Case Study: Crawl Space Repair in Huntsville, Alabama

Water in a crawl space causes all kinds of problems for a home such as mold growth or bouncy floors. This was the concern of one homeowner in Hunstville who called on AFS to protect their crawl space from moisture.

One of our Certified Field Inspectors, Dustin Loeb, went out to inspect the property. He found groundwater collecting below the home and noticed general signs of moisture throughout the crawl space. Based on his findings, the installation crew placed drainage inside the crawl space to control the flow of groundwater and installed a 3,000 square foot vapor barrier to block outdoor moisture.


The Challenge

  • Moisture problems inside the home
  • Groundwater collecting under the home

The Solution

  • Crawl space drainage
  • 120-mil vapor barrier
  • Sump pump

The Impact

  • Healthier home
  • Protection of floor structure
  • 55% relative humidity in crawl space

Before Crawl Space Repair:

Moisture in the Crawl Space

As you can see in the image, the crawl space had an ineffective vapor barrier loosely sitting on the floor. There was no protection from moisture along the walls. Since this vapor barrier wasn’t providing much attention, there was a high amount of moisture in the crawl space—creating a damp and uncomfortable area.

Crawl Space Drainage Problem

This image makes it clear that the crawl space had a lack of drainage. As a result, it was easy for groundwater to collect under the dirt floor of the crawl space (especially after a storm) and contribute to the damp environment below the home.

After Crawl Space Repair:

Crawl Space Drainage

First and foremost, our installation crew lined the crawl space with effective drainage. In the image, you can see how the drainage travels along the perimeter of the crawl space. This is where groundwater most often gets into the crawl space, so adding drainage here will help control the flow of groundwater away from the crawl space.

Sump Pump

Alongside the drainage system, our team also installed a sump pump for even more protection against groundwater. Looking at the image, you can see it placed in the corner of the crawl space. This area was chosen because it’s the lowest part of this particular crawl space. Groundwater naturally flows toward the lowest point where it will be captured and removed by the pump.

Vapor Barrier

Once the drainage system and sump pump were in place, our team installed a 3,000 square foot vapor barrier. With 120-mil thickness, the vapor barrier protects the crawl space from humid air and outdoor moisture. You can also see how the vapor barrier makes the crawl space look brighter and more inviting than before.

I tried to gird myself for what to expect when it comes to the bottom line, but I'd be lying if I said I was successful. I knew the crawlspace was in bad shape, but didn't know how bad it actually was until Justin Carter arrived to do the inspection. He took me through it step by step, and I never once doubted his or AFS's knowledge, professionalism, or capability. In the end, the process was smooth and easily accomplished, and no step ever felt like I was being rushed or pushed along. I felt like I was in good and earnest hangs. Yes, it's expensive, but good things cost money.

Travis S. was very thorough and professional. He took the time to explain what he was doing and why. He gave us tips on what we can do as homeowners to monitor and maintain our crawl space. He addressed our concerns and thoroughly inspected our encapsulated crawl space along with the exterior of our home. We were very impressed with his knowledge and professionalism. AFS should employ more people like Travis. We felt he went above and beyond what his job requires of him.

Highly recommend AFS Nashville. Jake came for our initial estimate. He took the time to explain everything in detail, which we really appreciated. He was not in a rush to give us an estimate and leave like the others. We accepted the estimate and the very next day we were placed on the schedule. The team arrived the planned start date and were here 3 days as expected. I cannot brag enough of the courteousness, attention to detail, and hard working men that were our crew. Adam, Selvin and Jesse were the best! Very hard working and Adam even talked to my neighbor about possibility of the equipment in her yard. I highly recommend AFS Nashville and this team. Many thanks for a job well done
