For most of us, our homes are our biggest investment and damage and/or required repair to our home will have a big impact on its value. When a dryer vent system is broken, warm moist air produced from the dryer is exhausting somewhere inside the building. Most commonly it is vented into a wall or floor cavity, attic or crawlspace. The warm moist air will then condensate in these areas which can be a source for mold or dry rot damage.
Mold remediation and dry rot to a structure is significant and very costly. When you have your dryer vents cleaned we strongly recommend arranging interior access so that the technician can verify the vent is intact and airflow is terminating at the correct location. If it is determined a repair is needed invest the couple hundred and save yourself a lot of money down the road. Based on quick analysis of our 4th quarter 2017 data, the average cost to repair a broken dryer vent was $234. This is relatively inexpensive considering the cost of damage to your home if mold, dry rot or other damage is caused.
