## In customers' own words
_Verbatim quotes from this trader's public reviews, each attributed to its source:_
> "Greece came to unblock our sewage drain, he came promptly and unblocked the drain, he gave valuable advice too, thank you. He is definitely a number to keep if having drain problems."
> — Anonymous (5.0, via Checkatrade)

> "Reece was great, was able to come within the hour. We were a bit worried as we had a dip in our paving and thought it would be a collaspsed drain pipe. Reece explained to us it wasn't as bad as that. He knew what he was doing and knew the source of the blockage. Reece was also competitively priced. Would definitely recommend."

## Before you hire a drainage contractor
_What to check when choosing this kind of trade — general guidance, not a claim about this business:_
- Confirm they cover your area and can actually come out in your timeframe before anything else.
- Read recent reviews for reliability and turning up on time — not only the quality of the work.
- Agree the call-out fee up front, and be wary of large upfront deposits for an emergency job.
- Run the Cowboy Checker to confirm the business is real before you let anyone in.
