Honest words from people who've had us round
"Replaced every window in our 1930s semi. The team turned up when they said they would, finished a day early, and left the place spotless. The house is unrecognisable — and so much warmer."

"We had 5 quotes for our bifolds. Nailsea wasn't the cheapest, but you could tell straight away they actually knew what they were talking about. Three years on, they still slide like silk."

"Conservatory build took 9 days from start to finish. Beautifully done — proper craftsmen. The lead fitter has been there 22 years and it absolutely shows."

Our story

Three generations. One workshop. Zero shortcuts.

Nailsea Windows opened its first workshop in 1978 — the same year Star Wars came out, and a few months before Margaret Thatcher took office.

What started as one fitter and a Transit van has quietly grown into one of the West Country's most trusted installation specialists. We've never been the biggest — we've always taken pride in every job. And 90% of our business still comes through word-of-mouth recommendations. Almost unheard of in this trade these days.
