Why homeowners choose Roundhay Windows And Doors
A family name on every job
We are a third-generation family business. One of the family looks after your enquiry and keeps an eye on your installation from start to finish.
More than three decades of know-how
Our family has been making and installing windows and doors for over 30 years, so we have seen every kind of opening, bay and awkward corner.
Built in our own workshop
We make your frames to measure ourselves instead of buying them in, so we can check the quality of every joint, seal and lock.
Our fitters, nobody else's
The people who arrive at your door work for us. We never hand your installation to a subcontractor.
15 years of cover, in writing
Every installation comes with our written 15-year guarantee. Read what it covers.
A free survey and a firm price
We visit, measure and talk through the options, then give you a fixed written quote. No hard sell, and no obligation.
Common questions
Are aluminium windows warm enough for a Yorkshire winter?
Yes. Modern thermally broken frames with energy-saving glass keep the heat in and help prevent condensation.
How big can an aluminium window be?
Fixed frames go up to 7 m² in the Premium range and 4.8 m² in Slimline.
