Highlights
"We had a loft conversion done and the work undertaken was done to a high standard and always left clean and tidy we are so happy with the finished article we had couple set backs with times of items being delivered but jef went above and beyond to make it work so thanks Jef"
"We went with Jeff to do some ground floor structural alterations including removing a chimney stack, two load bearing walls and putting in some steels. He also fitted a kitchen. He was competitively priced but what set him apart was his knowledge and suggestions giving us ideas we hadn't thought of. His team were professional and hardworking and he managed the entire process including electrician / plumber / painter. He was also able to recommend a structural engineer. I couls not fault him or his team. It's clear he's been in the trade for many years and knows his stuff!"
"Jeff and his colleagues stripped the pebbledash from the front of our house, repaired some brickwork and then redid the pebbledash, also restoring and painting woodwork. Despite a lot of bad weather that delayed similar jobs in the area, it was all done quickly and to a very high standard. Jeff informed us what was going on and when, and all the workmen were highly professional and polite. A very satisfactory experience all round."

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.
Want an extra legitimacy check?
Run the Cowboy Checker on J Preston Builders Ltd before you contact them.
