Grantham's town centre — Castlegate, Westgate, Swinegate, North Parade and the streets around St Wulfram's — is a mix of Georgian and Victorian brick and stone with a large stock of original timber sash windows inside the conservation area. The Victorian villas along Harrowby Road, Dudley Road and the roads towards the station add the later, larger sashes of the railway town.
We restore them rather than replace them. Rot is cut out and spliced, cords and weights renewed, perished beads and putty replaced, cracked glass reglazed, brush-pile draught seals fitted and the window repainted properly. New sashes, where the originals have been lost, are made to the surviving pattern and fitted into the existing box.
We cover Grantham and the villages around it — Great Gonerby, Barrowby, Harlaxton, Belton and Ancaster — and the Vale of Belvoir towards Melton Mowbray.

Structural sash window restoration
We replace rotten timber and repair damaged frames and sills. Where the decay is localised we cut it out and splice in matched new timber; where it is shallow, a two-part epoxy repair consolidates the wood. Either way the original frame stays in the wall.
Sash window redecoration in Grantham
A restored window needs a proper paint system to stay restored. We strip failed paint back to a sound surface, prime bare timber, fill and sand, and finish with a durable exterior system — by brush or by spray for the smoothest finish.
Draught-proofing in Grantham
We fit discreet brush-pile draught seals to the existing sashes — routed into the parting and staff beads and the meeting rail — so the window sits snugly, stops rattling and keeps out cold air, dust and street noise without changing how it looks.
Functional repairs
Snapped cords, dropped sashes, seized windows and rattling glass are everyday work for us. We re-cord with waxed cotton cord, rebalance the cast-iron weights, ease and adjust the sashes and re-putty loose glass so the window opens, closes and locks as it should.
Problems we can help with
- Sash windows in need of repair or restoration
- Windows that are difficult to open or close, or painted shut
- Draughts, rattles and street noise through the window
- Sashes that will not stay up, or drop shut
- Rotten or decayed timber frames and sills
- Paint that is cracking, flaking or peeling
- Missing, cracked or misted glass panes
- Loose or missing putty
A cost-effective alternative to replacement
Restoring an original sash window is nearly always a fraction of the cost of replacing it, and the repaired window — dense, slow-grown timber with a modern paint system and draught seals — will usually outlast a new one. We quote for each window individually after a survey, so you know exactly what is being done and why.
