Crawl Space Dry Rot Damage in Richmond, KY
Challenge
The homeowners noticed sagging floors in a specific section on the first level of their home and were concerned about structural safety. During the inspection, our team discovered that part of the wooden framing in the crawl space had succumbed to wood rot, compromising stability and making the floors unsafe to walk on. This rot likely developed over time due to high moisture levels and persistent groundwater in the crawl space, which created ideal conditions for fungal decay in the wood. We recommended replacing all the rotted wood and fully encapsulating the crawl space to protect the remaining framing and prevent further issues. The homeowners appreciated the comprehensive approach, requested a full quote, and quickly approved the work.
Solution
We began by removing all old, water-damaged fiberglass insulation from the ceiling and clearing debris from the crawl space, leaving the area clean and accessible. Because the home was prone to groundwater, we installed a full waterproofing system. Trenches were dug along the perimeter, and perforated pipes were placed and backfilled with gravel to channel water to a SmartSump sump pump at the lowest point of the crawl space.
Once the waterproofing was complete, we repaired the damaged framing. This included sistering 400 feet of rim joists, 32 feet of band boards and sill plates, and replacing 45 feet of the three main beams to restore structural strength.
After the framing repairs, we treated all exposed wood and concrete surfaces with Anabec cleanser. The remaining wood, which was still structurally sound, was ideal for surface treatment to help prevent future wood rot. Anabec is environmentally safe and doesn’t rely on harsh chemicals like bleach. It helps lift surface mold, dirt, and organic residue, leaving the wood cleaner and more stable. While it doesn’t penetrate deeply enough to eliminate mold inside porous wood, when paired with full encapsulation, proper drainage, and humidity control, it reduces the risk of rot returning and helps protect the home’s framing long-term.
Next, we laid down dimpled drainage matting across the floor and simultaneously installed SilverGlo insulation panels along the walls. The dimples in the matting channel water toward the sump pump while cushioning the floor for safer access. SilverGlo panels are made of an inorganic material (graphite) so that they can't grow mold or hold moisture, adding a layer of protection that helps keep floors in the home warm during winter months.
We then installed the CleanSpace liner over the drainage matting and up the walls over the SilverGlo panels. The seams were carefully taped and secured to create a continuous moisture barrier.
To control humidity, a SaniDry Sedona dehumidifier was installed near the sump pump. It removes up to 99 liters of moisture per day and operates automatically to maintain optimal conditions.
Finally, we installed a discharge line for the sump pump, including a hidden LawnScape outlet for aesthetics and an IceGuard spout to prevent blockages in freezing conditions. All vents were sealed and an EverLast crawl space door was installed, completing a fully protected and encapsulated space.
The homeowners immediately noticed improved conditions. The crawl space is now dry, safe, and structurally secure, with a reduced risk of wood rot, pests, and moisture-related damage.
