"He has been our builder for over 20 years and he is does all kinds of building and decorating work for us. I don't need anyone else and I definitely would never use anybody else. Am always incredibly happy. He is so trustworthy and he fits his schedule around me. Always on budget sometimes over time because I think of new things he can do to. Never any problems. If there are which is very rare, he is always back really quickly to fix it free of charge."

Epsom Customer5.0 / 5

Highly recommended. Jim is extremely professional with a particularly good eye for detail. His work is high quality and neat and he leaves everything clean afterwards, He is very pleasant to deal with and easy to contact when off site. He's clearly very experienced and has the knack of being able to explain things clearly. He's also good at offering ideas and advice. Very trustworthy and I'd certainly use him again.

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.
