## In customers' own words
_Verbatim quotes from this trader's public reviews, each attributed to its source:_
> "10th time I ask AZ to help and as usual, I am sincerely blown away by the service. I had a bad leak going to downstairs neighbour. Adam was very busy but made sure he found time to see me and arrived bang on time on the day. He had met me explain the situation before on the phone so could get straight to work - he was able to Find the leak in 15 mins, removing the floor only where needed and identifying the cause of the problem - while documenting the process for my insurance. All done in less than 2 hours . I am always 100pc reassured when AZ team comes to the rescue and I can't recommend them enough!"

> "It is always a pleasure to see Adam for our annual boiler service and everything went perfectly according to plan. On this occasion he also moved some drainage pipes behind the washing machine to make it fit better in its alcove and allow the oven door to open fully. He made very light work of that with a perfect and gratifying outcome."

## 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.
