil hinges or buy separate locks.

Sash windows are there if you want to keep your home insulated or you want to let fresh air in. They can be opened widely, which is not something other windows are able to do.

There’s usually an obstruction (some bars or a limitation as to how widely a pane can be opened) that restricts airflow.

If you let a topnotch sash window manufacturer like us at Mortice & Green make your sash windows for your home, they are sure to be strong, reliable, and low maintenance.

Sash windows are versatility is unparalleled.

We’re used to seeing sash windows all over London, whether they be on period houses or modern flats.

There’s a reason why people keep using this timeless design and it’s simply because it looks simple and elegant.

If you’re still unsure about what type of windows you want installed, then we can attest that sash windows will match any sort of architectural aesthetic you’re going for.

We understand that this is a pretty big decision because windows are technically a permanent feature.

But trust us when we say that sash windows look great on building. This is because they’re not really bound to one specific style.

All of these can be classified as sash windows, but you could have ones that are more suited for that Victorian style or ones that are sleeker, simpler, and more suited for the chic modern look.

Whatever you decide on, sash windows have been around for a long time because they haven’t lost their charm. And we don’t think sash windows will lose it any time soon.

That’s what makes them a good investment.

Sash windows: a good investment.

Speaking of good investments, choosing to go with high quality wooden sash windows would be one. Why? Because they increase the value of your home.

This would be equivalent to having your kitchen renovated or having your yard landscaped professionally.

If you intend to sell your home in the future, a lot of potential buyers would appreciate a more classic approach when it comes to design. This is because it will never go out of style.

Plus, if you use high quality materials, not just with your sash windows, but with any fixture in your home, this increases the overall value of your property.

Even if you have no intention of ever selling your home, it’s a good idea to maintain your assets. It can’t hurt to improve your portfolio.

If you have a family, then this is all the more important. A good quality home is an a valuable thing you can pass down on generations to come.

Sash windows: they will protect your furnishings.

The two main purposes of a window is ventilation and protection. What you might not know is that anything less than double glazed panels will not do a good job of protecting your belongings inside the house.

Why? Double glazing lessens the heat and UV rays that enter your home. These two things can do a number on your household items because they affect fabrics and most organic materials.

This is why, for example, a patch of carpeting that is always exposed to the sun will look more faded than the rest of the carpet.

Sash windows: ventilation.

Ventilation is very important especially in areas that are always wet or where there’s usually smoke – so bathrooms, kitchens and living rooms where there’s a fireplace.

But there is such a thing as too much ventilation, especially when it comes to areas that rarely receive any sunlight like basements or maybe bedrooms.

If there’s too much condensation happening in these areas, this makes it a more conducive environment for mould and mildew to grow.

It probably wouldn’t alarm you if we say that this will negatively affect anyone’s health. Everyone knows this.

To take the precaution of stopping mould from ever forming, get double glazed sash windows. Why does this help?

Double glazing sash windows are able to collect moisture from the outside. This will make it easier for you to keep mould from forming because the area that you have to mind would be limited to your windows.

Keeping mould from forming in your home will keep you and your family healthy and who doesn’t want that?

They’re the most energy efficient.

Perhaps the biggest advantage to having double glazed sash windows is that they very energy efficient.

When we install sash windows, we automatically include draught proofing, which essentially keep the warm air in and the cold air out. This is, of course, when the windows are closed.

You don’t want your living spaces to be too stuffy in the summer.

But since we live in a cold climate, heating is something that we spend a lot of money on especially during the winter months.

The problem with windows that have not been draught proofed is that it makes us turn up the heating even more.

Your home HVAC system will have a harder time regulating the temperature in your home.

What’s unfortunate about this is that this problem is so preventable. Instead of paying high electric bills, you should just get the panels of your sash windows replaced.

Good home insulation can save you a lot of money. In fact, if everyone in London were to do this, we could save enough energy to heat up to 400,000 homes.

That’s a lot of wasted energy. All just because your existing sash windows aren’t doing a very good job at keeping the cold air out of the house.

It’s also worth mentioning that wooden sash windows are sustainable and we’re very ecologically aware of how we manufacture them.

Sash windows made of other materials like PVC or vinyl take as much as 8 times more energy to manufacture. That’s not really helping the environment at all.

Yes, some might argue that you would have to cut down trees to make wooden sash windows, but they will last you a long time. That means you’re not going to keep buying wooden sash windows throughout your life.

Ideally, it’s a one-time thing.

PVC sash windows, on the other hand, will definitely have to be replaced. That’s a guarantee. This is because PVC doesn’t hold up against weather very well. It’s damaged by heat and cold.

We’d be surprised if a PVC window lasts you 10 years. So with that line of thinking, wooden sash windows are lot more economical and ecologically sound.
