Renfrewshire Windows And Doors is a local company supplying and fitting windows, doors, and conservatories across Renfrewshire and the surrounding areas. If your home needs new double glazing, a solid front door, or a set of patio doors that actually keep the heat in, we can sort it for you properly.
We are not a call centre or a national chain. You deal with real people, get straight answers, and we come out to measure up and give you a proper quote with no pressure attached.
What windows and doors do you offer?
Our range covers most of what homeowners in this area ask for. uPVC windows are the most popular choice, built to last and easy to keep clean. For doors, we fit composite front doors, uPVC doors, French doors, patio doors, and stable doors depending on what suits your property.
We also supply and install conservatories and fit triple glazing for customers who want the extra performance in colder or noisier locations. Every product we fit carries an A energy rating as standard, which keeps your heating bills in check and your home more comfortable through the winter.

How secure are your products?
Security matters, especially on ground floor windows and external doors. The composite doors we fit include multi-point locking systems as standard, along with reinforced frames and solid cores that make them significantly harder to force than an older timber or basic uPVC door.
Our uPVC windows come with shootbolt locking hardware and toughened or laminated glass options. If you have specific concerns about a particular window or door on your property, mention it when we come out and we will advise on the right specification for that opening.
How long does fitting take?
From the point of ordering, we aim to have your installation completed within ten weeks. For most jobs, the fitting itself takes one to two days depending on how many windows and doors are involved. We keep you informed at every stage so you know exactly when to expect us.
Our fitters are experienced, tidy, and will leave your home clean when they go. Any mess made during the fit gets cleared before we leave. It is that simple.
What guarantee do I get?
All products we supply and install come with a full ten year guarantee. That covers the frames, the glass units, the hardware, and the installation itself. If something is not right within that period, contact us and we will deal with it.
We are fully insured and all our work meets current building regulations. You will get the relevant paperwork when the job is done, which is useful if you ever come to sell your home.
Do you offer free quotes?
Yes, all quotes are free and there is no obligation to go ahead. We come out to your property, take accurate measurements, talk through your options, and give you a clear written price. There is no hard sell and no one chasing you afterwards if you want time to think it over.
Prices vary depending on the products chosen, the number of windows and doors, and the specifics of your property. The only way to get an accurate figure is to have someone come and look, which is what we do.
Why do local homeowners choose Renfrewshire Windows And Doors?
Customers come back to us and recommend us to their neighbours because we are straightforward to deal with. Renfrewshire is our patch. Our reputation here matters to us in a way it simply does not for a company operating nationally with thousands of customers across the country.
Every job gets the same attention regardless of its size. A single front door gets the same care as a whole house refit. Our five star reviews reflect that consistency, and we would rather earn your trust than promise you things we cannot deliver.
