Superb conservatory
Customer Service
My husband and I are so pleased with our conservatory which has added to our house so much. It has gone well beyond our expectations. From planning with Jason and Sean to the other builders Paul, Alex, Sash, David, Daniel, electricians Clive and Adam and not forgetting the 3 Romanians whom formed part of the team, superb. Everybody has been professional, helpful and courteous. You can count on this team to make a really good job. Only minor hiccups but considering the massive job it was, all resolved very quickly. Apart from a wonderful seating area, it is also a lovely dining area which we will use all year round. Many thanks to you all.

Very satisfied
Customer Service
I had seven windows triple glazed and a very professional job was done. I thought the price was extremely good. Alex, the installer, worked so hard and late. The only downside was no contact from the company during a four week pause during proceedings. All in all I'm very pleased indeed.

Great conservatory
Customer Service
We had a new conservatory fitted recently, the booking and planning process was quick and very professional, the Installer Dave and his colleague worked at a good pace and where very neat and friendly, they overcame a couple of problems due to the existing base but managed these with no fuss at all, I would highly recommend this company.

Great Service & Quality Windows and doors
Customer Service
We had 17 windows and doors replaced by Alpha Home Improvements, good quality A + rated triple glazing windows at a very competitive price. Great service from the team, we were kept informed all the way. Any small aftercare issue has been dealt with promptly and efficiently. We couldn't have chosen a better company and we are glad we used an independent local business. I would highly recommend them.

Professional skilled job.
Customer Service
From first quote to finished product everything was managed superbly. The door and finish is exactly what we asked for. The fitter was very skilled and made sure everything was to our satisfaction. The owner Jason also visited to check we were happy.

Customer Care issues
Customer Service
These people are very nice if you have no issues and don't complain about anything. But I did ..! The installation team left some debris inside and outside of the house. Although sheets were used indoors they were wet and dirty. The patio door handle proved difficult for me to operate with elderly arthritic hands and so I asked if a more suitable option might be available (at extra cost). The jointing on the windows appears quite poor and misaligned in places. They look like factory seconds. I would like to attach a photo here but there seems not to be an option to do so. The boss came to visit regarding these concerns. He was unable to cope with criticism in a professional manner and walked out refusing to deal with me further. So I am left with a door handle that is difficult to operate and windows of dubious quality.

Capable and reassuring
Customer Service
Professional in every way in suggesting the back door we should have. Clear and concise in their explanation of what we could have and produced the exact diamond leading we wanted, together with patterned glass. Everything was on time and their work was quick and clean. A good price as well!
