Simply the best dealer around for conservatories and windows. Be reassured that you are in completely safe hands. We invested a considerable sum into a new garden room extension which was approx 6 x 4 sq metres. From the first meeting to the final product it has been a pleasure to deal with Supercraft. Their staff are knowledgeable, courteous and efficient. That goes from Dave Tooth and his team who built the base and the brick towers to hold the glazing; Dave and Ian who’d did the main frame and glazing, through Lloyd the electrician who would keep coming to check everything fitted correctly for the fitters and the tiler who I had employed myself. The finish is everything and Woody the plasterer did an outstanding job with no touch up necessary before painting. The final finish exceeded expectations and the project management throughout was excellent as each trade handed over to the next with no delay. We are perfectionists, so this review has not been written lightly . If you are considering investing in windows or a conservatory you simply cannot do better. They have also been around for a long time, the same may not be true of cheaper alternatives. We have no regrets whatsoever and would not hesitate to use Supercraft again. Many thanks Faz
Supercraft replaced our conservatory roof with a tiled roof. The service we received was fantastic from start to finish. Fab looked after us very well from consultation through to checking we are happy with the end result. This has completely transformed the conservatory into a useable room in the summer and winter. The workmen are friendly, skilled and responsible. They arrived consistently first thing in the morning and got on with the job, I did try to help keep them going with cups of tea!! I felt completely happy with leaving them to it without the need for supervision. They worked through some terrible weather to. Fab arranged the contractors – Electrician and Plasterer etc. without the need for me to organise. The contractors were also fantastic, in fact I have taken their details and I will be using them when I do some more work in the house.
Supercraft replaced our windows front and back and built a conservatory on the back of the house. Totally Organised, super job all the way through, and the after sales service that they give is amazing. I had my work done nearly 4 years ago and if I have the slightest problem, they are there very quickly. Which is worth a lot in my world. Thank you.
Just had our new Rockdoor front door fitted. Everything from the showroom staff to the installation was a first class service. I would highly recommend Supercraft. Thank you.
