J L Construction LLC: Waterproofing Service

Waterproofing is needed when you have water seepage, dampness, mold, mildew, white chalky residue or musty smells in your home and/or basement. We also carry Mold / Mildew retardant products.
Exterior Waterproofing consist of excavation of dirt from your home or business foundation and installation of a total drainage system. JL’s waterproofing services includes drainage, brick sealing, concrete sealing, and grading. JL's Interior Waterproofing includes sump pump installation and wall/ ceiling sealing.
Choosing Water Control or Waterproofing is a decision you will need to make. Water Control aims to direct the drainage inside your basement to a sump pump to control the water that is entering. While waterproofing is accomplished only by exterior excavation to the bottom of the foundation, installing proper drainage and treating the walls to prevent water from entering.
