Ask around in Pontiac 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 MI, 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.
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.
Catching these signs early usually means a smaller repair bill and a lot less disruption to your home.
That persistent musty odor downstairs almost always traces back to trapped moisture somewhere in the wall or floor assembly.
Efflorescence, that white crusty residue on foundation walls, is water evaporating and leaving mineral salts behind.
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.
Puddling near the same wall section after every storm points to a specific, fixable entry point.
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.
Rust or corrosion on metal fixtures, HVAC components, or stored tools in the basement.
Every service below starts from the same diagnostic-first approach, whether the job is a small crack injection or a full exterior excavation.
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.
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.
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.
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.
We size dehumidification equipment to your specific crawl space volume rather than a one-size-fits-all unit.
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.
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 Pontiac.
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.
Regional crews are staged specifically to keep response windows tight across our Pontiac, MI coverage area, day or night.
Every quote breaks out material, labor, and equipment separately, delivered in writing before any drilling or coring begins.
A recommendation that doesn't follow a real diagnostic is just a sales pitch; ours are backed by actual readings taken at your property.
Every crew member holds waterproofing-specific licensure and completes ongoing training in drain tile, injection, and structural crack evaluation.
We stand behind installed systems with documented warranty terms included in your quote, not a verbal promise that's hard to pin down later.
Four clear steps, no shortcuts skipped along the way — here's what actually happens between your first call and a finished, tested repair.
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.
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.
Pricing reflects exactly what the diagnostic found, not a generic package.
We test drain tile flow, pump activation, and injection fill before the crew leaves the property.
What homeowners in Pontiac, MI are saying after calling us for Waterproofing.
"Had standing water after a spring storm and they had a full drain tile system installed within the week. Completely dry since."
"They showed us the actual crack on camera before recommending anything — nobody had ever bothered to look that closely before."
"Quote matched the final invoice to the dollar. No surprise line items once they opened up the wall."
"Battery backup pump they installed kept us dry through a multi-hour outage last winter. Would've flooded otherwise."
"Appreciated that they told us plainly our crack needed an engineer's eyes before injecting anything — didn't just upsell us."
"Crawl space encapsulation got rid of a musty smell we'd been dealing with for two years. Should've called sooner."
"They walked us through the moisture readings on the spot instead of just telling us to trust them. Made the whole decision easier."
"Sump pump replacement was done same-day after our old one failed during a storm. Genuinely impressed with the response time."
"We got three other quotes before calling them, and theirs was the only one that actually explained why our specific wall was leaking."
"Vapor barrier install in our crawl space was clean, fast, and the humidity reading dropped noticeably within a couple weeks."
