How Much Does New Siding Cost in South Jersey?

Here is the honest answer up front: a full siding replacement on a typical South Jersey single-family home is priced by the “square” (100 square feet of wall area), and the total depends mostly on your material choice, how much wall you have, and what we find behind the old siding. Every range on this page comes straight from the SJCC price book, which we review and re-publish each spring — and every figure carries a tag naming that source, because a number without a source is just a guess. We serve Cherry Hill, Voorhees, Marlton, Mount Laurel and nine other South Jersey towns.

What does a whole-house siding job cost in South Jersey?

The table below shows whole-home installed ranges by material. “Installed” means tear-off, sheathing inspection, housewrap, flashing, the siding itself, trim, cleanup and disposal — the complete job, not just panels nailed up. These are ranges because no two houses have the same wall area, window count or hidden damage.

Material	Typical whole-home installed range	Source
Vinyl	[VERIFY: SJCC price book v1]	SJCC price book v1, reviewed each spring
Insulated vinyl	[VERIFY: SJCC price book v1]	SJCC price book v1, reviewed each spring
Fiber cement (James Hardie)	[VERIFY: SJCC price book v1]	SJCC price book v1, reviewed each spring

Ranges assume a typical single-family home in our service area. A small ranch and a large two-story colonial with gables and dormers can sit far apart inside the same material row. Your written proposal will show your actual measured wall area, so you can check the math yourself.

What is the price per square, by material?

Siding is priced by the square: one square equals 100 square feet of wall. A home with 2,000 square feet of floor space is not a 20-square job — wall area depends on ceiling heights, gables, and how much of the wall is windows and doors (openings get measured out, then the extra labor to flash and trim them gets added back in). Per-square pricing is how you compare one material against another on equal footing.

Fiber cement and engineered wood cost more per square than standard vinyl mostly because of labor: the boards are heavier, cuts are slower, and the manufacturer’s written instructions set clearances and fastening rules we follow to the letter VERIFY: James Hardie HZ5 install instructions, current rev.

What changes the price? The 10 cost drivers

Two neighbors can pick the same siding and get very different quotes. Here is what actually moves the number, in roughly the order it matters:

1. Wall area. Measured in squares. More wall, more material, more labor. We measure every elevation and show you the numbers.
2. Material choice. Vinyl sits at the affordable end; fiber cement and engineered wood cost more in both material and labor. Compare the materials.
3. Tear-off vs. overlay. Removing the old siding adds labor and disposal, but it is the only way to inspect the sheathing (the wood panels under your siding). Read when overlay is even an option.
4. Hidden repairs. Rotted sheathing or framing is priced per sheet or per linear foot at a unit price you approve in writing before work starts. Nobody honest can quote this blind.
5. Stories and access. Two-story walls, walkout basements and tight side yards mean more staging and ladder time.
6. Windows, doors and penetrations. Every opening needs flashing (thin metal or membrane that directs water out) and trim. More openings, more detail hours.
7. Soffit, fascia and gutters. Often bundled with siding. Rotted fascia must be repaired, not just wrapped — see why.
8. Trim scope. Basic J-channel costs less than built-up window casing or a full trim package. This is one of the biggest quote-to-quote differences.
9. House style details. Gables, dormers, bump-outs and stone or brick transitions all add cuts and flashing work.
10. Season and schedule. Material prices move with the manufacturers, and peak-season calendars fill up. We never invent fake deadlines — but a written proposal states how long its pricing is valid.

Why do quotes for the same house differ so much?

Because the scopes are different, and the total hides that. One quote includes tear-off, new housewrap, flashing at every opening, kickout flashing (the small piece of metal that kicks roof water out into the gutter instead of behind your siding), mounting blocks at every penetration, and a written workmanship warranty. The cheaper one may be panels over your old siding with the word “flashing” nowhere on it.

The fix is simple: compare line by line, not total to total. We built a printable 15-line checklist for exactly this — HIC registration, insurance certificate, tear-off, sheathing unit price, housewrap brand, flashing scope, cleanup, disposal, payment schedule and warranty term. Get the quote comparison checklist and make every bidder fill in the same 15 lines.

How does financing change the total cost?

Financing spreads the same project price into monthly payments through a third-party lender. You always see the full project price first — the monthly figure is just that price divided over the loan term, plus the cost of credit. We never quote “monthly payments” without the total beside them.

Here is the structure of a financing example. The figures are placeholders until our lender’s written terms are approved:
