Highlights
"James and his team cleared the moss from our roof. This revealed a major problem with a section of broken tiles, rotten rafters, fascia boards and soffits, which were replaced. He also painted our garden room and carried out other minor repairs. All work was carried out to his usual high standard and everything was left clean and tidy."
"James and his team replaced our roof and roofline, arranged the installation of new windows and painted the exterior of the house. We were very pleased with the work and would wholeheartedly recommend James Knott and Sons to others."
"Attention to detail is outstanding"

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.
