Who We Are

Ask around in Fond du Lac 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.

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

A basement filling with water doesn't wait for a convenient appointment, so our dispatch model is built around same-day response for active seepage in Fond du Lac.

We believe a homeowner should be able to see the evidence behind a recommendation, not just take our word for it — every diagnostic visit comes with documented findings you can keep.

Signs Your Foundation Is Already Fighting Water

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

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

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

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

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.

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.

Core Waterproofing Solutions in Fond du Lac

From emergency response to permanent structural fixes, here's the full range of work our crews handle in Fond du Lac.

24/7 Emergency Waterproofing experts in Fond du Lac, WI

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

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

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

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.

Here's what you're really getting when you call Arrow Tight Waterproofing for Waterproofing in Fond du Lac.

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

Same-Day Response for Active Intrusion

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

Diagnosis Before Recommendation, Always

Frequently Asked Questions

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

How fast can a Waterproofing technician arrive in Fond du Lac, WI?+
Active water intrusion moves to priority scheduling, and most Fond du Lac, WI 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?+
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?+
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?+
Warranty terms are included in your written quote before work begins, so there's no ambiguity about what's covered.
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?+
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?+
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?+
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?+
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.
