| Service | Price | Details |
|---|---|---|
| Basement Waterproofing | From $2,500 | Complete basement waterproofing for Nashville homes: we trace the true water path (hillside runoff against downhill walls, wall seepage through red clay over limestone, floor cracks, high spring water table) 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 hillside Nashville homes where rain-fed groundwater rises against the walls, 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 after Nashville storms, done once and built to last. |
| Foundation Waterproofing | From $3,500 | Waterproofing for block, poured and old stone foundations: parging and crack repair, membrane or crystalline treatments and drainage correction matched to your foundation type. Pre-1940 East Nashville and Germantown homes with stone or block walls 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 thin clay soil over limestone settles 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 Nashville's heavy spring and thunderstorm rain 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 saturated hillside clay presses 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 Nashville's sloped lots where runoff arrives from uphill. |
| Drain Tile Repair & Replacement | From $750 | Repair of collapsed, clogged or root-bound footing drains: many Nashville 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 Middle Tennessee 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 Nashville storm 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 Nashville's humid summers. Musty smell diagnostics included. |
| Window Well Drainage & Repair | From $650 | Window well drains, liners and covers that stop wells from filling and dumping water against your foundation: a leak source homeowners rarely suspect and inspectors often miss, especially on hillside homes. |
| 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 Nashville walkout and hillside homes. |
