Crawl Space Waterproofing in Knoxville, TN

Keep Your Crawl Space Dry In Knoxville's Wet Climate

Water in your crawl space isn't just a seasonal problem. Every drop that gets in threatens your home's foundation.


I've fixed hundreds of wet crawl spaces in Knoxville. Most homeowners wait until water damage spreads to their floors or walls. By then, repairs cost thousands more than prevention.


At Forever Guard, I find every water entry point and seal it properly. No temporary fixes. No band-aid solutions. Just complete protection that keeps your crawl space dry year-round.

The Real Cost of a Wet Crawl Space

Water damage starts small but grows fast. Here's what it costs you:

Foundation Problems:

  • Cracking concrete
  • Settling issues
  • Weakening walls
  • Shifting support beams
  • Unstable floors

Money Losses:

  • High energy bills
  • Expensive repairs
  • Lower home value
  • Insurance issues
  • Repeat fixes

Health Risks:

  • Mold growth
  • Bad air quality
  • Pest problems
  • Allergy triggers
  • Breathing issues

Most water problems hide until damage is done. But you might already pay the price through higher bills and repair costs.



Don't wait for small leaks to become big problems. Let's find your water issues now and stop them right.

Common Water Entry Points in Crawl Spaces

Water finds every way in. Here's where we look:

Surface Problems

● A poor yard slope pushes rainwater toward your home instead of away.

● Clogged gutters overflow and send water straight down into the crawl space.

● Short downspouts dump water too close to the foundation.

● Pooling rainwater around the house seeps into the soil and walls.

● Cracked foundations open the door for moisture to enter.

Underground Issues

● Rising groundwater slowly pushes into your crawl space from below.

● Heavy soil pressure forces water through weak points in the foundation.

● Hidden springs under the property feed constant moisture.

● Shifts in the water table bring more water up into the soil.

● Clay soil holds water and creates long-term dampness.

Inside Troubles

● Pipe leaks drip directly into crawl space areas.

● Wall seepage lets water pass through concrete pores and cracks.

● Open vent gaps allow rain or humid air to sneak in.

● Small cracks widen and seep water with every storm.

● Condensation builds up on cool surfaces and fuels dampness.

● Finding water sources is key. Fix the entry points, and you fix the problem.
