"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

Mold and mildew are the things in basements that actually cause the musty odors, but moisture is the underlying issue that causes mold and mildew growth. Addressing moisture and water problems and then removing materials that are moldy are some of the best ways to get rid of the musty odors. Preventive measures after that—like installing air fresheners and a dehumidifier—can help keep musty odors from returning.

Mold loves a moist environment, so the best way to keep it from returning is to keep your machine as dry as possible. Take laundry out of the machine as soon as you can after a cycle finishes. If your laundry room is humid, consider using a dehumidifier or at least running a fan to increase airflow.

It's also a good idea to leave the washing machine door open when it's not in use, to improve airflow and keep the interior dry.

Yes, if there is mold in your drywall mud and you then use it to build walls in your house—or if mold develops in your set drywall, like it can in hot and humid areas—it can lead to illness. Mold in your drywall (or other parts of your home) can make existing respiratory conditions or allergies worse, and the effect can be more intense for those who have existing health issues or compromised immune systems.

No, rubber mulch isn’t toxic and is considered safe to use around pets. However, pets, especially dogs, may try to chew on or eat rubber mulch, which can cause choking. Consider monitoring your pets and their behavior when around this mulch type to see how they respond to it.

The purpose of crawl space encapsulation is to prevent mold by blocking moisture and reducing humidity. If the vapor barrier is properly installed, it significantly reduces the chance of mold developing within the crawl space. However, mold can sometimes grow behind the encapsulation material, but it will be sealed away from the main area. Additionally, moisture can still condense inside the encapsulated space, so if you notice excess humidity, installing a dehumidifier is recommended to prevent mold and mildew growth.
