Garden City's riverside blocks along the Boise River sit low and tight, with a mix of small older homes and newer infill builds packed onto narrow lots. The water table here climbs every irrigation season, and that is what pushes water into basements and against foundation walls.
Homeowners in the 83703 ZIP call Boise Waterproofing because we know how water moves through these lots near the Greenbelt and the river. We handle basement waterproofing, foundation crack repair, and below-grade drainage, and we start with a free inspection so you know what you are actually dealing with.
Waterproofing Us in Garden City (83703)
Garden City is not like the foothills or the Bench. The lots along the Boise River are low, the water table is high, and many properties have small footprints with narrow side yards. That means exterior excavation is often tight or impractical, and an interior drain tile system tied to a sump basin is frequently the smarter answer. We see a lot of older homes with brick or stone foundations and partial basements, plus newer builds on the same blocks with poured walls. The soil is alluvial sand, gravel, and silt, and it stays wet longer here because the river and the canal system recharge it all season. Hydrostatic pressure shows up as efflorescence on the wall, water at the cove joint, or a crack that weeps every spring. We read those signs and tell you plainly when simple crack sealing is enough and when the real fix is drainage and pressure relief.
Our team has worked these riverside streets and the surrounding Boise area for years. We know how a discharge line needs to run here so it does not freeze or back up, and we know why a battery backup sump pump is a sensible baseline for a Garden City basement, not an upsell.

How a Job Works in Garden City
Step 1: You call (208) 314-5276 and we set up a free on-site assessment. We walk the basement and the exterior grade, check the foundation walls, look at the sump basin and discharge line, and talk through what you are seeing. You get a clear scope and a written estimate before anything starts.
Step 2: We schedule the work and pull any permit the local building department requires, which commonly covers structural foundation repair, egress window cutting, and changes to drainage or the sanitary connection of a sump discharge. On Garden City's tight lots we plan access carefully, protect the landscaping, and keep the work area contained. If an HOA is involved, we coordinate timing with you.
Step 3: We clean up, haul out debris, and do a final walkthrough with you. We test the sump pump and check valve, confirm the discharge line runs to a safe point, and leave the site clean. You see exactly what was done and how to maintain it.
Pricing in Garden City depends on the job. A foundation crack repair with epoxy or polyurethane injection typically starts around $450. A 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, exterior basement waterproofing from $95 per linear foot, and a full basement waterproofing project from $2,500. Foundation waterproofing starts at $3,500, basement wall sealing at $1,500, and vapor barrier installation at $3 per square foot. French drains start at $25 per linear foot, drain tile repair at $750, window well drainage and repair at $650, bowing wall repair at $600, and egress window installation at $4,500. The main cost factors are the size of the area, access on a tight lot, the condition of the walls and footing drain, and how urgent the water problem is. Call (208) 314-5276 for a free estimate.
