"I needed heating ducts cleaned. The first company I called did not show up or call. I called The Works and they came the next day - gave me a price and job was completed. Very upfront with process and also did mold remediation. It's very seldom these days for someone to actually do what they say and also do a good job!!! I would recommend this company very highly!!!"

"Very good and he also advised me that some dry wall had mold on it and he removed that free of charge. I would recommend this person to anyone that needs his service. I also like the fact that it is family owned and he is training his boys to follow him and learn the trade."

"Drake and his helper were very personable, professional, and attentive. They noticed we had a black mold problem in the basement that we hadn't seen and proposed a solution to help us. The solution keeps our family safe and saves us some money. Would definitely recommend hiring them!"

"The work was completed12/17/10. I sent payment shortly thereafter. To date I have not received the post air sample results, copy of guarantee or any acknowledgment from from Guardian. I called Candy Harris and have no return call from her. I know it is the holidays but I still deserve some contact from calls and payment. I am going to attempt to contact them today. I am trying to refinance my home and this lack of communication is slowing the process beyond the deadline set by State Farm. I receive daily communication from State Farm and am upset I'm getting nothing from the people who did the work. I have questions that go unanswered"

"Very good. This was our first time having this done so we didn't know what questions to ask to get a complete estimate. Because of this they added extra services to ensure we would be happy with their work. Very polite and clean. Would definitely hire them again."

"We hired SAL to install new ceramic tile floors in our hall bath, master bath, & master hallway. They also put in new 3/4 cherry hardwood floors in my master bedroom. The craftsmanship was immaculate. He shows up on time, worked on my job everyday till it was done, cleaned up at the end of the day, & most importantly was very respectful to me & my family. I am so pleased with the work that I would recommend SAL to everyone!!!! Great work, great price, great guy!!!

Mold Testing and Remediation FAQs, answered by experts

Mold, VOCs, radon, carbon monoxide, and particulate matter are typically measured.

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.

Symptoms of sewer gas poisoning include nausea, dizziness, extreme drowsiness, and headaches, according to the Wisconsin Department of Health Services. Exposure to higher concentrations for long periods of time could also lead to unconsciousness due to a lack of oxygen, aka suffocation. If you think you’ve been exposed to sewer gas for a dangerous amount of time, seek medical care immediately. Do not return to the site of exposure, after you’ve received medical care, call a pro for help.

Most of the health problems associated with exposure to fiberglass insulation are short-term in nature. You may suffer from minor and temporary skin or eye irritation if you come into contact with it, and you may experience some sneezing, coughing, or breathing issues if you inhale fiberglass. Those with asthma and allergies may suffer more and longer. Though fiberglass was once a suspected carcinogen, there’s now no good evidence that exposure to fiberglass can cause lung cancer.
