Steve and Jenny Welsh
We received a text, within the period advised by the surveyor, asking us when would be a convenient time for the installation.
On the day of the installation the first fitter arrived early in the morning and started removing the old windows and doors. Soon after a second van arrived with the replacement doors and windows and installation commenced. The men worked non stop and completed mid-afternoon. The surrounds of doors and windows were repaired where necessary. The old fittings were removed and all the rubbish swept up and cleared away.
We were shown how the locks and the internal blinds worked.
Overall we are very satisfied with the new doors and windows and the workmanship of the fitters. We would certainly recommend Ruislip Windows and Doors Ltd to anyone.

1986
Humble Beginnings and Foundation
1995
Expanding Expertise and a New Identity
As demand grew, so did the company’s ambitions. By the mid-1990s, new double glazing systems were introduced and the contracts grew with the demand. To reflect the evolving nature of the business, Ruislip Building Ltd rebranded to Ruislip Windows and Doors Ltd in May 1995. This move showcased a transition into the specialist field we now thrive in.
2000
Building Trust and Industry Recognition
The early 2000s marked a decade of consolidation and trust-building. With over 15 years of experience by this point, the company was no longer a small local firm but a recognised company in the area.
The team’s customer-first approach made Ruislip Windows and Doors Ltd a go-to name for premium double-glazed installations, trusted not only by homeowners but also by commercial property managers.
2020
Relocation and Team Expansion to Support Growing Demand
2023
Becoming a Family-Run Business with the Next Generation Onboard
In 2023, Ruislip Windows and Doors proudly became a family-run business as Joe, the son of owner John, officially joined the team. By keeping business within the family, Ruislip Windows can now continue to uphold the same values that have made them such a trusted name over the last 40 years.
2025
Expansion into a Larger Office with an 11-Van Fleet on the Road
In 2025, we expanded once again, moving into a larger commercial unit in Dwight Road, Watford. Giving us more space, and an improved showroom, to support our growing operations. With a fleet of 11 vans now on the road, we’re better equipped than ever to serve our customers across the region.
