"I was convinced I needed multiple bids to make a choice, but the choice was really easy. Five Star Bath Solutions is locally owned, licensed and doesn’t sub out the work. Their prices are competitive and their customer service was easily the best of the bunch. They told me that they would be at home at 7:30am to install and they were right on time. In addition to the fantastic work, they were really careful to with how they prepped and cleaned up. You would have never even known they were here once they left. Kudos to Mateo for a well done shower."

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.

If you own a stereo microscope, you should be able to see the fibers. The stereo microscope often can perform magnification up to 50x. But unless you have experience viewing asbestos fibers, you may not know exactly what you are seeing. Some fibers are curly, while others are long and straight. Blue, brown, white, and gray colored fibers are all possible.

If you have an older electrical system with fraying wires and other signs of damage, removal may be the best course of action. When asbestos begins to break down, it's more likely to become airborne, increasing the risk of health issues when it's inhaled.

However, if the system is in good condition and doesn't have visible signs of wear or damage, leaving it alone may be the safest course of action. An asbestos abatement and removal professional can help you determine the best way to proceed.

Epoxying over asbestos tiles is generally considered a safe option when done correctly. Epoxy acts as a sealant, encapsulating the asbestos tiles and preventing the release of asbestos fibers into the air. The key is ensuring that the asbestos tiles are in good condition, firmly adhered to the substrate, and not damaged or deteriorating. This method is only appropriate for tiles that are undamaged and securely in place. If the asbestos tiles are already loose, damaged, or deteriorating, encapsulating them with epoxy may not be a sufficient solution, as it might not address the potential for ongoing asbestos exposure.

While it's possible to cover asbestos tile with carpet, it's not recommended. Encapsulating tile beneath carpet doesn't eliminate the health risks. Over time, the asbestos tiles could degrade, releasing fibers into the air and potentially contaminating the carpet. Disturbance during carpet installation or removal might also release fibers.
