"They responded very quickly and sounded very knowledgeable. The test results were sent the following day. This is a minor thing but the inspector talked in technical terms which I did not understand. I wish he could have explained more. However, on the report I received all the technical terms were clearly defined in a way I could understand. A suggestion would be to provide the customer with the explanation of thes terms at the time if the inspection or talk to the customer in terms they can understand."

"My review is tiered because the overall service seems to run on tiers. The technician was great. Very personable and professional. 5 stars for his work. Your tests get sent to the lab. The lab explains the results and recommends a company for a DIY solution. This is where things start to fall apart. The company you get referred to has abysmal reviews and the sales pitch feels extremely predatory. That taints my opinion of the lab results which would be teamed up with a business they probably shouldn't recommend. We're planning on either an independent company locally to get a quote from for any remediations we will take or even see what home depot has to offer. In any event please read the reviews of BioCide, the company they will recommend you use. We're still not sure we even have a real problem if they are working together."

Dry-rot, Water or Pest Damage - Major Repair

Serving Hermann, MO and surrounding areas

Emergency services offered

"I am writing this review to let other homeowners know that if they are unfortunately in need of foundation repair that the best company capable of handling the job is Advanced foundation repair & replacement. I have a two story home. The entire back and side wall had settled over six inches ( a total distance of seventy five feet). At the side of the house we have a masonry fireplace that had settled significantly as well. Then owner Frank Matyiko hooked up his exclusive unified jacking machine. Frank provided us with a licensed structural engineer that stamped all fazes of construction. He assured me that our house would be a piece of cake. He was right. Advanced leveled the back of my house along with the fireplace with his unified machine. Not a crack in the house. Not a crack in the fireplace. His team was polite courteous and most importantly fixed our problem. Price: $13,500. Thank you Frankie!!!!!"

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

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.  

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.

Since most mushrooms are beneficial for your grass, and otherwise harmless, it’s not a good idea to kill them with fungicide. If you suspect you have a poisonous type of mushroom in your grass, you should consult a professional concerning mitigation. There are lots of types of mushrooms and most are perfectly safe.

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.

The flooring that is the least toxic is solid wood. Natural linoleum, tile, stone, bamboo, and cork flooring also make the list of least-toxic flooring types. These flooring materials are safer and healthier for your home because they are natural materials that aren’t manufactured with chemicals, unlike laminate flooring. While some laminate flooring brands are made with less formaldehyde, many contain high levels of toxic chemicals that can off-gas in your home for months and years after installation.

Choosing natural flooring materials that are easy to clean without chemical cleansers can also help keep your home safer.
