"Lazar diagnosed the problem from my description of the problem. He was spot on when he showed up the next day. I wasnâ t on site, he kept me informed at every step, sending video. The main sewer line was clogged, which caused periodic sewerage backups. Compounded by hair in the bathtub, sinks and shower. Within an hour he pulled out tree roots from the line and snaked everything. He then sent pictures of all things flushing and flowing. Extremely professional and reasonably priced. He and his team are plumbing whisperes, excellent technicians."

Percolation Tests questions, answered by experts

Knob and tube wiring is an older type of electrical wiring that's no longer used and generally not considered safe. However, some homes still have it, or may have a knob and tube wiring system that was incorrectly modified or rigged to work with a modern electrical system. Knob and tube wiring may contain asbestos insulation, but the only way to know is to have the material professionally tested.

A professional indoor air quality inspection takes anywhere from one to three hours, depending on the size of your home and the number of necessary samples. After the test, the specialist will discuss the findings, but you won’t get a full written report for 2 to 10 days, though you can ask your pro to expedite the process, if needed. 

Because of the danger of inhaling asbestos fibers, figuring out through testing whether your popcorn ceiling contains asbestos is definitely worth it. If the popcorn ceiling texture has asbestos, remove it as soon as possible to keep your family safe. Any home built in or before the 1980s that has popcorn ceilings could have asbestos, necessitating testing. Asbestos carries several health risks for people who inhale it, including the increased chance of developing lung cancer in the future.

Asbestos has not been used to manufacture new siding since the early 1980s. So, while asbestos is not currently used to make new siding, it can still be present in the siding of homes built before the 1980s. The best way to know if your siding has any type of asbestos is to have a professional test it.

The microscopic asbestos fibers do not cause eye irritation, throat irritation, or lung irritation. If you are inhaling fibers, you will not know it. This lack of immediate symptoms is one of the reasons why asbestos is so dangerous. You cannot know for certain if you are inhaling fibers, which is why you must wear safety gear if you could have any chance of an exposure while working.
