WARNING!!!!!!
This company have refused to repair my bifold doors claiming I had abused the doors, it was windy or bad use!
The company have been called out on 3 occasions on none of those times did they fix the problem!
The owner was extremely rude and got quite abusive! He then claimed I did not buy the doors from him! Yes I did hang up on him at one point as I was getting nowhere with his attitude.
The engineer arrived at my door with a cigarette hanging out of his mouth on one occasion, very professional!
Problem still not rectified his only response was for me to pay £500 for new hinges

Had a conservatory and porch with new doors, conservatory carpets, plastic wall covered in black mould and very damp, smells, have to clean every couple of months. Plastic sheets with roof fill with water. Black mould on sealant and walls. Porch leaks when it rains and is mouldy. After care very poor. Say they are coming out to see and sort. But still waiting.

Installation was quite good. One piece of glass was wrong size but still insisted on payment.
Customer service is dreadful, took ages to fit the glass and to do some minor adjustments when doors settled.
Very poor.

Bestbuy Home Improvements dismantled an old conservatory and built a new larger 3mx10m family room / washroom. A great company to deal with, competitive prices / no pushy salesman / quality work! They quickly quoted me with a detailed quote through the post within 2-3 days of the site visit complete with computerised visuals of the end result.
The work was professional and a well skilled team operated throughout the project (The brickwork for example has been commented on how good it is by friends who have looked at it) The whole project did take longer than I expected, but maybe this was me wanting

Brilliant company from start to finish. I had a front and back door installed by this company 10 years ago, and the doors are still going strong and looking good. But I still got 3 companies to give me a quote. Best buy was the most competitive quote, no pressure, friendly , helpful staff. In less than a month from the original quote, I had 9 windows installed. thank you very much to everyone at best buys.

Bestbuy had replaced the windows in my previous house, so after I moved, I had them replace the doors and windows in my bungalow. I was very pleased with the quality and workmanship again, so when I decided to replace my conservatory, which was 15years old and had seen better days, with a proper extension with a 'Guardian Warm Roof', which will become my lounge / diner, Bestbuy was my first port of call. I also wanted my existing lounge / diner to become the 'master bedroom' with a new window installed in the side wall. All the above was done under 'permitted development'. I just showed Mark at
