Highlights
"John Cawley Ltd were great to work with. They were reliable, trustworthy and went out of their way to sort out any extra work which they came across."
"All round exceptional again - we've used John before at our last property to remedy poor work done by another roofer. This time we had a leak and he was out quickly to inspect, advise and then returned promptly to sort it, along with a few other bits including flat and pitched roof-work. Always trustworthy, fairly priced, courteous and clean. We continue to recommend him to neighbours."
"John is a very trustworthy professional who is experienced, reliable and competitively-priced. He will get the job done and he won’t leave a mess!"

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.
