When Water Gets In, SGP Waterproofing Gets It Out — Waterproofing in Indianapolis, IN

We built SGP Waterproofing around one idea: a homeowner or property manager in Indianapolis, IN shouldn't have to wait three days for someone to look at a wet wall.

Who We Are

A Licensed Indianapolis, IN Crew That Treats Your Foundation Like Our Own

SGP Waterproofing is a licensed and insured Waterproofing contractor serving homeowners, property managers, and commercial building owners across Indianapolis, IN. 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 Indianapolis, IN response time beats most of the national franchises operating in the same zip codes.

  • Fully licensed, bonded, and insured across Indianapolis, IN
  • On call every night of the year, not just business hours
  • Upfront, written, flat-rate pricing before we start

Soil composition changes how much hydrostatic pressure builds against a foundation wall, and Indianapolis, IN'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 Indianapolis, IN 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

Most Indianapolis, IN 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

The Waterproofing Work Indianapolis, IN Property Owners Call Us For Most

We scope every Indianapolis, IN 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

A burst window well seal or a failed check valve can put inches of water in a basement in under an hour — our emergency crews carry truck-mounted extraction pumps and moisture meters to start mitigation the same day you call.

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 Indianapolis, IN neighborhoods.

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

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

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

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

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.

FAQ

Frequently Asked Questions About Waterproofing in Indianapolis, IN

How fast can a Waterproofing technician arrive in Indianapolis, IN?

Most Indianapolis, IN 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?

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?

Cost depends on square footage, the type of system needed, and whether the fix is interior drainage, exterior membrane work, or both — we won't quote a number without an in-person inspection first.

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?

The right system depends on access, budget, and what's actually driving the water in — we'll explain the trade-offs before you decide.

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?

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?

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?

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