In Boise, basement waterproofing, foundation crack repair, and below-grade drainage costs typically range from a few hundred dollars for minor crack repairs to several thousand for full waterproofing systems. Prices vary based on the size of your basement, the extent of water intrusion, accessibility, and the specific solutions required. Understanding these factors helps you plan and budget with confidence.

| Service | Price | Details |
|---|---|---|
| Basement Waterproofing | From $2,500 | Complete basement waterproofing for Boise homes: we trace the true water path (irrigation-season groundwater, foothill snowmelt runoff against downhill walls, seepage through silt and gravel, floor cracks) and build the right system: interior drain tile, sump pump, wall treatment and vapor barrier. |
| Interior Drain Tile System | From $50/linear ft | Interior perimeter drain tile installed beneath the slab edge: water is captured at the footing, channeled to a sump basin and pumped out. A proven year-round answer for valley homes where the water table climbs each irrigation season, installed in any season. |
| Exterior Basement Waterproofing | From $95/linear ft | Exterior excavation down to the footing with membrane or dimple-board waterproofing applied directly to the foundation wall, plus corrected grading and downspout extensions. The most thorough fix for walls that seep with irrigation and snowmelt, done once and built to last. |
| Foundation Waterproofing | From $3,500 | Waterproofing for brick, block, early poured and old stone foundations: parging and crack repair, membrane or crystalline treatments and drainage correction matched to your foundation type. Pre-1940 North End and East End homes get period-appropriate solutions. |
| Foundation Crack Repair | From $450 | Epoxy and polyurethane injection for non-structural foundation cracks, plus structural repair options for wider or shifting cracks where silty soil and foothill fill settle unevenly. Every crack is inspected and matched to the right repair method, not a one-size-fits-all patch. |
| Sump Pump Installation & Replacement | From $1,200 | New sump pits, pump replacement and discharge line correction: properly sized pumps, sealed basins, check valves and discharge routing that carries water well away from the house and keeps up with irrigation-season groundwater without burning out. |
| Bowing Wall Repair | From $600 | Carbon fiber straps, steel I-beams or wall anchors to stop and stabilize a bowing or leaning foundation wall, matched to the severity of the movement and your soil. Common where wet silt and frozen ground press on older block basement walls. |
| French Drain Installation | From $25/linear ft | Exterior drains installed along the foundation wall that intercept groundwater before it reaches your basement: properly graded gravel and pipe systems with fabric wrap, tied to daylight or a sump basin. A strong fit for Boise's foothill lots and irrigated yards. |
| Drain Tile Repair & Replacement | From $750 | Repair of collapsed, clogged or root-bound footing drains: many Boise homes from the 1940s-1960s still run on original clay tile that failed decades ago. Camera inspection, targeted excavation and modern PVC replacement restore drainage. |
| Vapor Barrier Installation | From $3/sq ft | Heavy-duty vapor barrier sheets installed across basement walls and slab to block ground moisture vapor from the soil: sealed seams, taped terminations, sump integration where needed and a drier, healthier lower level for your Treasure Valley home. |
| Basement Wall Sealing | From $1,500 | Surface preparation, efflorescence removal and penetrating or membrane sealers for damp basement walls. Honest guidance included: sealers solve minor dampness, not hydrostatic pressure, and we tell you which problem you actually have. |
| Battery Backup Sump Pumps | From $900 | Battery backup systems that keep pumping when a winter storm or summer outage knocks the power out, exactly when your sump pump matters most. Sized to your pit, with alarms and maintenance checks available. |
| Free Basement Inspection | Free inspection | Complete basement and foundation moisture inspection: walls, floor, cracks, sump system, grading and gutters checked, with photos and a written explanation of what needs fixing now, what can wait, and a straight answer if nothing is wrong. |
| Basement Mold Remediation | From $1,500 | Mold removal paired with the moisture fix that prevents its return: containment, treatment and remediation of affected surfaces, plus drainage or dehumidification for basements damp from irrigation-season groundwater. Musty smell diagnostics included. |
| Window Well Drainage & Repair | From $650 | Window well drains, liners and covers that stop wells from filling with irrigation overspray or snowmelt and dumping water against your foundation: a leak source homeowners rarely suspect and inspectors often miss. |
| Egress Window Installation | From $4,500 | Egress windows for finished basements: cut, framed, flashed and drained correctly so your new bedroom or living space stays dry. A natural pairing with waterproofing before a basement finish, popular on Boise daylight and walkout basements. |
