Who We Are

The Ontario, NY Team Homeowners Call Back a Second Time

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

  • Fully licensed, bonded, and insured across Ontario, NY
  • 24/7 emergency dispatch, 365 days a year
  • Written quotes with no hidden change orders

Soil composition changes how much hydrostatic pressure builds against a foundation wall, and Ontario, NY'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.

Because we've worked enough Ontario, NY 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

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

Most Ontario, NY 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

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 Ontario, NY 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 Ontario, NY

We scope every Ontario, NY 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

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

Commercial

Commercial & Multi-Unit Waterproofing

Commercial jobs typically pair exterior membrane work with an interior collection system, since most existing commercial structures can't be fully excavated without major disruption.

Foundation

Foundation Crack Repair & Injection

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

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 Ontario, NY crawl space stops feeding moisture into the floor joists above it.

Drainage

Exterior Grading & French Drain Systems

Extending downspouts another six to ten feet away from the foundation solves more Ontario, NY drainage problems than people expect, and we'll usually check that before recommending anything more invasive.

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

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

Frequently Asked Questions About Waterproofing in Ontario, NY

How fast can a Waterproofing technician arrive in Ontario, NY?▼

For active flooding we prioritize same-day dispatch across our Ontario, NY 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?▼

Pricing varies with scope, but every Ontario, NY 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?▼

We install both — interior drain tile and sump systems for most residential jobs, and exterior membrane or French drain systems when the source is surface water or when excavation is practical.

How long does a typical waterproofing job take?▼

A single crack injection can be done in an afternoon, while a full interior drainage system typically runs two to three days start to finish.

Do you work with insurance claims for water damage?▼

Documentation from our inspection often helps speed up the claims process, but final approval is always the insurer's call.

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?▼

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?▼

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