Highlights
"Smashing work and a very personable gent"
"Huge thanks Connor for squeezing us in just before Christmas despite the various setbacks out of our control. We appreciate you investigating all options and checking solutions with us before beginning installation, even though it meant returning supplies and ordering some long lead-time items. The final result works very well for our needs."

Before you hire a builder
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.
