UPVC Window Installers in Market Deeping

Really happy with how the new windows look and feel. Much better than what we had before.

From start to finish, the team at Composite Doors were a pleasure to deal with. We replaced all our old windows with new A++ uPVC frames and the results are amazing.

Jason installed everything himself—on time, no fuss, and completely professional. The house is warmer, quieter, and looks great from the outside. We went for anthracite grey which really modernised the place. Everything now shuts tightly and opens easily. We’ve already recommended them to two other families on our street.

Just had all the windows done in our semi-detached and we’re already feeling the benefits. No draughts, no sticking frames, and they look fantastic.

Jay made sure everything was fitted properly and cleaned up after himself. Composite Doors delivered on everything they promised. It’s been a stress-free, worthwhile investment.

We replaced every single window in our home with uPVC units and the difference is staggering. Composite Doors were fantastic throughout—gave good advice, didn’t oversell, and stuck to the price.

Jason turned up right on time, worked carefully and respectfully, and left no mess. We’ve got far fewer cold spots, it’s much quieter indoors, and the house feels completely modernised. Very pleased with the outcome.

Composite Doors fitted nine new uPVC windows for us over two days. Jay worked with precision and didn’t cut corners.

Each frame is perfectly aligned, and the sealing is flawless. The windows open smoothly, keep the heat in, and the noise out. We’ve had loads of compliments on the new grey frames. Great product, great service, and everything was done right first time.

We’ve had every window replaced by Composite Doors and I honestly can’t believe how much better the house feels. It’s quieter, warmer, and looks far more modern.

No more rattling windows when it’s windy! The new ones seal tightly and look fantastic.
