Who We Are

Ask around across North Carolina, NC and you'll find Arrow Tight Waterproofing mentioned by name — not because of an ad, but because a crew showed up, found the real problem, and fixed it the first time.

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

Response speed matters as much as technique in this trade, which is why our regional crews carry sump pumps, injection resin, and extraction equipment on every truck.

Beyond the repair itself, we document every diagnostic finding with photos and moisture readings, so you understand exactly what was found and why a given system was recommended.

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.

If the basement smell comes back within days of airing it out, that's moisture, not just staleness.

White, chalky staining on block or poured concrete walls — a mineral deposit called efflorescence.

A door frame that's suddenly out of square, or a window that won't close flush, can point to foundation movement.

Visible cracks in the foundation wall, whether hairline or wider stair-step patterns.

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.

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

This is the most common permanent fix for hydrostatic pressure seepage — proven, code-recognized, and installed without exterior excavation. 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. Photos and measurements are logged before and after every injection for your records.

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. Backup systems activate automatically the instant the primary loses power or falls behind.

Wall Vapor Barrier & Structural Reinforcement

Dimple-board membrane installed against a foundation wall creates an air gap that channels incidental moisture down to a collection point instead of letting it wick into finished drywall. We explain the engineering rationale before recommending any wall reinforcement work.

Why North Carolina, NC Homeowners Choose Arrow Tight Waterproofing

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

Anyone can put a truck on the road and call it Waterproofing service; what separates a crew worth trusting is what happens once they're standing in front of your foundation.

1

Same-Day Response for Active Intrusion

We understand active seepage doesn't wait for a convenient slot, so emergency calls get dispatched immediately with equipment already loaded.

2

Written, Itemized Pricing — No Surprises

Pricing is based on what our diagnostic actually finds, not a generic per-square-foot estimate pulled out of thin air.

3

Diagnosis Before Recommendation, Always

Technicians are trained to identify the real entry point, not just treat the most visible symptom.

4

Licensed Specialists, Not General Contractors

Below-grade water intrusion work is a distinct trade, and our technicians are trained and certified specifically in it, not treating it as a side skill.

Frequently Asked Questions

High-intent questions we hear most from Waterproofing customers across North Carolina, NC.

How fast can a Waterproofing technician arrive in North Carolina, NC?+
Active water intrusion moves to priority scheduling, and most North Carolina, NC 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?+
Drain tile intercepts groundwater below the slab and routes it to a sump basin before it reaches the finished space — it addresses the water at the source.
Do I need exterior excavation or can interior work solve it?+
We evaluate both approaches during the diagnostic and recommend whichever solves the actual entry point with the least disruption.
What's the difference between a hairline crack and a structural one?+
A hairline crack is typically under an eighth of an inch and stable — a good candidate for injection. A structural crack shows displacement or is still widening and needs engineering evaluation first.
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?+
Exterior excavation projects take longer, typically several days, depending on wall section length and access.
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're not public adjusters, but our documentation is formatted to support whatever your insurer's claim process requires.
Do you offer emergency service outside business hours?+
Yes, emergency dispatch operates continuously for active flooding and failed sump pumps, including nights and weekends.
Can you work with my homeowner's insurance claim directly?+
We're not a public adjuster, but we document every job with dated photos and moisture readings formatted for insurance submission.
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?+
Some insurers do offer discounts for documented flood mitigation work — we can provide the paperwork, though the discount itself depends on your specific policy and carrier.
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?+
Call +1-866-476-1348 immediately — dispatch will walk you through basic mitigation steps while routing the nearest available emergency crew to your address.
