Services
Windows
Our A-rated uPVC windows combine energy efficiency with security, featuring low-E glass to reduce heat loss and enhance insulation. Available in sculptured, chamfered, or flush designs, they offer customisation with Georgian bars, textured frames, and dual-colour options. Backed by a 10-year guarantee, they ensure long-term durability and aesthetic appeal.
Doors
Secure and stylish composite doors include options like Solidor and Magnum models, featuring Ultion locks for advanced security. Available in modern uPVC or aluminium finishes, they provide thermal efficiency and weather resistance. Customisable with glass panels and finishes, they enhance kerb appeal while meeting PAS 24 standards for safety.
Living Spaces
Transform your home with bespoke conservatories, orangeries, and glass extensions. Choose from glass, tiled, or lantern roofs to optimise light and temperature control. Designed for year-round use, these spaces integrate seamlessly with your home, offering energy-efficient solutions for dining, relaxation, or work areas.
Roofline
Durable fascias, soffits, and guttering protect against weather damage while improving your home's appearance. Modern materials ensure low maintenance and longevity, with custom colours to match your property. Upgrades include ventilation solutions to prevent condensation and maintain structural integrity.
Glass
A-rated low-E glass enhances energy efficiency, while obscure, toughened, and laminated options provide privacy and safety. Solar control glass reduces heat gain, and acoustic glass minimises noise. Custom leaded designs add traditional charm to windows in period properties.

After much research i selected Alpha to fit double glazing throughout our house - mixture of new Windows and replacing all glazing in existing conservatory. I found them to be competitive along with the all important FENSA accreditation and insurance backed warranty (cheaper local companies didn't offer this)
Install was good, the installers identified two damaged units during the installation and replaced both a few weeks later without hassle
Overall very pleased with the friendly and convenient service received

I would not use Alpha Windows again if you paid me. They installed my upstairs windows a few years back and did an excellent job so I decided to use them again. This was a huge mistake! The first door turned up damaged so had to be returned. The fitting was appalling so we had someone out to check the work who agreed it was sub standard. Several weeks later second door arrived with no glass. Waited a few more weeks and the door turned up all ok! Now 11 months on the lock will not work - called Alpha Windows on Saturday who refused to take my details over the phone so I had to log it on line. I

An all round great service and friendly staff. I've used Alpha twice now and both times they have fitted my windows to the highest standards. Any issues during or after installation were dealt with in a timely manner (sometimes on the same same day) and nothing ever felt too much to ask, as long you make good tea :) I would highly recommend Alpha Windows!

Having had a quotation, we wanted to see the type of window that was suggested for our older house. Small range of windows in the shop, knowledgeably explained. Polite and competent.
