What do I have to do to stop mold from growing again? Do I have a leak and where is it coming from? How bad is the smoke and soot damage? What do I need to do to remove the odor from my home? We can help you answer all of these questions! Whether you are in the middle of a crisis or not, we can Help! Call someone with 27 years experience as a General Contractor and 23 years of that time as a Fire, Water and Mold Emergency and Rebuilding Contractor with all of the proper certifications.

Here at Insight Environmental we are a full service inspection and testing/abatement company. With out experience and attention to detail we are a great choice for making sure you understand your property as well as making sure your property is safe. Call now for a consultation.

"Many people advised me not to contact a Mold Inspector, because â They always find moldâ . These are people who donâ t go to dentists because they might find cavities. The first time I hired Steve Ramos, he found â No Moldâ on the property I asked him to inspect so I knew I could trust him. This year I suspected I had mold in my rental property and wanted to be sure my pregnant tenant was safe. Steve not only found the source of mold, he told me exactly what type of mold I was dealing with, what the risks were to my tenant and unborn child, and what steps I needed to take to eliminate it. He was always available, and still is, to answer my questions and work with my contractor to insure a safe environment for my tenants and their baby. Nobody wants to have to call a mold inspector, but if you do, I urge you to call Steve Ramos. He is not only excellent on a professional level, he is also honest and caring on a personal, human level and goes way beyond his job description to help his clients."

Mold Testing and Remediation questions, answered by experts

You should not run an air conditioner with mold because it could spread the spores throughout your home. Mold exposure can trigger several health problems, including coughing, wheezing, sneezing, itchy eyes, and a sore throat. Living in a moldy house can also increase your risk of other illnesses, including sinus infections, pneumonia, and bronchitis.

Symptoms of sewer gas poisoning include nausea, dizziness, extreme drowsiness, and headaches, according to the Wisconsin Department of Health Services. Exposure to higher concentrations for long periods of time could also lead to unconsciousness due to a lack of oxygen, aka suffocation. If you think you’ve been exposed to sewer gas for a dangerous amount of time, seek medical care immediately. Do not return to the site of exposure, after you’ve received medical care, call a pro for help.

In some cases, black stains on brick are caused by organic substances like algae and mold. However, it's more likely that the black spots you're noticing on your bricks come from carbon from vehicle exhaust or soot. Black stains can usually be removed by scrubbing the brick with a brush and masonry cleaner or power washing.

The purpose of crawl space encapsulation is to prevent mold and moisture from entering your space. If your vapor barrier is properly installed and intact, it will dramatically reduce the chance that your crawl space develops mold. That said, moisture can condense in the area. If you notice excess humidity, you may need to install a dehumidifier to stave off mold and mildew growth.

If you’re unsure whether you have mildew or mold, you can hire a professional to test the material. The mold inspection cost can range from about $300 to $1,000, depending on the size of the growth area. Once the testing professional tells you whether you have mold or mildew, you can then take the necessary steps to get rid of it.
