How to Hire a Siding Contractor

Exterior cladding protects your home's structure and insulation from wind, rain, and temperature swings. Choosing the right siding material and a qualified installer keeps your home energy-efficient and maintenance-free for decades. Vinyl siding is the most popular choice across the US for its low maintenance and competitive cost. Fiber cement siding (such as HardiePlank) offers superior durability, fire resistance, and a more authentic wood look. Wood, engineered wood, and stucco are regional favorites in certain climates and architectural styles. Most municipalities require a building permit for full siding replacement, and a reputable contractor will include permit fees in their estimate. What lies beneath the siding matters as much as the siding itself. Before new material goes on, contractors should inspect the existing house wrap or building paper — the moisture barrier between the siding and your wall sheathing. Damaged or absent house wrap allows moisture infiltration that can rot wall framing from inside, creating a far more expensive problem than the siding itself. Insulated vinyl siding adds rigid foam backing that improves your wall thermal performance. When comparing estimates, ask each contractor to specify the house wrap product, fastener type, and whether trim around windows and doors is included — these details separate thorough installations from shortcuts.

Typical cost

$8,000 – $28,000per project

Cost varies by home size, material choice, and whether existing siding and house wrap need to be removed. Vinyl siding runs $3–6 per square foot installed; fiber cement (James Hardie HardiePlank) $6–13; engineered wood $5–10; premium materials like steel or cedar run higher. Additional costs: house wrap replacement $0.50–1.00 per square foot, trim work $500–2,000, disposal of old siding $300–800, permit fees $150–400. Multi-story homes add scaffolding labor cost. Insulated vinyl adds 15–25% to vinyl cost but improves wall thermal performance. Get at least three written estimates specifying exact product, thickness, house wrap, and included warranties.

Hiring checklist

1Ask contractors to specify the exact product name, manufacturer, thickness, and finish in their bid.
2Confirm the bid includes removal of existing siding, disposal, and house wrap or moisture barrier.
3Verify the contractor is licensed and carries current general liability insurance.
4Ask about the manufacturer product warranty and the contractor's installation warranty separately.
5Confirm they pull the required permit from your local building department.
6Request references from similar projects completed in your area in the last two years.

Before you hire a siding contractor

Siding replacement is one of the larger exterior investments a homeowner makes, so contractor selection deserves care. Start by verifying that any contractor you consider is licensed — most states require contractors performing siding work above a minimum dollar threshold to be registered with the state contractor licensing authority. Ask for their license number and verify it is in good standing before scheduling an estimate. When evaluating bids, the product specification matters more than the price. Ask each contractor to name the exact siding product, manufacturer, thickness, and finish — not just vinyl siding or fiber cement. Different products within the same category carry different warranties and perform differently over time. A contractor who will not commit to specifics in writing is leaving flexibility you do not want them to have. Disposal of existing siding and house wrap inspection should both be addressed in the estimate. For larger homes or premium materials, check references from recent projects of similar size. Ask specifically whether the project finished on schedule and whether the crew left the site clean each day. Get at least three written estimates and make sure each specifies the exact product, house wrap product, and warranty terms so you can compare fairly.
