"The remodeling of my guest bath went very smoothly. I had few ideas as to what I wanted, but thanks to Nathan's design help, I was able to select the items that fit my concept. Many reviews talk mainly about the job and the results, but there is one important area that is often neglected: the working crew. Without exception his guys, besides being highly competent, were both respectful and considerate at all times. I strongly recommend this company!"

"I'd give Juan and True Blue Plumbing six stars or more if I could. Nobody ever wants to have to call a plumber because it means something has gone wrong, but I'm confident that when I call True Blue Plumbing, the job is going to be taken care of the right way. I've been using True Blue Plumbing for several years and I'm always very happy with the work they do. Juan and his team are quick, clean, friendly and honest. Juan doesn't overcharge and he'll tell you when something just needs a little adjustment rather than a full repair. He's always very transparent about what work he's doing, what parts he's using, etc. I'm totally confident whenever I call True Blue because I know that they're not going to try to take advantage of me. Full recommendation of Juan and True Blue Plumbing and Rooter."

Percolation Tests questions, answered by experts

If asbestos is present, professionals provide recommendations for safe removal or containment. Follow local regulations for handling.

You shouldn’t see a difference in your home’s value from your local property assessor if you have asbestos. Does asbestos affect home value when you are selling the home, though? If you are planning to sell the home, most jurisdictions require you to legally disclose the presence of asbestos to any buyer. Most buyers would have reservations about purchasing a home with asbestos, so they may offer less for the home. If you hire a pro to completely remove the asbestos, you do not have to disclose to buyers that the home once had asbestos.

Vermiculite insulation that comes from a particular mine before 1990 is likely to contain asbestos. This is particularly true in the U.S. However, not all types of vermiculite insulation contain asbestos. Since you can't detect the presence of asbestos without special equipment, it's best to assume that the insulation contains the dangerous mineral and to either leave it alone or hire a professional to handle it.

According to the Environmental Protection Agency (EPA), you should contact the following officials to report a case of asbestos exposure:

  • Asbestos subject matter experts in your state 

  • EPA regional office

  • Toxic Substances Control Act (TSCA) Assistance Information Service Hotline via mail, email, or phone

  • EPA’s Asbestos Ombudsman via phone or fax 

If present, abatement action, including removal, sealing, or enclosure, should be planned per local regulations. Proper consultation with a professional is key.
