Highlights
"Really polite workmen. Kept me updated. Paid what they quoted. Will definitely use again. Would recommend."
"Graham was very professional, clear in what he was quoting for and kept me in the loop through out the process. Once booked he continued to keep me informed, was always on time, or early. Great job and very tidy. Have already hired him again on the back of quality of work and the service provided."
"I'm profoundly Deaf. They communicate with me really well. The lads fixed my porch roof. Cause It was leaking badly. They did an awesome job."

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.
