What Does an Indoor Air Quality Study Cost?

To request a proposal or cost estimate, please contact us by phone or email and give as much detail as possible.  We will likely want to call back emails so that by gathering some important additional information we can make a cost estimate as accurate as possible as a phone call is the preferred method for developing a sampling plan.  We will plan on how many samples we expect to collect in order to make important decisions such as occupancy determination, and if necessary decontamination and/or remediation.

​The cost of a project is based upon the time involvement required to come onsite and conduct the sampling and investigation, generate a report with the level of detail required for the client situation, and the type and number of samples or monitoring equipment needed to evaluate the air quality, or surface samples to determine presence of mold or tother contaminants. 

Be assured we do not try to low ball you to trick you into contracting our company like many other companies do when they fail to mention there is a cost for a written report.  So by the time they add everything on the final tally, it is frequently more expensive than Clean Air Sciences, Inc. and provides significantly less content.  Where others provide a 1 to 3 page report and 10 to 15 pages of lab data and statistics, we generate reports that are anywhere from 5 to 20 pages plus the lab data.  Don't be fooled, you get what you pay for and you can't get much for $400 to $500 promised by other companies.

In general, the cost of indoor air quality projects are as follows: 

​Residential Indoor Air Quality/Mold Investigation/Inspection: $700 to $1,200+

Residential Real Estate Transaction Mold Inspection: $600 to $1,100+

Commercial Indoor Air Quality/Mold Investigation/Inspection:  $900 to $2,000+

Commercial Industrial Hygiene or OSHA Compliance Study:  $1,000 to $5,000+


Conflict of Interest?

Clean Air Sciences, Inc. does not sell any products and we don't recommend any specific brands if asked by clients about furnace filters, air purifiers, or dehumidifiers.  We also do not perform any mold remediation, decontamination, or cleaning services. 

We are strictly scientists/consultants and perform inital investigations to set the scope of work and protocol for remediation.  We also perform Post-Remediation Assessment QA/QC sampling and inspection to ensure remediation contractors fulfilled the requirements of the remediation plan and no mold growth or other sampled contamination remains.  We do not give any preferential treatment to remediation companies we have worked with or who have refered us to the client.  If their work is not satisfactory and sample results warrant it, they will fail Post-Remediation Assessment.

​For litigation projects we will conduct a conflict of interest (COI) search of our client database to ensure none exist between a potential client and a former client.
