Booked John and his team to replace the guttering, fascias, soffits with recovering of a small flat roof, on my 1970's house. John noticed that my felt was literally crumbling away when the work started — then we discovered the main support timbers were rotten and the whole flat roof needed replacing. Sounds like a nightmare doesn't it? Luckily John and his team made it smooth sailing instead. Excellent communication, clear explanations, super responsive turnaround and very competitive pricing. A ridiculously hardworking crew, super tidy, helpful and courteous. The other trades on site made a point of telling me how good they were. I'd recommend John and his team to anyone needing roofing or guttering work done, anytime.
"John and his team did a fantastic job to repair my conservatory guttering. John turned up within 24 hours of phoning him & completed the repair efficiently & gave a competitive quote. I would highly recommend CNEM Property Maintenance."
"Had John and a team out to have a look at my roof which was leaking around a chimney, replaced some broken tiles, done lead work — very pleased with the service, fast, clean and friendly."
"John came, spotted the issue, sent his guys to do a temporary fix the next day, until he could return the following week. Then replaced my roof in 4 days in the middle of winter. Charged me what they quoted me, builders were tidy, quick and polite, and managed to do it without scaffolding saving me some cost. Would recommend them again."
"Good quote, good communication during the fitting of three new roofs. Excellent team, high quality work, cleaned up well after too. Very good, highly recommend."
"Initially had my doubts as I have been let down by other roofers in the past. I was pleasantly surprised how helpful, professional, polite and how clean he left our property. I had a couple of tiles replaced, some pointing refreshed and my guttering cleared. Very good price & excellent work practice — 5 Stars just doesn't seem enough. I would like to thank John for restoring my faith in the profession."
"Booked John and the team to replace an old rotten fascia. They suggested we also replace our guttering, which we both agreed was fairly tired looking. They priced it up and fitted it with superb professionalism. Would recommend for all roofing and gutter jobs!"
