Water in your basement?
We've seen it all — and stopped it all.
A damp basement isn't just an annoyance. Left alone, it leads to mold, ruined finishes, structural cracks, and falling home value. With decades of foundation experience across Wisconsin and Northern Illinois, All Star Pro finds the real source and engineers a fix that lasts.
The Midwest is uniquely tough on foundations.
Homes across Kenosha, Racine, Milwaukee and the North Shore sit on dense clay soils that hold water against your foundation long after a rain has passed. Add 40-degree freeze-thaw swings, a high seasonal water table, and decades of original drain tile that's now silted shut, and you have the perfect recipe for a wet basement.
The good news: every one of those problems has a permanent fix. We just have to identify which combination is happening at your house — and that starts with an honest inspection, not a templated quote.
Is your basement trying to tell you something?
If any of these sound familiar, water is already moving through your foundation. The earlier we catch it, the smaller the fix.
Musty or earthy odor
A persistent damp smell almost always means trapped moisture is feeding mildew somewhere behind walls or under flooring.
Standing water or stains
Pooling water, watermark lines on the wall, or dark patches on the slab are clear evidence water is finding its way in.
White chalky residue
Efflorescence — that powdery white deposit on block or concrete — is the salt left behind every time water dries on the surface.
Cracks that keep growing
Hairline cracks that widen, step-cracks in block walls, or horizontal cracks all signal hydrostatic pressure pushing on your foundation.
Bowing or leaning walls
Walls that are no longer plumb mean the soil outside is winning. This needs structural attention before it becomes an emergency.
Visible mold or mildew
Any fuzzy growth on walls, joists, or stored items confirms there is enough moisture down there to threaten your air quality.
Rusting metal & peeling paint
Nails weeping rust, flaking paint on basement walls, or corroded furnace bases all point to long-term humidity that needs to be controlled.
Sticking doors & uneven floors
When floors slope or interior doors stop closing properly, settlement or moisture-driven movement is happening below the slab.
Everything we do to keep basements dry.
Most leaks need more than one fix. We design layered systems — exterior, interior, structural, and drainage — that work together to protect your home from every angle.
Basement Waterproofing
Permanent solutions matched to how water is actually entering — interior drainage, exterior membranes, crack injections, or fast-track shallow systems.
Foundation Crack Injection
Poured-wall cracks sealed full-depth with structural epoxy or expansive polyurethane that bonds the concrete back together.
Interior Drain Tile Systems
A perimeter drain installed at the footing relieves hydrostatic pressure and routes seepage to a sealed sump basin — perfect for cove-joint leaks.
Exterior Waterproofing Membrane
Excavation down to the footing followed by a heavy-build elastomeric membrane and protection board so water never touches the wall.
Fast-Track Shallow Drain System
A minimally invasive interior drain installed without breaking up the entire slab — ideal for finished basements with localized water.
Foundation & Structural Repair
Cracks and bowing walls aren't cosmetic — they're how a foundation tells you it's losing the fight. We stabilize before we waterproof.
Carbon Fiber Wall Reinforcement
Aerospace-grade strips epoxied vertically across cracked or bowing walls to lock them in place — no excavation, no steel, no ongoing maintenance.
Steel Wall Bracing
Heavy-gauge I-beams anchored to floor and joists to push back severely bowed walls and prevent further movement.
Foundation Underpinning & Piers
Helical or push piers driven to load-bearing strata to lift and stabilize foundations that have settled.
Crack Stitching & Block Repair
Targeted repair on block foundations using carbon stitching, urethane fill, and rebuild where individual courses have failed.
Sump Pumps & Humidity Control
A waterproofing system is only as reliable as the pump moving the water out. We size, install, and back-up every pump to commercial standards.
Primary Sump Pumps
High-capacity cast-iron pumps installed in a sealed basin with a check valve and properly sized discharge line.
Battery Backup Systems
Maintenance-free deep-cycle backup pumps that keep working through power outages — exactly when storms hit hardest.
Twin Primary Pump Setups
Two primary pumps in one basin for full redundancy in homes with high water tables or finished basements you can't risk losing.
Whole-Basement Dehumidification
Sealed-system dehumidifiers tied into your drainage to drop humidity, kill the musty smell, and stop mold before it starts.
Crawl Space Solutions
A wet crawl space pulls moist air upward into your living space all year. Encapsulation turns that dirty void into clean, dry, conditioned square footage.
Crawl Space Encapsulation
A heavy-mil reinforced vapor barrier sealed to walls and piers cuts off ground moisture and stabilizes humidity.
Crawl Space Drainage & Sump
Interior drainage and a dedicated sump pump for crawl spaces that take on standing water during storms.
Spray Foam & Insulation Upgrades
Closed-cell foam in joist bays or rim plates eliminates cold floors and slashes winter heat loss.
Yard Drainage & Gutters
Most basement leaks start outside. Fixing how water moves around your property is often the cheapest, most effective first step.
Underground Downspout Extensions
Buried solid PVC carries roof water 10–20 feet from the foundation and discharges where it can't migrate back.
Underground Sump Discharge Lines
Frost-protected lines that carry sump water far enough from the home to prevent winter freeze-back.
Gutter Replacement & Guards
Properly sized seamless gutters with leaf guards so water actually leaves the roof instead of overflowing the foundation.
Yard Grading & French Drains
Re-grading low spots and installing surface drains where the yard sheds water toward the house instead of away.
Window Wells & Egress
Window wells fail just like foundations do — and they're often the single biggest source of basement water. We rebuild them right.
Galvanized Window Well Liners
Custom-fit corrugated metal liners that hold back soil and stop wells from collapsing or filling with mud.
Window Well Drains
A dedicated drain at the bottom of the well tied into drain tile so water can never pool against the window.
Polycarbonate Well Covers
Clear, walk-on covers that let in light while keeping out leaves, animals, and weather.
Code-Compliant Egress Windows
Full egress installs that turn a dark basement into a legal bedroom — concrete cutting, window, well, drain, and finish.
Interior vs. Exterior Waterproofing
The strongest waterproofing strategies use both. Here's how they work together.
Exterior Waterproofing
Our region's heavy clay soils hold water against your foundation long after a storm passes. Exterior waterproofing keeps that pressure from ever reaching the wall.
- Full-depth excavation to the footing
- Pressure-washed and patched foundation surface
- High-build elastomeric waterproof membrane
- Dimpled protection board that creates a drainage gap
- New exterior drain tile with washed gravel and filter fabric
- Clean backfill and graded soil to shed water away
Interior Waterproofing
Even the best exterior system benefits from a backup. Interior drainage captures any water that does enter and routes it safely out — keeping the slab dry and the air healthy.
- Sub-slab perimeter drain at the footing
- Sealed sump basin with cast-iron primary pump
- Battery backup pump for power outages
- Vapor barrier on block walls to stop seepage
- Crack sealing and pipe penetration repair
- Optional whole-basement dehumidifier integration
A clear, honest process — from inspection to dry basement.
Free On-Site Inspection
We walk every wall, check the slab, look at grading, gutters, downspouts, and window wells. You get a real diagnosis — not a sales pitch.
Source-Based Diagnosis
Surface water, hydrostatic pressure, plumbing, or condensation all look similar but need very different fixes. We name the cause before we propose a solution.
Written, Itemized Estimate
Every line is spelled out: scope, materials, depth, pump specs, warranty terms. No vague packages, no upsells later.
Clean, Respectful Install
Crews show up on time, protect your floors and finishes, and clean up at the end of every day. Most projects wrap in 1–4 days.
Final Test & Warranty
We run water, verify the system, walk you through how it works, and back the install with a transferable workmanship warranty.
Transferable Lifetime Warranty
Our workmanship warranty stays with the house — a real asset when you sell.
Local & Licensed
Fully insured, deeply familiar with WI and IL codes, soils, and permits.
Real Crews, No Subcontractors
Every project is run by our own foreman-led teams, not a rotating cast.
Diagnose Before We Sell
We won't propose a system without first identifying the actual source of water.
Straight answers about wet basements.
How do I know if my basement actually needs waterproofing?+
If you see staining, smell mustiness, notice efflorescence, or have visible cracks letting in moisture, it is time for an inspection. We provide free on-site evaluations and only recommend work that solves the underlying cause.
What's the difference between interior and exterior waterproofing?+
Exterior systems stop water before it touches your foundation. Interior systems manage water that has already pushed through and route it safely out. Most lasting solutions use both layers of defense.
Do I really need a sump pump if I have exterior waterproofing?+
Yes. Exterior membranes are your first line of defense, but a sump pump handles groundwater rise during heavy rain and gives you a critical backup if anything else ever fails.
How long does a waterproofing system last?+
A properly installed system from All Star Pro is built to last decades. We use commercial-grade membranes, schedule 40 piping, and cast-iron pumps — and we back our work with a written warranty.
Is the warranty transferable if I sell the house?+
Yes. Our workmanship warranty transfers to the next owner, which is a real selling point during inspection and appraisal.
Can I waterproof my basement myself?+
Hardware-store sealers can mask a small spot for a season, but they don't address hydrostatic pressure or failed drain tile. DIY fixes almost always come back worse, and usually more expensive.
How much does basement waterproofing cost?+
Pricing depends on linear footage, wall type, and whether interior, exterior, or structural work is needed. Every estimate is free, itemized, and pressure-free.
Will waterproofing increase my home's value?+
Absolutely. A dry, transferable-warranty basement is one of the strongest selling points an older home can have, and it's the first thing inspectors look at.
How long does the work take?+
Crack injections and small interior repairs are usually a single day. Full perimeter interior drainage runs 2–4 days. Exterior excavation projects typically take 4–7 days depending on access.
Do you offer financing?+
Yes — we offer flexible financing options on qualifying projects so you can address water issues now instead of waiting for the next storm to make it worse.
