Dry first. Pretty second.
The saddest call we get: a beautiful finished basement, two years old, ruined by one storm — because the finisher never touched the sump pump.
We're plumbers, so we start with water: sump pump health, battery backup, ejector pit for the new bathroom, drainage. Then we build the beautiful part on top of a basement that stays dry.
A basement bathroom needs an ejector system installed dead-right. That's a plumbing job — our job.
ADDED VALUE
A finished basement is the cheapest square footage you'll ever add.
No foundation, no roof, no addition permits — the structure already exists. You're buying finish work, and it returns value on day one and at resale.
Why finished basements fail — and how ours don't
★☆☆☆☆ THE COMPLAINT
“One storm, two years in — $60k of finished basement under 4 inches of water.”
✓ OUR FIX
Water first, always: sump health check, battery backup, drainage plan — before one stud goes up. We're plumbers; dry is our specialty.
★☆☆☆☆ THE COMPLAINT
“The basement bathroom always smelled. Turns out the ejector pit was done wrong.”
✓ OUR FIX
Sealed, vented, properly-sized ejector systems installed by licensed plumbers — the exact work basement finishers usually can't do themselves.
★☆☆☆☆ THE COMPLAINT
“No permits. The town made us open the ceiling to inspect everything.”
✓ OUR FIX
Permits and inspections on every basement — framing, electric coordination, plumbing — filed and passed before the drywall closes.
PRICE CHECK · NORTH JERSEY 2026
$45K – $120K
typical fixed-price range
How we beat the big chains: Finishing chains exclude the pumps and bathroom rough-ins that matter most. No franchise fees, no commissioned salesmen, no rented subcontractors — that’s typically 15–30% under national-brand quotes for the same or better spec. Bring us any written quote and we’ll match the scope line by line.
