"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!!!"

"We recently moved into our home and had felt that the air quality was poor and the vents needed to be cleaned. We were experiencing new allergies and chronic congestion. Jami was excellent when explaining the services and pricing, Dillon and team worked very hard to clean our entire system. After the requested cleaning, they showed before and after pictures of each vent/main. Dillon discovered mold in the furnace and in basement vents. The team stayed later than expected to add sanitation and furnace cleaning. All at an extremely reasonable price. We notice a big difference in our air quality in our house! We all feel better and deal with a lot less dusting when cleaning the house."

"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 met SAL through a friend that he did some insurance work for.  We have a large kitchen with a huge island and always wanted to redo the floors.  As I was looking for tile for the floor I found glass accent tiles that I wanted to use on the back splash to tie everything together.  Needless to say our project just got larger. We struggled to find qualified contractors to do this work and because we spend so much time in our kitchen we wanted everything to be perfect.  From the first second we met with SAL we were totally comfortable and confident they could do the work to our expectations.  Sure enough the job was completed 4 days ahead of schedule and turned out PERFECT!!! I catch myself sometimes just staring at my new tile. I absolutely love it. I would recommend SAL to everyone. We also had them replace some windows & put up siding on the back of our house (cement siding).  SAL is honest & does everything he says he will do. Great job guys and thanks so much!!!

Mold Testing and Remediation FAQs, answered by experts

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.

Although mildew is less harmful than mold, that doesn’t mean it’s safe. Breathing in even small amounts of mildew can cause serious health complications, especially in those with weakened immune systems. If you find any mildew in your home and can’t completely remove it easily (and there are elderly or sick people living there) you should call a professional right away.

While the resistance of lime to mold is a hotly contested topic of debate, it is true that because it allows porous materials to breathe, it avoids trapping moisture close to the structure of a building. This breathability makes it less susceptible to mold than paint because it gathers less moisture.

Signs of mold sickness often manifest as respiratory issues, including coughing, wheezing, shortness of breath, and sneezing. You might also experience symptoms that resemble allergies, such as itchy eyes and sinus infections. Other telltale signs include skin irritations, persistent and unexplainable headaches, and mental confusion, often described as 'brain fog.' It's important to remember that mold can cause health problems even if it's not visible, as it can grow inside walls. If you are experiencing these unexplained symptoms, you may want to consider a professional mold inspection.

Some of the signs that could mean your water is contaminated, such as cloudiness or bubbliness, could also be non-problems that don’t affect your water’s potability. However, if your water smells or tastes strange, it’s a good idea to stop drinking it and test it immediately. If your well water is contaminated, the best way to discover that is to test it.
