## In customers' own words
_Verbatim quotes from this trader's public reviews, each attributed to its source:_
> "We used DeMa Construction last year for remodelling our kitchen & dining room & have just had them back to upgrade our lounge with the construction of a Media wall with the associated electric work, the whole room was also replastered & decorated. The quality of the workmanship is outstanding & Marcin is a perfectionist. He is extremely polite, knowledgeable & hard working & is probably the tidiest builder in the world !!! All in all I am extremely pleased with the whole experience & have recommended him to friends & neighbours."
> — Karl B (5.0, via Checkatrade)

> — Anonymous (5.0, via Checkatrade)

## 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.
