Bought A New House? Test Air Quality Before You Move.

Bought A New Home? Test The Air Quality Before Y

So you just bought a new house or a resale house in the Toronto area or GTHA. Congratulations first of all! Hopefully, you were able to get a reasonable sale price and you were also allowed to have a structural home inspection to ensure there are no surprises coming your way from a structural or mechanical perspective. What about the indoor air that you and your family will be breathing? The indoor air quality of a new residence is often overlooked or clients believe that the structural home inspection covers this…it doesn’t.

The home (even brand new ones) could have had some water damage in the past, could have had mould cleaned up, could have chemical off-gassing issues, could have inadequate ventilation, poor air purification and the list goes on.

In a resale home, the previous occupants could have had a rodent or mouse issue, could have had pets and if you are allergic to pet dander, rodent allergens or dust mites, this could cause annoying and in some cases serious health issues for sensitive individuals.


Top 10 Indoor Air Quality Allergens In A Home:

  1. Airborne Fine Dust
  2. Poor Ventilation
  3. Airborne Mould Spores
  4. Formaldehyde
  5. TVOC’s
  6. Airborne Pet Dander
  7. Airborne Rodent Allergens
  8. Airborne Dust Mite Allergen
  9. Pollen issues
  10. Bacterial issues (E.coli).

The first 5 of the above top indoor air quality issues apply to homes that are just built and brand new as well as resale homes in any community, not just the Toronto and surrounding area. Even brand new homes would have been open to the elements at some point and can have hidden mould growth in attics, near bathrooms as well as near windows and doors.

In most resale homes, finished basements can hide quite an array of problems. HVAC systems in both new and old homes seem to be poorly installed, undersized or may be contributing to the home’s indoor air quality problems and poor indoor environmental conditions.

When buying a home, it is important to look for some telltale signs of a potential problem. Should any of the following issues be found, then a professional indoor air quality assessment or air quality test is highly recommended.

  • Swelling or water damage in the basement on baseboards or door jams. This can indicate a past flood and hidden mould growth.
  • Water damage in corners on wall surfaces. This also can indicate a flood or foundation issue.
  • Visible mould growth…for obvious reasons.
  • Excessive accumulated dust. This can indicate a lack of cleaning as well as possible poor air purification systems.
  • Condensation or mould on window frames. This can indicate a ventilation issue leading to elevated RH% or humidity leading to allergies and mould.
  • Mould in the attic on the underside of the roof system. This could mean that bathrooms vent into the attic. This can lead to a mould issue in the attic, rarely inside the home.
  • Furnace filters that don’t properly and fully fit the casing they are in. This can lead to airborne fine dust and allergen issues.
  • Past evidence of rodent damage or odours.
  • Past evidence of pets for allergy sufferers could be an issue.

The best way to make sure that the home you just bought has good indoor air quality is to call us and book a professional air quality test. We can show you what is in the air that you are breathing and if it needs anything to improve the indoor air quality.

There could be several reasons for turning down the furnace or heat in your home during the day, especially if no one is going to be home.

However, with these good intentions you may actually be harming your indoor environment and causing poor indoor air quality with fluctuating temperatures. Here is a list of problems associated with turning down the furnace for a few hours or even a few days when no one is home. Top 5 Reasons not to turn down the Heat when you leave the house: If it gets too cold, plumbing pipes could freeze

Your Home Should Be An Air Quality Safe Haven

Outdoor air pollution in Toronto and Southern Ontario is very poor today due to the Northern Ontario forest fires. We had a lot of pollution this spring with higher than normal pollen counts leading to more serious allergic reactions. Now, asthma sufferers are having to deal with the high dust counts outdoors from the soot and smoke from forest fires. This is Climate Change folks and it’s here to stay. This is why your home should be an air quality safe-haven! How? It’s actually easier than you think. To control outdoor pollutants such as seasonal pollen, ragweed, and grasses as well as summer soot and smoke particles from forest fires as well as other outdoor issues such as exhaust from cars and industry…you need proper ventilation and filtration. Proper ventilation will help dilute, dissipate and exhaust indoor air quality pollutants such as Carbon Dioxide (from us breathing), chemical issues such as VOC’s (from building materials and contents), and control indoor humidity that could

What Do I Do If My Basement Is Wet?

  With all the recent rain in the Toronto and GTHA area recently we are getting lots of calls from people concerned about damp basements and recent water or moisture issues. Most callers want to know how they should dry out their homes and prevent mold. Here are some general tips on mold prevention. One of the first things that you should do is STOP and THINK. Don’t do anything in a panic. Many people when faced with moisture or mold panic and in many cases make the situation worse.   You should first determine if this is the first time the area got wet or if this has been a recurring issue. The reason for this is that if there is a potential that mould has grown in the past in the affected area and may still be there….or if you see mold…it is best to call a professional mold inspection or professional mould remediation company. Mold clean up is not a DIY project and can have serious and costly results if you don’t have the right equipment and don’t know what you are doing. You can mak
