James and Issac Oak installed gutters on my house without telling me that I didn't have a drip edge/flashing so they would only work at 80% function. When I complained about the terrible leaking James Oak offered to refund my money, but in the end went back on his word and refused to pay. Lied several times including that this 80% function had been explained to us at estimate--except no one was home when we had the estimate done! Bad businessmen. I'd never work with them again. I just wasted my money since I still have water pooling in my patio.
