Straight answers

Four we get asked every week

Doors and windows is one of nine trades out of the Harrow yard.

Repair the sashes or replace them?

If the timber is sound, overhauling is cheaper, warmer than you think once draught-proofed, and keeps the window the house was built with. We only quote replacement when the frame has gone.

Just one misted unit — will you come?

Yes. We measure it, order the unit and swap it in half a day. No minimum order and no salesman with it.

Do you register the glazing?

Where it is replacement glazing, yes — FENSA registered and the certificate comes to you, which is what a buyer's solicitor asks for.

Can you make good after the fitting?

Sunil skims the reveals and Karolina paints them if you want it finished properly. One firm, one invoice, no waiting on somebody else.
