Sump Pumps Photo Album: Crawl Space Repair in Nashville, TN

Claudette in Nashville, TN, contacted Frontier after the existing sump pump in her crawl space failed and stopped removing water from the home. During the inspection, the design specialist found elevated moisture levels in the crawl space, including a relative humidity reading of 63%, which is above the recommended threshold where mold growth and pests can become more likely. To restore proper drainage, the Frontier team replaced the failed system with a TripleSafe battery backup sump pump designed to continue protecting the home even during heavy rains or power outages. To help protect the crawl space long term, the team encapsulated the space and installed a SaniDry Sedona dehumidifier to control humidity and create a healthier, drier environment beneath the home.

Failed Sump Pump

The existing sump pump was not removing water from the crawl space, leading to high humidity levels.

Relative Humidity Reading

Frontier's design specialists do a relative humidity reading in every crawl space. An RH reading over 60% indicates high moisture that can facilitate mold growth.

Falling Insulation

Insulation material absorbs humidity in the air, becomes heavy, and falls. The purpose of the insulation is compromised, and it is hazardous to service the space.

Sealing Vents

Open vents allow humid air to enter the crawl space and create high moisture conditions and condensation. Frontier seals the vents with SilverGlo panels and RimTite insulation to create a conditioned space.

Drainage Matting

Drainage matting is installed underneath CleanSpace liner to allow lateral water movement under the encapsulation. The material is custom-laid for each home.

Full Encapsulation

CleanSpace liner covers the floor, walls, and piers of the crawl space, preventing moisture intrusion from all sides.

Water Heater

The encapsulation is placed over the base of the water heater so any leakage can flow towards the sump pump.

IceGuard

Every drainage line installed by Frontier includes an IceGuard discharge fitting, which allows water to escape the system if the discharge line becomes blocked further down the pipe, such as during freezing temperatures or clogs.
