Our services

Our Basement Waterproofing Services in Boise

All your work handled by qualified professionals in Boise

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

“We had water seeping into our finished basement every spring, and Boise Waterproofing sealed the whole thing up in about two days. The crew of three was super clean and hauled away all the old caulk and debris. Bone dry down there now, even after that big rain last month.”

“Our old sump pump died and the pit was filling up fast. They got out to our place in Eagle within a couple days and swapped in a new pump plus a battery backup. Only gripe is they were a little late on the first appointment, but the install itself was solid and quiet.”

“Had them cut in an egress window with a proper window well in our basement bedroom. I was nervous about the digging, but the crew kept everything tidy and the drainage in the well works great. Feels like a real room now instead of a cave.”

“Foundation waterproofing on our 1970s ranch house. They dug down along the north wall, sealed it, and put in proper drainage. Two weeks of work and they cleaned up so well you couldn't even tell they'd been digging. No more damp smell in the crawlspace.”

“They installed an interior drain tile system along two walls of our basement and tied it into a new sump pit. I was amazed at how little dust there was for that much concrete cutting. Water hasn't come near the floor since.”

“Had a couple of hairline cracks weeping in the concrete basement walls, and they sealed them and did a full wall sealing job. Fast, fair price, and they explained everything before starting. Small thing, but I wish they'd given a bit more notice before showing up.”

“Our backyard kept flooding toward the house, so they put in a French drain along the foundation. Crew of four knocked it out in a day and a half and re-graded everything nicely. First big storm after, the water went exactly where it was supposed to.”

“They waterproofed our basement walls and sealed the floor slab after we kept getting moisture creeping up through the concrete. The vapor barrier and sealing made a huge difference, and the musty smell is finally gone. Genuinely relieved we called them.”
