Sash windows for Colindale homes
Around Colindale you will mostly find 1930s semis, newer apartment blocks and the Grahame Park estate. Some 1920s houses have sash windows alongside bays, so note whether the bay sashes slide or are fixed before deciding how closely to match the original arrangement.
Newer homes built in a traditional style sometimes have mock sashes, and genuine sliding sashes can replace them where you want a more authentic opening action. In mansion blocks, sash replacement is often controlled by the freeholder or managing agent, so get written approval of the glazing pattern and material before ordering.
With the M1, the A5 Edgware Road and the Northern line all close by, traffic and train noise affect many homes, and acoustic glass helps. Barnet Council covers the area. Our Edmonton factory is about 9 miles away via the North Circular.
Sliding sash windows open vertically and give period homes their familiar look, with balanced sashes, horns and glazing bars. We make replacement sash windows to match original proportions, suiting owners of Victorian, Edwardian and Georgian properties who want better insulation and security without losing traditional character.
- Traditional look with modern weather sealing
- Matched to original proportions and glazing bars
- Smooth vertical sliding operation
Questions from Colindale
Do I need planning permission for sash windows in Colindale?
Most house replacements in Colindale need no permission, but flats in new developments usually need freeholder or management company consent first, which we help arrange. Replacement sash windows on a house are usually permitted development if they look similar, with FENSA covering Building Regulations, but conservation areas with Article 4 directions, listed buildings and flats often need consent.
How soon can you fit sash windows in Colindale?
Lead times vary by product and workload — confirmed with your quote. Being about 9.0 miles from our factory makes surveys, fitting days and aftercare visits easy to arrange.
Will replacement sash windows look the same as my originals?
We match the proportions, glazing bar layout and features such as horns as closely as possible. Modern sashes hold thicker double glazed units and weather seals, so sightlines can differ slightly from slim single-glazed originals, which is worth seeing in person before you decide.
Can I see samples before I decide?
Yes. Our showroom is at Unit G, 1 Anthony Way, London N18 3QT (Mon–Fri 8am–5pm), about 9.0 miles from Colindale. We can also bring samples to your home in Colindale at the free survey.
