"This was not the first time using an Air Quality inspection company. They were help full, accessible, timely, accurate, and provided an analysis report that included a representative to review and answer questions. They also provided a referral to a remediation company that approached the issue in an efficient and cost effective manner."

"The home inspector had completed the report for previous buyers that backed out. We hired him to recheck the property to see if issues were repaired as the homeowners told us they did repair most things on his report. Victor was very thorough in his report and the walk through. He had the report ready 10 minutes after the walkthrough. With his report we will be able to go back to the sellers and ask for a few more repairs. He also gave us a new home owner guide which has a lot of useful information for this older home that we can use a reference. I will use victor again in the future for mold inspections or home inspections!"

"Luke, the owner is amazing! Very honest, knowledgeable, professional and proficient! My family had to ic mold so bad in our home for a very long time. We were all getting sick, I was the worst that the mold was attacking. We did not know why we were getting sick except for the reason perhaps the weather this year and the allergies. We started seeing the mold coming out in our bathrooms and up on the ceilings. That was an indicator we might be getting sick from the mold. A family friend of ours found this amazing company and I reached out. Luke, was so knowledgeable when I spoke with him on the phone. He came out to our home and ran 2 air tests and a swab test!!! He emailed us the results and called me to explain the results and let us know how BAD it really was!! It turned out it was not just the mold that was visible but the mold that we could not see and that we were breathing!! We then hired him to come and treat the mold!! I can honestly say that the mold is gone!! We have no more fear of living in our home and breathing toxic mold!! We are all feeling much better now! No more horrible coughs, running noses, headaches, fatigue feeling!!! I can not speak highly enough of this company!!! I recommend this company to anyone who knows they have mold or is in doubt and curious to have an inspection or run some tests in their home to be proactive! They did such a thorough job from testing, to treating and cleaning out home!!!"

"We had several issues that caused us to contact a company that can come over and check our house for any problem that can be solved and reduced our utilities bills. We contact this company and we asked them to come over and see what they can do. Avi came over and explained to us how they work and what they do in order to determine what can be done. The initial work included sealing all the openings in the house and then they made some tests with special machine that made a clear picture that our air conditioning system have some leaks that causing the system to work extra time. After they completed the testing, Avi came over with another crew of workers and fixed the ducts making sure that there will be no more leaks from that area. The work that they did was good because they made a massive testing before they came to the conclusion about the air conditioning ducts.

"Excellent! Daniel was very professional and reasonably priced. He was prompt, friendly and willing to work and I’d definitely hire him again and totally recommend him and his services to anyone that might be in need. He got the job done in my short time frame too, as I was moving and it was kind of an emergency."

Mold Testing and Remediation FAQs, answered by experts

Vermiculite insulation that comes from a particular mine before 1990 is likely to contain asbestos. This is particularly true in the U.S. However, not all types of vermiculite insulation contain asbestos. Since you can't detect the presence of asbestos without special equipment, it's best to assume that the insulation contains the dangerous mineral and to either leave it alone or hire a professional to handle it.

According to the Environmental Protection Agency (EPA), hazardous waste is generally classified into four main categories:

1. Characteristic Wastes: These exhibit at least one of four hazardous traits: ignitability (flammable, like gasoline), corrosivity (can rust or decompose materials, like car batteries), reactivity (unstable and can explode, like aerosol cans), or toxicity (harmful when ingested, like lead-based paint).

2. Listed Wastes: These are specific wastes from manufacturing and industrial processes that the EPA has officially designated as hazardous. They include byproducts from processes that use solvents, pesticides, and other chemicals.

3. Universal Wastes: These are commonly generated hazardous items that are subject to streamlined regulations. Examples include batteries, pesticides, mercury-containing equipment (e.g., bulbs), and some lamps.

4. Mixed Wastes: This category includes waste that contains both hazardous and radioactive components, making it subject to regulation by both the EPA and the Nuclear Regulatory Commission.

Black discoloration on your attic insulation may be caused by buildup from soot, dust, or dirt, which does not come with dampness or a musty odor. However, another cause of black discoloration on attic insulation is black mold, which has a musty smell and other signs of damage. If you’re unsure what black stuff you’re looking at, consult a pro to be safe.

One of the first signs of mold in an air conditioner is a musty smell. You're likely to notice the smell when the unit runs, from the air coming out of the vents or the unit itself. You may also be able to see mold growing on the unit, such as near the condenser coils or by the fan. In some cases, there may be visible mold by the vents.

Sewer gas in any location can cause eye and respiratory irritation if you’re exposed at low levels, or more severe symptoms if you’re exposed at high levels—but fortunately, the fresh air outside means it’s less likely to affect your physical health. However, sewer smells outside can still indicate significant plumbing problems that will need to be dealt with, such as a potentially damaged sewer line or roof vent pipe.
