Why Choose Us

Four Reasons Our Basement Waterproofing Clients Don't Call Anyone Else

Basement waterproofing mistakes usually come down to one thing: fixing the symptom instead of the source. A contractor who paints over a wet wall without checking cove joint condition or exterior grading is setting you up for the same call again in a year or two.

1

Licensed & Insured Crews

Every technician carries full state licensing and liability coverage before they ever step into your basement.

2

Same-Day Local Dispatch

Our Union, NJ crews are staffed locally, so a wet basement call doesn't sit in a national queue for a week.

3

Flat-Rate Pricing, No Surprises

You get one written number before drilling starts, covering drain tile, sump basin, and discharge line.

4

Moisture-Mapping Equipment

Thermal imaging helps us confirm whether a stain is active moisture or an old, already-fixed leak.

What We Do

Comprehensive Basement Waterproofing Solutions in Union, NJ

We scope every Basement Waterproofing job in person before quoting it, since two properties with the same symptom rarely need the same fix.

Basement

Interior Drain Tile

We route drain tile beneath the existing slab line so flooring disruption stays minimal during installation.

Basement

Sump Pump & Basin Installation

Every drain tile system needs a properly sized sump pump — we calculate basin size and pump horsepower from your square footage and local water table depth.

Basement

Wall Crack & Cove Joint Sealing

Vertical wall cracks get epoxy or polyurethane injection depending on whether they're still actively weeping.

Basement

Vapor Barrier Wall Membrane

A dimpled plastic membrane behind any finished basement wall channels residual moisture down to the drain tile instead of trapping it behind drywall.

Basement

Window Well Drainage

Poor window well drainage is one of the most overlooked Union, NJ basement leak sources, and it's often the cheapest fix on the list.

FAQ

Frequently Asked Questions About Basement Waterproofing

How much does interior drain tile installation cost?

Every Union, NJ quote is itemized in writing so you can see exactly what drives the total.

Will you cut into my basement floor?

Yes — interior drain tile requires cutting a channel along the slab edge, which we patch with concrete once the system is installed.

How long does basement waterproofing take?

Larger basements or those needing extensive crack repair can take a bit longer — we'll give you a realistic timeline in the written quote.

Do I need a sump pump if I'm just sealing a crack?

Not always — an isolated, non-leaking crack can sometimes be handled with injection alone.

Is basement waterproofing covered by insurance?

Do you offer a warranty on basement waterproofing work?

Yes, every interior drain tile and sump installation comes with a written warranty, explained in full before you approve the quote.

Our Services in Union, NJ

Union was incorporated as a township by an act of the New Jersey Legislature on February 17, 1853, from portions of Bethlehem Township. Clinton Town was formed on April 5, 1865, within portions of the township, and became an independent municipality in 1895. The township was named for Union Furnace, which was producing iron from 1742 until the 1780s. The name "Union" was chosen over the alternative "Rockhill", which was a community at the southern end of the township.
