Exterior & Below-Grade Waterproofing in janesville
What exterior waterproofing involves
Exterior and below-grade waterproofing stops water at the foundation wall instead of managing it after it gets inside. A crew digs down to the footing, cleans and repairs the wall, then applies a membrane or coating. Most jobs also add drainage: new drain tile at the footing, gravel backfill, and a dimpled protection board. Janesville's clay-heavy soils, spring thaw and freeze-thaw cycles put steady pressure on block and poured walls, so cracks and failed coatings tend to show up as damp basements, efflorescence or bowed walls.
What to look for
- A written scope that names the wall depth, membrane type and drain tile, not just "waterproofing."
- Repair of cracks and tie holes before coating.
- A plan for discharging water well away from the house, including downspouts and grading.
- Warranty terms in writing, and whether they transfer to a new owner.
- Proof of insurance and local references.

Call a Waterproofing ProviderCommon questions about exterior & below-grade waterproofing
- How much does exterior waterproofing cost?
- Costs vary widely with wall length and depth. Many full exterior jobs run from roughly $80 to $250 per linear foot, so a typical home can land between $8,000 and $30,000 or more. Spot repairs on a single crack or section cost far less. Get at least three written quotes.
- How often does a foundation need waterproofing?
- A quality membrane and drain tile system can last 20 to 30 years or more. Basic damp-proofing coatings fade sooner. You usually act when you see seepage, wall cracks, mold or efflorescence, not on a fixed schedule.
- What should I expect during an exterior waterproofing job?
- Expect excavation along the foundation, which disturbs landscaping, patios or steps. Crews repair the wall, apply the membrane, install drain tile and backfill. Most homes take several days to a week, depending on weather and access.
- How do I judge a contractor's quality?
- Ask for a detailed written scope, a transferable warranty, proof of insurance and recent local references. Be cautious of quotes that skip drainage or recommend digging the whole house when only one wall leaks.
