"This is an awesome company and their service were superior. After purchasing a home in Decatur and thinking that when I purchased this house that the mole problem was remediated. The company T.I.C. was to remove the mold and they did nothing but paint the walls, it was a cover up. I begin to get ill and I called Healthy Homes. Caleb, Peyton and their crew oh my goodness they were wonderful. They were professional, respectful and yet personable. They explained what they were going to do and they tirelessly worked to remediate my problem. They got the job done, they removed the mold and everything else that had mold on it. They cleaned up after they were done. If I could I would give them a rating of 10 star. I would highly recommend this company. I promise you, you will not be disappointed. If you want the job done right, hire this company. A big thank you to these guys and God's blessings. Classie H."

"I had issues with my landlord trying to get me to pay for the mold removal in our apartment. John came in and tested the mold for free and when he found that the mold was under the apartment not in it, he told the landlord that it was his responsibility not ours. He is amazingly professional and friendly. He is friendly and my children loved watching him as he walked around looking at different areas. I would have him inspect again in a heartbeat if I needed it. I highly recommend him for any mold job you may have."

"Very professional both on the phone to arrange appointment and in person at our home. Painting brick in one room and wanted professional eyes to examine the floor boards and utility closet where previously covered areas were exposed. If we ever have problems, we will certainly use 911 Restoration!"

"Great company to deal with, from the first phone call to the cleanup after the job. Honest, professional, on time, great work and a decent price. I could not find anyone within 50+ miles to do the entire job I needed (which involved mold remediation, paint scraping, joint repair, and water resistant sealing). I will probably use them again for other services."

Mold Testing and Remediation FAQs, answered by experts

Any unexplained smell in your house should be investigated. However, some home odors are "red flag" worrisome because they pose immediate health and safety risks. Odors should be taken seriously when accompanied by headaches, nausea, or lightheadedness. If you smell an egg-like aroma, this is probably natural gas. You should leave the home immediately, and  contact your gas company.  

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.

The most common sign of a carbon monoxide leak is the visible black soot marks on the walls near your wood stove. An excess accumulation of smoke in other rooms of your home could also indicate that your wood burning stove is leaking carbon monoxide. If you notice either of these signs or are still unsure, it’s best to leave the premises and contact your fire department to check your home’s levels. 

Results typically come back within 48 hours, allowing for prompt remedial action.

Knowing what to expect during a mold inspection can help make the process easier. Prepare by closing doors and windows for 48 hours, turning off HVAC systems for at least two hours, and avoiding disinfectant chemicals for at least 48 hours. 

The mold inspection process takes between 24 and 48 hours. Your professional will check walls, fireplaces, air ducts, vents, and windows for visible spores. They will also take an outdoor base air sample. Your pro will send these samples to a lab for testing and advise you on the findings.
