Water in a basement is more than an inconvenience; it threatens structural integrity, indoor air quality, and property value. Homeowners searching “cost to seal a basement” want a clear, actionable number. At CountBricks, we turn that number into a data-backed plan by combining real-time material pricing, AI-driven labor calculations, and voice-activated blueprint takeoffs. Let’s break down what goes into the final figure and how CountBricks keeps every dollar accounted for.
For most single-family homes, CountBricks sees interior sealing projects land between $3 and $9 per square foot, while exterior waterproofing ranges from $8 to $20 per square foot. Those broad ranges reflect five cost drivers every homeowner should understand.
• Hairline crack injection only? Expect $400–$800.
• Full interior membrane with sump install? Plan on $3,000–$7,500.
• Exterior excavation, French drain, and dampproof coating? $12,000–$25,000 is typical for a 1,000 sq ft footprint.
Block foundations absorb more moisture than poured concrete, often requiring additional epoxy injections or membrane layers. CountBricks automatically flags block walls in your blueprint and adjusts material counts in seconds.
Tight lot lines or mature landscaping can double excavation labor. Our AI voice estimator asks about site obstacles during the call, so surprises never reach your final invoice.
• Basic acrylic sealer costs as little as $0.25 per sq ft.
• Crystalline waterproofing compounds average $1.20 per sq ft.
• High-grade elastomeric membranes run $2.50+ per sq ft but deliver 20-year warranties.
Some municipalities now require radon mitigation or drain tile inspection. CountBricks updates permit fees weekly inside the platform, ensuring your estimate complies with the latest regulations.

The Donovan family faced recurring puddles every spring. Using CountBricks’ AI takeoff, we projected 86 linear ft of wall requiring membrane, sump, and drain tile. The final cost to seal their basement: $14,850—8% under the regional average for similar scope. Post-project humidity readings dropped from 72% to 44%, and the Donovans listed their newly finished basement as a bonus room in a successful home appraisal.
• Schedule work in late summer when groundwater is lowest.
• Combine sealing with other foundation repairs to save on mobilization fees.
• Opt for lifetime warranty membranes—higher initial cost, but transferable coverage boosts resale value.
• Keep gutters and grading maintained; prevention reduces future sealing scope.
