Local Detail
Bi-fold doors fitted across Gravesend
Gravesend has one of the densest concentrations of Victorian terraced housing south of the Thames — narrow streets, original sash windows, and a council that takes the conservation areas seriously. Careful timber-effect replacement is normally the right answer for windows facing the street.
Northfleet and the DA11 stock leans more toward 1930s semis and post-war housing, where standard replacement window programmes are more typical. We carry a full product range into Gravesend — from period-friendly timber-effect through to modern aluminium.
The Thames riverside aspect adds a salt-air consideration on north-facing properties. Marine-grade powder-coat is recommended on aluminium near the river. Gravesham Borough handles building control; quote slots typically inside five working days.
Housing stock we work with here: Victorian terraced housing in central Gravesend, 1930s semis through Northfleet, post-war housing in Singlewell, and conservation-area constraints throughout the older centre.
Our vans are around Gravesend Pier, St George's Church, the Thames riverside most weeks, so survey and aftercare visits in Gravesend are easy to diarise.

What goes wrong
Bi-fold problems we get called out to in Gravesend
Draughty original sash windows
Universal across Gravesend's Victorian terraced stock. Slim-profile timber-effect replacements solve the draught and the noise while keeping the period look.
Listed and conservation-area restrictions
Strict in central Gravesend. We confirm consent requirements at survey and specify sympathetic timber-effect replacements where required.
Salt corrosion on river-facing aluminium
Properties facing the Thames need marine-grade powder-coat. Standard polyester degrades visibly within 5 years on north-facing aspects.
Damp-staining around old timber cills
Decades of paint over rotted timber finally giving up. Either splice and repair or full replacement — we'll quote both honestly.
