"Noah scheduled an estimator to come to my house 30 minutes after my phone call. Moises came and gave me a reasonable price. He was prompt and courteous. The next day Hiram and Orge came to do the work. They were prompt and friendly. They did an excellent job removing the mold. Brian called me to keep me appraised of what they did and how long they will be leaving the dehumidifier and other drying equipment in the garage. This company is prompt, professional, and courteous and did an excellent job. I would definitely use them again."

"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."

Mold Testing and Remediation FAQs, answered by experts

Mold grows at the fastest rate the environment it’s in will let it. The space between your vinyl flooring and the base flooring it’s on is a perfect environment for mold growth, allowing for rapid spread and contamination. Preventing this involves a proper installation of the flooring and constant humidity control.

Efflorescence itself won’t turn into mold, but it can cause moisture problems, which can lead to mold. It’s important to address an efflorescence problem as soon as possible, as mold can pose health risks and even compromise the structure of your home.

Sampling typically takes 1-3 hours, and depending on the provider, lab results are available within 2-7 days.

The spread of wood rot results in a physical breakdown of the wood’s cellulose and lignin, causing it to become spongy or brittle. This can lead to structural damage. Water won’t damage the physical structure of the wood, while mold can eat away at the material and cause structural damage over a much longer timeframe. When further considering water damage versus mold versus wood rot, all three issues can create a musty or damp odor in the area. All three can also cause discoloration of the wood.

Hazardous waste is waste that poses a threat to human or environmental health. This generally refers to waste that is flammable, corrosive, toxic, or reactive. To confirm if the waste you need to remove is considered hazardous waste, contact your local hazardous waste facility.
