We can restore even the oldest period sash windows to their former glory.

Sashes have become an increasingly popular addition to both new and older properties, replacing existing windows and providing a wide range of additional benefits. Whether they are made to match period properties or designed for modern offices, they are beloved for a reason. Each of our projects is entirely bespoke, built to match the client’s needs and preferences exactly.

What is a Sash Window?

These are windows designed in two distinct parts, with the lower pane sliding up over the top pane instead of swinging outwards. Not only are these windows a beautiful addition to many homes, but they have multiple practical benefits that other types can sometimes lack.

How do Sash Windows Work?

These windows are often designed with a weight system. A weighed internal mechanism allows the bottom pane to lift upwards, sliding vertically so that the bottom pane slips over the top one. Certain designs replace this weight system with springs or even electrically powered motors.

Sash Window Costs

Window costs can vary heavily depending on the work that you’re having done, the complexity of the windows themselves, and the materials being used in the project. No two windows will cost the exact same amount since each client’s needs are slightly different.

General Costs

However, knowing a general price baseline makes a big difference. Here are the expected prices for typical windows, without any major changes or additional extras. 600 x 900 sashes can cost between Β£480 and Β£1,500 1200 x 1200 sashes can cost between Β£1,200 and Β£1,800

Cost Variation

Of course, these prices are only vague at best and don’t represent every project. We can often offer sash windows that are cheaper than average – contact us to get a free quote and a breakdown of how much your project might cost, as well as reference prices from similar recent projects.

Bespoke Sash Window Suppliers

Our bespoke sash windows are all designed to fit with the client’s personal needs, whether that’s in terms of style, size, or materials. Windows and doors are an important part of retaining a home’s style, and we can offer complete replacement of classic sashes while still retaining the original function and design.

Classic Designs

A lot of new buildings still adhere to British design heritage, with listed buildings, in particular, having a very strong focus on aesthetics. Whether you live in a listed building or just want your home’s visuals to be left unchanged, we can offer traditional timber sash windows that perfectly fit your needs.

Modern Windows

On the other hand, we can also create modern options, moving away from period windows and doors into something that fits better with a modern home. It all depends on what our clients ask for.

Types of Sash Windows We Offer

We have a wide range of different windows on offer. If you can’t easily choose, sash window experts like ours can break down the benefits and drawbacks of each style.

Box Sash Windows

Box sash windows are the most basic choice. They are simple windows without any other obstructions, making them the default option that many people decide to use if they want a clear, single-section lower pane to look through. These fit well with most glass doors.

Spring Sash Windows

Spring sash windows take a box sash and replace the weighted system with a spring. This spring allows for easier opening, effectively spring-loading the mechanism – which also reduces the overall bulk of the frame and makes it a much slimmer choice.

Georgian Sash Windows

Georgian designs are made with a ‘six on six’ design. This means that both panes are split into six distinct ‘spaces’ with grid-like struts, the same design that many beautiful period windows still show off.

This makes them the common option for traditional sash windows but doesn’t actually have a direct benefit on the window itself. They can occasionally be used on some intricate French doors, too.

Victorian Sash Windows

A Victorian window swaps the ‘six on six’ for ‘two on two’, cutting the lower and upper panes in half. This is a very common sight with old windows, but also tends to appear in modern British houses often too. Again, the difference is mostly cosmetic. Some front doors may also use this as windows.

Edwardian Sash Windows

Edwardian sashes are a combination of the other two options, using a ‘six on two’ design. This means that the top pane is split into two rows of three, although there isn’t a specific arrangement or pattern for how this is done.

The bottom pane is often completely clear in these windows, meaning that they still have all the visibility of a box design. However, this isn’t always the case, and it heavily depends on the design. Some doors also use a design similar to this.

Sash Window Frame Materials

High-quality materials are important when working with these designs, even if you don’t need any repairs. Nearly three-quarters of all original traditional sash windows are gone, including the timber windows, usually due to wear and tear or poor maintenance.

Good materials make a huge difference, and our sash window experts can offer multiple choices.

Timber Sash Windows

Timber windows are another design meant to replace wooden windows, mostly by using real wood (specifically, toughened timber) and adding additional finishes to help protect it. These can be better than even uPVC frames and offer much more character, but they also tend to be more expensive.

Sash Window Glass Types

Using clear or frosted glass in one of these windows will not make a significant difference to the draught-proofing or other core details, but it can still be a big decision to make. Switching from one to the other after installation is much harder than deciding ahead of time.

Clear Glass

Clear glass gives you an unobstructed pane but also means that you don’t have any inherent privacy without curtains or something else to cover the window up. Most people use these for rooms where curtains and blinds are common, like the living room. Clear glass also appears on many single doors.

Frosted Glass

Frosted glass trades a clear view for excellent privacy, scrambling whatever’s on the other side. These are more common in bathrooms, French doors, front doors, bathroom/shower doors, and other private areas but are also a great addition in terms of aesthetics.

Frequently Asked Questions

Can Sash Windows be Double Glazed?

Double glazed windows offer excellent draught proof surfaces and can increase energy efficiency in a way that reduces your energy bills. This energy efficiency is easy to install on sash windows – double and triple glazing are both viable options with most windows.

Do Sash Windows Need a Lot of Maintenance?

Most windows don’t require much maintenance. However, our sash window experts can give you a breakdown of how often you might need to check the window itself. Certain materials wear down faster than others.

Are Sash Windows Worth It?

While sash windows might not seem that different at first, they can be very receptive to additional benefits like draught-proofing and double glazing. Our sash window experts can help you find the perfect window options for your home.

Can Sash Windows be Replaced?

We can easily replace sash windows with fresh designs or even replace existing windows, including casement windows). Major alterations, like replacing old single doors with these windows, are also possible.

What Material is Best for a Replacement Sash Window?

There isn’t a single best material for creating windows like this. Just like French doors and other home additions, it all depends on the style that you want, as well as your budget.

Should I Repair or Replace my Sash Window?

Sash window repairs are cheaper than full replacements. However, if you can’t repair sash windows that have been heavily damaged, a replacement is also very easy for our expert teams. However, we will always suggest a repair as long as the repair is a viable option.

Emergency Sash Window Repairs

We can sometimes offer some short-notice repair methods if a window breaks unexpectedly. Contact us for more details.

How do you Clean Sash Windows?

There is no special method for cleaning these windows, even if they have double glazing or are connected to casement windows.

What Is the Difference Between Sash and Casement Windows?

Casement windows fold out while sash windows slide upwards. Sash window experts can also install casement windows and certain doors as needed since they’re very similar – as a family-run business, flexibility is important.

Sash Windows Benefits

Sash windows offer better ventilation, more charm and can sometimes benefit more from draught-proofing services and water ingress prevention. This makes them more energy-efficient in certain situations.
