We had to a new boiler fitted relocated downstairs rather than it been upstairs in the bedroom. The work carried out was outstanding. You wouldn’t even know they’ve been there sheeted everything up. It was freshly decorated a new Carpets just before. The boiler went so I was a little bit worried that things were gonna get damaged, but honestly, you couldn’t even tell they’d been.
Also, my dad has asked me to put a review as he doesn’t do Facebook but he had some work on at his house and again no complaints
Thank you will definitely be recommending
