How Long Does It Take to Replace Siding?
Quick Answer
1–3 weeks for a full siding replacement on an average-sized home. Vinyl siding is fastest at 1–2 weeks, while fiber cement and wood take 2–3 weeks due to more labor-intensive installation.
Typical Duration
Quick Answer
Replacing the siding on an average-sized home (1,500–2,500 sq ft of exterior wall) takes 1–3 weeks with a professional crew. The timeline depends heavily on the siding material, home size, and whether underlying sheathing or insulation needs repair.
Timeline by Siding Material
| Material | Install Time | Lifespan | Cost per Sq Ft (installed) | Maintenance |
|---|---|---|---|---|
| Vinyl | 1–1.5 weeks | 20–40 years | $3–$8 | Low |
| Engineered wood (LP SmartSide) | 1.5–2 weeks | 25–50 years | $5–$10 | Medium |
| Fiber cement (HardiePlank) | 2–3 weeks | 30–50 years | $6–$13 | Medium |
| Natural wood (cedar, redwood) | 2–3 weeks | 15–40 years | $7–$15 | High |
| Metal (aluminum or steel) | 1.5–2 weeks | 40–60 years | $5–$12 | Low |
| Stone veneer | 3–5 weeks | 50+ years | $12–$25 | Low |
| Stucco | 2–4 weeks | 50–80 years | $6–$12 | Medium |

| Weather interruptions | Variable |
| Lead paint abatement (pre-1978 homes) | 2–5 days |
| Removing multiple layers of old siding | 1–2 days |
What Happens During Removal
The crew begins by stripping the old siding, which typically takes 2–4 days for an average home. This is the messiest phase — a dumpster is placed on-site for disposal. Once the siding is removed, the crew inspects the underlying sheathing (OSB or plywood) and house wrap for moisture damage, rot, or pest damage. Any compromised sheathing must be replaced before new siding goes on.
Crew Size and Its Impact
| Crew Size | Typical Timeline | Best For |
|---|---|---|
| 2-person crew | 2.5–4 weeks | Small homes, tight budgets |
| 3–4 person crew | 1.5–2.5 weeks | Average homes |
| 5–6 person crew | 1–1.5 weeks | Large homes, tight deadlines |
When to Replace vs. Repair
Full replacement makes sense when more than 30% of the siding shows damage, when moisture has penetrated behind the siding causing sheathing damage, or when upgrading the home's energy efficiency with modern insulated siding. Spot repairs of a few damaged boards or panels take only 2–4 hours and cost a fraction of full replacement.
Hiring Tips
Get at least three written estimates and verify that the contractor carries liability insurance and workers' compensation coverage. Ask specifically about their approach to sheathing inspection and repair — a contractor who plans to install new siding over damaged sheathing should be avoided. Most reputable contractors offer a workmanship warranty of 5–10 years in addition to the manufacturer's material warranty.
