Who We Are

A Licensed Long Lake, MN Crew That Treats Your Foundation Like Our Own

We're a licensed, insured Waterproofing outfit built around Long Lake, MN 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 Long Lake, MN response time beats most of the national franchises operating in the same zip codes.

  • Carrying full licensing and liability coverage on every job
  • 24/7 emergency dispatch, 365 days a year
  • Written quotes with no hidden change orders

Freeze-thaw cycles, seasonal rainfall patterns, and water table depth all shift how urgently a given crack or seep needs attention in Long Lake, MN specifically. We track these patterns because they change how we prioritize scheduling during storm season versus a slow drip in the middle of a dry month.

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 Long Lake, MN inspection is checking for that kind of prior patch job before we recommend anything new.

Problem Signs

Six Warning Signs Your Long Lake, MN Property Needs Waterproofing

Water damage rarely announces itself with a flooded basement on day one. It usually shows up as one of these smaller signals first, and Long Lake, MN'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

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

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 Long Lake, MN

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 Long Lake, MN clients request most often.

Emergency

Emergency Waterproofing & Flood Response

When a sump pump fails during a storm or a foundation wall gives way, we dispatch a crew with portable pumps and extraction equipment within hours, not days.

Residential

Residential Basement Waterproofing

Interior drain tile systems, sump pump installation, and vapor barrier wall systems make up the bulk of our residential basement work across Long Lake, MN neighborhoods.

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

Low-pressure epoxy injection bonds structural cracks back together, while polyurethane injection is better suited for cracks that are still actively leaking.

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

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

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

A technician maps moisture readings, checks grading, and identifies whether the source is groundwater, surface water, or condensation.

03

Written Quote

We put the scope, materials, and price in writing so you can compare it against anyone else's estimate line for line.

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

What Long Lake, MN Customers Ask Us Most Often

How fast can a Waterproofing technician arrive in Long Lake, MN?▼

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

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?▼

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?▼

We give you a realistic timeline in the written quote so you can plan around the crew being on-site.

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?▼

In most cases yes — a French drain collects water, but it still needs a sump pump to actually move that water out and away from the foundation.

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?▼

Standing water doesn't stop us from starting; we extract it as the first step, then proceed with vapor barrier and drainage installation.

Do you service commercial properties as well as homes?▼

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