Basement Repair Services
Basement Leaks & Flooding
Basements leak when the ground around the foundation is oversaturated with water. The resulting hydrostatic pressure pushes against your basement walls and the water will seep in. Jamison Waterproofing offers a full line of patented solutions to collect and divert groundwater away from your home eliminating all causes of basement leaks.
Mold, Humidity & Musty Odors
Basement environments are prone to have high levels of Relative Humidity (RH). When RH levels are at or above 60% conditions for mold growth and the resulting musty smells are created. Jamison Waterproofing offers powerful dehumidifiers and air filters to keep your basement and indoor air fresh and healthy.
Wall Cracks & Bowing
When the soil around the foundation is oversaturated, it exerts enormous amounts of pressure on the basement walls, causing them to crack and bow. Call Jamison Waterproofing at the first sign of foundation damage. We have effective leaking wall crack repair and bowing wall solutions to stabilize the walls and prevent further damage.
