"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!"

"This company is hands down one of the best company’s we’ve ever worked with. Selling our house, mold was discovered and Patrick and his crew handled it with ease. From the initial phone call to the projects, end, we felt extremely confident working with Patrick. He was knowledgeable and thoroughly explained the step by step process. The day of remediation, his crew was prompt and left the work area extremely clean. The company’s’ 5 year transferrable warranty is piece of mind and not standard in the industry. We highly recommend Mold Removal Solutions!"

"Overall was good for what the service is. The technician was a postal worker and home inspector. So mold test company appears to be brokers. Their pricing was competitive from other quotes I received but I honestly think it was pricey for time spent and what they do. But like I said the price was pretty standard from the companies I called, in my opinion. But the technician was attentive and knowledgeable, and friendly."

"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!"

"They came, they saw, and they conquered! I had a sewer back-up in the utility room of my home, and had put kitty-litter to help absorb backup. Although it initially helped, it created its own mess when even more had to be put down because of additional backup. To be honest, wasn't sure if HydroForce was up to the task, especially when they had to finish up on another day. But, HydroForce proved not only to be up to the task. but did an awesome job! They cleared, cleaned, and disinfected the floor and the surrounding appliances to the point they would be affected by the back-up. The only thing I did expect that wasn't done was the use of an air scrubber or purifier because of mold/mildew concerns with water backup. However, the job they did was impressive and I will recommend them for future use."

Mold Testing and Remediation FAQs, answered by experts

Some of the most common signs of sensitivity or illness from mold include congestion, eye irritation, difficulty breathing, and headaches. These symptoms may not lead to long-term health issues. However, some types of mold, like toxic black mold, can make you quite ill. You may experience respiratory issues, skin rashes, or neurological issues after exposure because of the toxicity. Infants, people with compromised immune systems, and older adults can suffer the most severe reactions.

Asbestos is absolutely cancerous. In fact, around 4% of all lung cancer cases are the result of asbestos exposure. This is why we recommend a full, professional removal and cleaning of any asbestos found in your home. If you are unsure whether there is any present, you should call a pro who will inspect your property.

Yes, professional testing identifies mold presence and type, guiding effective remediation plans that mitigate health risks. By ensuring thorough removal and preventing recurrence, professionals help maintain indoor air quality and reduce potential health hazards.

It is common for mold to grow around air vents, especially in areas with high humidity or moisture problems. These vents provide a perfect environment for mold to thrive due to the condensation caused by the meeting of warm and cool air. Mold growth can be accelerated by the presence of dust and debris around the vents. Regular maintenance, proper ventilation, and addressing any water leaks or excess humidity can prevent the growth of mold around air vents.

Yes, both mold and mildew can grow under outdoor rugs if they are exposed to water or humidity for a prolonged period of time. This is why frequently cleaning an outdoor rug and checking its state is important.
