"Very satisfied with the whole process. Gerald did an excellent job. Arrived punctually and observed COVID protocols. Explained clearly what he was going to do and how. Showed us preliminary findings, and obtained our permission to take samples for lab testing. We felt he listened to, and responded to, our concerns. Overall a very professional experience. We’ve now received the written report and feel we got what we wanted: an objective analysis of the problem and information we need to remedy it."

"Auston educated us on mold and mold removal. The information he gave was appreciated. He arrived on time and performed the mold remediation. Air samples were taken before and after the mold removal process. When the air sample tests came back from the lab, he went over the results with us. We are pleased with the results and the customer service."

"Prior to doing the job, Yosvin came out and took a sample of the ceiling for me so we could have it tested. Thankfully the results were that the popcorn ceiling did not contain any asbestos material. Yosvin and his crew were fantastic! Not only did they show up on time, but they also did an excellent job of removing the popcorn ceiling, and cleaning up after themselves prior to leaving. Everything went smoothly. I would recommend Yosvin and his crew to others."

"Mold testing was thorough but do not let them sell you on their remediation do-it-yourself kit without knowing exactly what you are paying for. The kit is non-refundable and sold by a separate company. They do not tell you that. They transfer you to who you think is another employee to advise about remediation and they are actually transferring you to a completely different company. I was very disappointed when I learned all that. That company does not send out an itemized list of what you paid for unless you ask for it. It has been four days and after spending close to two thousand dollars I have yet to know what I bought."

"If you have or even think you have mold/fungus issues in your home, Virgil Pelton is the man to call. Not only is he knowledgeable, and professional, he will hold your hand and help you to resolve your issue. I used his recommend remedial company and they were fabulous. He helped me every step of the way from the time I called him to when all was done and no more mold/fungus!! He is honest and reasonable. Please, anyone out there who may have mold issue PLEASE contact Virgil. You want the air tested before and after remedial work. To make sure there is NO more mold spores in the air. He answers any and all questions. And explains everything in detail. He is a very calm guy and he prayed for wisdom before work. And prayed after the final visit. Wow!! He is God sent for me. We dealt with this mold issue since 10/2020. We should have called him first and saved a lot of headache and money$$$."

"David became a friend throughout my mold remediation process. He truly cares about the customer and the issues they have with their home. Mold sounds scary and he knows there are many mold companies that use that to scare customers. He confidently accesses and eliminated mold issues. And fast. He tests before and or after and explains results. It is so nice to know that I now have a home that isn't making my family sick. David is worth the time and money. He is very reasonable in comparison to the many other bids I had. Wish I would have found him 10 years ago. If you have or just think you have a mold issue, call David immediately. He is worth your time. I had all mold concerns addressed that were in my attic, crawl and under tub. Peace of mind is what he gave me and my family. PS. I even had another reputable company come out and double check the attic only because they insisted and the hub spent 2 minutes in my attic and said David and his team did an amazing job. My attic looks and smells new. And I had a leak that David and I detected and I was able to get a roofer to take care of it. Thanks David."

"As far as I can tell they did a good job of removing the mold and drying out the area, but I can only see the above floor part not the crawl space. They did not remove the damaged, moldy siding on the exterior, but I believe they wanted me & my homeowners insurance to make an overall plan to do that part of the remediation before removing part of my siding. They could have provided more information in advance on how the process would go rather than spending so much effort 'making the sale.' Better communication and punctuality would have been appreciated. I don't know that cost of the service yet; I paid them $1000, which is my insurance deductible, and they submitted the rest of the bill to my insurance. I don't know yet if all will be covered."

"Fantastic company and an even better work crew. They did a complete mold remediation of our crawlspace. Removed existing insulation, did mold remediation, installed new insulation and insulated all of our duct work and replaced vapor barrier. Workers were professional throughout the entire process. Thanks Jo, will definitely recommend!!"

Mold Testing and Remediation questions, answered by experts

Air purifiers are meant to kill airborne mold, along with pollen and dirt. Air purifiers are a good option if you have allergies and need a whole-home solution, whereas dehumidifiers are best for naturally damp areas (like a bathroom). Consider getting an indoor air quality test to determine if an air purifier is right for you.

Mold is very likely if you do not take action to fully dry your home within around 24 to 48 hours after water damage occurs. This can happen even faster in warm, dark locations with extensive water damage. In areas of the home that receive ample sunlight and only have slight moisture issues, it can take weeks for mold to appear.

While home mold tests can provide a simple identification of mold presence, they lack accuracy and reliability. These kits may detect mold spores but can't pinpoint the source or identify the type. Professional testing, combined with an inspection, is more comprehensive and leads to actionable next steps. 

Services test for allergens, mold, VOCs, and carbon monoxide levels to ensure a healthy indoor environment.

Mold on window sills is common, especially in damp or poorly ventilated areas. Windows are prone to condensation, which creates the moisture mold needs to grow. Dust, dirt, and other debris on the sills can further feed mold spores. While it’s not unusual, it should be addressed quickly to prevent further growth and potential health risks.
