Why This Matters
The contractor you hire matters more than the siding material you choose. A great material installed badly will fail. A decent material installed properly will last decades. This checklist covers the 20 most important questions to ask any contractor before you sign. It covers licensing, insurance, warranty, references, and red flags that should make you walk away.

Frequently Asked Questions
Ask for proof of liability insurance and workers compensation coverage. If they cannot provide it, walk away.
Get at least three quotes from licensed contractors. Compare not just price but also scope of work, materials, timeline, and warranty.
Never pay more than 10 to 30 percent upfront. Full payment before work starts is a major red flag.
Look for a workmanship warranty of at least 5 years from the contractor, plus the manufacturer material warranty which is typically 25 to lifetime.
