Who We Are

A Licensed New London, OH Crew That Treats Your Foundation Like Our Own

Every SGP Waterproofing technician working in New London, OH 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 New London, OH 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
  • Upfront, written, flat-rate pricing before we start

Older New London, OH 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 New London, OH 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 New London, OH 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

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

Our Core Waterproofing Services in New London, OH

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 New London, OH 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

Most New London, OH 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

We coordinate directly with building engineers and HOA boards so the scope, timeline, and access requirements are agreed on before a crew ever shows up on-site.

Foundation

Foundation Crack Repair & Injection

Crack injection is often the most cost-effective New London, OH 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 New London, OH 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 New London, OH drainage problems than people expect, and we'll usually check that before recommending anything more invasive.

How It Works

Our Four-Step Waterproofing Process in New London, OH

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.

3

Specialized Equipment & Training

Our crews run truck-mounted extraction units, moisture meters, and thermal imaging cameras — not a shop-vac and a guess.

4

Satisfaction Guarantee

We stand behind the installation with a written warranty, and we'd rather send a crew back for a free fix than lose a customer over it.

FAQ

What New London, OH Customers Ask Us Most Often

How fast can a Waterproofing technician arrive in New London, OH?▼

For active flooding we prioritize same-day dispatch across our New London, OH 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?▼

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 New London, OH 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?▼

Hairline cracks are actually the ideal time to call, since injection repair is faster and cheaper before hydrostatic pressure has a chance to widen the gap.

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?▼

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?▼

We back our work with a written, often transferable warranty — useful if you sell the property before the coverage period runs out.

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.
