Highlights

"Confirmed where all electrical sockets were to be placed in the new kitchen. Plans identified some sockets but additional ones required for equipment planned for the kitchen design."

"After demolishing a previous building and replacing with a new construction the water supply needed to be reconnected."

"Williams Builders are my GO To first choice for my works and property maintenance. Being local and reliable, and honest upfront. They have carried out a lot of work for us here over the past two years now, from small jobs to block paved playground, roofing, drainage, ceilings, upvc doors and booked in for other jobs coming up."

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.
