Randleman's mill-village homes sit on red clay along the Deep River, and that clay is the reason so many basements here stay damp. The old houses near the river and the brick ranches off Main Street were built before modern drainage, and their stone or block foundations were never meant to hold back water that has nowhere to go.

When water shows up in your basement in 27317, you want someone who knows the difference between a simple crack and hydrostatic pressure. Greensboro Waterproofing is based just up the road, and we've worked on enough Randleman homes to know that sump pumps and wall sealing are often the right first answer here. Call us at (336) 203-7271 for a free basement inspection.

Waterproofing Us in Randleman (27317)

Randleman sits in the Piedmont where the ground is red clay over decomposed granite, and that clay swells when it's wet and shrinks when it's dry. The Deep River and its tributaries cut through town, and in big storms the water table rises fast. Mill-village houses near the river often have full basements dug into that clay, with old clay footing drains that are now collapsed or clogged. Brick ranches and split-levels from the 1950s and 1960s have partly finished lower levels where efflorescence on the block walls is a common sign of moisture moving through. Newer homes on the edges of town may have poured concrete walkout basements, and those walls can crack at the corners when the clay settles. We see bowing block walls in older parts of town, and we use carbon fiber straps or wall anchors when that's the right fix. We also repair foundation cracks with epoxy or polyurethane injection, install interior drain tile and sump pumps, and seal basement walls. Our team serves Randleman and the surrounding Greensboro area, and we're fully insured with general liability and workers' compensation.

How a Job Works in Randleman

Step 1: You call (336) 203-7271 or request a free basement inspection. We schedule a time to walk your basement and foundation with you, look at the walls, floor, and any existing drain tile or sump basin, and check the grading and downspouts outside. We explain what we see and give you a written estimate before any work starts.

Step 2: On the work day, our crew arrives with the materials for your job, whether that's an interior perimeter drain, a new sump pump, crack injection, or exterior waterproofing. In Randleman, tight lots near the old mill village can mean limited access for equipment, so we plan that ahead. If your project needs a permit, such as structural foundation repair or egress window cutting, we tell you and defer to the City of Randleman building department for the rules, which vary and must be verified.

Step 3: We clean up and haul away debris, then walk the job with you. We test the sump pump and check the discharge line, and we leave your basement and yard as clean as we found them. You get a transferable warranty on the work.

Pricing in Randleman depends on the job. Foundation crack repair starts at $450, and sump pump installation or replacement starts at $1,200. Interior drain tile starts at $50 per linear foot, and exterior basement waterproofing starts at $95 per linear foot. Basement waterproofing starts at $2,500, and foundation waterproofing starts at $3,500. A French drain starts at $25 per linear foot, and vapor barrier installation starts at $3 per square foot. Basement wall sealing starts at $1,500, and battery backup sump pumps start at $900. Bowing wall repair starts at $600, and basement mold remediation starts at $1,500. Window well drainage and repair starts at $650, and egress window installation starts at $4,500. The final cost depends on the size of your basement, access to the work area, the condition of your foundation, and how urgent the problem is. Call (336) 203-7271 for a free estimate.

My basement in the old mill village near the Deep River stays damp even when it hasn't rained. What's going on?
That dampness is usually the water table staying high in the clay, not a single leak. We often find that wall sealing alone won't fix it, and an interior drain tile system with a sump pump is the better answer to manage hydrostatic pressure. We'll check your walls, floor, and existing drain tile during a free inspection and tell you plainly what we think.
Water is coming into my basement right now after a storm. Can you help in Randleman?
Yes. Call us at (336) 203-7271. We handle storm and snowmelt emergencies in Randleman, including sump pump failures, frozen or blocked discharge lines, and actively weeping foundation cracks. We'll talk you through what to do while we get there, and we can often stop the water the same day.
What does a typical basement waterproofing job cost in Randleman?
Most basement waterproofing projects here start around $2,500, but the real number depends on the size of your basement, access, and whether we're installing interior drain tile, a sump pump, or doing exterior work. Foundation crack repair starts at $450, and sump pump installation starts at $1,200. We give you a written estimate after a free inspection, so you know the cost before we start.
Do I need a permit for foundation repair or an egress window in Randleman?
Permits are commonly required for structural foundation repair, egress window cutting, and work that alters drainage or the sanitary connection of a sump discharge. The City of Randleman building department sets the rules, and thresholds vary, so we always defer to them and verify before we pull a permit. We'll tell you what applies to your job.
My neighbor's downspout empties right at our property line and my basement is wet. What can I do?
Property line drainage is a common issue in Randleman's older neighborhoods. We can inspect your foundation and grading and recommend downspout extensions or a French drain on your side to move water away. If there's an HOA, we can coordinate on any exterior changes. We don't mediate neighbor disputes, but we can tell you what your own drainage needs.
Are you insured for work at my Randleman home?
Yes. Greensboro Waterproofing is fully insured with general liability and workers' compensation coverage. We're happy to provide proof of insurance before we start work at your property.
What should I do each fall to keep my Randleman basement dry?
Before winter, test your sump pump by pouring water into the basin, and check that the discharge line isn't frozen or blocked. Clean out window wells and make sure downspouts extend away from the foundation. Look for new efflorescence or widening cracks on your basement walls. If you see anything that worries you, call us at (336) 203-7271 for a free inspection.

Our services

Our Basement Waterproofing Services in Greensboro

All your work handled by qualified professionals in Greensboro

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
