Is Your Old Door Letting in the Cold? Time for a uPVC Upgrade
If your door feels draughty, doesn’t close properly, or just looks tired, it’s more than an inconvenience, it’s costing you money and comfort. Old doors are often a major source of heat loss and poor security.
Whether glazed or solid, a high-quality uPVC door offers a reliable, low-maintenance solution that’s built to perform. From front and back doors to patios and porches, a well-fitted energy-efficient uPVC door makes a noticeable difference.
An Affordable, High-Performance Door Built to Last
uPVC doors are one of the most popular choices for homeowners and for good reason. They’re durable, weather-resistant, and far more cost-effective than timber or aluminium.
Even without glazing, they offer excellent thermal insulation thanks to multi-chambered internal structures, reinforced panels and modern sealing techniques. And if you're looking for something with glass, we offer a range of uPVC doors with double glazing—perfect for patios, French doors, and stylish front entrances with decorative panels.

FAQs – uPVC Doors: What to Know Before You Buy
Are uPVC doors always double glazed?
Not always. Many styles, like solid front doors or stable doors, don’t contain glass at all. However, we do offer uPVC doors with double glazing for French doors, back doors with windows, and glazed panel options.
Will a uPVC door help reduce heat loss?
Yes. Even without glass, the multi-chambered uPVC frame and tight seals help keep heat in and cold out, improving your home’s energy efficiency.
Can I choose a door without any glazing?
Absolutely. We install fully solid uPVC doors as well as part-glazed and fully glazed designs—depending on your needs and style preferences.
What styles of uPVC doors do you offer?
We fit a wide range including solid and glazed front doors, French and patio doors, stable doors, and doors with decorative sidelights.
How long will my new uPVC door last?
Properly installed uPVC doors typically last 20–30 years or more with minimal maintenance.
Is the installation disruptive?
Not at all. Most doors are installed in a single visit, and we leave your property clean, tidy, and fully secure.
Do you offer guarantees?
Yes, every door comes with a 10-year product guarantee and a 12-month workmanship warranty.

We live in a windy area, and our old door just wasn’t up to the job. Since we had a new uPVC one fitted by Composite Doors, the difference has been huge.
No draughts, no rattles, and it looks really smart too. Jay was efficient, tidy, and checked everything was working properly before he left.

We wanted something maintenance-free but still stylish. This new uPVC stable door ticks all the boxes.
Easy to use and great for letting air in without opening it fully.

We chose a uPVC front door in Anthracite Grey to replace our old, warped timber one, and the result is amazing. It looks contemporary but still suits the house.
Composite Doors were excellent throughout – clear pricing, friendly service, and no pressure. Jason’s installation was flawless, and the house is already feeling warmer and quieter. We’ve had loads of compliments on the new look. Highly recommend them.

We’ve just had a double-glazed uPVC stable door installed in the kitchen and it’s brilliant. The top half lets air through while the bottom stays secure – ideal when cooking or letting the dog out.
Composite Doors made it really easy from start to finish. Jay was friendly and professional, and the installation was quick, clean, and surprisingly quiet. A huge improvement overall.

We went with a custom uPVC front door and sidelight, and it’s completely transformed the front of our home. Composite Doors helped us with the design and Jay installed it with care and precision.
The locking system feels solid and the hall is warmer than it’s ever been. Great service, great result.

Just had a new uPVC door fitted by Composite Doors and I’m genuinely impressed. The colour we chose (Chartwell Green) gives the front of our house real character.
Jay did a great job – careful, clean, and professional from the moment he arrived. No more cold draughts, stiff locks, or rattling in the wind. It’s been a worthwhile investment and we’re considering them for new windows too.

Had a grey wood-effect uPVC front door installed recently and it’s a total game changer. The house feels warmer and quieter and it looks incredibly smart from the street.
Jay explained everything clearly, turned up on time, and left everything spotless. Great job by Composite Doors – professional from start to finish.

We had a glazed uPVC patio door installed last month, and it’s completely changed how we use the back of the house. It opens effortlessly and shuts tight with no cold coming through.
The double glazing really does its job. Composite Doors were great to deal with – they explained all the options clearly, gave us time to decide, and Jason fitted everything professionally. We now spend more time in the back room thanks to the light and comfort.

We weren’t sure about uPVC at first, but Composite Doors really changed our minds. The door is beautiful, well-built, and perfectly colour-matched to the rest of our windows.
Jason was very knowledgeable and worked efficiently. The whole process was hassle-free, and now our entrance looks so much better than before. Really pleased with how it all turned out.

Can’t believe how much warmer our kitchen is since having the new uPVC door fitted. Jay did a great job from start to finish – measured everything properly, cleaned up after himself, and explained how to care for the door.
The finish is excellent, and the locking mechanism feels really secure. Composite Doors were helpful with colour choices and glazing options. We’re already thinking of upgrading the front door next.

We recently had Composite Doors replace our worn-out back door with a new white uPVC one, and the difference is unbelievable. The room used to feel cold even with the heating on, but now it stays warm all day.
Jason was punctual and professional, clearly took pride in his work, and made sure the job was done to a high standard. The new door is well-finished, locks securely, and feels really sturdy. Very happy overall.

Jason fitted our new solid front door and we’re really happy with it. You can feel how solid it is and it seals shut tight.
Feels much more secure, especially with the updated locking system.
