Permanent Water Intrusion Solutions

EVALUATE a water intrusion risk before it’s too late! Is your home 40 years old or older? Do you have a basement? Is your home on a hill? Have you or your neighbors recently changed a grade around your house? Are there any new apartments or housing developments built within last three years in your area? Are the gutters and downspouts functioning well? Have you noticed some cracks or settlements in the house foundations or steam walls? If you answered yes to any of these questions, your home could be at risk of water intrusion – with devastating results.


The best protection against such a disaster is PREVENTION! Contact us for consultation!

Has water flooded your home? This is a true emergency and must be addressed at once! Don’t leave wet carpets or floors unattended. Water damaged areas must be dried within 24 to 48 hours to prevent mold growth. Moreover, once water has eroded a path into your home it is unstoppable. Reoccurring flooding will occur and the resultant mold and fungi growth are now your number one concern. If you want to save a lot of money and time, don’t call “Water Damage Restoration Services”. They only suck up water and dry the area temporarily leaving you with a hefty bill (sometimes 5-digit one) and still leaving you with a headache of unresolved problems.  Run to a local hardware store or rental place and get blowers and humidifiers. This would save you money that you will need to use for installing a permanent solution.


Don’t panic! Contact us IMMEDIATELY!

The key to mold control is moisture control. Wet Basement Services combines simple water redirection with state-of-the-art drainages and membranes to control water intrusions permanently. We have a 100% success rate in extreme water abatement. We’ve helped clients who suffered for decades from winter flooding of their basements. Our system desaturates liquefied soils under your house footings and basement floor slab. This solution is different than most drainage systems of our local competitors, which act only like a “band aid”, and not address real sources of the issue you have. We will be happy to elaborate on it when we meet together when you schedule your Free Inspection.


Our systems will cure your headache PERMANENTLY!

Lifetime transferable warranty on our interior basement waterproofing services.

Interior Waterproofing Service

Our interior waterproofing system, uses membranes and French drains placed along foundation footings and basement steam walls, thereby encapsulating the basement from the outside. We place new drainage pipes at the side of the footings and cover them with P-gravel and drainage fabric, which redirect water to the exterior by using gravity or a sump pump. This is a highly effective and cost-efficient way to control water intrusions. Interior waterproofing can be done faster than exterior waterproofing.

Exterior Waterproofing Service

Our exterior waterproofing consists of excavating foundation walls to the bottom of the footings. Once the area is excavated, the walls are covered with exterior membranes, like Delta or Mira drains, which expand drainage areas to all layers of the soil profile. In addition, we may seal the dry walls with waterproofing solution. And at the side of the footings, we install new drainage pipes covered with P-gravel and drainage fabric.
