Job Stories From Portland, TN
Basement Waterproofing in Portland, TN

This customer in Portland, TN had a home being constructed with a finished basement to be included. To prevent any water issues before they happen, we waterproofed his exterior basement walls and installed drainage pipes around the entire exterior of the structure, and connected it to a LawnScape system. While this is not a usual request on new construction, the customer wanted to make sure water intrusion would not be an issue in his new home. A home with a finished basement that develops water issues can be a very big and somewhat destructive job, so to mitigate that issue we waterproofed the walls as they were being constructed. At Frontier, no matter what the issue is we can come up with a solution that works for you and your home. Every job is different and requires different solutions.

High moisture in my crawlspace led to mold growing on floor joists, which ultimately led to several rotting away and needing to be replaced. I'm looking into crawlspace encapsulation as a means of resolving that issue, and making any future work in the crawlspace much less of a mess.

We have a significant amount of flooding that occurs in our basement. We have literally seen the water shoot out if the bricko blocks like someone took a cork out of a champagne bottle. We were hoping to finish out the basement at some point but obviously need to seal it off in order to make this feasible.
