Who We Are

The Kensington, NY Team Homeowners Call Back a Second Time

Every SGP Waterproofing technician working in Kensington, NY 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.

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

  • Carrying full licensing and liability coverage on every job
  • On call every night of the year, not just business hours
  • 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 Kensington, NY 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 Kensington, 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 Kensington, 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

Those white, chalky mineral deposits on block or poured concrete walls are salt left behind after water has migrated through the concrete and evaporated.

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

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

Puddling near the foundation that doesn't drain within a few hours usually means grading, gutters, or a failing perimeter drain — and it's the fastest path to a flooded basement.

What We Do

Five Ways We Keep Kensington, NY Basements, Crawl Spaces, and Foundations Dry

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 Kensington, NY 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

For finished basements we route the drain tile beneath the existing slab edge, which limits how much flooring has to come up during installation.

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

We classify every crack before injecting it — structural cracks get epoxy, active leaks get flexible polyurethane that expands to fill voids behind the wall.

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 Kensington, NY 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

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

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 Kensington, NY

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

Most Kensington, 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?

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 Kensington, 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?

No crack is too small to inspect; catching it early usually means a smaller repair bill down the road.

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?

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?

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.
