We diagnose the actual water path first, then build the system that matches it.
Included in your service
Perimeter drain tile at the footing, routed to a sump basin. Installed in any season.
Included in your service
The most thorough fix there is: excavation to the footing, membrane, and new drains.
Included in your service
Block, poured, and fieldstone foundations, each treated for how it actually fails.
Included in your service
Epoxy bonds a structural crack, polyurethane seals a wet and moving one. We use the right one.

A pump is only as good as the basin, the check valve, and where the water actually goes.

Stop the movement without rebuilding the wall, in most cases.

“We had water seeping through the block walls in our finished basement every time it rained hard. Durham Waterproofing sealed the entire 40-foot wall and now it stays bone dry. The crew even swept up the dust before they left.”
Basement Wall Sealing
“Our old sump pump died during a storm and the basement started filling up. They got a new pump installed with a battery backup in one afternoon. Total lifesavers, honestly.”
Sump Pump Installation
“Got an egress window put in so our basement bedroom would actually be legal and safe. The team cut through the brick foundation, installed the window well and tied the drainage in properly. Took about two days and they hauled away every bit of debris.”
Egress Window Installation
“They dug down along the whole back of our brick house and waterproofed the foundation properly, then backfilled and graded it. It was a big job but the crew of five knocked it out in under a week. Wish I'd done this years ago.”
Exterior Basement Waterproofing
“Had a long diagonal crack in the brick foundation wall that was letting water in. They injected it and sealed it up, and it's been dry through two big storms since. Fair price and they explained everything before starting.”
Foundation Crack Repair
“They installed drain tile along two basement walls and tied it into a new sump pit. The difference is night and day, no more standing water or musty smell. Cleaned up so well you couldn't tell they'd been there except for the dry floor.”
Interior Drain Tile System
“Our yard was channeling water straight into the foundation. Durham Waterproofing put in a gravel and French drain system along the side of the house and it solved the problem completely. Crew was friendly and finished in two days.”
French Drain Installation
“Full foundation waterproofing with drainage on our house, they did the exterior membrane, drainage board, and tied it all into the footer drain. Not cheap, but it came with a transferable warranty and the basement has stayed dry through a very wet spring.”

| Service | Starting from | Description |
|---|---|---|
| Basement Waterproofing | From $2,500 | Complete basement waterproofing for Durham homes: we trace the true water path (runoff down wooded slopes against the walls, seepage through heavy Triassic clay, floor cracks, a creek-fed water table 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 Durham basements where clay-held 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 Durham storms, 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 Trinity Park and Old North Durham 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 heavy gray clay swells and shrinks with the weather. 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 Durham'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 Triassic clay backfill presses on 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 Durham's wooded sloped lots where runoff arrives from uphill. |
| Drain Tile Repair & Replacement | From $750 | Repair of collapsed, clogged or root-bound footing drains: many Durham 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 Durham'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 wooded hillside lots in Chapel Hill and Hillsborough. |
| 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 Durham walkout and sloped-lot homes. |
