I had a great experience using Alpha. From being patient and helpful whilst I made my choices to the great end result. I had new windows from them some months back and did not hesitate to go back for the addition of new doors. Staff are always courteous, very professional and friendly and update you throughout. I am really pleased with the new look and would definitely recommend Alpha.

We needed a new front door with side panel and a new garage door and window. We looked at a number of designs and options and Alpha Windows were very patient and helpful in getting us to a final design and specification which we are very pleased with. Alpha Windows were very clear about the payment schedule and the timescales for delivery and installed the doors and windows on the agreed date. The installer was easy to work with and completed the work to a high standard.

I used Alpha Windows to supply and fit an external back door. They were extremely professional from the first communication. They exceeded expectations by being able to install the door much earlier than I had expected. They were flexible with dates/times I could be available. The installer was extremely thorough, professional and very tidy too.

Very pleased with Alpha Windows who were recommended to me by several people. The products are excellent and the fitters were very efficient and clean and tidy - minimum mess! They were also extremely helpful in putting back my blinds and curtains. Cannot recommend them highly enough.

I used Alpha Windows a few years ago to install doors and windows in my previous house, I was very pleased with the service and have just used the company again to fit composite front and back doors plus French windows in my present home. I received a great deal of help from Alpha regarding my requirements and they also contacted me after the designs were completed to offer further useful suggestions, nothing was too much trouble. The installation went smoothly and the order was completed within the timescale I was originally given.

I had a balcony door replaced and a balcony refitted. Everything was done to my satisfaction and if not more. The workers were very friendly and left the place in a very tidy fashion. The Door itself far exceeded my expectations and I requested an alternative handle to one previously agreed the day before installation which was communicated swiftly as I was pleasantly surprised with an even better alternative. I must commend their customer service as due to staff illnesses the installation was cancelled a few times so they decided to take some money off the original price for inconvenience purposes. Thank you so much. I would recommend to everyone.
