Avimor sits in the foothills above the Boise River Valley, a planned community of newer stucco and stone homes stepping down the grade on granite-heavy soil. Walkout basements are common here, and when spring snowmelt or a summer cloudburst hits those hillsides, water moves fast and finds the path of least resistance. That is usually the joint where your foundation meets the footing, or the first crack in a poured wall.

Homeowners in Avimor (83714) call Boise Waterproofing because we know this ground. We have worked the streets off Avimor Drive and around the Foothills Heritage Park area, and we understand how runoff from the Boise foothills behaves when it hits a graded lot. If your basement is damp, your sump pump is cycling nonstop, or a crack is weeping after a storm, we can take a look and tell you straight what is happening.

Waterproofing Us in Avimor (83714)

Avimor is not like the flat subdivisions in Meridian or Nampa. The lots here are graded into the hillside, which means most homes have a daylight or walkout basement on at least one side. The soil is decomposed granite mixed with clay and silt, and it does not absorb water quickly. During snowmelt or a heavy rain, water sheets down the slope and pools against foundation walls. That is hydrostatic pressure, and it is the reason we see more wet basements and bowing walls in foothill neighborhoods than on the valley floor. We also see window wells that fill up fast and discharge lines that freeze or get blocked by debris. Our team focuses on below-grade solutions: exterior waterproofing with dimple board and a proper footing drain, interior drain tile systems with a sump basin and check valve, epoxy or polyurethane injection for foundation cracks, and carbon fiber straps or wall anchors when a block wall starts to bow.

We have been serving Boise and the surrounding areas for years, and Avimor is one of our regular service zones. We know which streets have tighter access for equipment, how the HOA likes to be kept in the loop, and what the local building department expects for permits on structural or drainage work. When we inspect your basement, we will tell you if simple crack sealing is enough or if the real problem is water pressure that needs an interior perimeter drain. We are a dedicated basement waterproofing specialist, not a general foundation-repair firm or a plumber, and we stick to what we do best.

How a Job Works in Avimor

Step 1: You call us at (208) 314-5276 or request a free basement inspection online. We schedule a time to walk your property, check the foundation walls, the floor, the sump pit, the window wells, and the grading around the house. We ask about when you see water and what the weather was doing. Then we give you a written scope and a clear price before any work starts.

Step 2: On work day, our crew arrives with the materials and equipment for your specific job. In Avimor, that might mean coordinating with your HOA for parking or staging, or working around a tight side yard where the grade drops off. If your project needs a permit, such as structural foundation repair or an egress window cut, we pull it through the local building department and schedule inspections. For exterior work, we excavate down to the footing, clean and repair the wall, apply the waterproof membrane and dimple board, and install or repair the drain tile before backfilling with proper grading. For interior drain tile, we cut a perimeter channel in the slab, lay the pipe, set the sump basin, and connect the discharge line so it drains away from the house.

Step 3: When the work is done, we clean up. We haul away debris, wash down the area, and walk the job with you. We test the sump pump, show you how the system works, and leave you with a transferable warranty on our work. We do not leave a mess behind.

Pricing in Avimor depends on the size of your basement, how easy it is to access the work area, the condition of your walls and drainage, and how urgent the problem is. For a typical home here, foundation crack repair starts at $450, sump pump installation or replacement starts at $1,200, and a battery backup sump pump starts at $900. Interior drain tile runs from $50 per linear foot, while exterior basement waterproofing starts at $95 per linear foot. A full basement waterproofing project starts at $2,500, and foundation waterproofing starts at $3,500. French drains start at $25 per linear foot, and window well drainage and repair starts at $650. We always provide a free inspection and a written estimate before any work begins, so you know exactly what to expect. Call (208) 314-5276 to schedule yours.

My walkout basement in Avimor gets wet every spring when the snow melts. Is that normal for this area?
It is common, but it is not something you have to live with. Avimor's hillside lots and granite-based soil shed snowmelt quickly, and that water often collects against the foundation. If you are seeing dampness or water on the floor, the likely cause is hydrostatic pressure or a failed footing drain. We can inspect your basement and tell you whether a simple crack repair or a full interior drain tile system is the right fix.
What should I do if water is actively coming into my basement during a storm in Avimor?
First, stay safe and avoid electrical panels if the floor is wet. If you have a sump pump, make sure it is running and the discharge line is clear. Then call us at (208) 314-5276. We prioritize emergency calls in Avimor and the surrounding Boise area, and we can help you stop the water and plan the permanent repair.
How much does a typical basement waterproofing job cost in Avimor?
Most Avimor homeowners spend between $2,500 and $8,000 depending on the scope. A basic interior drain tile system with a sump pump often lands in that range, while exterior excavation on a walkout lot can run higher because of access and soil conditions. Crack repair alone can be as low as $450. We give you a firm written price after a free inspection, so there are no surprises.
Do I need a permit for foundation crack repair or an egress window in Avimor?
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 by jurisdiction, 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 code.
My HOA wants to approve any exterior work. Can you help with that?
Yes. We work in Avimor regularly and understand that the HOA has design and staging requirements. We can provide the documentation your HOA needs, such as scope of work and contractor insurance, and we coordinate scheduling so equipment and materials do not block neighbors. If there is a property-line question about drainage discharge, we follow local setback rules and talk with you about the best placement.
Are you insured for work at my Avimor home?
Yes. Boise Waterproofing is fully insured with general liability and workers' compensation coverage.
What maintenance should I do each fall to prevent basement water problems in Avimor?
Before the freeze, test your sump pump by pouring water into the basin and making sure it kicks on and shuts off. Check that the discharge line is not frozen or clogged and that it drains well away from the foundation. Clean window wells of leaves and debris. Look for new cracks or efflorescence on the basement walls. If you see anything that concerns you, call us for a free inspection before the spring melt.

Learn more→

  • 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→

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

Included in your service

  • 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

  • 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

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
