We hired DYC to clean the shake roof on our summer cabin, replace some shakes, and put on a moss treatment. We didn't realize it until they were finished, but the nails they used to replace the shakes were too long and went all the way through the roof and ceiling. When we called David about this, he offered to fix the problem (hundreds of nails sticking through the ceiling) for additional payment. He finally agreed to a $1,000 refund if we would sign a document absolving the company of further liability. We did so but it took him THREE MONTHS to complete the refund. Meanwhile, we had to repair the ceiling ourselves. They were nice people but I wouldn't hire them again. read more
