Middleton is a small city with a farm-town edge, where new subdivisions off Highway 44 back up to irrigation canals and older homes sit on generous lots near the Boise River. The mix of 1990s ranchers, newer two-story builds, and a handful of mid-century houses means basements here face a specific set of water problems. When the canals start running in late spring, the water table under Middleton climbs fast, and that is when we get the calls.

Homeowners in the 83644 ZIP code call Boise Waterproofing because we know how Middleton's irrigation season changes the game. From the streets near Middleton High School to the newer tracts along Duff Lane, we have seen how canal seepage and snowmelt push water against foundations. We are a local crew, fully insured, and we focus only on below-grade waterproofing, foundation crack repair, and drainage.

Waterproofing Us in Middleton (83644)

Middleton sits on alluvial sand, gravel, and silt, with some cemented caliche layers that can trap water. The irrigation canals that border many properties recharge the groundwater every summer, and when the Boise River runs high from snowmelt, the water table can rise close to basement footings. We see a lot of block and poured-concrete foundations from the 1970s through the 2000s, plus a few brick and stone basements in the older parts of town. Newer homes often have daylight basements that step down a slope, which means one wall takes more hydrostatic pressure than the others. Our team understands that a crack that looks minor in August can weep steadily by June. We use epoxy and polyurethane injection for tight cracks, and when the problem is a high water table, we recommend interior drain tile and a sump pump rather than exterior excavation. We also install French drains to redirect surface water and vapor barriers to control moisture. Serving Middleton and the surrounding Boise area, we tailor every solution to the ground conditions we find.

Our experience in Middleton includes hundreds of basement inspections and repairs. We know which neighborhoods have shallow water tables and which ones deal with runoff from the foothills. We are fully insured with general liability and workers' compensation, and we are happy to walk you through your options.

How a Job Works in Middleton

Step 1: You call us at (208) 314-5276 or request a free basement inspection online. We schedule a time to visit your Middleton property and assess the foundation, drainage, and any signs of water intrusion. We will check for efflorescence, bowing walls, and how your downspouts and grading are handling water. You get an honest opinion, including whether simple crack sealing is enough or if you need a full interior drain tile system.

Step 2: Once you approve the scope, we pull any required permits through the local building department. In Middleton, work that alters drainage or cuts an egress window often needs a permit, and we handle that step. Our crew arrives with the materials and equipment for your job, whether it is a sump pump installation, foundation crack repair, or exterior waterproofing. We work clean and respect your property, especially on tight lots where access is limited. If your home is in an HOA, we coordinate the approval process with you.

Step 3: After the work is done, we clean up the site and walk through the job with you. We explain what we did, how the system works, and what maintenance to expect. We leave your basement and yard as clean as we found them, and we are available for follow-up questions.

Pricing in Middleton depends on the size of your basement, access to the foundation, and the condition of your walls. For a typical crack repair, you can expect to start around $450. A sump pump installation or replacement starts at $1,200, and a battery backup sump pump starts at $900. If you need an interior drain tile system, it starts at $50 per linear foot, and exterior waterproofing starts at $95 per linear foot. A full basement waterproofing project often begins around $2,500, while foundation waterproofing starts at $3,500. French drains start at $25 per linear foot. We provide a free inspection and a written estimate so you know the cost before we start. Call (208) 314-5276 to schedule your free estimate in Middleton.

My house is near the canal off Highway 44 in Middleton, and my basement gets damp every summer. What is causing that?
That dampness is almost certainly from the rising water table. When the irrigation canals are running, they seep into the surrounding soil and raise the groundwater level. If your foundation walls are porous or have small cracks, that water finds its way in. We often recommend an interior drain tile system with a sump pump to relieve the hydrostatic pressure and keep the basement dry. We can inspect your property and tell you if a simpler fix like crack injection or exterior waterproofing would work better.
My sump pump failed during a storm last spring. Can you help in an emergency?
Yes, we handle emergency calls for sump pump failures and active water intrusion. If your pump is not working or your discharge line is frozen or blocked, call us at (208) 314-5276. We will prioritize your call and get a crew out as soon as possible to assess the situation and make repairs. We also install battery backup sump pumps to prevent future failures during power outages.
What does a typical foundation crack repair cost in Middleton?
Most foundation crack repairs start around $450. The final price depends on the length and width of the crack, the wall material, and whether it is actively leaking. We use epoxy or polyurethane injection to seal cracks from the inside, which is effective for most poured concrete walls. If the crack is part of a larger drainage issue, we will explain that and give you options.
Do I need a permit for basement waterproofing or egress window installation in Middleton?
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 rules vary, so we always check with the local building department before starting. We handle the permit process for you and make sure the work meets current codes.
My neighbor and I share a property line, and I want to install a French drain near it. Do I need HOA approval?
If you are in an HOA, you will likely need approval before installing a French drain or any drainage system that changes water flow. Even without an HOA, you should check property lines and local drainage rules to avoid directing water onto a neighbor's lot. We can help you understand the setback requirements and coordinate with your HOA if needed.
Are you insured for work at my Middleton home?
Yes, we are fully insured with general liability and workers' compensation coverage. Our team is trained and covered, so you can have peace of mind while we work on your property.
What should I do to prevent basement water problems before the irrigation season starts?
Before the canals start running, check your downspouts and extend them at least six feet away from the foundation. Make sure the ground slopes away from your house, and clear any debris from window wells. If you have a sump pump, test it by pouring water into the basin and confirming it kicks on. Consider a battery backup if you do not have one. If you see efflorescence or small cracks, call us for a free inspection at (208) 314-5276 so we can address them before they become bigger issues.

Included in your service

  • Water path traced: hydrostatic pressure, wall seepage, or floor cracks

  • 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
