Basement Waterproofing Information & Facts

Why does my basement leak?

The most common cause of basement leakage is rain water leaking through below-grade walls or the basement floor. The saturation of the ground will cause ground water to rise and create a false water table. As the water creates upward pressure (hydrostatic pressure), the water will follow the path of least resistance and rush toward openings into the basement.

Are wet basements a common problem?

Yes. Home inspectors estimate that 98% of all basements will leak at some point during their life. Block foundations are especially vulnerable with an 80% – 90% chance of leakage within the first 20 years.

My basement has minor leakage after heavy rains. Does my Basement need Waterproofing?

Have a professional waterproofer inspect your basement to determine the cause of the leak and make recommendations to correct your specific problem before it becomes worse. The water that you don’t see is what causes serious foundation problems.

We have owned our home for several years and our basement has never leaked and one day it began to leak. Why did this happen?

Problems develop over time. As the home settles, walls crack, protective coatings applied to the exterior biodegrades and drainage systems fill up with silt. All of these problems can lead to leakage in the basement.

When should I consider Waterproofing my Basement?

At the first sign of water intrusion, you should have a professional inspection. Homeowners delay waterproofing and are unaware of the destructive effect and damage water penetrating the foundation and home can cause. Waterproofing your basement will increase the market value of your home and provide additional living and storage space. A dry basement will provide you with a healthier environment and peace of mind.

Should I be concerned with mold?

Yes. Mold growth is a direct result of water or moisture problems. Mold growth can begin within 24 – 48 hours and is a potential health hazard. Mold can also lead to property damage and loss of property value. Find a qualified and experienced waterproofer that is certified in mold remediation. Using an uncertified waterproofer/mold remediator can lead to mold contamination throughout your entire home.

How do I choose the right Waterproofing Contractor?

– Check references and testimonials from previous customers.

– Contact the Better Business Bureau and check complaint history.

– Check the license for both home improvement contractors and their salesperson(s). In Maryland, both are required to be licensed and in addition, all personnel must pass a written exam and background check. Contact the Maryland Home Improvement Commission (MHIC) at 410-230-6309. The MHIC can provide valid license and complaint information.

– Always get a written contract. Read the contract carefully and be sure you receive a copy of the contract upon signing.
