New Sash Windows Supplied and Fitted in Southfields

Two new white sash windows fitted in a Southfields bedroom, with patterned blinds above and views over neighbouring gardens

Not every project we take on is up on the roof. A homeowner in Southfields asked us to supply and fit two new sash windows in a bright top floor bedroom, replacing the original wooden sash windows, which had reached the end of their life.

Out with the old

The existing wooden sashes had served the house well, but it was time for them to go. Each window was carefully removed in turn, keeping the opening tidy and protecting the room, with its decorated walls, blinds, and furniture, throughout the work.

Fitting the new sash windows

The two new sash windows were fitted, levelled, and sealed into the prepared openings, then finished neatly against the existing sills and reveals. The room’s blinds went straight back up, and the finished result looks like it has always been there, just crisper, smarter, and smoother to operate.

The finished result

Two tired wooden sashes are now two smart new windows, keeping the classic sash character of the house while opening and closing exactly as they should. The bedroom keeps its lovely outlook over the gardens of Southfields, now framed by windows that match it.

Frequently asked questions

Why replace old wooden sash windows?

Original timber sashes are beautiful, but decades of weather take their toll. Common problems include draughts, rattling, sticking sashes, rot in the frames, and single glazing that leaks heat. Replacing them restores smooth operation and a crisp appearance while keeping the classic sash look that suits period streets.

Will new sash windows keep the period character of my home?

Yes. Modern sash windows are designed to replicate the proportions and sightlines of traditional sliding sashes, so the character of the house is preserved from the street while the windows themselves perform like a modern product.

What does a sash window replacement involve?

The old sashes and frames are carefully removed, the opening is checked and prepared, and the new window is fitted, levelled, and sealed. We then make good around the frame inside and out, so the finished window sits neatly against the existing walls, sills, and decoration.
