Extensions- 26 Aug 2021
SSS BROTHER, They worked incredibly hard to transform our house in a timely and efficient manner, all whilst being responsive to our concerns and preferences. The SSS BROTHER did a great job extending our kitchen and backroom to create a beautiful space that we love hosting family and friends in. The job was completed to a high standard and with good communication. Throughout the work, the workers were calm and knowledgeable and - importantly for us - helpful and offered their opinion of how the extension should be built.

Extensions- 3 Jan 2025
Alexandr was a pleasure to deal with, frequently visiting the site to discuss variations with us and keeping us updated with progress. Ours was a complex project, very different to a standard rear extension, and there were variations and delays, but they were dealt with professionally and we are delighted with the final result. We would use MTB again and would recommend them to anybody.

Norbi is an exceptionally talented carpenter. He was the team lead on our major building project when we restored our Victorian house over an 18 month period. All his work was superior, from replacing ceilings and ceiling roses, to laying the new herringbone floor with electric underfloor heating. He was always polite, well mannered, and respectful. Norbi takes pride in his work and genuinely cares about the finished result in your home, a rare quality amongst many. We cannot recommend him highly enough.

Nesha was brilliant from start to finish. He was excellent at communicating before the job and was entirely professional and hard working throughout, not to mention his quote was very reasonable. He worked really hard to get the job done quickly and he did it to a fantastic standard. We are so pleased with the finished product and he was a pleasure to work with. We cannot recommend Nesha highly enough.

Bathroom Fitting- 20 Jul 2026
We hired Vasile and his team in May for our bathroom refurbishment, and were relieved he could also handle painting and floor sanding. His organisational skills took pressure off us, managing works and trades seamlessly. He impressed us from the start with his attention to detail and despite a tight schedule, Vasile had no problem accommodating our needs. When further issues emerged mid-project, Vasile handled the added time and cost pressure with calm and professionalism and managed disruption to neighbours tactfully. He always offered smart solutions that balanced technical skill with aesthetics and had a can-do attitude. His team was equally great — experienced, careful with our flat, tidy, and respectful of communal areas. We couldn’t be happier with the results! He took real pride in his work, was patient throughout, and was always present for advice and guidance which we really appreciated. We felt in great hands from start to finish — highly recommended. Thank you!

Restoration & Refurbishment- 25 Feb 2020
Malcolm and his team did great work on my house. The job consisted of full house redecoration, building bespoke shelving and built in wardrobes, loft boarding and installing ladder, replacing fencing and general pruning in the garden. They were able to turn their hands to all manner of jobs. Malcolm had a full team onsite every day and they finished the work ahead of schedule. At all times Malcolm was very responsive and worked hard to ensure that any changes along the way were accommodated. I would happily recommend Spring Construction and would not hesitate to use them again in the future.

I couldn’t be happier with the work carried out on my home. The tiling on the ground floor, the laminate flooring upstairs, and the kitchen units were all completed to an exceptionally high standard. The attention to detail was outstanding, and everything was finished neatly and professionally. He was reliable, hardworking, and clearly takes great pride in his work. The end result looks amazing and has completely transformed my home. I would highly recommend him to anyone looking for quality workmanship.
