I need to fix my craw space flooding issue.
Project Location: Pleasanton, CA
Our crawl space liner installed in 2011 could use some maintenance. Over the years we've had it, we've had various foundation work done which damaged the liner in places and pulled it from the side walls in others. We've also had some rodents make some holes in it. I'd like somebody to come take a look and give me a quote to bring it all back into tip-top shape.

When it rains the house smells musty. I have noticed that the vent in the closet (in the center of the house) where the heater is that goes tot he crawl space gives off a strong smell of moisture. I am thinking we have a moisture or mold problem under our house, but would like to get it checked and an estimate on options to have it addressed.
