How accurate is this cost calculator?
These ranges reflect national average prices homeowners actually pay, based on industry data. Your local market, home size, material choices, and project complexity can move the final price. Always get at least 3 written quotes before committing.
Why do contractor quotes vary so much?
Labor rates differ by region, overhead varies between solo operators and large firms, and material quality tiers change the price significantly. A quote 30–50% below the average is a red flag — it often means cut corners or missing line items.
Should I choose the cheapest quote?
Not necessarily. Compare what's included: materials, warranty length, timeline, and cleanup. The middle quote from a well-reviewed contractor is usually the best value.
