This is a long term review of a log cabin design shed that I wanted to use for a workshop. The shed has now been in place for just over 3 years and never, never again will I purchase anything from this company. Initially, some of the timber was damaged, I had to have all the felt replaced and re-roofed twice as it leaked as soon as it rained. The windows and doors had to be replaced as they didn’t fit properly and leaked. The door still leaks and still doesn’t fit properly. Due to the design of the interlocking tongued and grooved timbers the wind just drives the water straight through the walls and the interior is now water stained and damp in a number of places. None of this wood is properly seasoned or pressure treated and has moved considerably in the warmer weather, which obviously is causing some of the leaks and issues mentioned. I have re-treated the outside twice since I had it built. I did e-mail recently but was told I am afraid that at present I can only offer advice as your order is out of leadtime. With the recent bad weather the roof is now leaking again badly onto electrical items that have been ruined. I am appauled that a company can get away with such poor quality design and material and would warn people not to use this Waltons. I have tried to be remain positive about my experience with them but at my time of life I don’t have a lot of money and can’t afford to replace it. I’m not sure what the so called 10 year warranty is for or what it covers as they don’t seem prepared to honour this. One year to sort out leaks etc is not enough on a purchase of this scale and outlay, especially as the timber will expand and contract. Such an unprofessional attitude. Please look elsewhere is my recommendation. Just found more leaks coming through the roof and walls. On inspecting the roof closely I discovered the wrong roofing nails were used on the felt and with the hot Summer they had lifted. Cowboys come to mind. I think having a long term review is important, as customers need to know how these cabins cope with the British weather. Basically they don’t.
