Basement Waterproofing Davenport

Real Homes. Real Problems. Real Solutions.

If you’ve ever walked into your basement after a hard rain and smelled that damp, earthy odor or worse, found puddles–you’re not alone. Davenport homes, especially those built before the 1980s, deal with foundation seepage and water intrusion more often than most people realize.

At Tomlinson Cannon, we’ve spent generations helping Davenport homeowners get back their peace of mind with waterproofing solutions that actually work.

Basement Waterproofing Davenport

A Local Problem Needs a Local Expert

It’s not just about the rain; it’s about the soil, the slopes, the building practices, and how time wears on concrete. Many homes in Davenport were built on clay-rich soil that expands and contracts with moisture. That means more pressure on your basement walls and more opportunity for water to push its way in.

We see a lot of:

Water staining near wall-floor joints
Damp carpets and ruined drywall
Rusty appliances or musty smells
Sump pumps that can’t keep up
Horizontal wall cracks or bowing

Some problems are obvious. Others creep in slowly and quietly.. until it’s too late. That’s why it pays to get ahead of it.

What Makes Our Approach Different

We don’t believe in scare tactics, and we don’t rely on one-size-fits-all systems. When you reach out to us, here’s what you can expect:

A detailed, free inspection from a trained professional
A clear explanation of what’s happening and why
A waterproofing solution tailored to your home
A clean, respectful installation process
A lifetime guarantee that stays with the house

That’s what real service looks like.

Our Most Trusted Waterproofing Solutions

Depending on your basement and the source of the issue, we may recommend one or more of the following:

Interior Drainage Systems

These systems collect water that enters through the foundation and direct it to a reliable sump pump. It’s discreet, effective, and long-lasting.

Wall Stabilization and Crack Repair

Some water comes in through structural weaknesses. We fix that with crack sealing, injections, or bracing if necessary restoring integrity and stopping leaks.
