“What Do You Mean Allergies Aren’t Normal?”


If you have an allergy flare-up once a year (or more), something’s wrong

The following info may raise an eyebrow. (Or relieve a nostril!) Do you ever:


If “yes” or if you get seasonal allergies, this is not normal. It is quite likely caused by unhealthy indoor air. According to the American College of Allergy, Asthma and Immunology:

Over 50% of all allergies are related to poor indoor air quality.

This includes air that’s too wet or dry (questions 1 and 2) plus air that has dust mites, pollen, molds, pet dander, insect debris, smoke particulates and “off gassing” of chemicals in your home which could be polluting your lungs. In short, your air can be making you sick.

Living in Contra Costa County, we hear complaints every year about illness, missed work, “passing around a cold,” that we KNOW we can help control. That’s why we want to test 50 “sample” homes with a completely free, no-obligation Duct System Review. There are no strings, no catches; STEWART is just trying to improve quality of life through research.

We’ll review your entire air delivery system. Plus, we’ll also electronically test for Carbon Monoxide (CO) to try and spot this odorless, colorless killer.

The results are yours, free. If we find contamination, you make the decision on what to do. No pressure. If we don’t find contamination, then you get great peace of mind. Again, for free.  Please keep in mind:


The call, appointment and test are free. Plus, our work is 100% guaranteed, no matter what we find. Just fill out this form online, email us at or give us a call at 925-203-9141 today.
