Davidson is a town where 1900s brick foundations near Davidson College sit a few streets away from newer homes on slopes running toward Lake Norman. That mix of old brick and modern builders means one waterproofing approach never fits all. We work with both, and we know the difference.

Homeowners in 28036 call Charlotte Waterproofing because we understand the local ground: red clay that swells after summer storms, a water table that rises fast, and hillside runoff that finds every weak point. Whether you are near the town green or off a quiet street toward the lake, we have seen the same problems you are facing.

Waterproofing Us in Davidson (28036)

Davidson sits on the Piedmont, and the soil here is mostly deep red clay with pockets of weathered granite and gneiss. That clay expands when wet and shrinks when dry, which puts constant pressure on foundation walls. Older homes near the college often have brick or stone foundations with lime mortar that needs to breathe, so breathable parging is often the right call instead of a sealed membrane. Newer homes on slopes toward Lake Norman deal with hillside runoff and hydrostatic pressure from a high water table, where interior drain tile and a properly sized sump pump make more sense than exterior excavation. We also see plenty of window well issues and foundation cracks that open up after heavy summer thunderstorms.

Our team has worked across Davidson and the surrounding Charlotte area for years, from small crack repairs to full perimeter drainage systems. We know how the grade changes block by block and how the local building department reviews structural and drainage work.

How a Job Works in Davidson

Step 1: You call us at (980) 272-4046 or request a free basement inspection online. We schedule a visit, walk the property with you, and assess the foundation, drainage, and any signs of water intrusion. You get a written scope and a clear price before any work starts.

Step 2: On the work day, our crew arrives with the materials and equipment for your specific job, whether that is epoxy injection for a crack, an interior drain tile system, or a new sump pump. Tight lots near the college can mean careful staging, and we always check whether a permit is needed for structural or egress work. If your home is in an HOA, we coordinate access and any required approvals before we dig.

Step 3: We clean up completely, haul away debris, and walk the finished work with you. You will see the drain tile, the sealed crack, or the new pump running before we leave. We do not consider a job done until you understand what was installed and how to maintain it.

Pricing in Davidson depends on the job, but here are realistic starting points from our service list. Foundation crack repair starts at $450. Sump pump installation or replacement starts at $1,200, and a battery backup adds from $900. Interior drain tile runs from $50 per linear foot, while exterior basement waterproofing starts at $95 per linear foot. French drains start at $25 per linear foot, and a full basement waterproofing project starts at $2,500. Foundation waterproofing starts at $3,500. Factors that move the price include the length of the run, access for equipment, the condition of the existing foundation, and how quickly you need us out. Call (980) 272-4046 for a free estimate and a straight answer on what your home actually needs.

My 1920s brick foundation near Davidson College has white powder on the walls. Is that a problem?
That white powder is efflorescence, a sign that moisture is moving through the brick and mortar. On older homes near the college, the mortar is often soft and needs to breathe. We usually recommend breathable parging rather than a sealed membrane, along with fixing the grading and downspouts that are sending water toward the wall. A free inspection will tell you whether it is a simple moisture fix or something more.
Water is coming into my basement during heavy storms. How fast can you respond in Davidson?
We prioritize active water intrusion, especially when a sump pump has failed or a crack is weeping. Call (980) 272-4046 and describe what you are seeing. We will schedule the soonest available visit and can often provide temporary guidance over the phone while you wait. For a pump running continuously or a discharge line that is frozen or blocked, we treat it as urgent.
What does a typical foundation crack repair cost in Davidson?
Most single crack repairs start at $450 and go up from there depending on the crack width, whether it is actively leaking, and access. If the crack is part of a larger hydrostatic pressure problem, we may recommend interior drain tile instead of repeated sealing. We give you the price before work begins and explain why one option fits better than the other.
Do I need a permit for foundation crack repair or an egress window in Davidson?
Permits are commonly required for structural foundation repair, egress window cutting, and work that alters drainage or the sanitary connection of a sump discharge. Rules vary, so we always check with the local building department before starting. You can also review the Town of Davidson's official website at https://www.townofdavidson.org for general information, and we will confirm the specific requirements for your project.
My neighbor's downspout drains onto my property line. What can I do?
Property line drainage is a common issue in Davidson's older neighborhoods where lots are close together. We can assess where the water is actually going and recommend solutions like extending downspouts, regrading, or a French drain on your side of the line. If you are in an HOA, check your covenants first. We do not mediate disputes, but we can give you a clear picture of the water path and the fixes that stay within your property.
Are you insured for work at my Davidson home?
Yes. Charlotte Waterproofing is fully insured with general liability and workers' compensation coverage. We are happy to provide proof of insurance before we start any job. You can call (980) 272-4046 with any coverage questions.
What should I do to prevent basement water problems before the next storm season in Davidson?
Check your gutters and downspouts and make sure they discharge well away from the foundation. Look for low spots near the house and fill them so water drains away. Test your sump pump by pouring a bucket of water into the basin and listening for it to kick on. If you see new cracks or efflorescence, call us for a free inspection before the next round of summer thunderstorms.

Our Basement Waterproofing Services in Charlotte

All your work handled by qualified professionals in Charlotte

Basement Waterproofing

We diagnose the actual water path first, then build the system that matches it.

Included in your service

  • Water path traced: hydrostatic pressure, wall seepage, or floor cracks
  • Interior drain tile, sump basin, wall treatment, and vapor barrier as needed
  • Honest call on what you need and what you do not
  • Transferable warranty on the system, terms set out in your written contract
Learn more→

Interior Drain Tile System

Perimeter drain tile at the footing, routed to a sump basin. Installed in any season.

Included in your service

  • Slab edge opened, perforated pipe laid in washed stone at the footing
  • Water captured before it reaches the floor, channeled to the sump basin
  • Works through winter, unlike exterior excavation
  • Concrete restored flush, basement left clean and usable
Learn more→

Exterior Basement Waterproofing

The most thorough fix there is: excavation to the footing, membrane, and new drains.

Included in your service

  • Excavation to the footing, foundation wall cleaned and repaired
  • Waterproof membrane and dimple board applied to the outside face
  • New footing drains bedded in stone and wrapped in filter fabric
  • Straight guidance on when exterior work earns its cost over an interior system
Learn more→

Foundation Waterproofing

Block, poured, and fieldstone foundations, each treated for how it actually fails.

Included in your service

  • Parging and crack repair matched to the wall construction
  • Membrane or crystalline treatment selected for the substrate
  • Drainage corrected so the treatment is not asked to hold back standing water
  • Period-appropriate approach for pre-1940 stone and block walls
Learn more→

Foundation Crack Repair

Epoxy bonds a structural crack, polyurethane seals a wet and moving one. We use the right one.

Included in your service

  • Crack graded first: cosmetic, actively weeping, or still moving
  • Injection ports set along the full depth of the crack
  • Epoxy injection where the wall needs structural bonding
  • Polyurethane injection where the crack is wet and needs to stay flexible
Learn more→

Sump Pump Installation & Replacement

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

Included in your service

  • Zoeller and Liberty pumps sized to your pit and inflow
  • Sealed basin and check valve to stop backflow between cycles
  • Discharge line routed and freeze-protected for spring snowmelt
  • Old pump and debris removed, cycle tested before we leave
Learn more→

Bowing Wall Repair

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

Included in your service

  • Bow measured and monitored to establish how far the wall has moved
  • Carbon fiber straps bonded to the wall for lighter bows
  • Steel wall anchors where the bow needs active correction
  • The clay soil pressure driving it addressed, not just the wall braced
Learn more→

French Drain Installation

Intercept surface and groundwater before it ever reaches the foundation.

Included in your service

  • Trench graded to fall, gravel bed and perforated pipe wrapped in filter fabric
  • Curtain drains placed uphill of the house where the water actually arrives
  • Outlet tied to daylight or to a pump basin, never left to pond
  • Grading and downspout extensions corrected as part of the job
Learn more→

Drain Tile Repair & Replacement

Many homes here still run on original clay tile that stopped draining decades ago.

Included in your service

  • Camera inspection to locate the collapse, blockage, or root intrusion
  • Targeted excavation rather than replacing the entire run
  • Modern PVC replacement bedded in washed stone
  • Flow tested end to end once the line is reconnected
Learn more→

Vapor Barrier Installation

Stop moisture migrating through block and concrete before you finish the space.

Included in your service

  • Heavy-duty wall and floor barrier sealed at seams and penetrations
  • Fitted around the drainage system so moisture is managed, not trapped behind it
  • The right prep step before framing a basement finish
  • Paired with drainage, because a barrier alone does not remove water
Learn more→

Basement Wall Sealing

Sealers fix minor dampness. They do not beat hydrostatic pressure, and we will tell you which you have.

Included in your service

  • Surface prepared and efflorescence removed down to sound masonry
  • Penetrating or membrane sealer chosen for the wall and the conditions
  • Plain diagnosis of whether sealing is genuinely enough for your basement
  • If the water table is the driver, we say so instead of selling you a coating
Learn more→

Battery Backup Sump Pumps

The power goes out during the storm, which is exactly when the pump matters most.

Included in your service

  • Backup pump and battery sized to your pit and expected inflow
  • Automatic changeover the moment the primary pump loses power
  • Audible alarm so a failure does not go unnoticed
  • Runtime explained honestly, and maintenance checks available
Learn more→

Free Basement Inspection

A written assessment with photos, and a straight answer if nothing is actually wrong.

Included in your service

  • Walls, floor, cracks, and sump system checked point by point
  • Exterior grading, downspouts, and window wells reviewed as water sources
  • Photos and a written explanation of what needs fixing now and what can wait
  • Free and no obligation, including when our answer is that you need nothing
Learn more→

Basement Mold Remediation

Removal paired with the moisture fix, because mold returns wherever the water does.

Included in your service

  • Containment set up before any affected material is disturbed
  • Affected surfaces treated and remediated, damaged materials removed
  • Musty smell traced back to the moisture source rather than masked
  • Drainage or dehumidification added so growth does not restart
Learn more→

Window Well Drainage & Repair

A well that fills becomes a bucket of water held against your foundation.

Included in your service

  • Well excavated and a drain tied into the footing drain or a stone bed
  • Liner set true and backfilled with free-draining stone
  • Clear cover fitted to keep out rain, leaves, and snow
  • A leak source homeowners rarely suspect and inspections often miss
Learn more→

Egress Window Installation

Code-compliant egress, cut and flashed so the new space stays dry.

Included in your service

  • Opening cut and framed to the required egress dimensions
  • Window flashed and sealed against the foundation wall
  • Well drained properly so the new opening is not a water entry point
  • Permit requirements confirmed with the local building department first
