"It went very well.  I contacted him initially in late November.  He was busy and so was I so we scheduled the work for 12/28.  That day he called early to tell me he would be a little late.  He arrived and went right to work.  He tore off our old wallpaper and removed the under layer.  Then he applied a coat of plaster to the entire wall.  He applied it very smoothly so there was no waste and little sanding needed.  He had us put a heater and fan blowing on the wall to dry it thoroughly.  He came back the next day and sanded the wall.  That only took about an hour.
He was thorough, quick and efficient.  I was happy with the work and would definitely recommend him to others.

Mold Testing and Remediation FAQs, answered by experts

Mildew and mold are not different—mildew is a specific type of mold and yes, it can become dangerous if left untreated. It would be amazing if we were all biochemists but because we most likely aren’t, it isn’t wise to assume any mold is mildew on sight alone. Harmless mold and toxigenic mold (which can be deadly) look very similar, so if you see any new mold that looks even a little suspect, call a mold professional immediately.

Water damage occurs when your property or items suffer damage due to excess and unwanted water or moisture. The water could be present due to a natural disaster such as a hurricane or a burst pipe—water damage can be caused by many things. If necessary, contact a local water damage restoration company.

Several factors contribute to the persistent growth of mold in vents, with excess moisture being the most common culprit. Consistent mold formation in vents indicates an ongoing moisture problem within the HVAC system or its surroundings, likely caused by condensation on cool surfaces in areas with high humidity. Moisture accumulation can also result from leaks in ductwork, inadequate ventilation, or insufficient insulation, creating an environment favorable for mold growth. Regular inspections, addressing potential sources of moisture, maintaining proper ventilation, and routine HVAC maintenance can help prevent the recurrence of mold in vents. If the issue persists, seek professional assistance to identify and rectify the underlying problems.

Yes, if there is mold in your drywall mud and you then use it to build walls in your house—or if mold develops in your set drywall, like it can in hot and humid areas—it can lead to illness. Mold in your drywall (or other parts of your home) can make existing respiratory conditions or allergies worse, and the effect can be more intense for those who have existing health issues or compromised immune systems.

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.
