We have been in the construction industry for over 10 years. From building ADUs, high-end kitchen remodels, bathroom remodels and home extensions, we have done just about everything under general construction. Our company prioritizes safety, quality and transparency.

"Me and my wife decided recently to get our kitchen remolded. After some time searching for the right guys to do the job we settled on RG Construction. Richard, who is the owner, is a great guy and super informative. He never left any question unanswered or left us uncertain about anything. His crew works quick, and they pay attention to the tiniest detail. They absolutely are worth every dollar and I would recommend RG Construction to any homeowner, and I for sure will be giving them a call back for any work I need done in the future. Me and my wife are absolutely in love with our remodel."

"Tony and his crew were skilled, professional and did a wonderful job. When I listed the job on Angi, Tony responded within 20 minutes. He asked about the job, asked for some pictures and I had a solid quote within an hour. Our installation had some challenges and, instead of making these issues more complicated and jacking up the price like other contractors did, he quickly came up with sensible solutions at a fair price. The job was done in one day and our new tankless water heater is superb! I highly recommend Tony and Tankless Plumbing Solutions."

Percolation Tests questions, answered by experts

If you think you’ve touched asbestos, do not put on a mask. This is important because you may take the asbestos fibers on your hands on trap them in the mask. Make your way to a sink and wash your hands thoroughly. Remove any clothes and seal them in a bag, then take a shower. Call your doctor and let them know you’ve been exposed to asbestos, and make sure you see them as soon as possible. The reason you keep the clothes is in case anyone wants to confirm the presence of asbestos.

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 

Mold, VOCs, radon, carbon monoxide, and particulate matter are typically measured.

The presence of asbestos fibers in siding is a critical health concern, as they can be inhaled and lead to severe respiratory issues. Even if asbestos siding appears to be in good condition, it may become a danger if it deteriorates over time or is disturbed during a renovation project, as this can release airborne fibers. Exposure to these fibers is linked to life-threatening diseases like asbestosis, mesothelioma, and lung cancer.

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.
