Services
UPVC Windows
Our UPVC windows combine thermal efficiency with durable construction, featuring multi-chambered profiles for enhanced insulation. Available in modern and traditional designs, they meet current energy ratings while maintaining aesthetic appeal. The internally beaded frames provide additional security against forced entry.
Composite Doors
Engineered for maximum security, our composite doors feature reinforced frames and advanced locking systems while maintaining traditional timber aesthetics. The thermally efficient construction reduces heat loss and requires minimal maintenance. Available with optional Georgian bars and decorative glass elements.
Aluminium Windows
Slimline aluminium windows offer contemporary styling with exceptional strength-to-weight ratios. Their corrosion-resistant properties ensure longevity, while thermal break technology maintains energy efficiency. Customisable in various RAL colours to match property specifications.
Bifold Doors
Aluminium bifold doors create seamless transitions between indoor and outdoor spaces with minimal sightlines. The multi-point locking system ensures security while the thermally broken frames maintain energy performance. Available in configurations with up to seven panels.
Conservatory Roofs
Our insulated solid roofs transform conservatories into year-round living spaces with improved thermal regulation. The composite construction reduces solar glare while maintaining natural light transmission. Internally, the ceilings require no additional decoration and integrate with existing property architecture.

Ada replaced all of my windows and front and back doors. The actual lead time was much shorter than expected - they came and installed the windows about a week after I ordered. The doors were made to measure so they came back to do them maybe 3 weeks later. They did a great, fast job installing - would recommend to anyone.

We had a double glazed UPVC window fitted in our office room today and we are so pleased. The guys did a quick and thorough job with the least amount of mess. The whole process from speaking to Ali to arrange it all, to surveyor and installers ran so smoothly. Cannot rate this company enough. We will definitely use them again.

Aysegul was fantastic and arranged for Oktay and Hakan to come next morning. They gave a very competitive quote. I stressed the urgency and within a couple of days Ali called from the factory to say the units could be fitted after the weekend. Good as their word, Mr Niyazi, Mr Angel and Mr Akyol fitted the units without a hitch or mess. They also fitted replacement hinges to another window. Next morning they dropped in to ensure everything was OK We are so lucky to have Ada windows locally- a big thank you to the team who I could not recommend more highly. Paul Zickel - Wood Green

I've used ADA windows twice and both times the guys were quick, clean and polite. I also think the prices were reasonable. I honestly don't have any complaints and I would definitely use the service again.

I was extremely happy with the work of the ADA team! The quality of the windows was beyond my expectations and the workmanship of the team was very professional, resulting in an overall high quality end result! I love my new windows. Thanks to the hard-working team and the high value of the product/service! I would definitely contract ADA again and recommend them to anyone.
