At Master Service Group, we pride ourselves on providing the full gamut of restoration services to both residential and commercial customers in a high-quality and ethical manner. Since the founding of this company, we’ve never been ones to stay complacent – and we’ve made it out mission to continue to learn and evolve with how we perform work as new information and technology becomes available. Our professionals are IICRC-certified and follow the latest industry standards when it comes to our offered services, and we’re constantly reading industry publications, attending industry trade shows, consulting with peers and seeking continuous education to further master our craft. We’re not one of those carpet cleaning companies who also offers water damage restoration services, we’re a restoration company that exclusively provides restoration work. In other words, we’re a restoration company for people who need restoration work, a company that’s investing in the latest technologies and equipment to better provide our services to you, our customers. It’s not uncommon to face obstacles in restoration projects, as the presence of asbestos, lead or mold can complicate certain jobs. Failure to properly handle these obstacles can lead to major health implications, which is why it’s important for such to be properly taken care of. We know how to handle these obstacles – and it’s because we take the time to carefully analyze and plan every project that we work on. Over the years, we’ve worked hard to assemble a team of engineers, architects, and environmental and safety consultants to be able handle all projects the right way, no matter how big or how small. As an accredited Better Business Bureau company, our reputation precedes itself – and it’s this great reputation that has helped us not just stay in business, but continue to grow. This was especially true of a time when so many others faltered at the height of the 2008 great recession. Property damage is never a situation t

"Jerry was not prompt at all with communication. Insurance company was looking for a more detailed estimate and breakdown of what was going to be done in each room to remove the mold and he refused. He didn’t want to spend the time to help me."

Mold Testing and Remediation questions, answered by experts

It’s worth it to get mold remediation as soon as you discover a mold in your home. Mold is a fungus that can be hazardous to your health and cause damage to your home and its belongings. Mold testing and inspections are the best way to know if you have a mold issue in your house. Once detected, call a professional mold remediation company immediately to get it taken care of.

Wood stain is not considered toxic after it dries. The solvents in wood stain are what give off volatile organic compounds (VOCs), which are toxic, but these dissolve as the product dries, leaving behind a non-toxic product. When working with wood stain, you should always wear a respirator and rubber gloves to protect yourself, but once it dries fully, it’s not toxic, according to the manufacturer’s instructions.

Dog vomit slime mold is not toxic to humans, plants or pets. However, it can act as an allergen to people with allergies. Dog vomit slime mold is considered more of a cosmetic nuisance. However, it is beneficial to its ecosystem as it helps break down organic matter, releasing nutrients for plants.

Wood rot is not as dangerous as black mold. When comparing toxic black mold versus wood rot, black mold is a far more dangerous type of fungus for your health. When someone inhales black mold spores, it can cause severe respiratory issues. Although some people are sensitive to the spores found with wood rot, most people do not react if they inhale wood rot spores.

If you own a stereo microscope, you should be able to see the fibers. The stereo microscope often can perform magnification up to 50x. But unless you have experience viewing asbestos fibers, you may not know exactly what you are seeing. Some fibers are curly, while others are long and straight. Blue, brown, white, and gray colored fibers are all possible.
