"Excellent choice to remodel our bathroom in our 100 year old home. Everything was broken or worn out. We are a senior couple and wanted to plan for the future. I was very impressed with the project manager, foreman and workers. They were attentive, respectful and worked with great skill. They kept the vintage details we wanted, like the window and door frame. We installed a walk-in tub, which was unusual, but they did a great job with it. When problems arose, they always had an good solution, such as when the wall tile we chose turned out to be unavailable. They made good alternative suggestions to my ideas, such as a glass panel on the open side of the tub instead of the built-up wall I thought we needed (less space, easier to clean, and lets in more light). They handled all permits and observed all code requirements, like a new main electrical panel and lead paint abatement. The price was reasonable (I obtained other bids). I recommend them highly."

Percolation Tests questions, answered by experts

Asbestos is commonly found in certain older homes, depending on the time period in which they were built. Asbestos use in home construction began in the 1920s and peaked after World War II before being limited by legislation in the ’70s, so a house constructed in 1880 is unlikely to contain asbestos, while one built in 1950 is much more likely to. Research a home’s history to determine the time period when it was built and any renovations made since.

Clear the area for access and inform the testing team about the building’s history and renovations.

Asbestos fibers can stay airborne for 48 to 72 hours, depending on the home's ventilation. Fibers can linger longer in enclosed spaces with poor airflow. Because the fibers are microscopic, they can easily remain suspended, making them difficult to detect without professional equipment.

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.

Determining if vermiculite contains asbestos requires professional testing. Visual inspection alone cannot confirm the presence of asbestos fibers, as these fibers are so small that they are not visible to the naked eye. A certified asbestos inspector will collect samples of the vermiculite insulation and send them to a laboratory for analysis. Microscopic examination using polarized light microscopy (PLM) or transmission electron microscopy (TEM) is necessary to accurately identify asbestos fibers. DIY sampling is strongly discouraged due to the potential health risks associated with asbestos exposure.
