Quality UPVC Windows and Doors, Fitted to Last
— About this service
Whether you're replacing tired old frames or upgrading to double glazing for the first time, UPVC windows and doors are one of the best investments you can make in your home. At Ray Sarll Renovations, we've been fitting UPVC windows across North London for over 25 years, helping homeowners reduce energy bills, cut outside noise, and improve kerb appeal. We work with trusted suppliers to source high-quality frames in a wide range of styles and finishes — from classic white casement windows to modern anthracite grey designs — and our experienced team handles everything from the initial survey through to final installation with minimal disruption to your day.
— Our Process
We visit your property to assess your existing windows and doors, discuss what you need, and provide a clear, no-obligation quote with no hidden costs.
Your UPVC windows and doors are made to measure for your property, ensuring a perfect seal, a professional finish, and maximum thermal performance.
Our skilled fitters remove your old frames cleanly and install the new windows to the highest standard, leaving your home tidy and fully weather-tight the same day.
— Benefits
We've been fitting UPVC windows and doors in London homes for decades. You get the benefit of that expertise on every job, however large or small.
All our installations comply with current building regulations and we carry full public liability insurance for your complete peace of mind.
Our team protects your floors, removes all old frames and waste, and leaves the site spotless before we go.
UPVC windows and doors offer a level of thermal efficiency that older timber or aluminium frames simply can't match. Modern double-glazed UPVC units dramatically reduce heat loss, meaning lower heating bills and a more comfortable home all year round. The frames are also virtually maintenance-free — no painting, no warping, no rotting — making them a genuinely smart long-term investment.
We work with homeowners across Finchley, Hendon, Mill Hill, West Hampstead, and the surrounding areas, fitting everything from single window replacements to whole-house installations. Every job is treated with the same level of care regardless of size, and we're always happy to advise on the right style and specification for your property and budget.
— FAQ
Most single or double replacements are completed within a day. A full-house installation typically takes two to three days depending on the number of windows and access requirements.
