Arrow Tight Waterproofing deploys certified waterproofing crews across New Haven, MI. We diagnose the moisture path, seal it at the source, and back every job with a written guarantee — no vague patches, no callbacks.


We've spent years responding to flooded basements and seeping foundations across New Haven, MI. What we learned is simple: most water intrusion problems trace back to three root causes — hydrostatic pressure, improper grading, and compromised foundation walls. We fix all three, not just the symptom you can see.
Every technician on our team is IICRC-certified and carries full liability coverage. We pull permits where required, provide moisture readings before and after every job, and stand behind our work with a written warranty that transfers with the property.
Most basement floods don't start as floods. They start as these ignored details. If you see any of these in your New Haven property, schedule a free inspection before the damage compounds.
White powder on concrete means water has been migrating through your wall. The mineral deposits are left behind when water evaporates after passing through the block or poured wall.
Vertical cracks are often settling. Horizontal cracks in block foundations indicate lateral soil pressure — a structural emergency, not just a cosmetic issue.
If your basement smells earthy or musty after every heavy rain, active water intrusion is feeding organic growth — likely behind the drywall or under the slab.
The cove joint — where the floor slab meets the foundation wall — is the most common water entry point in basement systems. Staining or pooling there means hydrostatic pressure is actively pushing in.
Paint and drywall absorb moisture vapor before you can see liquid water. Bubbling or peeling in a below-grade space is almost always a moisture problem, not a paint adhesion failure.
A sump pump that cycles every few minutes — or runs non-stop — is managing a groundwater situation your current system wasn't designed for. It will burn out, and the next flood won't wait for a replacement.
Rust streaks on foundation walls mean moisture is reaching and oxidizing the rebar or metal lath inside your block or poured concrete — water that deep is already compromising structural integrity.
Hairline slab cracks that weep during wet weather indicate hydrostatic pressure building under the slab. Left alone, that pressure will widen the cracks and lift sections of the floor.
Every moisture problem has a different source. We identify yours specifically before we quote anything — then we deploy the right system, not the most expensive one.
Interior drain tile systems collect groundwater at the footing level before it enters your living space. We saw-cut the slab perimeter, excavate to the footing, install gravel-bed perforated pipe, and tie it into a sump system with battery backup — so you stay dry even during power outages.
These systems don't fight hydrostatic pressure — they redirect it.

This approach solves the problem at the source: water never reaches your interior wall surface.
📞 Schedule an Exterior Assessment →We inject poured-wall cracks using a port-and-backer system: surface ports are installed at 8–12 inch intervals along the crack, the surface is sealed with hydraulic cement, and two-part polyurethane or epoxy is pumped under pressure from the lowest port up — filling the crack through its full depth.
For concrete block foundation walls showing horizontal cracking or inward bowing, we pair crack repair with carbon fiber reinforcement straps anchored at the floor and rim joist.
📞 Get a Crack Injection Estimate →Crawl spaces are the most overlooked moisture source in residential structures. An unencapsulated crawl space — even one that "never floods" — pumps humid air into your living area through the stack effect, raising indoor humidity, feeding mold growth in floor joists, and accelerating wood rot in your subfloor structure. Full encapsulation seals that air pathway permanently.
For crawl spaces with active water entry, we install a perimeter drain channel at the footer line, route it to an appropriate discharge point or sump.
📞 Schedule a Crawl Space Inspection →A sump pump is only as reliable as its installation and backup plan. We install primary pumps — typically 1/2 to 3/4 HP cast iron submersibles with a minimum 10-year rating — alongside battery-operated backup systems that activate automatically when your primary pump fails or power goes out.
For finished basements and properties with high groundwater, we recommend a dual-pump system: a primary submersible at normal operating level and a pedestal backup set two inches higher.
📞 Get a Sump System Quote →Basement window wells are one of the most underestimated water entry points in residential waterproofing. When the well drain becomes clogged or the well itself is sized incorrectly for your roof drainage load, water pools against the window frame and enters through the sill, the window-to-frame joint, or the block wall directly adjacent.
Egress window installations create a significant opening in your foundation wall, and sealing the rough opening properly is as important as the window itself.
📞 Book a Window Well Assessment →There are a lot of waterproofing companies in MI. Here's what separates the ones who fix the problem from the ones who fix the symptom — and why Arrow Tight Waterproofing consistently lands on the right side of that line.

📞 Call Now: +1-866-476-1348"The crew showed up within 3 hours of my call at 9 PM on a Tuesday. I had water coming in through a crack in my poured wall at the floor joint — had been watching it for two seasons and finally called when it started spreading. They installed an interior drain system along two walls and a new sump pit. The work took two days. I've had three major rain events since then — completely dry. Worth every dollar.Highly recommend the whole crew."
"I've had two other companies look at my foundation crack before these guys. Both gave me vague proposals and neither one could tell me exactly why I had water or where it was coming in. Arrow Tight Waterproofing came out, brought a thermal camera, and showed me on screen exactly where the moisture was concentrated. The polyurethane injection they did on the crack has held for 18 months now with zero seepage. That's the most competent inspection I've ever gotten from a contractor.That kind of result speaks for itself."
"I bought a house in New Haven, MI knowing it had a moisture issue in the crawl space — previous owners had put down a thin plastic sheet that was doing nothing. Arrow Tight Waterproofing encapsulated the entire crawl space with a 20-mil liner, sealed the vents, and installed a dehumidifier. Within two weeks my downstairs floors stopped feeling cold and damp and the musty smell completely disappeared. The technician walked me through every step before starting. No surprises on the invoice.Highly recommend the whole crew."
"We had a window well that flooded every time we got more than an inch of rain. The well was filling up and water was coming straight in through the window sill joint. The fix was a regraded well with a perforated pipe tied into our existing interior drain. The whole job took one day. The crew was professional, cleaned up completely, and the well has handled every storm since without an issue.That kind of result speaks for itself."
"Called Arrow Tight Waterproofing after my old sump pump failed during a storm and I had 4 inches of water on my basement floor. They answered at midnight, arrived within an hour, and had a temporary pump running within 20 minutes of showing up. Once the emergency was managed, they walked me through a permanent drainage system upgrade. That was 8 months ago — I've had 6 rain events including one significant storm and the basement has stayed dry.I'd recommend them to anyone dealing with the same problem."
"As a commercial property manager overseeing several buildings in New Haven, MI, I've worked with a lot of waterproofing contractors. Arrow Tight Waterproofing is the first one that showed up to the initial walk with a written inspection checklist and completed it on-site before quoting. Every other contractor just eyeballed it and sent a number. Their exterior membrane on the building we had done 3 years ago is holding perfectly with zero callbacks.Highly recommend the whole crew."
