Expert installations with no pushy salespeople and no hidden costs. FENSA registered, fully insured, and trusted by homeowners since 2003.
The Alpha Windows difference
New windows and doors are a long-term investment. We treat them that way.
Most glazing companies want you to decide quickly. They'll visit your home, sit at your kitchen table, and won't leave until you've signed something. We've never worked like that and we never will. When we visit, we take the time to properly understand your home, your priorities, and your budget — and if you need time to think, we'll give it to you.

We were very happy with the service we received. We understand the delays were out of your control. The guys who came to fit the windows were really nice and efficient. Joe has been lovely from start to finish on this job! Alpha Windows has given us the best level service from all the window companies that we spoke to. The other companies had poor service and one of them was quite rude. So overall, we can't complain and are happy we went with Alpha windows!

It has been a total pleasure to work with you all over the last couple of months. Since the drama with Ridgwell we were worried about trusting another company but from the first contact with you via phone and seeing you face to face in the showroom we were put at ease. You were so friendly and listened to our needs and worries and helped us chose what was right for us.

From the initial engagement right through to the installation, Alpha Windows have been outstanding. Every question I had was answered promptly and clearly, and they were extremely helpful in accommodating my requested design. The pricing was very competitive, and the final product exceeded my expectations — the door and surrounds are absolutely beautiful.
