"We recently did some spring cleaning throughout our entire house and used J&B solutions to haul away all our old junk. They responded very quickly when I inquired about a quote for their services and the quote I received was very reasonable for the amount of stuff I needed hauled away. These guys were very professional and efficient from start to finish. They dropped off the trailer when they said they would and we’re even understanding when I needed a little bit more time to fill up the hauler. Overall it was a pleasure working with this company and we will definitely be using them again when we need another junk or demo removal!"

"We had water damage that also led to a mold issue, and Alex from MacCraft helped us take care of everything. He and his team handled both the water damage mitigation and mold remediation, explained the whole process, and worked very professionally. They opened the affected areas, cleaned everything properly, treated the framing, and set up drying equipment until everything was fully dry. The team was respectful, clean, and very knowledgeable. I really appreciate the help during a stressful situation. I would definitely recommend MacCraft and Alex if you?re dealing with water damage or mold."

Biohazard Remediation FAQs, answered by experts

No. When dry, mold enters a dormant state. While “sleeping,” the mold won’t multiply, but when it encounters moisture again, it springs back to life, releasing spores. That's why it's crucial to not only control humidity but also actively eliminate mold to prevent its resurgence and further growth inside your home.

Window sill mold can be harmful, but the severity depends on the type. Common household molds like Cladosporium or Aspergillus can trigger allergies, respiratory issues, or worsen asthma symptoms. However, black mold (Stachybotrys) can produce mycotoxins that can harm your health. Even less toxic molds should be addressed promptly to prevent health risks and property damage.

Painting over mold is not an effective solution and can actually make the problem worse. Instead, it traps moisture, which allows mold to grow and spread beneath the surface. Mold must be completely removed before painting to ensure the problem doesn’t recur. If mold is painted over, it may eventually seep through the new layer of paint, causing discoloration and peeling.

Many caulk alternatives are safe for use in kitchens and food preparation areas, provided you apply them correctly and let them cure for the right amount of time. If you’re unsure about this step, call in a pro to do it for you. Silicone putty and caulk strips are often used around sinks and countertops due to their waterproof and flexible nature. Always choose products labeled as safe for kitchen use and follow the manufacturer's instructions for proper application and curing.

Mold thrives in high-moisture environments, whether that’s steady leaks or just high condensation. Around the house, common causes of mold include leaky pipes, a leaking roof, high humidity, poor ventilation, a damp basement, rotting food in the fridge, wet clothing and towels not hung properly for drying, a leaking foundation, and a leaky air conditioner.

And, of course, if your home suffers from flood damage, you stand the risk of developing mold in the aftermath. That’s why it’s important to act quickly at the first sign of mold.
