Jeff and his team have just completed the extension of our daughter's bedroom. We were delighted with how it went from first contact. The quote was very reasonable and the work was completed in a highly professional manner. Jeff and his team were always punctual and ensured the work was completed on time.

They even took care to leave the site clean at the end of the day, our neighbour's commented that they'd never seen such tidy builders! Overall we were extremely pleased with all aspects of Jeff's service and would definitely recommend anyone considering home improvements to give him a call.

Jeff and the team were outstanding. From the minute they started to completion (only 6 weeks!) We have 2 young children (one 6 month old baby) and every night they cleaned up and we were able to stay living at the house whilst the work was complete.

Jeff is extremely professional and did our loft conversion to an exceptional standard. We would definitely use them again and have recommended them to our family to have their loft and kitchen extension done too. 10/10

When I was choosing a a builder for my recent loft conversion, and having zero experience in any kind of renovation, it was important to find a team I could trust and who evidently knew what they were doing. I couldn’t recommend TSTL more highly for this. They were clear, organised, trustworthy, kept me updated on progress and what they needed from me at all times. Jeff had great ideas on how to get the best out of the space and it’s clear he and the team are highly experienced in what they do. The finished loft looks brilliant and I’m so happy I went with TSTL!

Incredible service - nothing was too much trouble and Jeff was always on hand to deal with any problems or questions we had. We were kept fully updated at all stages of our build and were happy to accommodate all of our requests regarding individualised work. We love our loft conversation and can’t imagine ever being without it - it has changed the dynamic of our house and given us more space than we could ever have imagined.

Due to their popularity we had to wait almost a year to start our work but so glad we did - definitely worth waiting for and have already recommended them to many friends already.

Fantastic work from a genuinely nice company

Thank you!
