"Going for a refi and the appraiser noticed mold on the ceiling in a bath. It's a vaulted ceiling. I needed to remediate the mold to close on the refi. I called Southside Mold Testing & Cleanouts and within a week, the mold was remediated. Brian and his crew were professional, prompt, and fair with pricing. Hope I never need this service again, but if I do, I would not hesitate to call Brian to do the work. What I thought was going to be a nightmare turned out to be pretty painless. Would highly recommend. Thanks!"

"I had a water heater leak that contaminated a 4x5 room with mold. RMS came over and thoroughly explained what they can do to fix it. They were punctual and also informative while they worked which made my wife comfortable with their work. The mold is gone and my family is safe. I would hire them again if ever needed."

"We have a cold room for adhesive storage and had a horrible case of mold due to an incorrect build out. I called these guys and they came out very quickly. They removed all of the mold along with infested ceiling tiles and paint the fell off of the wall during the process. They left the walls looking new again and cleaned their mess. We have not had a mold issue since. I highly recommend these professionals!"

"GCPRO were the most professional and technology-equipped of all the estimators who came to look at this project. They had laser measures, tools for reading how wet the drywall was, infrared cameras to look at the water saturation... It was impressive! They also were very competitive in pricing. I chose them for those reasons and because they were start-to-finish, handling the remediation and removal efforts all the way through to reconstruction and finishing efforts. The technology carried through those efforts as well, with 3D scanning to measure space and material requirements. The two carpenters who worked on putting everything back together (and actually beyond what was originally there, Janusz and Yaroslav, were extremely professional, polite, detail-oriented and neat. I am astounded by the quality of their craftsmanship. I cannot recommend GCPRO enough!"

Mold Testing and Remediation FAQs, answered by experts

Although you can run a DIY test for mold inside your home by buying a test kit, you won’t know whether the strain of mold is dangerous. The best way to test for mold in a home is to hire a professional who can determine the specific type of mold that you have. If you’re worried you exposed yourself to mold and it’s making you ill, you could request a health test. Your personal doctor could test your urine, take a nasal swab, or test some body tissue to determine your potential exposure to mold.

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.

Sewer gas in any location can cause eye and respiratory irritation if you’re exposed at low levels, or more severe symptoms if you’re exposed at high levels—but fortunately, the fresh air outside means it’s less likely to affect your physical health. However, sewer smells outside can still indicate significant plumbing problems that will need to be dealt with, such as a potentially damaged sewer line or roof vent pipe.

Slime mold will go away on its own within a few days to a couple of weeks. Generally, there is no need to use chemicals on this matter. If you want to get rid of it right away, rake over the slime mold and the surrounding area or hose off large patches of it.

EIFS has several disadvantages, primarily related to cost and moisture. The system tends to have higher upfront installation costs compared to other siding options, and repairs can also be expensive, especially if water damage occurs. A significant downside is its low breathability, which can trap moisture between its layers from either leakage or condensation. This trapped moisture increases the risk of developing mold and rot, which can lead to costly and extensive repairs if not addressed promptly.
