In Michigan, waterproofing your basement isn’t just a smart upgrade—it’s an absolute necessity. With heavy spring rains, snowy winters, and fluctuating temperatures, homes in Michigan face year-round moisture challenges that can threaten the health, safety, and value of your property.
At Mitten Made Basements, we believe every successful basement remodel starts with proper waterproofing. In this guide, we’ll break down everything Michigan homeowners need to know about protecting their basements from water damage—and ensuring a dry, comfortable space for years to come.
Why Basement Waterproofing Matters in Michigan
Michigan’s climate puts unique stress on homes:
- Freeze-thaw cycles create cracks in foundations
- Heavy rains lead to saturated soils and hydrostatic pressure
- Snowmelt can flood poorly drained basements
Without proper waterproofing, you risk:
- Mold and mildew growth
- Structural damage to your foundation
- Musty odors and poor indoor air quality
- Damage to furniture, flooring, and finished walls
A dry basement is the foundation of a safe, healthy home—and a smart investment.
Signs Your Basement Needs Waterproofing
Look for these warning signs:
- Water stains on walls or floors
- Damp, musty odors
- Efflorescence (white powdery deposits) on walls
- Cracked or bowed foundation walls
- Pooled water or visible seepage
- Increased humidity in the basement
If you notice any of these, it’s time to take action.
Interior Basement Waterproofing Solutions
1. Sump Pump Installation
- Sump pumps collect water from drainage systems and pump it safely away from your home.
- Battery backup systems ensure operation during power outages—a must during Michigan storms.
2. Interior French Drains
- Perforated pipes installed along the basement perimeter, beneath the floor.
- Channel groundwater into the sump pump pit.
3. Wall and Floor Sealants
- Waterproof paints and epoxy coatings create a moisture barrier.
- Best used as a secondary protection, not a standalone solution.
4. Dehumidifiers
- Maintain humidity levels below 50% to prevent mold.
- Essential in finished basements for air quality.
At Mitten Made Basements, we often combine multiple interior solutions to fully protect finished spaces.
Exterior Basement Waterproofing Solutions
1. Exterior Excavation and Waterproof Membranes
- Excavating around your foundation to apply waterproof coatings and membranes.
- Most effective—and most invasive—solution.
2. Drainage Tiles or French Drains
- Installed along the exterior footing to redirect water away before it can penetrate.
3. Grading and Landscaping Improvements
- Ensuring soil slopes away from your home’s foundation.
- Adding swales, berms, or dry wells for better runoff management.
4. Gutter and Downspout Maintenance
- Extend downspouts at least 6-10 feet away from the foundation.
- Keep gutters clean to prevent overflow.
Best Practices for Michigan Basement Waterproofing
- Address grading first: Sloping soil away from the foundation reduces groundwater pressure.
- Install a high-quality sump pump with backup power: Don’t rely on cheap pumps for critical protection.
- Seal and insulate walls carefully: Prevents hidden moisture issues behind finished drywall.
- Work with experienced local contractors: Michigan’s soil conditions vary by region—local expertise matters.
Common Basement Waterproofing Mistakes to Avoid
- Ignoring early warning signs: Small leaks often lead to big problems.
- Relying solely on interior sealants: Paint alone won’t stop groundwater intrusion.
- Poor sump pump installation: Improper sizing, no backup, or bad discharge lines spell trouble.
- DIY fixes without diagnosing the real problem: Waterproofing should start with a full professional assessment.
