Highlights
"Gary did our bathroom refurbishment to a very high standard and tackled any issues that came up. I would highly recommend him and would definitely use his services in the future"
"Gary has completed a few jobs for us and on this occasion it was a Patio and French drain. He does a variety of work and the quality of his work is great. He is very experienced and knowledgeable, doesn't cut corners and will always give good advice when necessary. He has pride in doing a good job and works quickly and efficiently. Perhaps most importantly, Gary is reliable. If he says he's going to turn up he turns up and doesn't let you down. He's highly recommended."
"Gary is exceptional. Rarely can you find someone this good, knowledgeable and conscientious! He can follow plans with ease, understands everything he is doing (understands what should be done too!!), advises and can quite frankly do whatever you need! He's done countless things for us, but the last job for us was converting a loft - not a small loft, a huge loft that is now a 2 bed flat - and upgrading and converting the rest of the building to 2 further flats. Works included, re roofing, bricklaying, windows, doors, insulating walls and floors, sound proofing, plastering, the list goes on!"

Gary removed a fireplace for us and made good the wall. He’s clearly very talented and really cares about doing a great job and that really comes through in the detail of his work. I would completely trust Gary for any future building needs. I find him very reliable, honest and friendly.
Quality service from Gary in every aspect. Gary has been a real support throughout our house renovation, from providing a sincere quote, to his ability to take the stress out of the work for us. Gary handled everything we needed including the steel ordering, skip hire, and completing the work quickly but still to a great standard. His quality of work matches his amazing personality whereby no question was a stupid question and his advice thoroughly helped us.
Gary carried out professional work from start to finish. It's a rented property and he arranged all times and dates with the tenants. He kept me well informed throughout the job with photos and messages. The completed work looks excellent. I will certainly use him again.
Gary came to us by recommendation and we cannot speak highly enough of him. He is friendly, professional and highly skilled. He worked non-stop (throughout a sweltering heat wave!) and has transformed our entrance room in less than 4 days! Gary paid attention to detail and suggested practical changes to our plans that made the space more functional. Felt very comfortable with Gary in the house with or without us there. So pleased with the work done and would highly recommend.
I have used Gary many times and he always does a great job. Nothing is too much trouble and he is very reliable, clean and tidy. He seems to be able to handle all types of building works from fitting kitchens, bathrooms and tiling to loft conversions including roofing. Can’t recommend him enough.
An excellent job on the extension. The brickwork is excellent.
We asked Gary of GFB builders to carry out some redecoration and refurbishment work which was required. Gary has worked with us before and apart from being a really good and knowledgeable builder he is a thoroughly good guy and always straight and fair. There's not much he doesn't know and he always starts and finishes when he says he will. Super reliable we are very happy with what he's done for us.
This is the 2nd time we have used Gary, and again he has excelled. We have completely redone our kitchen and utility room, including a tiled underfloor heated floor. Our house is a little old, so the floor was uneven and the walls were wonky, but those challenges were overcome, and the new kitchen was finished on time and to a very high standard. As usual, Gary cleared up at the end of every day. We have already booked him for a bathroom renovation in 4 months time.
Another excellent job. Gary is friendly and reliable. Job carried out on time and on budget. Thank you
This is the 3rd time we have used Gary for building work on our house. He is amazing, professional and quick. His attention to detail is outstanding. Gary has recently completed our Kitchen and utility room. His workmanship is stunning. He is also quick and accommodating. We work from home and have 2 little ones and the disruption to having our kitchen and earlier in the year both our bathrooms with Gary was so minimal! And that is gold in my book. Just a lovely person who happens to be one of the best builders/tradesmen we have worked with. Will always and only go to Gary for any works
Fantastic work, very pleased with new room. Gary is highly skilled with great attention to detail. Work finished on time to a very high standard. I would highly recommend
The bathroom required complete refurbishment. It has been transformed from a drab and dreay room to a plush stylish boudoir. Gary treated our house as his own, as in he left where he was working spotless when he finished for the day. Cannot recommend highly enough
Gary was asked to price for a job to redecorate/refurbish my house as I am looking to move my elderly mother in. Once we had agreed a price and time frame he set to work. Through the project Gary was professional at all times and very knowledgeable. He would always come to me with solutions if there were issues. I'm really pleased with the result and how the project went and that is due to Gary's professionalism, good humour and commitment to doing a good job. This sort project could potentially be stressful, but Gary made it easy. Thanks Gary for your flexibility and always great advice.
Gary was very professional and work was carried out very quickly. Hard worker and didn't even stop for lunch like alot of tradesmen. Done a wonderful job fitting new downstairs toilet with basin and window. Will only be using Gary for future work.
Gary did a great job for a very reasonable price. Discussed our requirements with us throughout and finished the work to a high standard. A multi-skilled professional whose expertise I would call on again in future.
