Q: When we bought our home, we didn’t know the property has a septic tank, rather than a sewer hookup. Our agent also didn’t know, so she never recommended a septic inspection. Now that we’re planning to build an addition, we can’t get a permit because we don’t know the location of the septic tank. The title company says they are not responsible for this disclosure.

If the location of the tank interferes with your planned addition, it may have to be abandoned, and another tank may have to be installed, However, if sewer service is available at the street, installing a sewer connection will be a worthwhile upgrade to the property.



Q: Our new home is under construction. Unfortunately, the roof leaked during the last rains, and mold showed up on some of the wall and floor surfaces. Should the drywall, insulation and floor materials be replaced in these areas, or can the problem be corrected in some other manner?

A: Mold has become such a major concern in recent years that some insurance companies refuse to write homeowners policies for any home that has had a mold problem. Therefore, total removal of all affected materials is recommended. It would also be prudent for the builder to have a mold survey performed by a qualified expert so that you will have professional …….
