What does interior door installation cost in New Jersey?
Installed interior doors in Ocean and Monmouth County typically run $350–$1,200 each, depending on whether it’s a hollow-core builder door, a solid-core upgrade, a barn-door setup, or a custom size that needs the opening reframed. New casing and hardware add to it, and doing several at once lowers the per-door cost. Your estimate is itemized per opening.
The detail that makes a house feel finished
Doors are the trim-carpentry detail people feel before they notice — a door that binds, a gap at the top, casing with a bad miter. Hung right, doors close with a soft click, swing true, and make a whole hallway look intentional. It’s precise work: plumb the jamb, shim it true, set consistent reveals, and miter the casing tight. That’s the standard we hold.
What a Paragon interior door job includes
- Assessment of each opening — new slab on an existing jamb where it’s square, pre-hung where it isn’t
- Hollow-core, solid-core, barn, bypass, bifold, or pocket doors to fit the room and budget
- Solid blocking behind barn-door and pocket-door hardware — never anchored to drywall alone
- Plumb, shimmed, and reveal-set so every door swings and latches true
- New casing and trim mitered clean, caulked, and ready for paint
- Hardware — hinges, knobs or levers, and stops installed and aligned
- Old-door haul-away and cleanup
Part of the interior refresh
Doors pair naturally with new flooring or a full renovation — matching trim and hardware across a floor pulls the whole level together. Current third-party financing options may be available, subject to lender disclosures, terms, and approval. Paragon is not a lender and does not guarantee approval or a particular payment.
