How much does sash window restoration actually cost?

It’s one of the first questions people ask, and also one of the hardest to get a straight answer to.

The reality is, the cost depends on things like:
• the condition of the windows
• how many need work
• whether repairs or full restoration is required

But in many cases, restoring original sash windows is more cost-effective than replacing them, especially when the structure is still sound.

In our latest article, we break down what affects the cost and what you can realistically expect.

We recently carried out specialist sash window works at Princess Park Manor, London. This well-known historic residential development is set within a Grade II listed building.

Projects like this require a careful balance between preserving original features and improving performance for modern living.

Our work focused on restoring and refining the sash windows across the development, helping ensure they operate smoothly while maintaining the character of the building.

It’s always a privilege to work on properties of this scale and heritage.

Original sash windows are there for a reason, and in most cases, they’re worth preserving.

We often speak to homeowners who assume that draughty or worn windows need replacing. The reality is usually very different.

With the right restoration work, original timber sash windows can:
• operate smoothly again
• reduce draughts
• improve comfort
• and retain the character of the property

At Brown’s Sash Windows Restorations, our focus is always on preserving original windows wherever possible, rather than replacing them.

In our latest article, we explain why original sash windows should be preserved and how restoration improves performance.

Can you double glaze existing sash windows?

Short answer: yes...but not always. This is where a lot of homeowners get bad advice.

In many cases, original timber sash windows can be upgraded with slimline double glazing, improving insulation and comfort while keeping the original look. 

But here’s the part most people don’t get told:

• Not every window is suitable
• Some frames can’t take the units
• Listed and conservation rules can limit what’s allowed

That’s why it’s not a “one size fits all” job.

In our latest article, we break down:
• when double glazing works
• when it doesn’t
• and what your real options are

Ever wondered how sash windows actually work?

Most people don’t think about it — until something goes wrong. Traditional sash windows use a clever system of cords, weights and pulleys to allow smooth opening and closing.

When everything is working properly, the window should move easily and stay open at any height. But over time, wear and tear can cause issues like sticking, rattling or windows dropping shut.

At Brown’s Sash Windows Restorations, we regularly repair and restore these systems so original windows can work as they should again.

In our latest article, we explain how sash windows work and why they can often be restored rather than replaced.

How long do timber sash windows actually last?

It’s a question we hear all the time — and the answer often surprises people. Many original sash windows can last 60, 80 or even 100+ years, especially when they are properly maintained and restored.

At Brown’s Sash Windows Restorations, we regularly work on windows that have been in place for generations. With the right repairs and draught proofing, they can continue to perform well for many more years.

A recent project we completed in Belper town centre, Derbyshire involved a full sash window restoration on this striking period building.

The property still retained its original timber sash windows, which are a key part of its character. Over time, they had become draughty and difficult to operate, so we carried out a full restoration along with discreet draught proofing to improve performance while keeping the original look.

Projects like this show how traditional sash windows can be restored to a high standard, even on prominent town centre buildings.

Are your sash windows letting in cold air?

It’s one of the most common issues we see, especially in older properties. Small gaps, worn components or lack of draught proofing can all allow cold air to enter — making rooms feel uncomfortable and harder to heat.

The good news is that in most cases, this can be fixed without replacing the windows.

At Brown’s Sash Windows Restorations, we restore and draught proof original timber sash windows so they keep their character while performing far better.

In our latest article, we explain why sash windows let in cold air and how it can be resolved.
