Answers for planning your project

How is interior door installation priced?

A reliable interior door installation price requires a written, project-specific scope. Paragon Exteriors publishes NJ HIC registration 13VH13814500 for contractor verification. Materials, access, permits, and observed site conditions are reviewed before the final amount is confirmed, so this page does not apply one unsupported price to every property.

What is the interior door installation planning process?

The interior door installation process starts with a documented site review and written scope. Paragon serves Ocean, Monmouth, Middlesex and Burlington Counties, New Jersey. The proposal should identify materials, access, permits, responsible trades, and scheduling conditions before work begins, while project dates remain subject to scope, delivery, weather, inspections, and crew availability.

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

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.

Interior Door Installation questions, answered

How much does it cost to install an interior door 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 door for sound and quality, a barn-door setup, or a custom size that needs the opening reframed. New casing and hardware add to it. Doing several doors at once lowers the per-door cost. Your estimate breaks it out per opening.

What’s the difference between hollow-core and solid-core doors?

Hollow-core doors are light and budget-friendly but transmit sound and feel flimsy. Solid-core doors are heavier, quieter, and feel substantial — worth it for bedrooms, bathrooms, and offices where sound matters. We’ll walk you through where a solid-core upgrade is worth the difference and where a hollow-core is fine.

Can you replace just the door slab, or do I need a whole new frame?

If your existing frame is square and solid, we can often hang a new slab on the existing jamb and save you money. If the frame is out of plumb, damaged, or you’re changing the door size or swing, a pre-hung unit — slab and frame together — gives a cleaner, longer-lasting result. We assess each opening and recommend the honest option.

Do you install barn doors and closet doors too?

Yes — sliding barn doors, bypass and bifold closet doors, and pocket doors are all common jobs. Barn doors need solid blocking behind the wall to carry the track weight, which we install properly rather than anchoring to drywall. We handle the hardware, alignment, and trim so it slides smooth and looks intentional.

How long does interior door installation take?

Project and cleanup timing depends on scope, product delivery, weather, access, inspections, and current crew availability. The written proposal states the expected schedule.
