Had another co. who didn’t seem to think anything needed to be done, come out several yrs. ago. Then it got worse!!! So much dampness & awful smell until your service was done! Salesman took time to explain process. I misunderstood some but would be good to come back out & go over while process is being done. Gentlemen who did the work did help with telling me & showing as they worked the 3 days to complete. On paper is not as easy for me to understand as seeing the process. Jim, salesman, was very kind. Appreciate being able to change the installation dates a couple of times due to circumstances beyond my control!
