Can you get sick from a wet basement?

• <div><p>While water in your basement is unlikely to make you sick unless it’s coming from a sewage backup, mold is likely to start to grow in wet areas within 24 hours, and mold can make you sick. According to the <a href="https://www.cdc.gov/mold-health/about/index.html">Centers for Disease Control and Prevention (CDC)</a>, inhaling mold spores can cause allergy symptoms, including runny nose, itchy eyes, difficulty breathing, wheezing, and itchy skin. Individuals with pre-existing respiratory issues like asthma and immunocompromised individuals are at an elevated risk of symptoms when inhaling mold spores.</p></div>

How do I remove standing water around the foundation?

• <div><p>French drains and yard grading systems are two highly effective ways to fix standing water around the foundation. Since the French drain uses a perforated pipe covered by gravel, you won’t have to worry about water taking the soil away from your foundation. Meanwhile, yard grading levels out the ground to prevent water from gathering around your foundation.</p></div>

Can you add a bathroom to an unfinished basement?

• <div><p>Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.</p></div>

"I misunderstood that Bio Safety was NOT going to complete repairs; instead, they ripped out carpet and drywall, primed areas they didn't rip out with mold resistant primer, and left me to hire a handyman to complete drywall and ceiling repairs. His crew couldn't answer many questions, and some answers were guesses which the owner contradicted when asked later. I asked the Bio Safety to check the attic but I was told that wouldn't be necessary. Instead, the handyman went into the attic and found more mold, a leak in the roof and other issues which he repaired immediately."
