Water heater repair cost by part.
Typical Montgomery repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
In Montgomery, Illinois, water heater repair costs typically range from $150 to $650 for common repairs, plus a $70–$175 diagnostic fee. Labor rates reflect the local median income of $105,240 and the need for an Illinois-licensed plumber. Permits are required under the Illinois Plumbing Code, which can add to the overall cost.
