"Steve, the owner of the company was extremely attentive to our problem. We were concerned about an odor in the house that smelled like mold. Steve came over the same day we called to test our air to be sure that we were not living in a dangerous situation. He sent air samples that he harvested in numerous places in our home and crawlspace to an outside lab for testing. A few days later he called us to let us know that there was some mold but it was not the dangerous kind. He followed up the phone call with an official report from the lab. The primary souce of the mold was the crawlspace. Steve cleaned up the source of the mold and helped us find the source of water that was causing the problem. He is in the process of cleaning out the crawlspace of debris that was harboring the mold at this time. The odor is now gone and we are so relieved."

We utilize only the most reliable and proven scientific methods in order to obtain accurate honest information you can trust.

Not us, we only do testing so there is never any conflicts-of-interest. When you hire Air Basics, you will get answers to questions such as: Do we have a health hazard? How bad is it? Where is it coming from, what's the cause? What will it take to fix it? What parts of the home are not affected? How long has it been here? We're on your side and want what's best for your family and your wallet. Hire a true expert for the same cost. Our prices are competitive with companies who utilize "low-skilled technicians". Other indoor health issues we commonly handle include: Mold, asbestos, lead, pesticide residues, bacteria from sewer back-ups, radon gas, wildfire smoke and soot, water quality problems, allergens from pets, bat or rodent infestations, identifying mysterious odors, formaldehyde, odors from new furniture, and identifying exposures that could be contributing to difficult chronic health problems like chronic fatigue syndrome, multi-chemical sensitivity, auto-immune disorders, COPD, allergies and asthma. Our team also includes experts on the various environmental laws and regulations that impact the construction industry in California and Nevada, and we offer our professional regulatory compliance services to property owners, lenders and construction firms.

"Ezra and Charles are very friendly and personable. That is, when they want to take your money. What good is a 12-year warranty if you start ignoring your customers at 2 years. I needed my HVAC replaced. Because the HVAC sits on my roof, I decided to redo the roof too. Ezra and Charles came out and were really friendly so I immediately had a good impression of them. Even though it would’ve been cheaper to go with a roofer and a separate HVAC company, I decided to go with Landmark Construction Crew, aka Landmark Energy Upgrades. I figured it would be a more seamless process for one company to do both. I got this done in December of 2016. The thing with a roof is that you don’t know if it’s a good job or not until it rains so I waited to write a review. Around January 2018 ( a little over a year later ) we got some much needed rain but unfortunately, I had a leak coming from one of my vents. I emailed Ezra and he sent out a roofer. The roofer came, looked at the vent, jumped up on the roof for ten minutes and said he was done. Months later, it rained again, it leaked again, I emailed Ezra again. I decided to take a closer look at the vent and noticed that there was sunlight in the ductwork. I figured sunlight equals gap somewhere. When the roofer came, I told him and he said it’s nothing, probably just a reflection, without even taking a look. Then the roofer tells me that the next time there is a leak, I need to call the HVAC guy because it’s not a roof problem. I couldn’t believe it so I told him that HIS company IS the HVAC guy!! I used one company to do the roof and the HVAC so there is NOBODY else to blame. So, he jumps back on the roof and was done and gone in 10 minutes. About a month goes by and the rain is back and so is my leak. It’s 2019 so it rained a lot this year. Good for California, bad for me. So, I emailed Ezra again. After a few weeks, no reply. So, I email him again with pictures, a few more weeks go by and no reply. So, I call him and he picked up the phone. He sounded surprised to hear from me (probably didn’t recognize my phone number) and I start telling him about the leak. He said he didn’t get my emails but just text him my address and he’ll send somebody. A couple of weeks goes by and nothing. So, I text him again and after weeks and weeks of waiting, no reply. I’ve emailed, called, and texted so, at this point, it’s very obvious he’s avoiding me. If you are looking for a friendly company that is willing to take your hard-earned cash then Landmark is for you. But if you’re looking for a company that is accountable for their work then look elsewhere. I know I am."
