Basement waterproofing is particularly important because this area of your house is below ground level and therefore more susceptible to water damage.

We help clients throughout Tri-State area keep their homes safe and sealed off from water.

Keeping your basement dry is an extremely high priority to you as a homeowner. Your basement is below ground level, so waterproofing and drainage consideration are especially important, as groundwater is likely to build up in the soil and cause major structural damage to foundation walls, which can lead to mold growth, decay, and many other moisture related problems. Like any other damaging effect prevention is better than repair. LJS can apply waterproofing techniques to prevent water damage to your basement. Waterproofing your basement can prevent your family from being exposed to harmful mold, mildew, and fungus that can cause numerous allergies or respiratory problems.
