Who We Are

A Licensed Decatur, 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 Decatur, 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 Decatur, IN response time beats most of the national franchises operating in the same zip codes.

  • Carrying full licensing and liability coverage on every job
  • 24/7 emergency dispatch, 365 days a year
  • Flat-rate written estimates you approve before work begins

Older Decatur, IN 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 Decatur, IN 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

What a Failing Foundation Actually Looks Like Before It Floods

Most Decatur, 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

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 Decatur, IN 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 Decatur, IN

We scope every Decatur, 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

Once the water is out, we run air movers and dehumidifiers to bring humidity down before mold has a chance to establish itself in drywall or subfloor.

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 Decatur, IN neighborhoods.

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

A properly encapsulated crawl space with its own sump discharge line keeps humidity below the threshold where wood rot and mold can take hold.

Drainage

Exterior Grading & French Drain Systems

We trace surface water back to its source, which is often a downspout discharging too close to the foundation or a grade that slopes the wrong direction entirely.

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

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

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

What Decatur, IN Customers Ask Us Most Often

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

Most Decatur, 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?

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?

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?

We give you a realistic timeline in the written quote so you can plan around the crew being on-site.

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?

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?

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