I recently had Luke and his team widen an opening between two rooms in my property, which was a sizeable job requiring the installation of a steel beam. The work was managed efficiently, and great care was taken throughout the project. I’m very pleased with the results and would highly recommend Luke and his team for their professionalism and attention to detail.

AVOID AT ALL COST and it is the right company. Don’t pay him or his partner Nick Moules any money. Nick will probably visit your home within a couple of hours of posting the job (making you feel confident that your job will be finished as quickly as you need it to be) send you links to the materials to be purchased, ask for deposit and then stop all forms of communication. They will quote +/- £20 to the other tradesmen. Should be banned on this site.

Marlon refitted my wall mounted bathroom fan heater which had exposed wiring. He replaced two wall switches - one had a chipped fuse cover and the other had wood filler smeared over it. He also replaced the broken metal back box to a double wall plug socket and refitted the socket outlet. He gave me a clear, comprehensive quote - no additional costs. He carried out the work promptly and efficiently. All in all a really good job. I would definitely hire him again. Thank you Marlon.

A guy called Michael showed up, gave it all the large talk about what he would do. Gave him an address for another project also out of goodwill so he didn’t have to buy another lead. Promised to get back to me despite promising me he would return that week to do the work. Instead just ignored every phone call and message. He kept mentioning about wanting to do it in the evening…. This was impossible as it was a shopfront. Absolutely no balls, AVOID LIKE THE PLAGUE!
