We had Mainstream quote to replace 4 windows which were old and misted. After accepting the quote Richard and Vicky came to survey and measure the windows. The fitters came on the agreed date and had to put in 2 lintels in the larger downstairs windows, (removing the bricks and after cutting them to size, replace, cement and grout them in before fitting the windows). The team really worked hard to get them fitted in what was one of the hottest days of the year and cleaned up everything afterwards leaving no mess. We are very happy with the new windows and can recommend them for a professional job at competitive prices.

Wonderful company, from my first contact with Bob for a quote to the fabulous Jake and Joel who replaced my horrible old bay window with a brand new one and Richard and Vicky in between. I highly recommend this great company. Professional at all times, an incredibly high standard of work, helpful throughout and completely trustworthy. Many thanks.

We had 4no. Residence R9 windows installed by Mainstream. We live in an Edwardian Arts and Crafts house and were very keen to replicate the existing windows as our house is also in a conservation area. Mainstream were very approachable and their attention to the required detailing on the windows to make sure they replicated the original was spot on. We are delighted with the windows. We were impressed all the way through the process with the company, their attention to our enquiries and emails, the price of the windows, the prompt surveys, the great staff and the product itself. We contacted a number of other window companies at the outset but Mainstream were head and shoulders above the others in terms of their personal attention and prompt and competitive quoting.

Mainstream Windows recently fitted a new conservatory roof, bi folding doors and locks for us. From the visit to the showroom, through to the survey and installation the service was outstanding. They were very prompt and kept us updated. The fitters were excellent and we very extremely happy with the roof and doors. We could not fault them at all and would highly recommend!

Mainstream fitted Origin bifold doors for us a few years ago and we were so impressed that we didn’t hesitate to contact them when we needed three bay windows replacing recently. Once again the service was fantastic from start to finish. Competitive pricing, great product and fantastic finish. We highly recommend Mainstream.

We had bifold doors and a window fitted recently. Would highly recommend Rich and the team. Really friendly and easy to deal with. Good quality bilfolds and hassle free getting them fitted. They also kept to time frames set out at the start. Finally, very competitively priced making it superb value considering the quality of work. Thank you Mainstream

We had the glass in a few of our windows replaced and I can highly recommend Mainstream Windows. They arrived on time to measure and then again to install the replacement glass panels. Excellent communication, friendly service and they cleaned up after themselves. We're happy to call on the team in the future.

Would highly recommend Mainstream Windows for anyone looking for a trustworthy, experienced and customer oriented window/glazing company. The Mainstream team just fitted new bifold doors for us and Rich and the team were brilliant from start to finish. They offered us great advice on choosing the right doors and the whole process from order to installation was smooth, quick and easy. After spending a lot of time trying to find a local window company we're glad to have found the Mainstream Windows team!

Thanks Mainstream Windows. I called after the front door lock failed on us in the locked position. Richard came out the same day and managed to unlock the door, trace the problem and provide us with a temporary replacement mechanism so the door was still serviceable until he could get the parts for a full repair. Although hard to come by, he managed to find a new replacement mechanism for us and fitted it quickly. We are once again safe, secure and using our same keys without the need for replacements!

Had a new composite front door with side windows fitted today. Jake and Joel were very professional and did a great job. Really pleased with the door and the installation. Looks and feels 100% better than the old UPVC one.

Thank you for an excellent fitting. Replacement of two windows with 2 composite doors, including cut out fitting and making good. The team were professional, on time and extremely tidy. The installation was completed to a high standard. Thanks again, I would highly recommend.

"Always had fantastic service both from a commercial and domestic perspective. Everyone I've met has always been friendly and the quotes competitive/fair. Personally, I wouldn't go anywhere else. Previously we used others and since using mainstream, I can't say I'd go anywhere else. I damaged a handle and they came and sorted it straight away and didn't even charge for it (-:"
