Latest reviews

  • Flat roof leaking into bedroom

    John came to my mums house within 24 hours of posting the job, was in time, professional and courteous. He identified the problem areas immediately and fixed them straight away, all the while explaining everything clearly and professionally. I was extremely lucky that John bid for this job, he didn’t make a penny off us, he refused payment to help my Mum out. He has a loyal customer for life now, a proper gentleman and a very professional tradesman. Hire him, you won’t regret it.

  • Roof extraction vent

    John offered a fair quote and it was clear from the off that he knew what he was doing. His experienced team did quality work on time and we’re very tidy. You may get cheaper quotes, but when it comes to your roof, for me, quality is more important.
