Professional & helpful
Customer Service
We have used Alpha Home Improvements for a number of things, namely a conservatory, new back door and new composite front door as well as a new patio door. Such a friendly professional business who were very, very accommodating and helpful. Any issues we had they assisted us promptly and considerately and sought to rectify the things as quickly as possible. Would definitely recommend.

From the beginning Alpha Home Improvements were a very efficient company. Their fitter who installed the windows was very good at his job. I would recommend this company to my friends. I would use them again.
