What is the difference between uPVC and composite doors?

uPVC doors are cost effective and low maintenance. Composite doors use a dense core and tough skin for added strength, security, and a premium feel.

Are your doors energy efficient?

Yes. Doors are A+ rated with quality seals and glazing to reduce draughts and improve comfort.

How long does door installation take?

Most single doors are fitted within a few hours, including removal of the old door and tidy up.

Can I choose colours and hardware?

Yes. Pick from classic or contemporary colours, woodgrains, handles, letterplates, knockers, and glazing options.

How secure are your doors?

Doors include multi point locking, robust hinges, and quality cylinders for strong protection.

Do your doors come with a guarantee?

Yes. You get a 10 year guarantee on the door and our installation.

What customers say about this service

Tommy replaced all the windows and doors in our house. Our upstairs windows were actually illegal as we wouldn't have been able to get out of them during an emergency. I was very worried because of this and Tommy kindly booked us in asap. Unbelievably he replaced our front door, patio doors, back door, garage door and all the windows in one weekend for an extremely reasonable price. We left Tommy our keys and went away for the weekend and returned to a transformed house! He did an amazing job. All the windows are so neat. The front door is superb and totally draft free. Tommy also cleaned and hoovered up after himself and left the house spotless. Two years on and we're still so happy with the work Tommy did. I couldn't recommend him enough.

Outstanding work from Tommy – couldn't be happier! Tommy recently fitted new door windows and soffits for us, and we are absolutely thrilled with the results. From start to finish, his work was professional, precise, and carried out with genuine care and attention to detail. He turned up exactly when he said he would, worked efficiently, and kept everything incredibly tidy – not always a given with building work! The finish on both the windows and the soffits is immaculate. You can tell Tommy takes real pride in his craft, and it shows in the quality of the final result. He also took the time to explain each stage of the process clearly, which gave us a lot of confidence. Nothing was rushed, and he clearly knows his trade inside and out. The transformation to our home is brilliant – it looks smarter, feels more secure, and we've already had compliments from neighbours. Highly recommended to anyone looking for skilled, reliable, and friendly service. Thanks again, Tommy – you've done a fantastic job!

I had all of my windows and a door replaced by Tommy's Windows. From the first phone call Tommy was easy to communicate with, and was throughout. The quote was fair, the work was carried out rapidly and to a high standard, and they left me with next to nothing to tidy up after they had finished. All in all a great job was done. So yes I would recommend.
