Professional Basement Waterproofing Across the Quad Cities – Tomlinson Cannon’s Proven Protection for IA & IL Homes

Living in the Quad Cities means enjoying river views, historic neighborhoods, and tight-knit communities–but it also means dealing with frequent rain, high water tables, and flood-prone zones, especially near the Mississippi. For many homeowners in Davenport, Bettendorf, Moline, and Rock Island, basement moisture is a recurring issue–and one that can quietly damage your home if ignored. That’s why basement waterproofing in the Quad Cities isn’t just a precaution–it’s a must. Whether you're seeing damp walls, musty smells, or full-blown flooding, Tomlinson Cannon offers solutions that are designed to work with our local soils, foundations, and storm patterns.

Why So Many Quad Cities Homes Deal With Basement Water Problems

1. Floodplain Realities

Neighborhoods near the Rock River and Mississippi River, especially older homes in Rock Island and Moline, were built long before modern drainage planning. During spring thaw or heavy storms, those basements take on water fast.

2. Aging Foundations

A large portion of the housing stock across the Quad Cities was built before the 1970s. Many have cracked masonry, deteriorated footings, or outdated drainage systems. Water intrusion often starts slow and turns costly.

3. High Water Table & Poor Grading

Some areas especially near Bettendorf’s valleys or lower Davenport–sit over a high water table. Pair that with flat yards and aging downspouts, and you’ve got water pushing against your foundation 24/7.

Signs You Might Need Basement Waterproofing

If you live in the Quad Cities and are noticing any of the following, it’s time to take action:

• White chalky buildup (efflorescence) on your basement walls
• Warped or musty-smelling carpet and furniture
• Pooled water after a storm
• Paint bubbling or drywall deterioration
• Mold growth or poor air quality upstairs

These aren’t just cosmetic issues–they’re symptoms of a bigger waterproofing failure.

Tomlinson Cannon’s Basement Waterproofing Solutions for the Quad Cities

We’ve been protecting Iowa and Illinois homes since 1948. Every basement waterproofing plan we design is tailored to your structure, soil, and water sources. Here’s what our systems typically include:

1. Interior Drain Tile Systems

Placed along the inside perimeter of your basement floor, this system collects water before it enters your space and diverts it to a sump pump.

2. High-Capacity Sump Pumps

Essential in areas with rising groundwater, our pumps evacuate water even during heavy storms and we always recommend a backup pump or battery system for peace of mind.

3. Wall Sealants & Vapor Barriers

To stop water seepage and control humidity, we seal walls with breathable coatings and install vapor barriers where necessary.

4. Grading & Exterior Recommendations

While our focus is inside your basement, we often suggest gutter extensions, downspout redirection, or grading adjustments to prevent surface water from reaching your home in the first place.

Real Solutions. Real Results. Right Here in the Quad Cities.

A Davenport homeowner recently contacted us after multiple floods destroyed her storage and left mold on the basement walls. We installed an interior drain system, new sump pump with backup, and sealed vulnerable wall areas. Six months later, her basement stayed completely dry even during a spring storm that dumped over 3 inches of rain. Our systems are built to withstand the Midwest’s worst weather and come with warranties you can count on.
