Who We Are

Local Waterproofing Specialists Who've Already Seen Your Problem Before

Every SGP Waterproofing technician working in Cedarburg, WI carries the same licensing, the same insurance coverage, and the same set of tools whether the job is a single cracked footing or a full interior drainage system. We built the company on the idea that a homeowner shouldn't need three quotes and two weeks of waiting to get an honest answer.

Because we staff locally instead of subcontracting out to whoever's available, the estimate you get over the phone tends to match the invoice you get at the end of the job — no surprise line items, no upsell script.

  • Fully licensed, bonded, and insured across Cedarburg, WI
  • Round-the-clock emergency response, including holidays
  • Written quotes with no hidden change orders

Older Cedarburg, WI neighborhoods often have block foundations poured decades before modern drainage codes existed, while newer subdivisions tend to run poured concrete with a perimeter drain that was installed correctly but has since clogged with silt. Knowing which era of construction you're dealing with changes the repair plan before a single tool comes out of the truck.

We also see a lot of properties where a previous waterproofing attempt only addressed the symptom — a topical sealant painted over a cracked wall, for example — without solving the pressure or grading issue causing the crack in the first place. Part of every Cedarburg, WI inspection is checking for that kind of prior patch job before we recommend anything new.

Problem Signs

Six Warning Signs Your Cedarburg, WI Property Needs Waterproofing

Most Cedarburg, WI water intrusion problems don't start as a flood — they start small, and they get worse on a schedule. Here's what our technicians look for on a first inspection.

Sign 01

Musty Basement Odor

A persistent musty smell almost always means moisture is present somewhere in the wall assembly, even if you can't see a wet spot yet.

Sign 02

White Powdery Efflorescence

Efflorescence forms when water carries dissolved minerals through porous concrete and leaves them on the surface as it dries — a clear sign moisture is actively passing through.

Sign 03

Hairline Wall Cracks

A crack that's a sixteenth of an inch wide today can become a sixteenth of an inch wider by next spring if the pressure behind the wall isn't relieved.

Sign 04

Damp or Bubbling Drywall

Bubbling paint or soft drywall near the baseboards is one of the last signs to show up, which means moisture has typically been present for weeks already.

Sign 05

Window Well Flooding

If your window wells hold water for more than an hour after a storm, that water has nowhere to go but toward the seal around your basement window.

Sign 06

Standing Water After Storms

Puddling near the foundation that doesn't drain within a few hours usually means grading, gutters, or a failing perimeter drain — and it's the fastest path to a flooded basement.

What We Do

Our Core Waterproofing Services in Cedarburg, WI

We scope every Cedarburg, WI job in person before quoting it, because two houses with the same symptom rarely need the same fix. These are the five services that make up most of our workload.

Emergency

Emergency Waterproofing & Flood Response

Active flooding gets priority dispatch. We arrive with submersible pumps, air movers, and moisture-mapping tools to stop the water first and diagnose the long-term fix second.

Residential

Residential Basement Waterproofing

We install interior perimeter drain systems tied into a sump basin, then finish the walls with a dimpled vapor barrier so any residual moisture is directed down, not trapped behind drywall.

Commercial

Commercial & Multi-Unit Waterproofing

Parking garages, below-grade retail space, and multi-family basements need waterproofing membranes and drainage systems rated for continuous traffic and higher hydrostatic load.

Foundation

Foundation Crack Repair & Injection

Crack injection is often the most cost-effective Cedarburg, WI repair when the crack is isolated and the wall itself hasn't bowed or shifted.

Crawl Space

Crawl Space Encapsulation & Sump Systems

We also insulate exposed ductwork inside the crawl space while we're in there, since condensation on cold ducts is a second moisture source people rarely think about.

Drainage

Exterior Grading & French Drain Systems

Exterior French drains paired with corrected grading are usually the first thing we recommend for a property that's flooding from the outside in, not the inside out.

How It Works

What Actually Happens After You Call SGP Waterproofing

01

Call & Phone Assessment

You describe what you're seeing and we ask a few questions to gauge urgency before anyone gets in a truck.

02

On-Site Inspection

We walk the interior and exterior with a moisture meter and flashlight, tracing water back to its actual entry point instead of guessing.

03

Written Quote

You get a flat-rate, itemized quote before any work starts — no verbal estimate that changes once the crew shows up.

04

Installation & Walkthrough

Most residential jobs finish in one to three days, and we walk the property with you afterward to confirm every drain, pump, and seal is working.

FAQ

Frequently Asked Questions About Waterproofing in Cedarburg, WI

How fast can a Waterproofing technician arrive in Cedarburg, WI?▼

For active flooding we prioritize same-day dispatch across our Cedarburg, WI coverage area; routine inspections usually book within 48 hours.

Do you provide upfront pricing?▼

Yes — every job gets a flat-rate, written quote before work begins, and that number doesn't change once the crew is on-site.

What emergency services are available?▼

Our emergency response covers water extraction, temporary pump-outs, and emergency crack sealing to stop active intrusion until permanent repairs are scheduled.

How much does basement waterproofing typically cost?▼

We avoid quoting ballpark numbers over the phone because two basements with the same symptom can need very different fixes.

Will you repair hairline foundation cracks or only large cracks?▼

We repair cracks of nearly any size — hairline cracks are often the easiest and least expensive to seal with polyurethane or epoxy injection before they widen.

Do you offer interior or exterior waterproofing systems?▼

Depending on what the inspection finds, we'll recommend interior drainage, exterior grading and membrane work, or a combination of both.

How long does a typical waterproofing job take?▼

Most residential interior drain tile or sump installations finish in one to three days; larger commercial membrane projects can take longer depending on square footage.

Do you work with insurance claims for water damage?▼

We're happy to provide the documentation adjusters typically request, though we recommend confirming your specific coverage details directly with your insurance provider.

Is a sump pump necessary if I already have a French drain?▼

We can walk your specific setup during an inspection and tell you honestly whether your existing drain needs a pump added.

Do you offer a warranty on your waterproofing work?▼

Yes, every interior drainage, sump, and crack repair job comes with a written warranty, and terms are explained in full before you approve the quote.

Can you waterproof a crawl space with standing water already present?▼

We assess the water depth and source first, since active groundwater intrusion changes how we sequence the encapsulation work.

Do you service commercial properties as well as homes?▼

Yes — our commercial work covers parking garages, retail basements, and multi-family buildings, usually scheduled in phases to minimize tenant disruption.
