Know the Warning Signs

Don't Wait — These Signs Mean Water Is Already Winning in Kellnersville

Most basement floods don't start as floods. They start as these ignored details. If you see any of these in your Kellnersville property, schedule a free inspection before the damage compounds.

Efflorescence on Block or Poured Walls

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.

Horizontal or Stair-Step Foundation Cracks

Vertical cracks are often settling. Horizontal cracks in block foundations indicate lateral soil pressure — a structural emergency, not just a cosmetic issue.

Musty Odor After Rain Events

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.

Visible Seepage at Wall-Floor Joint

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.

Peeling Paint or Bubbling Drywall

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.

Sump Pump Running Constantly

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 Stains on Concrete or Block

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.

Cracks in the Floor Slab

Floor slab cracks that show moisture after heavy rain are almost always driven by sub-slab water pressure. This typically requires sub-slab drainage and sump installation to relieve the pressure permanently.

What We Do

Our Full Range of Waterproofing Solutions in Kellnersville, WI

Arrow Tight Waterproofing doesn't sell one-size-fits-all waterproofing packages. We diagnose the entry point, the pressure source, and the existing drainage condition — then we build the solution around what your specific property needs.

💧

Interior Drain Tile & Perimeter Channel Systems

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.

Our sub-slab drainage systems use schedule 40 perforated PVC pipe in a stone bed, designed to handle high-volume water tables.

🏗️

Exterior Foundation Waterproofing & Membrane Application

Full exterior waterproofing involves exposing your foundation to the footer depth, applying a crystalline or elastomeric waterproofing membrane, installing a geocomposite drainage mat, and placing exterior drain tile at the footing — the same specification used in new commercial construction.

This approach solves the problem at the source: water never reaches your interior wall surface.

🔧

Poured-Wall Crack Injection & Block Wall Repointing

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.

🌿

Full Crawl Space Waterproofing & Drainage Installation

We install a minimum 20-mil reinforced poly vapor barrier over the entire crawl space floor and seal it up the walls to the sill plate — then seal all vents, install a conditioned air supply or dedicated crawl space dehumidifier, and spec a sump system if groundwater is present.

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.

⚙️

Primary & Backup Sump Pump Systems for Kellnersville Homes

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.

Sump pump replacement is one of the most time-sensitive repairs in waterproofing — a failed pump during a heavy rain event means an immediate flood.

Basement Window Well Repair & Drainage Installation

We excavate and regrade window wells to the proper dimension, install a gravel drain bed with a perforated pipe tied into your perimeter drainage system, and apply waterproof flashing around the window frame — stopping the entry point at the source instead of managing it inside.

Egress window installations create a significant opening in your foundation wall, and sealing the rough opening properly is as important as the window itself.

Real Customer Reviews

Hear It From Customers Who Hired Us Across Kellnersville, WI

★★★★★

"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.I'd recommend them to anyone dealing with the same problem."

Michael R. Basement Waterproofing Client

★★★★★

"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."

Sandra T. Foundation Crack Repair Client in Kellnersville, WI

★★★★★

"I bought a house in Kellnersville, WI 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.That kind of result speaks for itself."

David K. Homeowner in Kellnersville, WI

★★★★★

"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.Highly recommend the whole crew."

Lisa M. Homeowner

★★★★★

"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."

James W. Emergency Waterproofing Client in Kellnersville, WI

★★★★★

"As a commercial property manager overseeing several buildings in Kellnersville, WI, 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."

Common Questions

Waterproofing FAQ — Answers From Arrow Tight Waterproofing Technicians

How do I know if I need interior or exterior waterproofing?

The distinction comes down to where the water pressure is coming from — interior drainage handles water at the cove joint and lower wall.

How long does a basement waterproofing installation take?

Interior drain tile systems typically take 1–2 days depending on perimeter footage; full exterior excavation runs 2–5 days depending on footer depth.

Will basement waterproofing affect my home's resale value?

A professionally waterproofed basement with a transferable warranty is a selling feature, not just a repair. It eliminates a mandatory disclosure item, removes a negotiation point for buyers, and makes finished basement space more credibly usable in appraisals.

Does homeowner's insurance cover basement waterproofing?

Standard homeowner's insurance policies generally exclude damage from groundwater seepage, which is classified as a "maintenance issue." Sudden and accidental water damage from a burst pipe or equipment failure is typically covered.

How much does basement waterproofing cost in Kellnersville, WI?

Waterproofing costs vary significantly based on the solution required, the perimeter footage, and the existing drainage conditions. Interior drain tile systems for a standard residential basement typically run $4,000–$12,000.

What is the difference between damp-proofing and waterproofing?

Damp-proofing is the asphalt coating sprayed on new foundations during construction. It costs the builder very little, is not rated for hydrostatic head pressure, and typically fails within 10–20 years.

Do I need to leave my home during waterproofing installation?

You generally don't need to leave. Interior drainage work involves concrete cutting (noisy for a portion of the first day) and we use dust barriers and HEPA vacuums at the saw.

What causes basement walls to crack?

Poured concrete cracks primarily from shrinkage during initial cure, differential settlement as soil compacts beneath the footer, and thermal cycling over seasons. Concrete block cracks most commonly at mortar joints due to differential settlement or from lateral soil pressure.

Can waterproofing be done in winter or during rainy weather?

Interior systems: fully year-round. The work is inside, unaffected by outdoor temperatures or rain.

How do I maintain my waterproofing system after installation?

A properly installed interior drainage system and sump pump system requires minimal maintenance, but that minimal maintenance matters. Test your sump pump every 6 months by pouring water into the pit.

Is crawl space encapsulation worth it if I don't have standing water?

Yes — and this is one of the most consistent findings in building science research. An unencapsulated crawl space with no standing water still pushes humid ground-sourced air into your living area through the stack effect: warm air rising out of the house pulls cool.
