Who We Are

Ask around in Lexington 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.

Our field teams hold real Waterproofing credentials and are licensed in SC, with training that covers moisture mapping, sump system design, and foundation crack evaluation in depth.

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.

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.

A musty smell that returns no matter how often you clean the basement.

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.

Standing water or damp carpet after any significant rainfall.

A sump pump that runs constantly, or one that hasn't been tested in years.

A wall that bows inward even slightly is responding to soil pressure that isn't going away on its own.

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

Unexplained rust forming on tools or ductwork is often the first physical evidence of chronically elevated humidity.

Core Waterproofing Solutions in Lexington

We don't push a single product — every job starts with a diagnosis, then a recommendation matched to what's actually happening at your property.

Emergency Water Extraction & Stabilization

When water is actively rising, extraction comes first — high-capacity pumps clear standing water while we map exactly where it's entering. Extraction is never treated as the finish line — it's the first step toward a lasting repair.

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

We classify every crack before recommending a resin — injecting a still-moving crack just delays the real conversation about what's causing the movement. 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

We calculate your pit's actual inflow rate before recommending pump horsepower, since an undersized pump is one of the most common causes of preventable flooding. Cellular notification add-ons alert your phone directly if the system is ever triggered.

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 Lexington, SC 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

A recommendation that doesn't follow a real diagnostic is just a sales pitch; ours are backed by actual readings taken at your property.

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.

5

Written Warranty on Every Installed System

We stand behind installed systems with documented warranty terms included in your quote, not a verbal promise that's hard to pin down later.

How a Waterproofing 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

A written warranty and, where relevant, a post-storm follow-up check come standard with every completed installation.

Frequently Asked Questions

High-intent questions we hear most from Waterproofing customers across Lexington, SC.

How fast can a Waterproofing technician arrive in Lexington, SC?+
Active water intrusion moves to priority scheduling, and most Lexington, SC service areas see a technician within hours of the call.
Do you provide upfront, flat-rate pricing?+
You'll know the full cost before work starts; nothing gets added mid-job without your sign-off first.
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?+
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?+
We assess existing conditions carefully on older homes since prior DIY fixes sometimes mask the real problem.
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?+
We're glad to do a post-storm follow-up check after a significant rain event to confirm the system is performing as designed.
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.
