Your Des Moines home deserves a foundation that's dry, healthy, and built to last. We connect homeowners with local experts who provide the engineering and commitment needed to eliminate moisture problems for good.
Crawl Space Encapsulation
The ultimate solution for Central Iowa foundation protection. Experts transform damp, dark crawl spaces into clean, dry, conditioned areas that improve indoor air quality and increase property value.
Iowa's high water table and humid summers turn open crawl spaces into mold factories, rotting floor joists and inviting pests into the home's living area.
Specialists install 20-mil antimicrobial liners that are mechanically fastened and permanently sealed, creating a durable barrier between the home and the raw earth.
Vapor Barrier Systems
Essential moisture protection designed specifically for the unique humidity challenges and heavy clay soil conditions of the Des Moines metro area.
Standard thin plastic liners used by many local builders tear easily, bunch up, and fail to stop 'earth-smells' and radon gases from infiltrating the home.
Experienced contractors install heavy-duty, multi-layer reinforced polyethylene barriers custom-tailored to every corner for a 100% monolithic seal.
Crawl Space Insulation
Upgrade from failing fiberglass to moisture-resistant rigid foam boards. These solutions keep Des Moines homes cozy and floors warm even during sub-zero Iowa winters.
Old fiberglass 'batts' absorb Iowa humidity, sag under weight, and become a breeding ground for rodents while leaving pipes exposed to freezing.
Specialists install closed-cell rigid foam insulation directly to foundation walls, creating a continuous thermal break that keeps heat in and cold air out.
Moisture Control Systems
Precision humidity control engineered for the Iowa climate. Industrial-grade systems keep crawl space air dry, protecting health and home structure.
Even with a barrier, Des Moines' summer humidity can reach 90%+. This moisture condenses on cold surfaces, fueling mold growth and warping hardwood flooring.
Experts integrate high-capacity, self-draining dehumidifiers that automatically maintain humidity levels below 55%, filtering the air.
Crawl Space Repair
Structural restoration for sagging or bouncy floors. Integrity is restored to the foundation using heavy-duty, engineered steel support jacks.
Excessive moisture weakens wood beams over time, leading to bouncy floors, sticking doors, and visible cracks in upstairs drywall.
Adjustable steel piers and beam reinforcement transfer the weight of the home to stable soil, leveling floors and stopping further settlement.
Crawl Space Inspections
Expert 25-point crawl space evaluations for Des Moines homeowners. Professional assessments identify issues before they become major expenses.
Most homeowners never enter their crawl space, allowing leaks, mold, and structural rot to go unnoticed for years until they become catastrophic.
Detailed visual and digital inspections using moisture meters and thermal imaging provide a clear roadmap for long-term health and safety.
