Our Services
Water in your basement is not just an inconvenience. It damages finishes, promotes mold growth, and signals deeper issues with drainage or your foundation. Our specialists install interior and exterior waterproofing systems designed to keep your basement dry for the long term.
How It Works
Where is the water coming from? How often does it happen? After rain, during snowmelt, or all the time? These details help us match you with the right specialist.
We connect you with a licensed professional who specializes in the type of waterproofing your home needs, whether interior drainage, exterior membrane, or a combination.
Your specialist evaluates your basement, identifies the source of the water, and recommends a solution with a clear scope and quote.
Basement waterproofing falls into two broad categories. Interior systems include weeping tile installed along the perimeter of your basement floor, connected to a sump pump that discharges water away from your home. Exterior systems involve excavating around the foundation to apply waterproof membranes and install drainage tile at the footing level. Many homes benefit from a combination of both approaches, along with proper grading and downspout management.
If you see water pooling on your basement floor after rain, white mineral deposits (efflorescence) on your walls, musty odors, or visible mold, your basement likely has a moisture problem. Damp spots that appear during spring thaw or heavy rain are especially common in clay-heavy soil regions. Even if you do not see standing water, persistent humidity above 60% in your basement can cause long-term damage.
Interior waterproofing typically takes two to four days depending on basement size. The process involves cutting a narrow trench around the perimeter, installing drainage pipe, placing a sump pit and pump, and pouring new concrete over the system. Exterior work takes longer due to excavation but provides the most comprehensive protection. Most waterproofing systems come with a transferable warranty.
Common Questions
Interior waterproofing manages water that has already entered your foundation walls by collecting it in a drainage channel and pumping it out. Exterior waterproofing stops water before it reaches the wall by applying a membrane and drainage system on the outside of your foundation. Exterior is more comprehensive but involves excavation.
A properly installed interior drainage system with a quality sump pump typically lasts 25 years or more. Exterior membranes can last the lifetime of the home. Sump pumps themselves have a lifespan of 7 to 10 years and should be tested regularly.
Common signs include water on the floor after rain, damp or wet walls, white crusty deposits on concrete (efflorescence), musty odors, mold growth, and peeling paint or bubbling drywall in your basement. Even minor dampness can indicate a larger drainage issue.
Interior waterproofing with a drainage system and sump pump typically ranges from $5,000 to $15,000 depending on basement size and complexity. Exterior waterproofing costs more due to excavation. Your specialist will provide a detailed quote after assessing your specific situation.
