Siding is one of the larger home improvement investments most homeowners make, and the range of quotes you’ll see can be wide. Understanding what drives cost makes it easier to compare bids honestly and avoid paying for things you don’t need, or skipping things you do.
What Drives the Price
The two biggest factors are material choice and the size of your home. Labor, removal of existing siding, and any repairs to the sheathing or housewrap underneath also add to the total.
Vinyl siding is the most common choice in South Central PA and the most affordable. Standard vinyl typically runs $4–$7 per square foot installed. Insulated vinyl, which adds an EPS foam backer for improved rigidity and a modest R-value boost, runs $6–$10 per square foot installed. For a 2,000 square foot home, that puts total project cost roughly in the range of $12,000–$20,000 depending on the product and complexity of the job.
Fiber cement siding, including products like James Hardie, runs $8–$14 per square foot installed. It’s heavier than vinyl, requires more labor, and needs repainting every 10–15 years, but it’s harder, more fire-resistant, and holds paint exceptionally well. Total project cost for a typical South Central PA home runs $18,000–$30,000 or more.
Engineered wood falls roughly between vinyl and fiber cement on cost, typically $7–$12 per square foot installed, and delivers a more natural appearance than vinyl without the maintenance demands of real wood.
What Else Affects Your Final Number
Old siding removal adds cost, typically $1–$2 per square foot, and is almost always worth doing rather than residing over existing material. Installing over old siding traps moisture, hides potential damage, and can void manufacturer warranties.
Sheathing repairs, housewrap replacement, and trim work around windows and doors are often necessary on older homes and should be itemized in any honest quote. If a bid seems unusually low, ask specifically whether these items are included.
Home complexity matters too. More corners, gables, dormers, and irregular surfaces mean more cutting, waste, and labor time. A straightforward ranch-style home costs less per square foot than a two-story colonial with multiple rooflines.
How to Evaluate What You’re Getting
Material quality varies significantly within each category. A CertainTeed or ProVia vinyl product is not the same as a builder-grade import, even if both are described as “vinyl siding” on a quote. Ask for the specific product name and look up the warranty terms before comparing prices.
