    Roof Replacement

    Posted 5 days ago

    Roof replacement (full) including joists

    Sean was incredibly helpful and efficient. At short notice came to inspect the roof issue (which required the whole roof to be replaced), quoted on it, and within a week of quoting completed it to a fantastic standard. Even the rain did not deter him and his crew. All rubbish cleared and site left neat and tidy. Highly competitive quote too. 10 out of 10.

    Bay window roof leak

    Had a leak coming from the flat roof above bay windows. Spoke to Sean who promptly arranged for an inspection and gave me a thorough overview of the issue. Polite throughout, Sean and team were able to get the issue sorted with a fast turnaround.

    Proactive, responsive, diligent and a pleasure to work with.

    Sean has helped with two roofing matters we've discovered since moving house. Both times he was extremely responsive and proactive. In particular, he was able to squeeze in an emergency repair over a holiday period which was a great relief and for which w are truly grateful. We're glad to know that we can call on Sean for anything that may come up in the future.
