Complete window replacement for a bungalow in Maidenhead at the end of 2012. Their price was competitive. Very helpful in the showroom and when measuring up. Installation done just as we needed, installers pleasant and courteous and took the time to make sure any problems were fully sorted before they left.

I cannot rate Alpha Windows highly enough. I dealt with both Mark and Allison Varney - owners - all the way through. They were courteous, responsive and nothing was too much trouble to help get the right windows for my flat. They were also very competitive on price - a real pleasure to do business with and yes I will definitely use them again

We had some secondary glazing fitted about a year ago by Alpha Windows, resulting in a very neat installation. It has worked very well ever since. We have just had Alpha Windows back to replace some double glazed units (from a different supplier) which had failed, some of these unique design features and they replaced these with exactly matching units in a clean and efficient job. Highly recommended.

We have just had 10 replacement windows and a door fitted, including a bay window, and are delighted with the quality of the installation. We looked at a number of companies over a period of a year or so before selecting Alpha Windows to quote, based on their reviews on Checkatrade and Which Local. Ian came out to do the quote and it was very nice to know that he would also be doing the installation. He was able to make several helpful suggestions such having the latches for the kitchen windows at the bottom so that I could actually reach them over the sink, and took careful note of our requirements for a grained wood finish and particular glass types and glazing bars to achieve the look we wanted. We also visited their showroom and talked though the actual installation process and were impressed with the care taken to achieve a good quality finish. They obviously take considerable pride in their workmanship. Ian, Mark and Dan arrived on time, were cheerful and polite, clean and tidy while working_ and the finish of the windows inside and out is immaculate. The key factors for us are the quality of product and installation, but on top of that the price was also very reasonable. We are very pleased and would highly recommend them.

A very friendly family firm. Very helpful with advice. Competitive quote. Team worked very hard to fix 16 windows and one door in two days. Very minor remedial work, carried out very quickly and efficiently.

From the first visit to give a quote for replacement of 6 windows to completion of the work, I was impressed by Ian and his team. There was no waffle, just clear advice and straight answers to questions. The job was done swiftly with no messing about, minimal mess, no damage and I didn't even have to touch-up the paint work around the windows. 5 months on, there have been no problems and I now have a warmer, draught-free property. I would certainly use Alpha Windows again and recommend them to others.

I've used them four times and they are excellent. They are committed to delivering quality results. They're usually the least expensive too. They also do gutters, fascias and soffits - and they do them just as well.

Just had replacement windows and door fitted and from start to finish I was made to feel a valued customer. The team were in and out very quickly but with no loss to quality of work. Only criticism is that I would have appreciated being told about 2% surcharge when paying by credit card BEFORE I paid the bill.

They were absolutely brilliant, clear quote and very friendly service. I had door and windows done (including upstairs bay window) and everything was finished to a very high standard and all rubbished was cleared away. They were a pleasure to have around and the best on price, which was a bonus. Highly recomended!!

Great local family company, gave good advice at planning stage. Good value for money. Worked hard to fit windows, roofline, & front & back doors in just over 3 days. Mark Varney & his team were cheerful, friendly,reliable, tidy, & polite. Drank lots of tea! A minor problem (rubber seal missing from bottom of door) was resolved quickly & without fuss. Excellent quality of work, I am delighted with the finished result.I can highly recommend Alpha Windows. They are members of Checkatrade & Trustmark
