Waterproofing Services

Don’t wait! Reach out to us as soon as you notice moisture or foundation concerns. Common red flags include:

• Damp or sweating basement walls/floors (peeling paint or white, powdery efflorescence)
• Cracks in the foundation walls or slab—especially if they’re widening or leaking
• Musty, earthy odors or visible mold/high humidity in the basement
• Standing water around the foundation after rain or downspouts draining too close to the house
• Catching these early can prevent structural damage and more expensive repairs later.

Based on decades of field work, these are the red flags we tell homeowners to watch for:

• Mold or musty odors: Persistent smells or visible growth signal chronic moisture. Left alone, moisture and mold can damage wood framing and finishes and impact indoor air quality.
• Sagging or bouncy floors: Soft, uneven, or squeaky flooring can point to moisture-related wood deterioration or failing supports beneath the home.
• Water in the basement or crawl space: Puddles after rain, damp corners, or trickling at wall/floor joints often indicate hydrostatic pressure, settlement cracks, or inadequate drainage.
• Wood Root (including dry rot): Moisture allows fungi to break down load-bearing members, causing cracked or spongy beams/joists, gaps at baseboards, and structural risk. Wood rot is a serious issue that should be addressed immediately.
• Basement Condensation: Sweating walls, pipes, or windows may seem minor, but sustained humidity can lead to mold growth, wood decay, and rusted mechanicals if not controlled.

DIY fixes usually treat symptoms, not the source. A professional waterproofing contractor can diagnose the root cause (drainage, hydrostatic pressure, cracks) and design the right interior/exterior system including sump pumps, French drains, crack injection, and encapsulation, installed to code and backed by warranty. 

Since 1987, Helitech has delivered proven solutions and is the exclusive Midwest partner for the HydraDry high-flow drainage system. We offer free, no-obligation evaluations and a plan tailored to your home.

Costs vary based on where water is entering, the scope (linear feet/depth) of drainage, access conditions, the need for a sump/dehumidifier, and any structural or mold remediation. Helitech provides transparent, itemized pricing and flexible financing, 0% promotional plans, traditional installment loans, HELOCs, and full refinances, so you can choose a solution that fits your budget.

Interior waterproofing (interior drain tile, sump pump) relieves hydrostatic pressure and redirects water at the wall and floor joint, ideal for chronic seepage, finished basements, or when excavation isn’t practical. Exterior waterproofing (excavation, wall membrane, footing drains) blocks water before it enters, and works best for severe wall leaks or new builds. Helitech evaluates soil, grading, cracks, and access to recommend the right approach, often a targeted combination.
