Project Location: Wilsonville, OR
I have discovered a leaking drain pipe in the crawl space under my house, and I am not sure how long it has been leaking and, what damage it has caused other than standing water. The issue I have is the way in which the house was constructed there seems to be no access to this area?? I can see the drain pipe through a foundation vent screen. The crawl space looks to have 36" plus clearance between the floor and ground. I would like to get a recommendation and estimate to create an access to this area as well as repair the pipe, and seal the crawl space. I hope this is something you can assist me with? Thanks, Greg LaPlante Additional information: How did you hear about us: Television Main Area of Concern: Crawl Space
