How to Choose a Siding Contractor (Without Getting Burned)

The part that separates good siding jobs from disasters

Here's the thing most homeowners don't know: the panels you see matter far less than the moisture barrier you don't. Siding's job is to keep water out of your walls, and that depends on proper house wrap, flashing around windows and doors, and correct fastening. A crew that skimps on the barrier to underbid the competition can leave siding that looks perfect while your sheathing quietly rots behind it. So you're not just hiring someone to hang panels — you're hiring someone to protect your walls.

Red flags — walk away if you see these

• A large upfront deposit (more than ~15–30%) or a cash-only demand.
• No written, detailed contract naming the material, scope, and warranty.
• A bid far below the others — someone is skipping house wrap, flashing, or proper prep you can't see.
• Pressure to sign "today" for a discount that conveniently expires.
• No proof of license and insurance, or no verifiable local address and reputation.
• Vague answers about the moisture barrier — a pro will explain exactly how they'll keep water out.

Questions to ask before you sign

• "Are you licensed, insured, and bonded?" — then verify the license number yourself.
• "Do you carry workers' comp and liability insurance?" — so you're not liable for on-site injuries.
• "How will you handle the house wrap and flashing?" — the answer tells you if they know what matters.
• "Are you a certified installer for this material?" — e.g. James Hardie certification for fiber cement unlocks better warranties.
• "What's the workmanship warranty, separate from the manufacturer's?" — get both in writing.
• "Does the quote include tear-off, disposal, trim, and cleanup?" — so there are no surprise add-ons.
• "Can I see recent local jobs and talk to those homeowners?" — real references, not just photos.

Pro tip from our network contractors

For fiber cement (James Hardie) especially, ask whether the contractor is a manufacturer-certified installer. Certification signals training and often unlocks stronger, longer warranties — a free, easy way to filter for a serious pro.

Get three quotes and read the scope

Three written quotes isn't about the lowest number — it's about seeing who's honest. Line them up and compare the *scope*: tear-off vs. going over old siding, house wrap and flashing, insulation, trim, and cleanup. Two quotes $3,000 apart are often quoting two different jobs. Know what siding should cost and how the materials compare before you decide, and if your siding is failing, see the signs it's time to replace.
