I’ve just had all my windows and doors replaced by Ash and Ivan at Window Wise, Haywards Heath. They have done a lovely job. They were efficient, timely, considerate (they cleared up after themselves every day), cheerful and their work was faultless. And a special mention to Gavin who sold me the product - he was knowledgeable , enthusiastic, courteous without a hint of the hard sell. All in all I’m very very pleased with my house facelift!

We recently had Window Wise to change our old conservatory to a pitched roof and higher specification glass. Results are encouraging in controlling the internal temperature. The team of Nick, Ollie and Adam were extremely professional craftsmen and were a pleasure to have at our house. It was not a simple construction with complicated flashing and tile hanging to revise. All the work was undertaken to the highest standard and we are extremely pleased with the result.

We have just had a new front door fitted with window wise and had a wonderful experience from start to finish. The sales team were wonderful and thorough and patient with my endless questions, and the surveyor and fitters were all very polite and friendly as well as efficient. Plus our door ended up being manufactured in half the estimated time so we were able to start enjoying our new door far quicker than expected, what a bonus! If we ever decide to replace all our windows too I know who I’ll be contacting!

An excellent job, very pleased with our new bedroom window and cupboard door. Very polite, Ollie and Adam worked very hard in 26 degree heat. We have used Window wise many times over the years and will definitely use them again. Highly recommend them.

I recently contacted WindowWise concerning an issue with the rubber seals on our 5 year old bi-fold doors. John, their Aftersales Service Engineer, responded promptly and the issue was resolved quickly and efficiently. John was extremely professional in every way. A Five Star after sales service.
