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."

"My water heater had been out for several days!! One company listed on the heater were called. They came out and said it needed a specific part still under warranty. I just needed to pay for labor. I agreed. They came out the next day with the part. It was defective!!! Couldn’t find the part anywhere. Would need to wait two more days. Plan B. I called around and found Beaver Construction Co. to install a new one. Bid was excellent!!! Far below other bids. They installed a new Rheem Heater within 2 hours.

"Did an excellent job overall, Replaced the service line from meter to house. Arrived before schedule, started the job early, were very quiet and did not disturb the neighbors, or me! Had me inspect as they went along. Did not disturb existing old plumbing for our well,, or the PVC for the sprinklers. Would definitely use them again and have given another neighbor their contact info for possible future problem they are concerned about."

"I feel that I was very lucky have chosen Corsa Plumbing to do diagnose and replace 2 sewers for me. One in Lafayette and one in Pleasant Hill. Ray, was easy to work with and he did a great job of advising me on the existing problems and explaining what they would do to fix them. The camera inspection of the sewer line and the estimate were free. I was present when he did them. Both of the bids were fair, but do not include the cost of County permits. I will highly recommend you get a bid from Corsa Plumbing. You won’t regret it. You can hardly tell that the sewer was replaced Steve Walsh, retired Realtor and property manager for residential homes."

Percolation Tests questions, answered by experts

Depending on the size of your home, the inspection process could take a few hours or a few days. While inspecting your home, the asbestos specialist will take small sections of the potentially contaminated material. They will then send the sample to an accredited laboratory or the local health department for testing. 

The cost of asbestos testing depends on your location, the home's size, and the testing area's complexity. Plan to spend between $230 and $800 for testing. During testing and while handling potential asbestos, the specialist may wear protective gear, including gloves, overalls, appropriate footwear, and respiratory equipment.

Some pros may recommend covering a popcorn ceiling that tests positive for asbestos with beadboard ceiling planks or drywall. The cost to install a beadboard ceiling averages more than $5,000, but you likely will pay more than the average for the installer to deal with the asbestos safely. Installing a beadboard ceiling or new drywall will disturb the asbestos and release some microscopic fibers, so the installer will need to take precautions. 

Typical costs range from $300 to $800, depending on the number of samples and the professional's expertise required for comprehensive testing.

Asbestos testing is conducted by collecting samples from materials suspected to contain asbestos and analyzing them in laboratories for confirmed presence.

Damaged tiles can release asbestos fibers into the air. Anyone in the surrounding area who may inhale the fibers will have them settled in the lining of internal organs. Over time, it may lead to serious health conditions such as lung cancer and mesothelioma.

The only safe way to prevent these conditions is to avoid exposure to asbestos at all costs, even for a short period of time.
