What our customers say

Read the newest on Google

“When Champion came to give an estimate for a fix we were told there was not enough significant movement to warrant piering at this time. Instead of taking on the expensive job they were honest with their opinion of our concern. Champion is a company with integrity.”

Meredith D. on Angi, wall anchors, March 2019

“He replaced a main sump pump in a short amount of time and made sure that it was perfect. Champion Water Proofing is the best at what they do.”

Dal N. on Angi, January 2026

“I am very detail oriented and picky, and have high standards with regards to work done around the house. And the quality of work was an A+.”

Five basement problems we fix, and the signs to look for

Every house is different, so it starts with a free inspection and an honest opinion about what yours needs.

Standing water across a basement floor along a painted block wall

Wet or leaking basement

Water finds its way in through cracks and the joint where the wall meets the floor. We install systems that move it away from your foundation and seal the cracks and joints.

  • White, chalky powder on the walls
  • Peeling paint, soft wood, rusting metal
  • A musty smell that won't leave

How water gets into a Western PA basement, and how we stop it

How water gets in

  1. Rain and snowmelt soak the soil around your foundation, storm after storm.
  2. Wet soil pushes on the wall. Over years, that pressure can crack a block wall or bow it inward.
  3. Water finds the weak spots: cracks, and the joint where the wall meets the floor.
  4. Damp air does the rest: condensation, a musty smell, and mold on the walls.

How we stop it

  1. Drainage along the footing collects the water before it reaches your floor.
  2. A sump pump carries it out and away from the house.
  3. Cracks and joints are sealed.
  4. Bowing walls are braced with engineer-approved carbon fiber straps, 4-inch steel I-beams or wall anchors.

Your free inspection decides which of these your house needs. Sometimes the honest answer is none of them yet.

Questions homeowners ask before they call

More answers on Problems we fix

Why does my basement leak after heavy rain?

When the ground around your house is soaked, the water in the soil presses against the foundation and looks for a way in. It usually finds one at cracks in the wall or at the joint where the wall meets the floor. Poor drainage around the house makes it worse.

Is the inspection really free?

Yes. Our inspections are free, pressure-free and come with no obligation. We look at what's going on, tell you what we see and what we'd do about it, and the decision is yours.

Is a horizontal crack in my basement wall serious?

It can be. A horizontal crack, or a wall that has started to lean inward, is a sign the soil is pushing on it. It's worth having looked at early, because a wall caught early is usually a smaller repair than one left to move.

Will you tell me if I don't need the big repair?

Yes. We give honest assessments, and our customers say so. One wrote that we told her there wasn't enough movement to warrant piering, instead of selling her the expensive job.

How much does basement waterproofing cost?

It depends on the house: how much wall is involved, where the water comes in, and whether there's a crack or a bowing wall to deal with too. That's why we start with a free inspection and give you a quote for your basement, not a guess.

Does the warranty transfer if I sell my house?

Yes. Our waterproofing comes with a transferable lifetime warranty. If you sell your home, the warranty goes with it.

What is crawl space encapsulation?

We cover the crawl space walls and dirt floor with a professional vapor barrier, and add ventilation (like a Humidex system) to keep the air moving. Homeowners notice better air and less mold, mildew, pests and wood rot.
