Have these ready before contractors call
Waterproofing quotes depend on the same few facts. Knowing them helps contractors bring the right answer on the first visit.
- When it happens
- After heavy rain, during spring snowmelt, all year, or only in humid summer weather.
- Where it shows
- At the floor-wall joint, through a crack, up through the floor, or as damp walls all over.
- Wall type
- Poured concrete, concrete block or stone. Block walls can hold water in their cores.
- What is outside
- Where downspouts empty, whether the ground slopes toward the house, window wells.
- Sump pump
- Whether you have one, how old it is, and whether it runs often.
- Finished space
- Drywall, carpet or framing that would need to come out for interior work.
Questions people ask
How much does basement waterproofing cost in Green Bay?
National cost guides put interior waterproofing for a 750–1,000 sq ft basement at about $4,500–$10,000 and exterior waterproofing at $10,000–$15,000, or roughly $6–$15 per square foot overall. Single fixes cost less: a sump pump runs $600–$2,500 installed and crack injection $250–$800 per crack. Use the cost estimator for your basement, then compare local quotes.
Interior or exterior waterproofing: which is better?
Interior drain tile and a sump manage water that gets past the wall and is usually cheaper and less disruptive. Exterior waterproofing keeps water off the wall itself but means digging down to the footing. Many homes only need one; a contractor can tell from where and when the water appears.
Is my wet basement a leak or condensation?
Tape a piece of aluminum foil tightly to the damp wall for a day or two. Moisture on the room side means condensation from humid air; moisture behind the foil means water coming through the wall. This test comes from University of Minnesota Extension guidance. Try the wet basement checker.
Can gutters and grading fix it?
Often they help a lot. Extension guidance says much basement seepage comes from surface runoff: missing gutters, short downspouts and ground sloping toward the house. It recommends the ground fall at least 6 inches within 10 feet of the foundation. These are worth fixing before paying for drain tile.
What humidity should a basement be?
The EPA advises keeping indoor humidity below 60 percent, ideally 30–50 percent. A cheap hygrometer will tell you where you are.
Do I need to remove finished walls?
Interior drain tile and crack repair need access to the bottom of the walls and the floor edge, so some drywall and flooring usually comes out. Exterior work can leave the inside alone. Mention finished areas in your request so quotes include it.
