Excellent Handyman Service-Painting & Mold Prevention! Stilyan did ceiling work in my rented home, and I couldn’t be happier with the results. The job involved painting and applying a mold prevention dye to a section of the living room ceiling and the bathroom ceiling. From start to finish, the process was smooth and professional. He arrived on time, brought all the necessary materials, and worked efficiently while keeping everything clean and tidy. The patience and respect towards my landlady was great too

AND the job he quoted was good value and did not change. He ended up doing some extra (paid) bits for us on request. We would highly recommend and use him again.

Living 100 miles from the job, I needed a reliable contractor I felt I could trust. David and his team more than lived up to my expectations. He renovated a complete one bedroom flat from re wire, re plumb, new boiler bathroom, kitchen, flooring, fitted cupboards etc the list goes on. All work was carried out by qualified trades people and certificates of work issued where necessary. He started the job when he said he would, worked long hours and most importantly finished ON TIME, ON BUDGET.

I'd highly recommend John. He managed our expectations well from the start - turned up on time to quote, delivered a quote the next day as promised, provided references when we asked for them (who backed up that he's a good builder), found a space in his schedule quickly to fit our job in, did it quickly, efficiently and leaving no mess afterwards. And charged us a reasonable amount for the work. Couldn't speak more highly of him, and will definitely ask him to quote on our extension when we progress with the planning.

Dan and his colleague built a rather large red brick wall for me which I am very pleased with. They were fast, tidy and efficient. They were also able to give advise on the best way to finish off the top of the wall. Secondly, they used the right mix of cement and lime to continue with the same colour mortar. They were also able to calculate exactly the quantity of bricks, cement etc. I would need so therefore there was very little wastage. I would definitely use them again.
