A service you can rely on

"Cannot fault customer service in anyway from this firm we called in reference to get a quote to replace some windows. Nick came out the same day was very helpful with ideas and suggestions of what types of windows that would suit and with 24 hrs a quotation was waiting in my inbox. We shall be almost certainly be putting an order in shortly. Cannot recommend this company more highly to anyone thinking of new windows or doors should definitely give Nick a call."

"Brilliant local company. Installed a new door for my father (after a recommendation by a friend). Great product, great price, but (& I can not stress this enough) their kindness & care dealing with an elderly gent, especially regarding the guarantee (so both myself as his son & he could have a copy) was amazing. I genuinely did not believe service like this existed any more. Lovely people to do business with & a company I can thoroughly recommend."

"Through a recommendation, I popped into the office to see if they could help me source a new door handle. Nick was extremely helpful and ordered one for me through a company they use. I will certainly recommend the company to family and friends and I will use them for replacement windows and doors in the future. Many thanks for the free tin of silicone spray!"
