Crawl Space Waterproofing
Crawl Space Waterproofing: Keep Water Out and Your Home Protected
If you’ve seen puddles on the dirt, noticed damp insulation, or smelled a musty odor coming up from your floors, water is getting into your crawl space. Whether it’s light moisture or standing water after every rain, it’s a problem that won’t solve itself.
Force Basements installs professional crawl space waterproofing systems tailored to your home. We use interior drainage, sump pumps, and vapor barriers to stop water at the source and keep it out for good. With our help, you can stop worrying about what’s happening underneath your home.
How Force Basements Performs Crawl Space Waterproofing
Our approach to crawl space waterproofing combines proven products and methods tailored to your home’s specific moisture problems.
1. Crawl Space Inspection
We start with a detailed inspection to identify moisture entry points, drainage problems, mold, rot, or structural concerns.
2. Moisture Source Identification
We determine whether the issue stems from ground moisture, wall leaks, poor drainage, foundation cracks, or condensation.
3. Water Removal & Drainage Installation
If water is present, we install:
Interior drainage channels
Sump pump systems
Downspout extensions
Grading recommendations for exterior runoff control
4. Vapor Barrier Installation
We install a durable, sealed vapor barrier to cover the crawl space floor and block ground moisture from rising into the space.
5. Dehumidifier Installation
We install a high-efficiency crawl space dehumidifier to control humidity and prevent future mold growth.
6. Optional Encapsulation
For maximum moisture protection, we may recommend crawl space encapsulation, which includes wall sealing, vent closure, and total air barrier creation.

FAQs About Crawl Space Waterproofing
Do I need waterproofing if my crawl space only gets damp during rain?
Yes — even occasional moisture can cause long-term damage. Prevention is much more affordable than repair.
Will a vapor barrier fix all moisture problems?
Not by itself. A vapor barrier blocks ground moisture, but drainage and dehumidification are often needed for full waterproofing.

Costs vary based on the size of your crawl space and severity of the moisture issue. We offer free inspections and customized solutions.
