"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!!!"

"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

A professional indoor air quality inspection takes anywhere from one to three hours, depending on the size of your home and the number of necessary samples. After the test, the specialist will discuss the findings, but you won’t get a full written report for 2 to 10 days, though you can ask your pro to expedite the process, if needed. 

In some cases, yes, insulating an unheated garage can lead to mold and mildew. The issue with insulating a garage is that the interior will warm up and cool down more slowly than the exterior air, which can cause condensation inside the space. Where there is moisture, there is likely to be mold and mildew over time. Installing a vapor barrier can help avoid moisture and mildew problems in an insulated garage.

While bathroom mold, commonly known as black mold, does not produce harmful mycotoxins, it can still pose health risks. If disturbed, mold spores can become airborne and potentially cause allergic reactions, respiratory problems, skin irritations, and other health issues. This is especially true for individuals with allergies or sensitivities. While bathroom molds are not as dangerous as other mold species, prompt action is crucial to mitigate health risks and prevent further spread. 

Asbestos is absolutely cancerous. In fact, around 4% of all lung cancer cases are the result of asbestos exposure. This is why we recommend a full, professional removal and cleaning of any asbestos found in your home. If you are unsure whether there is any present, you should call a pro who will inspect your property.

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.
