"Cornelio set an appointment the next day when I messaged to fix two faucets in our bathroom. He made a free inspection, gave us a very reasonable quote, and offered to work on the fix the same day. He explained to us how the cartridge in the faucets are clean and unclogged, but the faucet body from the cheap brand is clogged and not serviceable. He recommended replacement faucets that should last longer and serviceable. We appreciated his honesty and would ask for his service again!"

"Evan did a fantastic job for us. He installed a brand-new toilet and rebuilt the internals of another one, and it’s clear he really knows his trade. Everything was done carefully and professionally, and both toilets are working perfectly now. He showed up on time, communicated clearly about what needed to be done, and his pricing was fair and transparent. He left the work area clean, which we really appreciated. Evan is also a great guy to have around while the work is being done — very personable and full of great stories. It made the whole experience easy and enjoyable. If you’re looking for a plumber who knows his stuff and takes pride in his work, I’d definitely recommend Evan."

Percolation Tests questions, answered by experts

While a professional can always help, there are some common plumbing culprits you can check yourself to see if you can find the sewer gas smell. For example, you should check your water traps, sometimes called P-traps and S-traps, which are located under sink, shower, and laundry drains. The wax ring beneath the base of your toilet, which creates a watertight seal with the plumbing, could also have gone bad.

Asbestos-containing materials are not easily affected by water and do not disintegrate or dissolve when exposed to it. However, porous materials can deteriorate due to water exposure, leading to the release of asbestos fibers into the air. The settling of asbestos fibers can also occur as water makes them heavy, which reduces the risk of airborne exposure, though future disturbance of the materials could cause risk. Wetting asbestos-containing materials does not constitute safe removal, and the proper handling and disposal of asbestos materials should be left to professionals.

There are products that still contain asbestos, but they were typically installed decades ago. Common places where you may still find asbestos-containing materials are in siding, wrapped around ductwork, in older appliances (i.e., stove and gravity furnaces), and in floors. Asbestos was primarily used as an insulator, so anywhere in an older home where you lose heat is where you will most likely find asbestos.

Federal law doesn’t require homeowners to disclose the presence of asbestos in their home, but some states and local municipalities may require it. That is why it’s important to test an older home for asbestos and other health hazards before moving forward with a sale.

Through air sampling devices and surface swabs in key areas of concern.
