Comprehensive Basement Waterproofing Services in Marietta-Alderwood

Mr Basement Waterproofing offers a full suite of services designed to completely waterproof your Marietta-Alderwood, WA basement. Whether you're dealing with minor seepage or major flooding, our solutions are customized to your home's specific needs.

Interior Drainage Systems

Install our patented WaterGuard system along basement walls to capture water before it enters your living space. This sub-floor drain channels water to a high-capacity sump pump, preventing hydrostatic pressure buildup. Ideal for Marietta-Alderwood homes with high water tables.

Sump Pump Installation & Repair

Upgrade to battery backup and ultra sump pumps that operate during power outages common in WA hurricanes. We service all brands and provide annual maintenance plans.

Exterior Waterproofing

Dig and apply heavy-duty membranes, dimple boards, and French drains around your foundation perimeter. The gold standard for preventing water from reaching your basement walls.

Foundation Crack Repair

Inject polyurethane or epoxy into cracks to stop leaks permanently. Our process includes carbon fiber reinforcement for structural integrity.

Mold Remediation & Dehumidification

Remove mold safely and install SaniDry dehumidifiers to keep humidity below 55%, preventing regrowth in Marietta-Alderwood, WA's muggy air.

Crawl Space Waterproofing

Encapsulate with CleanSpace liner, insulate, and add drainage to convert damp crawl spaces into conditioned storage.

Each service is backed by detailed engineering reports and 3D modeling to show exactly how we'll protect your home. For basement waterproofing Miami Florida, we also specialize in flood venting and backwater valve installations to meet WA flood codes. Our process minimizes disruption – most interior jobs complete in 2-3 days.

Why Interior vs. Exterior Waterproofing?

Interior systems are faster and cheaper for existing homes, capturing water inside the foundation footprint. Exterior is preventive for new builds or severe issues. In Marietta-Alderwood, where limestone bedrock causes sinkholes, we often combine both for ultimate protection. Costs range from $5,000 for basic sump upgrades to $20,000+ for full perimeter digs, with financing available.
