Highlights
"Jamie and Vas from JFL Building Ltd did a great job on our new roof . The work was carried out to a high standard, they were professional throughout, and communicated clearly from start to finish. The job was completed efficiently and the price was very reasonable. We would not hesitate to recommend them."
"Our bathroom was not a straightforward job. It was originally a poor loft conversion with sloped inconsistent flooring. Jamie explained from the outset that it wasn’t straightforward and we discussed various options. Throughout the project, the communication was excellent. The floor is now secure. Jamie fitted a shower, standalone bath, new sink and new towel rail for us. He and Vaz were also able to fit a shower head directly into the ceiling which completely transformed that particular space. We wouldn’t hesitate to recommend Jamie."
"Jamie is extremely efficient. A problem solver, knowledgeable and reliable. Very respectful and communicative throughout the works. I know we plan to use Jamie for further projects around the house. I would highly recommend."

Smart checks
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.
