## In customers' own words
_Verbatim quotes from this trader's public reviews, each attributed to its source:_
> "If you’re looking for honest builders, quality workmanship, good value and impeccable customer service then look no further. Highly recommend Cornerstone, no job is too small for them and they do not cut corners. They also have a team of experts eg. Plumbers, Electricians and Builders to save you money. They do everything from kitchens, bathrooms to full house renovations. The most important thing to me was time and commitment. Cornerstone are extremely reliable, they turn up as scheduled and completed jobs as agreed. Furthermore, they provide excellent aftercare. Cannot recommend them enough."

## 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.
