Wall insulated and plastered, floor self levered, new flooring, room painted and wall panelling
We recently had building work completed on our room, and we’re extremely pleased with the results. The team did a fantastic job from start to finish. The walls were expertly insulated and plastered to a very high standard, creating a smooth and professional finish. The floor was carefully self-levelled, which has made a huge difference, and the new flooring has been fitted beautifully. The room has also been painted to a great standard, with attention to detail clearly visible throughout. The builders were reliable, tidy, and clearly took pride in their work. Everything was completed efficiently and with excellent craftsmanship. We would highly recommend them to anyone looking for quality building work, thank you for transforming the space so well!

Excellent Job done by experienced builders
We recently had a double story extension completed to the side of our home. We are so happy with the completed job carried out by JS Builders, they were amazing and we would highly recommend them and intend to use them again in the future to complete our garden. They were punctual, excellent communication throughout the job, we added work on while job was being completed and they were great. The job was completed to a high standard. Darren and his team were friendly, and trustworthy, honestly can not recommend these guys enough. Thank you.

Outstanding work
Outstanding work carried out by Darren and his team. Front of house repointed, new slate step fitted to front door and additional repair work carried out on the roof. Great communication throughout, always turning up on time. Throughout the work Darren was courteous and considerate to our neighbours as this is an extremely messy job when removing the old cement, yet at the end of every day all was left clean and tidy.

Exceptional Builders
Cannot recommend JS Builders enough, wouldn't hesitate to recommend to anyone looking for a builder they can rely on. Their work is exceptional in quality and finish, and everything is left spotless. They always arrive when they say they will, quotes have been clear and very fair. They always give me options for every project and they are professional and respectful at all times. Theu keep me in the loop and answer any questions i have quickly and fully. They have done a number of jobs for me, including finishing and fixing issues I was left with from a different trader. I plan to use them again in future for my next projects and they were recommended by a colleague who also sang their praises. Thank you so much for all your hard work!

Fantastic work and service
We contacted JS Builders through a recommendation from a colleague. We had had half a dozen quotes about the work we needed doing but Jeff and the boys seemed the most reliable, knowledgeable and friendly specialists who turned up. From day one they were open and helpful and guided us through the process expertly. They finished the roof and all the extra bits and we were delighted with their work and decided to commission the garden as well. JS Builders were fantastic throughout and we recommend them wholeheartedly and will definitely use them again in the future for all our renovation needs. All of them were brilliant and dedicated, honest and reliable and hardworking. We are extremely happy with everything they did for us. They clearly take pride in their work and we felt confident with everything they advised and did. Darren went above and beyond for us and ensured that the job was done properly, regardless of the demands and he proved time and again that we made the right choice by going with JS Builders. Another highlight was the fact that there was absolutely no hassle for us, despite falling sick and being stuck home for over a week. The guys ensured the work continued and there was 0 issues for us. We wish JS Builders all the best and a massive thank you again. You are the best.

Fantastic Work! Very Happy Customers.
I used JS builders to undertake work to the front of the house as patio was collapsing including the wall.In addition i required works to extend the front door step for my mother who is disabled. Jeff came down last year and quoted for the patio works of which was accepted by us. No pressure or anything from them They clearly explained the works and the costs. Anyway we waited for them to carry out, of which last week they came along and carried out the works plus the additional works to the front door step. All I can say is that the job was carried out very efficiently, they discussed any issue with me before engaging any work of which I had no issue.By heck they worked exceptionally hard, cleaned up every single night before going, and again gave the necessary safety advice as my path was being dug up for the new patio. The result of their hard work and meticulous eye for perfection and detailing is excellent and the standard is Fantastic. Overall I can say without show of a doubt that I can highly recommend this building firm, family lead and friendly, this shows in the quality of work. In fact I have asked for them to come back later on in the year to carry more works to the property.

Outstanding.
I employed JS Builders to refurbish my recently purchased house. It needed insulation, new ceilings, new walls, wall knocked down, window turned into a patio door, chimney taken down, roof repairs, electrical and plumbing work. I am so pleased I asked Darren to do the work. Darren is a builder who loves his work and puts customer satisfaction before everything. He worked tirelessly morning, noon and night, weekdays and weekends and often finishing very late in the evening to finish off what he had started. He listened to my ideas for the house, offering advice and doing his utmost to keep costs to a minimum. often changed my mind but nothing was ever too much trouble for him. Darren is very reliable, trustworthy and dependable. Darren, Jeff and Daniel have done an outstanding job. I would definitely recommend JS Builders and they will be the only builders I would use in the future.

Superb workmanship
We employed J S Builders to prepare ground and lay drainage, patio base, patio, steps and platform. We would have no hesitation whatsoever in recommending this company as the standard of workmanship was excellent and the quality of work was second to none, it was always about the quality of work with them, from being meticulous and clean, even when we had a change of plan and added a few extra jobs there was no problem, let me reiterate that I would have no hesitation in recommending them to anyone who needs any type of building work carried out, thanks very much JS Builders for a job very well done.

Patio wall, porcelain slabs and steps.
Outstanding work was carried out by a great set of lads. They were always willing to explain what was going on from start to finish. They have a excellent reputation with the suppliers so delivery of materials was always on time. The finished job was more than I expected on quality and workmanship, we can highly recommend this building company. Well done lads, hope to see you on my next project.

Roofing isn't licensed, so anyone can set up - and it's a trade with more than its share of cowboys. A big re-roof must meet building regulations; CompetentRoofer (the Government-authorised NFRC scheme) registers roofers who can self-certify that, and vets and inspects them at least twice a year. Check they're on it before you hire.
Check the CompetentRoofer registerNever agree to roof work from a cold-caller at your door or an unsolicited 'we noticed your roof' note. That is the classic roofing scam.
Get a written quote that itemises access (scaffolding or a tower), the exact materials, and the workmanship guarantee, not a vague day rate.
Be wary of demands for a large cash deposit; agree staged payments against work you can actually see completed.
