Who We Are

We built Arrow Tight Waterproofing on a simple premise: waterproofing work across South Carolina, SC should be diagnosed correctly the first time, not sold as a guess and revisited three times.

Licensing here isn't a formality — every crew member is licensed in SC and specifically trained in the below-grade water intrusion work that Foundation Crack Repair actually requires.

We run a dispatch-first model: local crews stocked with diagnostic gear and repair materials, ready to move on active water intrusion the same day it's reported.

Transparency doesn't end once the quote is signed — we walk you through what was actually done once the crew finishes, not just what was proposed at the start.

Warning Signs You Shouldn't Wait On

Catching these signs early usually means a smaller repair bill and a lot less disruption to your home.

That persistent musty odor downstairs almost always traces back to trapped moisture somewhere in the wall or floor assembly.

Efflorescence, that white crusty residue on foundation walls, is water evaporating and leaving mineral salts behind.

Doors and windows that stick or won't latch properly, especially on the lowest level.

Even a crack thinner than a coin can be an active entry point once hydrostatic pressure builds behind the wall.

If a heavy storm reliably means a wet spot on the basement floor, that's a pattern, not bad luck.

An overworked sump pump is a warning sign in itself — it's compensating for something upstream.

Hold a level against your foundation wall — even a small deviation from plumb is worth having evaluated.

Rising humidity readings in the basement that a dehumidifier can't keep up with.

If metal items in your basement are corroding faster than they should, ambient moisture is almost certainly the cause.

Every service below starts from the same diagnostic-first approach, whether the job is a small crack injection or a full exterior excavation.

Emergency Water Extraction & Stabilization

Active flooding gets priority dispatch, with crews arriving equipped to extract water immediately and begin drying before secondary damage sets in. We follow extraction with a full moisture survey so the permanent fix addresses the actual source, not just the visible symptom.

Interior Drain Tile & Sump Systems

A perimeter drain tile channel installed below the slab intercepts groundwater before it can reach your floor, routing it to a properly sized sump basin and pump. Every basin includes a check valve, sealed lid, and battery backup so a power outage doesn't undo the fix.

Foundation Crack Injection

Non-structural cracks respond well to polyurethane or epoxy injection depending on whether water is actively present and whether the crack is still moving. Injection resin fills the full depth of the crack, not just the visible surface.

Exterior Excavation & Membrane Application

Where the source is grading, a failed footing drain, or membrane failure visible from outside, exterior excavation and a rubberized membrane address the problem at its origin.

Crawl Space Encapsulation & Vapor Control

A sealed, encapsulated crawl space with a reinforced vapor barrier cuts off the ground moisture that feeds humidity, mold, and wood rot before it ever reaches your living space.

Sump Pump Installation & Battery Backup

A properly sized primary pump paired with a battery backup is the last line of defense against basement flooding when the power goes out during a storm. Cellular notification add-ons alert your phone directly if the system is ever triggered.

Wall Vapor Barrier & Structural Reinforcement

For walls showing early bowing alongside seepage, carbon fiber straps or steel wall anchors can arrest further movement before it becomes a bigger structural concern. We explain the engineering rationale before recommending any wall reinforcement work.

Why South Carolina, SC Homeowners Choose Arrow Tight Waterproofing

Five things that actually separate a specialized Foundation Crack Repair crew from a general contractor with a truck and a sump pump on hand.

A lot of companies claim to offer Foundation Crack Repair, but the difference shows up in how the job is actually diagnosed and executed — not in the advertising.

Same-Day Response for Active Intrusion

Regional crews are staged specifically to keep response windows tight across our South Carolina, SC coverage area, day or night.

2

Written, Itemized Pricing — No Surprises

You'll know the exact cost before work starts — no hourly guessing games, no mid-job upcharges for what a proper inspection should have caught.

3

Diagnosis Before Recommendation, Always

We run a full moisture survey — wall cameras, hydrostatic pressure readings, crack classification — before recommending any specific system.

Every crew member holds waterproofing-specific licensure and completes ongoing training in drain tile, injection, and structural crack evaluation.

5

Written Warranty on Every Installed System

Drain tile, sump installations, and crack injections all carry a written warranty against failure at the treated location.

How a Foundation Crack Repair Project Actually Works

Four clear steps, no shortcuts skipped along the way — here's what actually happens between your first call and a finished, tested repair.

1

Call & Triage

One call connects you to local dispatch, not a national call center — they'll ask a few questions to understand what you're seeing and prioritize accordingly.

2

On-Site Diagnostic Visit

The diagnostic visit maps your full basement or crawl space perimeter before any repair is recommended.

3

Written Quote & Scheduling

You'll receive an itemized, written quote broken down by system component before agreeing to anything.

4

Installation & Verification

We test drain tile flow, pump activation, and injection fill before the crew leaves the property.

Frequently Asked Questions

High-intent questions we hear most from Foundation Crack Repair customers across South Carolina, SC.

How fast can a Foundation Crack Repair technician arrive in South Carolina, SC?+
Active water intrusion moves to priority scheduling, and most South Carolina, SC service areas see a technician within hours of the call.
Do you provide upfront, flat-rate pricing?+
Yes — every quote is written and itemized by system component before any coring or excavation begins.
Will interior drain tile actually stop the water, or just hide it?+
It's a proven, code-recognized method for managing hydrostatic pressure, not a cosmetic fix that just moves the problem out of sight.
Do I need exterior excavation or can interior work solve it?+
Most seepage from hydrostatic pressure is fully addressable with interior drain tile — excavation is usually reserved for grading or membrane failures visible from outside.
What's the difference between a hairline crack and a structural one?+
We classify every crack during inspection; if it looks like it's still moving, we won't just inject it and call it done.
Is waterproofing work covered by a warranty?+
Yes, drain tile, sump, and injection installations all carry a written warranty against failure at the treated location.
How long does a typical installation take?+
Interior drain tile installations are usually completed in one to two days depending on perimeter length.
Do you work on older homes with existing foundation issues?+
Yes, older foundations are some of the most common jobs we handle, and our diagnostic accounts for aging materials and previous repair attempts.
What causes a basement to flood in the first place?+
Every property is different — our diagnostic identifies your specific combination of contributing factors rather than assuming a single cause.
Can you help with insurance documentation after a flood?+
We document extraction and mitigation work with photos, moisture readings, and timestamps you can include with a claim.
Do you offer emergency service outside business hours?+
A live dispatcher answers emergency calls at any hour — water damage doesn't wait for business hours and neither do we.
Can you work with my homeowner's insurance claim directly?+
Some clients ask us to speak directly with their adjuster about scope and materials, and we're glad to when it's useful for a claim already in progress.
Do I need to be home during the diagnostic visit?+
Yes, we ask that someone be present so the technician can walk the findings through with you directly before any recommendation is made.
What's the first sign I should call about, even if it seems minor?+
A musty smell that keeps returning, or a hairline crack that's new, are both worth a call before they become bigger problems.
Do you offer any kind of maintenance check after installation?+
Sump systems in particular benefit from an annual check, which we can schedule as a simple follow-up visit.
Will waterproofing work lower my homeowner's insurance premium?+
It varies by insurer, but a documented drain tile or sump installation is worth mentioning to your agent when you renew.
Do you offer financing for larger projects?+
Financing availability depends on project scope; smaller single-system jobs are usually straightforward flat-rate, while larger combination repairs sometimes qualify for financing.
How do I know if I actually need waterproofing or just better gutters?+
Poor gutter drainage is a common contributing factor, but it's rarely the whole story — our diagnostic checks both grading and foundation condition before recommending a fix.
Do you guarantee your work in writing, not just verbally?+
We put warranty coverage in writing specifically because verbal promises are hard to enforce months or years later when you actually need them.
What should I do right now if water is actively coming in?+
Move valuables away from the affected area if it's safe to do so, then call +1-866-476-1348 so extraction can begin as soon as a crew arrives.
