Working Windows, Without the Disruption

Old windows come with old problems. Sashes that won’t budge, cold air finding its way through tired frames, double glazing that’s gone milky and opaque, these are the kind of faults that chip away at your home day by day.

If any of that sounds familiar, you’re in the right place. We offer sash window services to repair and restore your original timber window frames to full working order, using period-appropriate techniques that keep the historic details intact like the mouldings, proportions, and profiles that give your home its character. It costs less than replacement, far less disruption, with no ripped-out reveals or weeks of mess.

Not sure which applies to your windows? Get in touch with us directly and we will advise you on what service best suits you.

Do you work on listed buildings?

Yes. There’s genuine experience working within conservation area and listed building regulations, and the techniques and materials used are chosen carefully to preserve the period character of your windows while improving how they perform day to day.

Can sash windows be repaired rather than replaced?

In most cases, yes. Worn cords, draughts, and rattling sashes can typically be sorted without touching the original frames. Full replacement is far less common than most customers expect.

How do I know whether I need repair or replacement?

It comes down to the condition of the frames and sashes themselves. Rot, significant warping, or extensive structural damage may mean replacement is necessary, but most faults fall well short of that. After assessment, we’ll always point you toward the most cost-effective route.
