"This review is for Master Services, Crawl Space and Foundation Repair in Knoxville, TN. phone # 8653453030 , [*** Link removed ***] . We had the pleasure of meeting Nick (Sales Inspector) and Brandon, Brandon, and Jacob (Installers). We hired Master Services on 2/16/21 (work done on 2/22/21) to install a WaterGuard sub-floor drainage system in our home in Greeneville, TN. Nick is a terrific salesman. He is professional and does not push any unnecessary work. Brandon, Brandon and Jacob (I believe Jacob was our installers name - sorry if not), did such a tremendous job. They worked quickly, efficiently, and made sure to keep our home free of mess. Overall we are very happy we hired Master Services and recommend them to anyone needing foundation repair."

"During the initial contact, I was impressed with the explanation of the testing process provided by the individual who answered my call. I was equally impressed by Mr. Robinson's step-by-step explanation while he set up the equipment to perform the test. He explained his licensing and the accuracy of the test that he was conducting. He was professional, efficient and possesses a great deal of expertise in his chosen field. He informed me when to expect the results of the testing and followed up with a phone call explaining the report in minute detail. Looking forward to working with Mr. Robinson for the next step in this process. Thanks again. -- Roger K"

The owner kept me informed of everything going on and was very knowledgeable about products and installation. I would definitely hire them again. Top rated in my book."

"The installation was a long uncomfortable day for everyonel, but the results were wonderful! 
They showed up on time but I had to loan them my drop cloth for the hallway.  The sales rep had said they'd block off the rest of the house from dust and that was not the case.  There was no escape from the noise of jackhammers and even two floor levels away things shook.  Partway through, we noticed that the ground floor above the basement was looking cloudy and we asked if there was a way to prevent the dust from continuing to move up the stairs.  They used our plastic sheets to tape off the doorways to dining room and living room, but by then it was really too late.  By the time they were done, and the dust had settled(literally, in this case) there was a grey film on every surface of the ground floor from gritty apples on kitchen counter tops to every nook and cranny of our window sills and mantles of the living room.  Baseboards, knickknacks, picture frames, light switches, fan blades, tops of my new kitchen appliances.
When I complained the next day to the company, they reduced our price to cover a housekeeping fee, but we still had a lot of work to do ourselves to set things right with all the dust, and my time was worth way beyond the cleaning fee.  My antique dining chairs needed to be vacuumed, wiped, and dusted and will probably always have a bit more grey to the padded seats than before.  I probably should have hired a professional and let them send a bill to Ameri-dry. 
The workers themselves were many.  They were polite, and very hardworking.  The stairway was not very easy to navigate leading down to the basement and they had to carry huge buckets of gravel in and then haul the cement chunks back out.  This took most of a day and if the noise was a hassle to us, it must have been  unbearable to them.  I didn't see that they wore hearing protection, so I wonder how well the company takes care of their workers. 
They hired an outside carpenter to replace the steps the following day.  He slid a board down from the top of the stairs which punctured the wall liner in one spot.  It's fortunate that it is conveniently hidden by the steps, but I know it's there and I was disappointed that they would be so careless.
We've had a few tropical storms and absolutely NO basement flooding, we had one or two times that the sump pump needed to be jiggled to get going and I found pieces of drain pipe plastic from their construction had washed into the sump pump well, so maybe it won't stick again.

"They did a great job. They solved all the problems I had with the chimney and it’s been working perfectly ever since. They also fixed a problem on the roof around the chimney; they replaced the wood around the chimney with a material that would never rot, so they fixed it even better than it was before. It took them a couple of days to do the work. They took care of all the cleanup as well. We've been real happy with them."

"Very well. Workers arrived promptly and worked steadily. They inspected for mold in my basement, removed duct cover where mold was found, built a new cover, applied mold preventive to the whole basement, and did an awesome clean-up, including vacuuming the whole basement. I was pleased that the job was done well and finished in a day. One worker returned two days later to sand the drywall, which had needed time to dry completely. I appreciate how they explained everything they were doing."

Mold Testing and Remediation FAQs, answered by experts

Checking for mold yourself is crucial, as catching mold in the early stages is ideal. Mold can appear green, brown, black, blue, or yellow. It can smell musty and can feel like velvet, leather, or cotton. 

Most often, mold grows near water damage. It’s best to inspect these places for signs of mold growth:

  • Basement: Look in corners, windows, carpet, closets, and around appliances. 

  • Bathrooms: Check around sinks, ceilings, and around toilets. 

  • Kitchen: Inspect around the sink, behind the refrigerator, and behind trash can.

  • Attic: Look near the insulation and near intake and exhaust vents.

It’s unlikely your leaves are a hazard, especially if you get to them while they’re dry. However, a couple of rare risks exist. University studies suggest that decaying leaves can produce organochlorines, toxic pollutants similar to man-made PCBs (polychlorinated biphenyls), so avoid keeping them in an enclosed area.

Also, leaves and compost may cause the growth of fungi that can cause diseases like histoplasmosis and aspergillosis, as well as mold spores that are unhealthy for human lungs. Again, severe issues are rare, but those with compromised immune systems or allergies to mold should wear face masks when directly handling leaves.

It is not advisable to shower in a bathroom contaminated with black mold due to the potential health hazards it poses. Inhaling mold spores during showering can trigger allergic reactions, respiratory issues, and skin irritations, especially for individuals with pre-existing allergies or respiratory conditions. Prolonged exposure to black mold can result in severe health complications. It is crucial to eliminate any black mold problems in your bathroom before continuing with showering to ensure a safe and healthy environment.

Silverfish aren’t a direct sign of a mold problem. But since they like dark, damp locations, they’re a very strong sign that mold problems could exist. That’s why it’s important to look for signs of mold while you are taking care of a silverfish problem, and fix any causes of long-term moisture in your house.

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.
