Recent Testimonials
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!

Completed a double storey house extension with the addition of a glass balcony. Very pleased with the workmanship, always courteous, hardworking. Real attention to detail explained the process as they went along. Always starting early and finishing late to see the job completed. we were delighted with our finished extension we would thoroughly recommend this company to work with.
Lisa F
Excellent all round - couldn't have asked for more - highly recommended.
We were extremely happy with the service we received from Jeff and Sharon on our project (two-storey side and rear extension). Jeff was personally on site for the whole project, and his attitude was great - nothing seemed to be a problem. the work itself was to a very high standard and completed on time. Sharon took care of all the paperwork and administration and was always on the ball and responded to our queries right away.
During the project we added some scope, and the charges for the additional work were very fair.
A very trustworthy and capable company - have absolutely no reservations in highly recommending.

Jeff, along with his co-worker, Kevin, worked on our terraced kitchen extension which took roughly 3 months. The experience couldn't have been better. They went out of their way to keep us comfortable in our home whilst the works were going on which can't have been easy for them. Jeff's experience in the building world was so helpful for us (especially with any updates on costings) , and the results were amazing and we couldn't be happier. Jeff and Kevin were reliable, considerate, turned up everyday without fail, and worked long hours to make sure our works were completed on time. We have recommended TSTL to anyone who is wanting an extension and would, without doubt, use them again.
ChrisH
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.
