Who We Are

Local Waterproofing Specialists Who've Already Seen Your Problem Before

We're a licensed, insured Waterproofing outfit built around Matthews, IN properties specifically — the clay-heavy soil, the seasonal freeze-thaw cycles, the older basements with parged walls that were never meant to hold back a modern water table. Every technician on our crew has logged real hours crawling through wet crawl spaces, not just reading about them.

We keep our crews local rather than routing calls through a national call center, which means the technician who answers your questions on the phone is often the same person standing in your basement two hours later. That continuity cuts down on the miscommunication that drags out so many waterproofing jobs.

  • Licensed and fully insured for residential and commercial work
  • Round-the-clock emergency response, including holidays
  • Upfront, written, flat-rate pricing before we start

Older Matthews, 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 Matthews, 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

How to Tell a Foundation Problem Is Getting Worse, Not Better

Most Matthews, 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

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

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 Matthews, IN homes.

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 Matthews, IN

We scope every Matthews, 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

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

We install interior perimeter drain systems tied into a sump basin, then finish the walls with a dimpled vapor barrier so any residual moisture is directed down, not trapped behind drywall.

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

If a wall is bowing rather than just cracked, we'll flag that during the inspection since injection alone won't address a structural deflection issue.

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

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

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

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

Frequently Asked Questions About Waterproofing in Matthews, IN

How fast can a Waterproofing technician arrive in Matthews, IN?▼

Response time depends on call volume and severity, but emergency water intrusion always jumps the queue ahead of routine estimates.

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?▼

We handle active flooding, sump pump failures, and failed foundation walls with same-day dispatch, portable extraction pumps, and temporary water mitigation.

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?▼

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?▼

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?▼

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?▼

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?▼

Commercial scheduling is handled separately from residential dispatch so larger projects get the coordinated planning they need.
