I had Maintenance Works out to fit my gas fire (without any pipes ready to go), the marble and fire surround, we also couldnt get the hearth out so this was done for us too.
The guy was brilliant, gave us advice on our other fire we want fitting and did a great job. Highly recommend these guys. We also had a team of fellas sent from Maintenance Works to complete damp proofing in my hallway and again they did a great job. I'll definitely be using them again for further work on my house. Spot on, thanks guys.
