Long Island Exterior Co. (April 2026) prices vinyl at $4 to $8 a square foot installed, James Hardie at $8 to $14, and cedar at $10 to $18. Siding Long Island puts a 2,000 square foot exterior at $14,500 to $26,000 in vinyl and $32,000 to $62,000 in James Hardie.

The salesperson measures two walls, taps a tablet and turns it around, and the number is far above what the neighbor two doors down paid. Both numbers can be fair. Wall area, the material and what is hiding under the old siding account for almost all of the gap.
Siding prices per square foot, source by source
Installed prices, labor and material together, as each company publishes them:
| Source | Vinyl | James Hardie / fiber cement | Cedar |
|---|---|---|---|
| Long Island Exterior Co. (Apr 2026) | $4 to $8 | $8 to $14 | $10 to $18 |
| Siding Long Island, Massapequa (2026) | $4.50 to $8.00 | $8.00 to $14.00 | $12.00 to $22.00 (shake) |
| North Shore Roofing & Siding (Apr 2026) | $4.50 to $12.00 | $6.00 to $15.00 | $9.00 to $20.00 |
| Skyluxe Construction (Dec 2025) | $5 to $9 | ||
| Long Island Windows and Siding (Sep 2025) | $5 to $12 | $7 to $15 | $9 to $16 |
Vinyl clusters around $4.50 to $8 at the companies with the tightest ranges. Hardie sits at roughly double that, and cedar higher still. Two in-between options show up less often: Long Island Exterior Co. prices LP SmartSide at $7 to $12, and Siding Long Island puts engineered cedar (Maibec) at $12 to $18.
Whole-house totals by size and material
Per-foot prices only help once you know your wall area. Long Island Windows and Siding says a three-bedroom Long Island house has about 1,600 to 2,200 square feet of siding. These are the totals companies publish for whole houses:
| House | Vinyl | James Hardie | Cedar | Source |
|---|---|---|---|---|
| 2,000 sq ft exterior | $14,500 to $26,000 | $32,000 to $62,000 | $38,000 to $72,000 | Siding Long Island (2026) |
| 2,000 sq ft Suffolk home | $10,000 to $18,000 | Skyluxe Construction (Dec 2025) | ||
| 3-bedroom house | $10,000 to $24,000+ | $14,000 to $28,000+ | $18,000 to $32,000+ | Long Island Windows and Siding (Sep 2025) |
| 2,500 sq ft colonial | $30,000 to $55,000 | Good Guys Contracting (2026) | ||
| Mid-size house | $16,000 to $30,000 | Long Island Exterior Co. (Apr 2026) |
Siding Long Island adds that insulated vinyl on the same 2,000 square foot exterior runs $22,000 to $34,000.
The Hardie numbers spread the widest. Good Guys Contracting says labor alone on a quality Long Island Hardie job runs $8 to $15 a square foot, with materials adding $2.50 to $5, because the boards are heavy and slow to cut and hang.
Line items that land on top of the base price
| Item | Published price | Source |
|---|---|---|
| Removing and disposing of old siding | $1 to $3 per sq ft | North Shore Roofing & Siding |
| Removing old siding | $1,200 to $3,500 per job | Long Island Windows and Siding |
| Removing aluminum or asbestos shingle siding | adds $1.50 to $3.00 per sq ft | Siding Long Island |
| Certified asbestos abatement | $3,500 to $6,500 flat | Siding Long Island |
| Rotted sheathing or wall repairs, if found | $500 to $5,000+ | Long Island Windows and Siding |
| Trim, soffit, fascia and window capping | $3 to $6 per linear foot | Long Island Windows and Siding |
| House wrap with rigid foam insulation | adds $1,000 to $4,000 | North Shore Roofing & Siding |
| Dumpster, cleanup and misc. | $500 to $1,200 | Long Island Windows and Siding |
Asbestos is worth asking about on older Long Island houses with cement shingle siding, since Siding Long Island prices it as a separate job for a certified removal company. Rot is the one nobody can price until the old siding is off, so ask how the contract handles it: a per-sheet price for sheathing, written in before you sign, keeps the surprise small.
Nassau, Suffolk and the shore
Long Island Exterior Co. says siding labor runs about 8 to 15 percent higher in Nassau than in Suffolk on comparable jobs. We did not find a Long Island company publishing separate prices for the Hamptons or the North Fork.
Near the water the install itself changes. Good Guys Contracting says South Shore and East End houses in the high-wind zone often need face nailing and stainless fasteners, which adds labor.
Permits for re-siding, town by town
Contractors’ pages disagree on this, so we went to the towns. The Town of Islip’s 2025 permit guide says no permit is required for residential siding replacement unless structural elements are changed. Hempstead, Huntington and Brookhaven exempt ordinary repairs that do not touch the structure, but none of the three names siding, so the answer can depend on the job. Villages run their own building departments. Call yours before work starts, and if a permit is needed, Huntington’s code sets a $125 minimum fee for residential work plus a $50 application fee.
Getting from a range to your own number
Measure, or ask each contractor for their measured wall area in square feet, and multiply by the per-foot range for the material you want. Then add the line items above that apply to your house. If two quotes are thousands apart, compare the square footage first, then whether tear-off, trim and house wrap are included. Our siding page has the list of what a written quote should spell out.
Re-siding permits are a town question. Companies based in a town that has its own page are listed apart from this price guide.
