"We decided to remodel our outdated bathroom, and McCormick Home Builders was a fantastic choice. Khaled and the team delivered high-quality work within the timeline and our budget. Every detail, from the tile work to the lighting, was beautifully done. They communicated well throughout, keeping us informed at every step, and the end result was truly a spa-like bathroom we can enjoy daily. We’d love to work with them again!"

"One of the paint estimators that I used mentioned that he thought I had mold on the ceiling. I wanted to make sure that there was no mold before I began the painting work. So I called The Mold Detective. I have never had an experience with calling a mold company before because I didn?t suspect we had it. They were very good, and I had good results with them. They gave me a certificate to show for sure that I had no mold. He was very thorough in all the work that he did and answered all my questions. He gave me a thorough report that I am comfortable to show if anyone asks for it. The price was a little stiff. They actually didn?t do any work other than check, and that did not take long. What I paid for maybe was for the report. I really thought that the price was pretty high. I would use them again in the future if necessary."

Mold Testing and Remediation FAQs, answered by experts

Black discoloration on your attic insulation may be caused by buildup from soot, dust, or dirt, which does not come with dampness or a musty odor. However, another cause of black discoloration on attic insulation is black mold, which has a musty smell and other signs of damage. If you’re unsure what black stuff you’re looking at, consult a pro to be safe.

It is generally not safe to live in a house with smoke damage, as even minor damage can pose long-term health hazards and structural risks. While it might seem safe temporarily depending on the severity, you should relocate if there is major damage or visible soot. Smoke smells and residue contain dangerous particulates and chemical compounds, including carcinogens, that are hazardous to breathe and can cause respiratory issues. These signs of damage are not always visible but can have dangerous short-term and long-term effects on your health, belongings, and your home's structural materials. You should not stay in the house until a trained professional from a smoke remediation or restoration company has assessed the damage and determined it is safe to return. Your insurance company may cover the cost of alternative housing while the professional work is completed.

Drywall can be toxic to the environment and to humans in some cases. As drywall breaks down in a landfill and comes in contact with other organic chemicals, it can create hydrogen sulfide gas or leach into the groundwater. Additionally, the CDC recommends methods for controlling the inhalation of drywall dust when handled. While the common ingredients of drywall—gypsum, silica, and mica—are naturally occurring, they can cause irritation in some humans.

Signs of mold sickness often manifest as respiratory issues, including coughing, wheezing, shortness of breath, and sneezing. You might also experience symptoms that resemble allergies, such as itchy eyes and sinus infections. Other telltale signs include skin irritations, persistent and unexplainable headaches, and mental confusion, often described as 'brain fog.' It's important to remember that mold can cause health problems even if it's not visible, as it can grow inside walls. If you are experiencing these unexplained symptoms, you may want to consider a professional mold inspection.

A funky smell is the first indicator that mold or mildew is present in your home. You may also notice that you or your household members are suffering from increased allergies or respiratory issues. You should check the most obvious areas first—like your bathroom or anywhere there might be leaks—and if you still can’t locate the source, look under the floorboards.
