Sign Windows in Daventry
Daventry is a market town in West Northamptonshire with a small historic centre around High Street and Sheaf Street, where many buildings go back to the 17th, 18th and 19th centuries. From the 1960s the town grew fast, with large estates built under an overspill agreement with Birmingham, and new developments have kept appearing on the edges since. That gives Daventry a real mix: period cottages and townhouses, 1960s and 1970s homes, and modern estates. Many of the post-war houses are on their second set of windows by now, and owners usually want to cure draughts, misted panes and stiff locks, or swap a tired front door for one that is warmer and more secure.

Homes in Daventry
Older buildings in Daventry’s town centre usually look best with flush casements or sash-style windows in a heritage colour, paired with a traditional panelled front door. The 1960s and 1970s homes that make up much of the town suit simple A-rated casements in white or anthracite grey, and a composite front door, which we supply and fit with Ultion 11-pin locks, adds warmth and security. On newer estates, the safest choice is usually to match the builder’s original frame style and colour so the street stays consistent. Across all ages of home, many owners replace an old patio door with French doors, aluminium bifolds or a sliding door to make more of the garden.
Windows and doors in Daventry: your questions answered
Do you cover Daventry?
Yes. Daventry is about 24 miles from our factory and showroom on Saffron Lane in Leicester, and our own installers fit windows and doors across the NN11 area, including Braunston and Long Buckby. You can visit the showroom to see frames, colours and doors, or we can come to your home to survey and measure. Call 0116 283 1010 to book.
Do I need permission for new windows in Daventry town centre?
Possibly. The historic core, including High Street and Sheaf Street, is a conservation area with many listed buildings. Like-for-like replacement on a house is usually permitted development, but the rules can be tighter in a conservation area and listed buildings need consent. West Northamptonshire Council, which took over planning from Daventry District Council in 2021, can confirm what applies.
Is it worth replacing windows in a 1970s Daventry house?
If the frames have misted units, draughts or locks that no longer work well, new A-rated casements can make the house warmer and quieter. Outside the conservation area, like-for-like replacement on a house usually does not need planning permission, so it is normally a simple job. It is still worth checking your deeds for any covenants about the outside of the house.
I live in a flat in Daventry. Can I get new windows?
Check first. Flats do not have the same permitted development rights as houses, and the windows often belong to the freeholder, so read your lease and speak to the managing agent. If the building is in the conservation area or the new windows would look different, ask West Northamptonshire Council before ordering. As we are FENSA approved, you get a Building Regulations certificate.
