"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."
