UPVC Window Installers in Thorne
Tired of Cold Drafts, High Bills, and Tired-Looking Windows?
Old, single-glazed or poorly fitted windows are more than just unsightly, they’re one of the biggest causes of heat loss, draughts, condensation, and sky-high energy bills. They can also let in unwanted noise, stick when opening, and ruin the look of your home from the outside.
That’s why so many homeowners are switching to modern uPVC double glazing. Built for insulation, noise reduction and durability, it’s the smart way to improve comfort, reduce heating costs, and instantly update your home’s appearance.
A Simple, Long-Lasting Solution That Works
uPVC windows are designed to solve the problems traditional frames can’t. Made from weather-resistant, low-maintenance materials, they won’t warp, peel or rot, no matter how tough the weather gets.
Our A++ rated glazing options dramatically improve thermal performance, helping to keep warmth in and cold out. Triple glazing is also available for homes in noisier or colder areas, adding an extra layer of protection and peace of mind.

Built Around Your Style, Not Just Performance
You don’t have to sacrifice looks for practicality. With today’s advanced finishes, uPVC windows come in a wide range of colours and styles to suit any home, from clean modern lines to traditional timber-look designs.
Popular colour options include white, cream, black, grey, brown, and a choice of woodgrain finishes. Want something specific? We also offer RAL colour matching to blend perfectly with your existing home or front door.

The old wooden windows were painted shut and full of gaps. The new uPVC ones have changed everything—clean lines, secure locks, and no more drafts.
Jason from Composite Doors made it look easy. He worked methodically and double-checked everything. The installation was clean, fast, and the house feels like it’s been updated overnight.

We replaced 10 windows with Composite Doors and went with cream uPVC to match the extension. Jason arrived on time, fitted everything quickly, and the finish is immaculate.
No more draughts or condensation. The new units glide open and seal tightly. The whole house feels warmer and more peaceful. Best investment we’ve made in years.

The new uPVC windows from Composite Doors look brilliant and have massively improved the temperature in every room. Jason was polite, professional, and explained everything as he went.
The install was finished faster than expected, and the quality is excellent. The woodgrain finish we chose works perfectly with the house. Worth every penny and we’d use them again in future.

Jason fitted them with care and precision. Everything opens smoothly now, and we’re already noticing fewer draughts and much less condensation on the glass.

We live in a semi-rural area and wanted something that looked traditional but performed better. Composite Doors helped us choose the right wood-effect uPVC windows and they look fantastic.
Jason was friendly and worked efficiently, keeping the house tidy throughout. It’s much warmer, and the house feels refreshed without losing its character. I’ve already recommended them to my neighbour.
