Doors that seal, lock, and look the part
Paragon Exteriors installs entry doors, sliding and French patio doors, and storm doors across Ocean County, Monmouth County, and the Jersey Shore, with most projects landing between $1,500 and $6,000 installed. Every door is set plumb and square, flashed and foam-sealed against wind-driven rain, and finished with fresh weatherstripping and an adjustable threshold — most swaps are done in a single day. We’re family-run, licensed (NJ HIC #13VH13814500), fully insured, and every estimate is free and itemized.
A door is a small project with an outsized job description: it’s the first thing guests touch, the last thing between your living room and a February nor’easter, and the lock your family trusts every night. We install for all three.
Entry, patio, or storm — what each one buys you
| Door type | Typical installed cost | Where it earns its keep |
|---|---|---|
| Steel entry door | $1,500 – $2,800 | The budget security workhorse — best kept a few miles inland, where salt air can’t rust its edges |
| Fiberglass entry door | $2,200 – $4,500 | The Shore favorite: wood looks without wood rot, immune to salt corrosion, insulates several times better than the solid wood it imitates |
| Sliding patio door | $2,500 – $5,000 | Maximum glass and light for deck and backyard access; modern low-E units end the “cold wall” effect of 1980s sliders |
| French / hinged patio door | $3,500 – $6,000 | The upgrade pick — wider clear opening, true divided-light character, multi-point locking as standard |
| Storm door | $500 – $1,200 (usually added to an entry project) | An air buffer plus rain shield for the door behind it, and a full-view screen when the sea breeze is worth letting in |
What “installed right” actually means
The door on the showroom floor is half the product. The other half happens in your opening, and it’s where cheap installs fail:
- Old unit out, opening inspected — soft or rotted framing at the sill corners gets cut out and rebuilt, not buried
- Sill pan flashing under the threshold, so any water that ever gets in drains out instead of into your subfloor
- Frame shimmed plumb, level, and square — the door latches with a fingertip push, no shoulder required
- Low-expansion foam sealing the jamb gap (stuffed fiberglass is a draft with extra steps)
- Full perimeter weatherstripping, door sweep, and adjustable threshold dialed to a light, even seal
- Stainless or coated hardware and hinges on homes near saltwater
- Exterior trim caulked and finished, old door and debris hauled away the same day
Salt, sun, and sideways rain
Jersey Shore doorways take punishment inland doors never see. Salt air corrodes steel skins, builder-grade hinges, and slider rollers years ahead of schedule. Summer sun on south- and west-facing entries fades finishes and warps wood slabs. And a nor’easter doesn’t drop rain on your door — it drives rain at it for 36 hours, probing the threshold and jamb seals the whole time. That’s why we spec fiberglass or vinyl-framed units near the water, corrosion-resistant hardware as standard, and sill pans on every install — the same storm-first thinking behind how we build coastal roofs for nor’easters.
If your current door whistles in the wind or shows daylight at a corner, you’re paying for that gap on every utility bill until it’s fixed.
Security you can measure
Most break-ins through doors don’t defeat the lock — they defeat the frame. A standard strike plate held by two 3/4-inch screws splits out of the jamb with one kick. Our installs anchor hinges and reinforced strike plates into the structural framing with long screws, hang solid-core or fiberglass slabs that resist flexing, and set deadbolts so they throw fully into the reinforced strike. On patio doors — the classic weak point — we install units with multi-point locks and laminated glass options, plus secondary security bars where you want them.
The fastest curb-appeal win on the house
Nothing changes a home’s face faster per dollar than the front door. A deep navy, black, or coastal red entry with matched hardware reads from the street like a full renovation — and it’s a one-day project. Many customers pair a new entry with replacement windows or fold it into a siding project so the whole front elevation lands as one design. If windows are on your list too, our guide to what window replacement really costs in NJ gives you honest numbers before anyone rings your doorbell.
