Who We Are

Arrow Tight Waterproofing has spent years earning a reputation in Delphos for showing up when a basement is taking on water and not leaving until it's actually fixed.

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

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.

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

Most serious foundation problems start small and quiet — here's what to watch for before a minor issue becomes a structural one.

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

Chalky white streaks on your foundation wall are a visible sign that water has been passing through the concrete itself.

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

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

Standing water or damp carpet after any significant rainfall.

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

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

A hygrometer reading that stays above 60% no matter how much you run a dehumidifier usually points to an active intrusion source.

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

Our Waterproofing Services in Delphos

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

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

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

We size dehumidification equipment to your specific crawl space volume rather than a one-size-fits-all unit.

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. 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.

Call & Triage

Describe the issue — a damp wall, standing water, a musty smell — and dispatch routes the right crew with matching equipment.

2

On-Site Diagnostic Visit

A technician arrives with moisture meters, a wall camera, and a hydrostatic pressure gauge to identify the actual entry point, not just the visible symptom.

Written Quote & Scheduling

Pricing reflects exactly what the diagnostic found, not a generic package.

Installation & Verification

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

Frequently Asked Questions

Answers to the questions homeowners ask most before booking Waterproofing service.

How fast can a Waterproofing technician arrive in Delphos, OH?+
Response time depends on distance from the nearest staged crew, but active leaks are treated as priority dispatch across Delphos, OH.
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?+
Hydrostatic pressure from groundwater, poor exterior grading, a failed sump pump, or a combination of all three are the most common causes we diagnose.
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?+
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?+
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?+
Being present lets you see the moisture readings and camera footage firsthand rather than getting a secondhand summary.
What's the first sign I should call about, even if it seems minor?+
Efflorescence — that white chalky residue on concrete — is an easy one to miss but worth addressing early.
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?+
We work with a few financing partners for larger combination projects — ask your technician during the quote and they'll walk you through current options.
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.
