Think you have mold in your home? You are right. Every home has some type of mold. Mold gets in your home through air movement from open windows and doors, pets moving in and out of the home, building materials left exposed while the property is being built. Once mold has entered the home it may be dormant for long periods of time until moisture has been added and allows the mold to breed. The Glenview home inspection looked really nice to the naked eye. Unfortunately, after we performed a mold air test the test revealed that in fact there was a high count of mold that was in the property. There was no visual mold seen that would lead me to believe that there was a mold issues in the home. Mold grows in many places and all it needs to grow is a food source, moisture and warm temperatures.
Some of the best places to find mold are below.
- Crawlspaces are notorious areas to find mold. The crawlspaces can be dirt, concrete or gravel and will still have the opportunity to be a breeding ground for mold. If the crawlspace is heated and the walls are not insulated the mold can breed on the dust perticles on the concrete walls or the wood floor joists. You would never notice that there was a mold issues because you probably never enter the crawlspace.
- Attics are known areas for mold to grow because bathroom fans are known to be vented into the attic. These fans deliver moist air from the living portions of the home. The air that is being delivered into the attic from the bathroom is generally from shower steam and has a Relative Humidity 75% – 80% and will cause mold to breed on the sheathing in the attic. Poor circulation in an attic also causes the air to have high RH values and in turn possible mold issues.
- Duct work in attics that don’t have insulation on it causes condensation on the exterior of the duct that may drip onto attic insulation or attic framing and allow mold to breed.
- Bathroom fixtures are notorious to have mold growing on them. Tubs and their surrounds are known to have mold on them.
- Basement window sills are known to be breeding ground to mold because the cold or hot air can enter the window and mix with the interior air and allow the moisture to come out of the air and condensate on the walls and sills of the windows.
These places are areas that I searched for water intrusion, air leaks and mold colonies at the Glenview home inspection. We did perform a mold test at the Glenview home inspectuion which did come up positive for several types of mold spores. None of these types of mold spores were to a level that would cause concern.
Thank you for stopping by and stay safe.
