Water heater repair cost by part.
Typical Friendswood repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
Water heater repair in Friendswood, Texas typically costs between $150 and $700 for common repairs, plus a $75–$200 diagnostic fee. With a median home age of 37 years, many homes have aging units that may need frequent service.
