Our Approach

Traditional sash windows are a beautiful addition to any building but, unfortunately, age and lack of proper maintenance can see them lose their charm.

Unloved they may have been, but no matter what the problems are – you don’t need to give up on your sash windows just yet.

Even if they are draughty, rattling or showing signs of rot, traditional sash windows can now be returned to all their former glory and improved upon.

They may look awful and have been terribly neglected over the years but sash windows were built to last.

It just takes a little care and attention from skilled craftspeople to bring them back to life.

There are several common, but very solvable problems that people experience with old or poorly maintained sashes.

Firstly, the windows may be jammed shut. It could be that the sash cords are frayed and no longer work or the opening may have been painted over to keep them shut.

Another issue is draughts, –and no one wants draughty windows.

According to the Fairco experts, draughts are mainly caused by badly aligned sashes and a lack of compression between the sashes.

Woodwork will rot over time mainly at the sills and the rails particularly at the bottom of the window.

Also the window hardware, such as the original brass fittings, could have become worn, broken and pitted over time.

The putty could have fallen away over the years and there might be small cracks in the glass, this is particularly common in Edwardian sash windows.

How we do it

Remove and inspect the sashes

Clean any rot from the sills and boxes

Repair or replace the wood the sash weights

Check that pulleys are working correctly  

Fit new sash cords

Install draft-proofing brushes and beads

Replace broken catches

Sometimes, on first inspection, we find that the sashes are beyond repair. If in this case, we will give you a detailed quote and the cost of making, painting, glazing and fitting new sash windows will be included.

Occasionally, we will not be able to ascertain whether the sashes will need to be replaced until we have taken the window apart. However, we would always agree any additional costs before continuing with the work.


Draft-proofing your sash windows is a surprisingly effective way to make your house feel instantly warmer.

A typical sash window will allow warm air to leak from your room similar to the way a hole allows water to leak from a hose. Without draft-proofing , it is not uncommon for the air in a room to be changed 3 times in 1 hour .

This means that you can be paying to heat the air in your room again and again and again. The draft-proofing that we install to your sash windows will not change the look of your windows as it is very discreet and will make your house warmer.

Sound insulation

Noise can be a big problem, particularly if you live in an urban area.

To reduce the impact that noise can have on your comfort levels at home, we recommend sound proofing your sash windows by installing acoustic glass.

In most cases, we would simply replace the existing sashes with acoustic glass sashes that fit within your existing sash windows boxes.

We offer two types of sound-insulated glass. Both solutions can easily be fitted to your existing sash windows without compromising the look of your home.
