Conservation-area stone and brick along the old Watling Street need careful scaffold and material-matching. The Tove valley funnels damp air; roadside frontages limit pavement scaffold space.
We cover Watling Street, Brackley Road and the wider NN12 area, and price every velux & skylights job against the specific stock and access on your street — not a one-size guess.
Most Towcester homeowners who call us about velux & skylights have noticed a dark loft room or landing you want to light. The way we approach it depends on your property and street. Conservation-area stone and brick along the old Watling Street need careful scaffold and material-matching. That local reality — the stock era, the access, and the tove valley funnels damp air; roadside frontages limit pavement scaffold space — is exactly what we price against, rather than a one-size national rate.
Done properly, locally. Rooflights are set with the correct flashing kit for your covering so they stay watertight for good. Workmanship is guaranteed for 10 years; Velux units carry their own manufacturer warranty.

We cover Watling Street, Brackley Road and the surrounding roads, and we are happy for you to get other quotes: a proper roofer expects it.
