Who We Are

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

Every technician on our roster is Waterproofing-certified and licensed in KS, trained specifically in hydrostatic pressure diagnosis, drain tile installation, and structural crack classification — not general handyman work rebranded as waterproofing.

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

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

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

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

Sticking doors on the ground floor are one of the more overlooked signs of a shifting foundation.

Stair-step cracking in a block wall usually signals something more than simple concrete shrinkage.

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

If you can't remember the last time your sump pump was tested, that's worth addressing before the next storm does it for you.

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. Extraction is never treated as the finish line — it's the first step toward a lasting repair.

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

We classify every crack before recommending a resin — injecting a still-moving crack just delays the real conversation about what's causing the movement. Injection resin fills the full depth of the crack, not just the visible surface.

Exterior Excavation & Membrane Application

This is the most thorough fix available and typically carries the longest service life, though it's not always necessary depending on what the interior diagnostic finds.

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

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 Derby, KS 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.

It's easy to promise fast, honest Waterproofing service in an ad — the real test is whether that promise holds up once a technician is actually standing in your basement.

1

Same-Day Response for Active Intrusion

A basement actively taking on water moves to the front of the schedule — most Derby, KS service areas see a technician within hours, not days.

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

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

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

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.

On-Site Diagnostic Visit

You'll see exactly what the equipment finds — this isn't a sales walkthrough, it's a real inspection.

3

Written Quote & Scheduling

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

Frequently Asked Questions

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

How fast can a Waterproofing technician arrive in Derby, KS?+
Response time depends on distance from the nearest staged crew, but active leaks are treated as priority dispatch across Derby, KS.
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?+
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?+
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?+
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 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?+
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?+
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?+
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?+
If water is reaching your foundation wall itself, gutters alone usually aren't enough; we'll tell you honestly if a smaller fix like downspout extension would solve it.
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.
