"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

If you would like the insurance company to potentially help you pay for the mold remediation, you need to inform the insurer. When you notify your insurance company, they may say that you need a mold inspection before receiving any money for mold remediation. It’s possible that the insurer would not pay for this inspection unless they find mold.

Yes, outside leaks can easily cause damage to your home if you don’t have waterproofing measures in place. Regularly check your property for signs of a leak, ensure your home’s landscaping is at least at a 5% slope, your basement windows are sealed, and you have an aligned gutter system to catch rainwater.

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.

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.

Soaking memory foam can break down its structure over time or even encourage mold growth. However, brief encounters with moisture will not ruin your memory foam. As long as the mattress, topper, or cushion dries soon after getting wet, there's nothing to worry about. Just be sure to keep the affected item in an area with plenty of air and sun to encourage quick drying.
