| Service | Price | Details |
|---|---|---|
| Basement Waterproofing | From $2,500 | Complete waterproofing for Memphis homes with below-grade space: we trace the true water path (loess silt that holds water, a high water table, wall seepage after downpours, 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 answer for the Memphis homes that do have basements or sunken lower levels, where a high water table pushes up after heavy rain. |
| 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 Mid-South downpours, done once and built to last. |
| Foundation Waterproofing | From $3,500 | Waterproofing for block, poured and old brick foundations: parging and crack repair, membrane or crystalline treatments and drainage correction matched to your foundation type. Pre-1940 Midtown and Cooper-Young homes with brick 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 silty loess and clay pockets move with wet and dry seasons. 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 Memphis thunderstorm downpours 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. Seen where saturated loess and clay press on older block walls. |
| French Drain Installation | From $25/linear ft | Exterior drains installed along the foundation wall that intercept groundwater before it reaches your foundation: properly graded gravel and pipe systems with fabric wrap, tied to daylight or a sump basin. A strong fit for flat Memphis lots where water has nowhere to go. |
| Drain Tile Repair & Replacement | From $750 | Repair of collapsed, clogged or root-bound footing drains: many Memphis homes from the 1930s-1960s still run on original clay tile that failed decades ago, often invaded by oak and pecan roots. 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 in Memphis' humid climate. |
| Basement Wall Sealing | From $1,500 | Surface preparation, efflorescence removal and penetrating or membrane sealers for damp lower 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 Mid-South thunderstorm 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 Memphis' long 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. |
| 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, for the Memphis homes that have one. |
