Typical rates for underground leak detection service & water line maps filed by builder?

Hi Answers crew. I want to get an idea of the average cost/hourly rate of underground water pipe leak detection services, location would be the N.W. part of country (Western WA.) for a fairly straight forward residential property with no more than 40 feet of line to be located and checked.

If I choose to not have it professionally located I am wondering if the builder of this development/house would have had to file a water line map with the city or county planning office back in 1977? If I have a map I can then dig dig dig and attempt to locate the leak and then repair.

There's a company called "American Leak Detection" that is franchised throughout the United States. The employees are well trained professionals whose sole purpose is to do exactly what you are looking for. They detect leaks. They don't fix them, so no conficlt of interest here--they find them and then go on their merry way.

Most homeowners are a little shocked at their fees, but they are extremely thorough and stand behind their investigation with a written garauntee. The last two people I knew of that used them were charged $275 and $230. They check not only the building structure of a property, but also all water lines whether marked by the city or a builder, or not. In our two neighbor's homes, they were charged by the property site size and the time spent there was in the hours. Even though the property owners were asked to be in attendance as the leak detection was being done, the jobs were followed up with written reports and diagrams of where the leaks were found.

I hope this helps. I'm sure that other good companies are out there. Check with foundation repair companies for other referals since they often include leak detection as a before and after service along with foundation repairs and could advise you of reputable services. Good luck

Good deal! I'd replace the line for sure if it is clay piping OR if it has cast iron pipes in the line which will eventually rust out. Check lots of places as prices can go from $1500 to $10k! Report It
