## In customers' own words
_Verbatim quotes from this trader's public reviews, each attributed to its source:_
> "We are very happy with the work that Alex and his team carried out yesterday. They arrived on time, got on with the job and were professional, efficient and friendly. We would highly recommend them!"
> — Sally B (5.0, via Checkatrade)

> "Alex and his colleague were here nice and early having brought the job forward - quoted and completed in one week! The options (different lintel types) were explained to me, so I knew exactly what the options were and what work they would do. They took care over protecting the patio / plants, and generally todos up after themselves (I just had to sweep and mop the brick dust that got into the kitchen). I’d recommend Alex - pragmatic, no-nonsense, good value, polite and friendly. What more could you want?"
> — Anonymous (4.7, via Checkatrade)

> "We hired Alex for a full garage conversion and was impressed throughout. The team delivered high‑quality work across every stage, including structural changes and insulation. Communication was clear, issues were handled proactively, and the site was kept tidy. The final result exceeded expectations and has added real value to the property. I would confidently recommend them."
> — Anonymous (4.5, 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.
