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."

When you have mold, making the correct decisions right away is critical. Whether it’s mold in your home, school, place of work or apartment there are many factors to consider. Are you going to be involved in a Mold Lawsuit? Will you be seeking property damages? Is anyone sick from mold exposure? Will you be seeking medical damages? Will you need expert witnesses? If so, what kind? Do you just want to test to be sure your environment is safe? Do you need Post Mold Remediation Testing to ensure a good job was done? These and other factors are questions which need to be answered before any environmental testing starts. It’s important to know what your goals are and why your testing. Different goals require different environmental tests, i.e. medical damages & property damages require different environmental tests to prove your case in court. Tests that a common or inexperienced mold inspector would not

Mold Testing and Remediation questions, answered by experts

White mold is generally considered less harmful than black mold. While both molds can cause health issues, black mold is often more toxic due to the mycotoxins it produces, posing a higher risk, especially to sensitive individuals. However, any mold infestation should be treated seriously, and prompt remediation is necessary to prevent further growth and potential health problems.

While a professional can always help, there are some common plumbing culprits you can check yourself to see if you can find the sewer gas smell. For example, you should check your water traps, sometimes called P-traps and S-traps, which are located under sink, shower, and laundry drains. The wax ring beneath the base of your toilet, which creates a watertight seal with the plumbing, could also have gone bad.

One of the first signs of mold in an air conditioner is a musty smell. You're likely to notice the smell when the unit runs, from the air coming out of the vents or the unit itself. You may also be able to see mold growing on the unit, such as near the condenser coils or by the fan. In some cases, there may be visible mold by the vents.

Mold is very likely if you do not take action to fully dry your home within around 24 to 48 hours after water damage occurs. This can happen even faster in warm, dark locations with extensive water damage. In areas of the home that receive ample sunlight and only have slight moisture issues, it can take weeks for mold to appear.

Mold can grow on garage ceiling insulation, which is why it’s important to install a vapor barrier behind the insulation and keep the space cooled and heated as you would your living area. Doing so will more or less eliminate the risk of mold growing on your garage ceiling insulation. You can also install a self-draining dehumidifier to help remove moisture, or opt for a foam board insulation or spray foam insulation that won’t harbor moisture and mold.
