Testimonals

"I have nothing but praise for Costessey Windows! They have just replaced the front door and all windows on our bungalow. From the quotation through to fitting our experience was nothing but professional. Mark provided really helpful advice when we were deciding what we wanted. He was always on time and communication was excellent. Ably assisted by Tim, the fitting went smoothly. The windows and door look fantastic! We are so pleased with them. In particular Mark has attention to detail which ensures the finish is excellent. Also very clean and tidy workers which was much appreciated! The price was competitive too. I have no hesitation in recommending Costessey Windows." Mr and Mrs Vince, August 2024

"Costessey windows and doors were recommended to us by a friend who was very pleased with her new windows. The service we have received from Mark and the team has truly been exceptional from start to finish. Great care and attention was taken in the fitting of the doors and windows, they were always on time, extremely tidy, and the product they offer is superb. We replaced all the existing upvc windows and doors in our house, and the difference it has made is outstanding. We have recommended this company to friends and family and would urge anyone considering new doors or windows to speak to this company as I really doubt you will do better. I cannot praise them enough." Mr Death, June 2024

"Mark and his team have done a first class job replacing my windows, front door and French doors. From the first appointment where he was punctual, professional and took meticulous measurements Mark’s attention to detail was obvious. With Helen keeping me updated and providing a quote and start date that were very competitive (and so quick!) it wasn’t long before fitting day. Mark and Tim have years of experience and they were precise, tidy and very considerate. They also took me through the features of the new doors and windows and gave me great advice from placement through to safety features. The entire experience was a delight from start to finish. Mark and his team are fantastic at their job and their craftsmanship and attention to detail are incredible! 5 golden stars for this outstanding team!" Freudian, February 2024
