Every service your basement may need, from one local company with its own crews.

Basement waterproofing NJ: dry basement corner with new concrete, a drainage edge along the walls and a sealed sump pit

Basement Waterproofing

Recurring seepage can damage finishes and stored belongings. We bring the drainage path, sump pit and discharge together as one planned system instead of treating each wet spot alone.

Interior French Drains

Our specialty. Perforated pipe and washed stone below the floor catch groundwater along the foundation, with no digging around the outside of your home.

Battery Backup Sump Pumps

Heavy rain and power outages can arrive together. A battery backup gives your system another way to pump when the main pump stops.

Mold Remediation

Stopping a leak doesn't remove the mold it left behind. We remove what can't be saved, treat the area and fix the moisture that allowed it to grow.

Foundation Crack Repair

Leaking or widening cracks need to be sealed. We repair the crack and deal with the water pressure behind the wall.

Crawl Space Encapsulation

Exposed soil keeps feeding moisture under your floors. A sealed vapor barrier covers it, with drainage added where water needs to be managed first.

Basement Humidity Control

Even after leaks are fixed, basement air can stay damp. Humidex ventilation helps manage the moisture that's left, with no buckets to empty.

Why it matters

A drier, healthier basement starts here

A dry basement gives you more usable space and helps create a healthier home. Keeping moisture under control helps prevent mold, and managing groundwater reduces the water pressure against your foundation walls.

Most wet basements in New Jersey come down to water in the ground. Clay soil, high water tables and older block foundations give it plenty of ways in. See the EPA's guide to moisture in the home for why it matters.

How it works

Three simple steps to a dry basement

1

Find the cause

During your free inspection, we look at where water enters, when it appears and what's already in place to manage it.

2

Understand the repair

We explain what we found and what we recommend. You can review the work, ask questions and decide how to proceed.

3

Know what comes next

Before we start, we go over access, the work area and cleanup, along with the system and its warranty terms.

Questions

Basement waterproofing questions

Who should I call for water in my basement?

Call a basement waterproofing contractor who will find where the water is coming from before recommending a fix. We inspect for free. Call 1-800-957-0075.

Is basement waterproofing worth it?

If water keeps coming back, yes. A dry basement protects your belongings and finishes, gives you usable space and helps keep mold from taking hold.

What's the most effective way to waterproof a basement?

It depends on where the water enters. For water at the floor-wall joint, an interior French drain with a sump pump is usually the most direct fix.

Do you dig up the yard?

No. The interior systems we install are done from inside your basement, so your yard and landscaping stay untouched.

Do you waterproof finished basements?

Yes. We open only what's needed along the walls that take on water. Tell us about finished walls and flooring during the inspection.

Is the warranty transferable?

Yes. Our interior French drain systems come with a 30-year transferable warranty, so it can go to the next owner if you sell.

How much does basement waterproofing cost?

It depends on the problem and the system your basement needs. We give you a free estimate after we see it.

What areas of New Jersey do you serve?

We work in Union, Essex, Morris, Somerset, Middlesex and Bergen counties. Call us if you don't see your town listed.
