Initially we were really pleased with the work Handy Sanders did. They sanded, filled in gaps and coated the floorboards throughout our house. However after a few weeks the gap filler began rising up between the floorboards and it now sits a few mm above the boards and has set solid. It looks and feels really bad. We have contacted Handy Sanders multiple times asking them look at the problem and to fix it, but we've been ignored. The work was supposed to guaranteed but they're not interested. We're really disappointed with the poor quality of the work and their customer service.
