Who We Are

The Addison, MI Team Homeowners Call Back a Second Time

We're a licensed, insured Waterproofing outfit built around Addison, MI properties specifically — the clay-heavy soil, the seasonal freeze-thaw cycles, the older basements with parged walls that were never meant to hold back a modern water table. Every technician on our crew has logged real hours crawling through wet crawl spaces, not just reading about them.

Our dispatchers know the difference between a slow seep that can wait until morning and an active flood that can't, and they route calls accordingly. That triage system is the reason our average Addison, MI response time beats most of the national franchises operating in the same zip codes.

  • Licensed and fully insured for residential and commercial work
  • On call every night of the year, not just business hours
  • Flat-rate written estimates you approve before work begins

Older Addison, MI 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.

Because we've worked enough Addison, MI basements to recognize patterns, we can often tell within the first ten minutes of an inspection whether a problem is isolated or connected to a larger drainage issue affecting the whole block. That context shapes whether we recommend a small crack repair or a full interior system.

Problem Signs

What a Failing Foundation Actually Looks Like Before It Floods

Most Addison, MI 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

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

Drywall that feels soft, bubbles, or shows a tide line near the floor is already absorbing groundwater — by the time you see it, the insulation behind it is usually soaked too.

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 Addison, MI 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

The Waterproofing Work Addison, MI Property Owners Call Us For Most

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 Addison, MI clients request most often.

Emergency

Emergency Waterproofing & Flood Response

A burst window well seal or a failed check valve can put inches of water in a basement in under an hour — our emergency crews carry truck-mounted extraction pumps and moisture meters to start mitigation the same day you call.

Residential

Residential Basement Waterproofing

Most Addison, MI basements need a combination of interior drainage and a properly sized sump pump — we size the system to your square footage and soil type, not a one-size-fits-all package.

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

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

Encapsulation starts with removing standing water and debris, then sealing the space with a 12-20 mil liner and a dehumidifier sized to the cubic footage.

Drainage

Exterior Grading & French Drain Systems

We trace surface water back to its source, which is often a downspout discharging too close to the foundation or a grade that slopes the wrong direction entirely.

How It Works

What Actually Happens After You Call SGP Waterproofing

01

Call & Phone Assessment

A dispatcher walks through symptoms with you on the phone so the crew that shows up already has a rough idea what they're dealing with.

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 Addison, MI

How fast can a Waterproofing technician arrive in Addison, MI?▼

Most Addison, MI 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?▼

Pricing is disclosed in full before you sign anything, and we walk through each line item so nothing is a surprise later.

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?▼

Pricing varies with scope, but every Addison, MI customer gets an itemized written estimate before any work is authorized, so there's never a guessing game.

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 can document moisture readings, photos, and scope of damage to support an insurance claim, though coverage and claim approval are ultimately determined by your carrier.

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?▼

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?▼

We work with property managers, HOAs, and commercial building owners across Addison, MI in addition to single-family homes, including parking structures and multi-unit basements.
