I paid £1000 for a summerhouse back at the beginning of October, I also paid for the company to install it. It has leaked like a sieve from day 1, through the windows, through the door, and water even seeps sideways through the corners and one of the side panels gets soaked. Large patches of the walls are perpetually damp to the touch, and after rain there are small puddles inside the structure. I know the weather has been bad, but I have an older shed from a different company in my garden that remains totally water proof after 18 months. The summerhouse company have made 2 attempts to rectify, first by adding guttering, second time by adding sealant everywhere, but neither has helped. I have asked for a refund and removal of the summerhouse because I can't use it if it is damp and leaky (I was planning on insulating it and using it as a home office.) The company, after 3 months, now say that they do not guarantee that the structures they sell are water proof and perhaps I should paint it. However I paid extra for a pressure treated shed so I didnt need to paint it, and the men who erected it confirmed that it did not need painting! How do I resolve this? Any advice would be wonderful.
