Highlights

"I had the cladding replaced on my home, with super quilt insulation & a Tyvek water proof membrane installed. Marks quote was very competitive and the standard of work on my home was excellent. Mark & Rob replaced the guttering for us, built a timber frame under a UPVC window which hadn't been done properly by the window fitters many years previous and also replaced a double glazed window which had popped and was leaking (unbeknown to us). I would highly recommend using Miall & Barnes. They're polite, honest and the standard of their work is very high."

"Mark and Rob had great communication throughout, and were very knowledgeable at finding solutions when quirks came up on the job. They were very tidy and cleaned as they went on what was a very dusty job. Would recommend and will use them again!"

Smart checks

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.
