| Service | Price | Details |
|---|---|---|
| Basement Waterproofing | From $2,500 | Complete basement waterproofing for Raleigh homes: we trace the true water path (runoff from the rolling lot against the walls, seepage through red Piedmont clay, floor cracks, a water table that jumps after hurricane rain) 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 Raleigh basements 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 Raleigh thunderstorms, 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 Oakwood and Boylan Heights 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 red clay swells and shrinks with the 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 Raleigh's summer storms and tropical 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. Seen where saturated clay backfill presses on block basement walls on sloped Raleigh lots. |
| 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 Raleigh's rolling lots where runoff arrives from uphill. |
| Drain Tile Repair & Replacement | From $750 | Repair of collapsed, clogged or root-bound footing drains: many Raleigh homes from the 1950s-1980s still run on original clay or corrugated drain lines that failed long 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 humid North Carolina 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 hurricane remnant or summer 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 Raleigh's 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, especially on walkout and hillside lots in North Raleigh and Cary. |
| 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 Raleigh walkout and sloped-lot homes. |
What Affects the Price
- Size of the area and extent of water intrusion : Larger basements or more extensive water problems require more materials and labor, increasing the overall cost.
- Accessibility and location : Difficult-to-reach areas, such as crawl spaces or finished basements, may require additional labor and time, affecting the price.
- Type of repair or system needed : Simple crack repairs are less expensive than comprehensive drainage systems or structural repairs like bowing wall stabilization.
- Permits and local regulations : Some projects may require permits or compliance with local building codes, which can add to the total cost.
