Why do contractor estimates vary so much?

Material quality, project complexity, local labor rates, and contractor overhead all affect pricing. A 30–50% variance between bids on the same project usually means different scopes — get line-item estimates and compare carefully.

How can I lower the cost without sacrificing quality?

Schedule during off-peak times (spring and fall are busiest for most trades). Get 3+ competing bids. Avoid making scope changes after work starts. Supply your own materials if you can find better pricing (discuss with contractor first).

Does homeowner's insurance cover this work?

Typically only if the damage is sudden and accidental (storm, fire, burst pipe). Routine maintenance, wear and tear, and improvements are not covered. Check your policy for specifics.
