Highlights
"I recently had my bathroom renovated by Andrew, and I couldn’t be happier with the results. From the initial quotation, it was clear that Andrew really knew his stuff. The workmanship is flawless and truly second to none, all for an excellent price. Andrew is a total professional—highly skilled, a complete gentleman, and incredibly tidy. He made sure to clean up thoroughly after the job. 10/10, I would highly recommend his services!"
"It's difficult to find a good builder and Andrew is no exception. He's polite, takes your considerations into account, explains things clearly and was quick to do the work at a reasonable cost. Job done was putting in a new doorway and closing up an old one. The house is old and the walls aren't straight so it's a challenge to say the least. Thanks again and will be in touch for any future work I plan."

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.
