Who We Are

The Cedarhurst, NY Team Homeowners Call Back a Second Time

SGP Waterproofing is a licensed and insured Waterproofing contractor serving homeowners, property managers, and commercial building owners across Cedarhurst, NY. We didn't start as a marketing company that added waterproofing to a service list — our crews came up running sump pumps, pouring interior drain tile, and injecting epoxy into foundation cracks long before the trucks had our name on the door.

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 Cedarhurst, NY response time beats most of the national franchises operating in the same zip codes.

  • Round-the-clock emergency response, including holidays
  • Upfront, written, flat-rate pricing before we start

Soil composition changes how much hydrostatic pressure builds against a foundation wall, and Cedarhurst, 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.

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 Cedarhurst, NY 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 Cedarhurst, NY'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 Cedarhurst, 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 Cedarhurst, NY

We scope every Cedarhurst, 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

Most Cedarhurst, NY 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

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

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

Extending downspouts another six to ten feet away from the foundation solves more Cedarhurst, 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

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

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 Cedarhurst, NY

How fast can a Waterproofing technician arrive in Cedarhurst, NY?

Most Cedarhurst, NY 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?

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 Cedarhurst, 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?

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?

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?

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 Cedarhurst, NY in addition to single-family homes, including parking structures and multi-unit basements.
