Tradesman turn up on site when they are due & you are kept well informed about who will be arriving & when & what will be done on the day. I have had an extension built by this company & it was done within the 8 week time frame & met completely with building regs. Recently had deckboards & fence panels replaced & a hot tub cut up & cleared. Very pleased with the all the works that have been completed. The tradesmen always tidy up too. 5 STAR"

## Before you hire a builder
_What to check when choosing this kind of trade (general guidance, not a claim about this business):_
- 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.
