Enhance your home’s performance by upgrading your windows

Known for their clean, symmetrical appearance and slender sightlines, aluminium casements enhance any Exeter and East Devon property with light whilst never compromising on style. But, as they’re loaded with security features and the latest thermal technology, they’re highly valued by homeowners for much more than their good looks. Thanks to non-corrosive, robust aluminium and a fully weatherproof design, they’ll keep your home draught and weather-free for years to come too.

Choose from RAUM and Alitherm aluminium casements, top and side hung variations, multiple sizes and colours. With so much choice, we make it easy to find an aluminium casement window that looks and performs exactly how you want it to. Choose from double or triple glazing too, which comes expertly fitted by our adept installation team for long-lasting quality.

"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."

"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!"

"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."

- Ashley D. 5

"Excellent delivery of service and installation (11 windows and 1 door). Thank you Tom for a job well done! Clean and very efficient. We were recommended by word of mouth to use Doors and Windows and would not hesitate to recommend this company ourselves. Many thanks."
