Sarah - Image 1 "We were really pleased with Edmund and his team’s work on our bathroom. He was friendly and professional. One thing that stood out was his attention to detail. He made sure that the tiles matched up perfectly and was a perfectionist with his work. When they left, they left the hallways and stairs cleaner than before they had arrived! Edmund had been recommended to us by a friend who works in the building business who has worked with him, so from the start we were confident that he would do a good job. We are so pleased with our bathroom!"

Sunil - Image 1 "Build of garden outhouse, front porch, repositon and installation of system boiler with mega flow. Installation of radiators, renovation of downstairs cloakroom, garden landscape and patio. Highly professional. The project had several different asks and skill sets required all of which was met to the highest standard. The team were prompt, hard working, clean and diligent. The project was agile with many moving parts. BLS were very flexible to help accommodate new asks and help come solutionize issues as and when they appeared. I felt confident I had the right people for the job and full trust in their ability. Minor touch ups were left and a very small snag list which was handled swiftly too. Edmond prides his work and ensure its done to the highest standard which includes purchasing quality material for robust build. Can't fault them and happy to refer them to anyone who wants a hassle free build"

"We recently had an extension built and the whole process was absolutely seamless. The team worked like Swiss clockwork – everything was perfectly organised, on time, and to an excellent standard. Communication was clear throughout, they kept the site tidy, and every detail was finished to a very high quality. Reliable, professional, and trustworthy – exactly what you hope for when undertaking a big project like this. I wouldn’t hesitate to recommend them to anyone looking for building work."
