"Bob from SIS is a straight shooter, provides options, clear explanations and associated costs on the necessary steps to remediate the problem. Good communication, timely and professional. Pleasantly surprised with my experience with SIS and the contractor they recommended to do the work. Easy 5-star rating, not too common these days."

When you have mold, making the correct decisions right away is critical. Whether it is 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 is important to know what your goals are and why your testing. Different goals require different environmental tests, i.e. medical damages and property damages require different environmental tests to prove your case in court. Tests that a common, or inexperienced, mold inspector would not typically use or know to use.

"The mold testing is fine. The mold remediation company is very sketchy. Just buy some air purifiers."

"Lesson learned. Always get an estimate. BEFORE the work is done. At least a digital copy. Arrangements for the project were made, with some one named Lynn, for the company to send someone to complete the work. We were quoted over the phone 4500-5000 which included a mold test. A sub contractor with an entirely different company (National Mold Company) was sent. When the contractor arrived, he stated that the job would be much more simpler than first thought. This led us to believe that the job would cost less, no. All said and done, they charged $5500. All said and done, it's almost like no work was done. The stains and the smell are still there. Only one actual board was taken upon the attic room. The ceiling in the bedroom was primed and painted but are still visible and have a funky smell. At this point I'm going to. Do what we should have done; Do the job ourselves. Just now with $5500 less dollars in our pockets. A detailed receipt was not given even though it was requested."

Mold Testing and Remediation questions, answered by experts

Signs of mold under silicone caulk include discoloration or dark spots appearing through or around the caulk, a musty odor in the area, and visible growth on the surface of the caulk. Additionally, if the caulk feels soft or spongy, it could indicate moisture trapped underneath, which is a breeding ground for mold.

The negatives of a humidifier are the potential for mold growth due to high humidity levels, the up-front cost, and the energy requirements to run it. Depending on the state of humidity in your home, you may not actually see lower utility bills due to the humidifier running on a near-constant basis. 

Professional carpet cleaning can cause mold if the job is not done properly. There are two ways this can happen—if your carpet cleaner fails to dry the carpet properly, or if your carpet cleaner uses an excessive amount of water during the cleaning process. Mold can grow wherever moisture is present, so make sure you hire a pro who knows the process inside and out.

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.

Bad odors and actual, visible mold aren’t the only ways to tell if your floorboards are suffering from too much moisture. Everything from high humidity to direct contact with water can cause wood to buckle, warp, peel, and discolor. Spotting one or more of these signs could be a clue that you’re dealing with mold.
