Who We Are

A Licensed Cedarburg, WI Crew That Treats Your Foundation Like Our Own

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
  • 24/7 emergency dispatch, 365 days a year
  • Upfront, written, flat-rate pricing before we start

Soil composition changes how much hydrostatic pressure builds against a foundation wall, and Cedarburg, WI's mix of clay-heavy and sandy soils behaves differently depending on the neighborhood, sometimes block to block. A crew that hasn't worked the area tends to size drainage systems using generic assumptions instead of what's actually under the yard.

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

How to Tell a Foundation Problem Is Getting Worse, Not Better

Water damage rarely announces itself with a flooded basement on day one. It usually shows up as one of these smaller signals first, and Cedarburg, WI's seasonal moisture swings tend to speed the timeline up.

Sign 01

Musty Basement Odor

That damp, earthy smell in a finished or unfinished basement is usually mold or mildew feeding on moisture that's already gotten past your walls.

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

Small stair-step cracks in block walls or vertical hairline cracks in poured walls tend to widen over a season or two as hydrostatic pressure keeps pushing.

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

A window well that fills with water during heavy rain is putting direct pressure on the glass and frame, and it's one of the most common entry points we find in older Cedarburg, WI homes.

Sign 06

Standing Water After Storms

Water that pools against your foundation after every rain is telling you the drainage system, whatever's left of it, has stopped doing its job.

What We Do

Our Core Waterproofing Services in Cedarburg, WI

Every job starts with the same on-site inspection, whether it's a single crack or a full interior drainage retrofit. Below are the services Cedarburg, WI clients request most often.

Emergency

Emergency Waterproofing & Flood Response

Once the water is out, we run air movers and dehumidifiers to bring humidity down before mold has a chance to establish itself in drywall or subfloor.

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

We work with property managers on phased scheduling so a commercial waterproofing retrofit doesn't shut down an entire building at once.

Foundation

Foundation Crack Repair & Injection

If a wall is bowing rather than just cracked, we'll flag that during the inspection since injection alone won't address a structural deflection issue.

Crawl Space

Crawl Space Encapsulation & Sump Systems

We install heavy-gauge vapor barriers, seal foundation vents, and add a dedicated sump basin so a damp Cedarburg, WI crawl space stops feeding moisture into the floor joists above it.

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

Once installation wraps, we test the sump pump under load and walk you through the warranty paperwork before we leave the site.

FAQ

Frequently Asked Questions About Waterproofing in Cedarburg, WI

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

Most Cedarburg, WI emergency calls get a technician on-site within a few hours; non-urgent inspections are typically scheduled within one to two business days.

Do you provide upfront pricing?▼

We quote the full scope in writing after the inspection, so there's no hourly billing or surprise change orders once installation starts.

What emergency services are available?▼

Emergency crews are equipped to stabilize the situation immediately, then schedule the permanent fix once the immediate flooding risk is under control.

How much does basement waterproofing typically cost?▼

Cost depends on square footage, the type of system needed, and whether the fix is interior drainage, exterior membrane work, or both — we won't quote a number without an in-person inspection first.

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

Hairline cracks are actually the ideal time to call, since injection repair is faster and cheaper before hydrostatic pressure has a chance to widen the gap.

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?▼

A French drain without a sump pump just relocates water to one spot; the pump is what actually discharges it away from the home.

Do you offer a warranty on your waterproofing work?▼

Warranty length and coverage vary by service type, and we'll spell out the specifics in writing before the job starts.

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

Yes — we pump out existing standing water first, then move into encapsulation and sump installation once the space is dry enough to work in safely.

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.
