  • Cloakroom bathroom and living room refit

    10Verified Review

    One Call did some renovation work in our cloakroom toilet and living room. Paul came round for a preliminary meeting and gave us loads of useful advice. Great work by George and Tony who were on time/ early every day. They were professional, really respectful of our home and the quality of their workmanship was second to none. We never had to worry about a thing and they always kept us informed of progress. Everything was done on schedule. Can't recommend them enough and we plan to ask them back for further work.

  • Insulation of Summerhouse and Garage

    8.5Verified Review

    The overall experience was favorable, although there was a need for additional electrical work that wasn't initially included in the original quote. While these extra tasks were essential for safety reasons, it would have been preferable to be informed about them from the outset, allowing us to make informed decisions. Despite initial delays related to materials and quote adjustments, I cannot find fault with the quality of the tradespeople on site and their professionalism. While not the most budget-friendly option, the adage holds true—you get what you pay for. Thank you once again!

  • Bathroom refit from bath to shower unit with painting and tiling

    4.5Verified Review

    Up until the painting everything was fine and then they put the wrong paint up and there was bad staining on the walls.

  • I need a toilet seat fitted correctly.

    10Verified Review

    A lovely lady called me to explain what trader I would actually need to carry out my task. She didn't have to do this so I think this deserves a review. As it shows great customer service.
