Air Quality Testing

Winter is around the corner and as we face a few months where most of the time windows are closed, the air in our homes can contribute to illness. The following information can be found on the Lung Associations website:


Your home should be safe and comforting, not a place that makes you sick. People can have air quality problems in any kind of home, new or old. The good news is that you can do something right now to improve your home's air quality.

Testing for indoor air contaminants is possible, though not usually necessary. For example, if you see visible mould, it needs to be cleaned up. You then need to correct the problem (leaky pipe, excess moisture, etc.) that caused the mould to grow in the first place. If you notice a musty or mouldy odour in your home, trace it to its source and deal with the problem there. You should remove obvious sources of contaminants as soon as possible, unless "before and after" documentation is required for medical and legal reasons. Testing can then be performed, if necessary, to pinpoint any residual contaminants that may be contributing to ongoing health problems. If you or others in the home are experiencing symptoms which you feel are caused by something inside your home, check out The Lung Association's Healthy Home Audit (PDF) or visit, a website that takes you on a tour of a typical house and points out air quality trouble spots.

If you still can't find the sources of your symptoms, you may next want to consider air sampling by a qualified professional. Canada Mortgage and Housing Corporation (CMHC) has a list of trained Indoor Air Investigators; call CMHC at 1-800-668- 2642 to see if there is an investigator in your area. Or, check the yellow pages in your phone directory under 'Environmental Consultants' to see if indoor air quality services are available. Ask about the consultant's training. Inquire what they base their analysis on and if you will be provided with a written report. Ask for references and contact the Better Business Bureau.
