Who We Are

The Unionville, NC Team Homeowners Call Back a Second Time

We're a licensed, insured Waterproofing outfit built around Unionville, NC 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.

Because we staff locally instead of subcontracting out to whoever's available, the estimate you get over the phone tends to match the invoice you get at the end of the job — no surprise line items, no upsell script.

  • Licensed and fully insured for residential and commercial work
  • 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 Unionville, NC'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.

Because we've worked enough Unionville, NC 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

Water damage rarely announces itself with a flooded basement on day one. It usually shows up as one of these smaller signals first, and Unionville, NC'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

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 Unionville, NC 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 Unionville, NC

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 Unionville, NC clients request most often.

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

Most Unionville, NC 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

Commercial jobs typically pair exterior membrane work with an interior collection system, since most existing commercial structures can't be fully excavated without major disruption.

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

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

Extending downspouts another six to ten feet away from the foundation solves more Unionville, NC drainage problems than people expect, and we'll usually check that before recommending anything more invasive.

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

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

Waterproofing Questions We Hear Every Week in Unionville, NC

How fast can a Waterproofing technician arrive in Unionville, NC?▼

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?▼

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?▼

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 Unionville, NC 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?▼

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?▼

A single crack injection can be done in an afternoon, while a full interior drainage system typically runs two to three days start to finish.

Do you work with insurance claims for water damage?▼

Documentation from our inspection often helps speed up the claims process, but final approval is always the insurer's call.

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?▼

We assess the water depth and source first, since active groundwater intrusion changes how we sequence the encapsulation work.

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.
