Highlights

"Gareth did a very good job for us despite some unexpected issues with the plaster bonding to the Artex . He suggested to plasterboard the ceiling to rectify as he wanted the perfect finish and didn’t charge for the additional labour this entailed. Would recommend Gareth."

AnonymousCheckatrade5.0 rating

"Gareth replaced exterior timber and treated and stained existing timber. Repaired rendering and treated and painted existing rendering. Over several days, he was pleasant, arrived promptly, cracked on with his work and left the work area tidy each day. A great job done - very recommended."

Before you hire a plumber

Agree the call-out fee, the hourly or fixed rate, and whether parts are charged on top — in writing — before an emergency plumber starts. Out-of-hours overcharging and 'while I'm here' add-ons are common complaints.
Be wary of a plumber who, on a first visit, says your whole system or boiler must be replaced — get a second opinion and an itemised quote (parts and labour separately) before agreeing to major work.
Gas and boiler work is a separate, regulated trade — not general plumbing. Make sure anyone working on a gas appliance is specifically registered to do gas work, and ask to see that registration before they start.
Look for consistent reviews across several named sources, not one polished profile.
Check any verified credentials, and that the business details independently check out.
