A proven, methodical approach refined over 20+ years of professional installation.
We inspect your basement to identify moisture sources, entry points, soil conditions, and drainage issues — determining the most effective waterproofing approach.
Based on the assessment, we recommend the right combination of waterproofing methods — membranes, coatings, drainage, and insulation — for your specific situation.
Our crew applies waterproofing membranes, sealant coatings, and/or drainage systems to create a comprehensive moisture barrier for your basement.
We verify the waterproofing system's integrity and, if desired, install insulation for an energy-efficient, comfortable finished basement.
Denver basements face a unique combination of moisture threats: expansive bentonite clay soils that swell when wet and push against foundation walls, spring snowmelt that saturates the ground around your home, and occasional heavy rainstorms that overwhelm drainage systems. These forces can drive moisture through foundation walls and floor slabs, causing water staining, efflorescence, mold growth, and in severe cases, standing water and structural damage. Sky Insulation provides basement waterproofing solutions that address both the symptoms and the root causes of moisture intrusion. Our approach combines waterproofing membranes and coatings with proper drainage and insulation to create a comprehensive moisture management system. For new construction, we apply exterior waterproofing membranes before backfill. For existing homes, we offer interior waterproofing solutions that manage moisture without excavation. A dry basement isn't just about preventing water damage — it's about creating usable living space and protecting your home's value. When combined with proper insulation, a waterproofed basement adds comfortable, energy-efficient square footage to your Denver home.

Comprehensive waterproofing keeps your basement dry through Denver's spring snowmelt, summer storms, and seasonal ground moisture fluctuations.
Waterproofing prevents moisture-related damage to foundation walls, floor slabs, and framing — preserving your home's structural integrity.
A dry basement eliminates the conditions that allow mold and mildew to grow, improving indoor air quality throughout your home.
A waterproofed, insulated basement adds comfortable, usable square footage to your home — increasing both livability and property value.






Denver's expansive clay soils (bentonite) swell when saturated, pushing moisture against foundation walls. Spring snowmelt, heavy rain events, and poor exterior drainage compound the problem. Even well-built homes can develop basement moisture issues over time.
Exterior waterproofing involves applying membranes to the outside of foundation walls (requires excavation) and is ideal for new construction. Interior waterproofing manages moisture from inside the basement using coatings, drainage channels, and sump systems — more practical for existing homes.
Interior waterproofing solutions can be installed in finished basements with targeted removal of finishes near problem areas. For comprehensive waterproofing of a finished basement, some drywall removal along the foundation walls may be necessary.
Waterproofing addresses the moisture source that mold needs to grow. Once the basement is dry, existing mold can be treated and the conditions that caused it are eliminated. We recommend combining waterproofing with mold remediation for the best results.
