Very unhappy with work completed. Unsafe working practices by team. Roof has more leaks than prior to works starting Damage to asbestos panels Poor workmanship Optimal roofing now ignoring my attempts to contact them. I have had a full house refurb using many contractors and have never experienced anything resembling the appalling standards set by Optimal or their lack of attempt to resolve . DO NOT USE THIS COMPANY. I am now 1k out of pocket and will have to pay another contractor to fix damage caused

Chris and John and crew were hard working and brilliant. They turned up on time and made light work of putting in double steels making sure everything was done. When building control requested added work, they had no problems getting it sorted. Hard working team cleaned up each evening. Great job. Price was reasonable.
