Highlights
"Simon and his tradesmen did a fabulous job. The project was completed on time, to a very high standard. Attention to detail was excellent. Would highly recommend."
"Simon and his team completed our house extension and I couldn’t be happier with the result. From the start he was clear on scope, timings and communication throughout was excellent. They were punctual, respectful of our home, and kept the site as tidy and safe as possible day to day. The quality of workmanship is really a high standard, well-finished, and properly thought through. Any questions or small changes along the way were handled professionally, with options explained with better solutions instead of our architect. I would happily recommend them and would use them again."
"He's a very friendly, reliable tradesman - have news him a few times."

He's a very friendly, reliable tradesman - have news him a few times.
Demolitshed two large Ravinder brick flower beds, relocated two bay trees and then installed two very large soakaways and two long runs of drainage. Hardcore and then spreading Cotswold stone. Wonderfully polite and punctual. Estimate spot on too.
He's extremely punctual, very polite and knows what he's talking about. Did a really good job!
I found Simon at STL Ltd very helpful and professional throughout the works. At all stages he would let us know what was being completed and how long it would take. Apart from some extras we requested, everything was as per the quote. Would definitely recommend him. Regards, Keith.
Simon is highly knowledgeable in the extension and refurbishment sector. Worked alongside him on many jobs and he runs the jobs efficiently and too the budget
STL have done a fantastic job building my new summer house from the ground works including concrete slab to the timber frame and roof and making it water tight I will be getting them back to install all the external cladding.

Before you hire a builder
Never pay a large deposit up front — agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.
Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced.
Be wary of a cash-only price or pressure to start tomorrow — both are red flags for an unaccountable job.
Ask to see a portfolio of completed work like yours, plus recent references you can contact.
Check the credentials and registrations that matter for this work — and that they are current.
