Ryan Flynn

Superb company. Highly recommend them. Proper engineers for design and fitting. We changed spec due to some building changes and they were clear and responsive to queries and redesign. Really trustworthy group of people from sales to design to fitting. I would use them again without hesitation. Warm regards Daniel

Daniel Champman

The team delivered great sliding doors at a more competitive price than other suppliers. They responded to our changing development schedule without making it an issue and have provided great aftercare as well.

Daniel

We had been severely let down by a previous supplier, but when we turned to Direct Trade Windows for help, we hit the jackpot. Helping us to transform a residential development in Hersham, they supplied us with high-quality, ultra-slim Cortizo sliding doors, complete with the bespoke sliding options that we needed. Our requirements were very specific and not readily available on the market, but Direct Trade Windows really went the extra mile to help us out, coming through with quality products and excellent service. We will definitely be using their services again.

Park Lane Developments

Nothing but praise for this outfit. It was a pleasure to work with them. It was a nerve-wracking undertaking for us, the biggest single expense to fit three large window/french door combos in our extension, yet the team made it a relatively relaxing experience with their professionalism and good humour. Thank you all so much for everything you and the whole team have done to get from the initial sale (well done Hash!) to the fun visit we made to the workshop, to the design and its multiple iterations (thank you Taz!) and finally to the installation. Thoroughly recommended.
