"The work that Dave’s company performed was great with the exception of the living room, that ended up being mid-matched. Dave’s crew let me know that because of this they would paint the whole living room. They asked me to call and set up an appointment and I did. The day came and nobody showed up. I called Denise and she stated her crew called in sick and they were leaving town the next day. She would have Dave call me. He didn’t, so I txt him the following week and he called and said it would be more money, which it shouldn’t as I was previously told they mid-matched it so they would make it right. He was supposed to call later in the week and never did. I find though everyone was nice, the professionalism was lacking. I would not use again because of this."

Lead Testing and Removal questions, answered by experts

Lead testing prior to purchasing a property ensures that the new owners are informed about potential hazards, prevents health risks associated with lead poisoning, and facilitates timely remediation.

Lead testing in residential properties involves collecting samples from paint, dust, soil, or plumbing and analyzing them in certified laboratories to accurately identify lead levels.

Properties should be tested for lead every 2-3 years, especially if they are older, have undergone renovations, or show deterioration of paint or interior finishes.

Some causes of brown well water—like excess tannins or dissolved iron—don’t pose a health risk. In other cases, harmful bacteria might be the culprit. If your well water has suddenly turned brown, it’s a good idea to use a home water test kit to get a better sense of what’s going on with your water. Consider calling a professional for an expert opinion before drinking the water and hoping for the best.

Lead toxicity comes from inhaling lead or consuming it. Before the 1980s, when the government banned lead from consumer use, it could be found in paint, plumbing, pipes, ceramics, and even gasoline. Lead paint is toxic for the same reason lead itself is toxic, which is why lead poisoning from paint presents the same as lead poisoning from water or food sources, with a slight increase in respiratory symptoms vs. digestive symptoms. Lead paint is most dangerous when it’s old and peeling, cracking, or otherwise disturbed. This increases the concentration in the air and, therefore, in breathable air.
