The national average for siding replacement ranges from $5,000 to $16,000 for a typical 1,500–2,000 sq ft home. Vinyl siding is the most affordable at $3–$7 per sq ft installed. Fiber cement (Hardie Board) runs $6–$13 per sq ft. Wood siding costs $8–$15 per sq ft. The total depends on home size, siding material, and whether old siding needs removal.

Vinyl siding lasts 20–40 years with minimal maintenance. Fiber cement siding lasts 30–50 years and is resistant to rot, fire, and insects. Wood siding lasts 20–40 years but requires regular painting and sealing. Engineered wood siding lasts 20–30 years and is more affordable than natural wood.

Fiber cement (Hardie Board) is widely considered the best overall siding material — it's durable, low maintenance, fire resistant, and looks like wood. Vinyl is the best value for budget-conscious homeowners. Wood offers the best natural aesthetics but requires the most upkeep. The best choice depends on your climate, budget, and home style.

In some cases, yes — vinyl siding can be installed over old siding if the existing surface is flat and in good condition. However, most contractors recommend removing old siding first to inspect and repair the underlying sheathing, add insulation, and ensure a proper moisture barrier. Installing over damaged siding can trap moisture and cause rot.

Insulated siding can reduce energy costs by 5–20% by adding an extra layer of thermal resistance to your home's exterior. Insulated vinyl siding with a foam backing is particularly effective. Combined with proper air sealing, new siding can make a meaningful difference in comfort and energy costs.

A full siding replacement on a typical 1,500–2,000 sq ft home takes 1–2 weeks. Larger homes or complex designs (multiple stories, many corners, trim details) may take 2–3 weeks. Weather delays are the most common cause of extended timelines.
