Even if you have effectively dealt with water entering your home, you still might notice high levels of humidity, typically in the summer months, in your basement and perhaps throughout your home. We have addressed this issue before (https://www.thebreathablehome.com/blog/watch-your-humidity-levels), but have a few additional comments to make.

Natural air exchange is typically enough to regulate humidity in your home to acceptable levels. But, as companies such as ours work weatherizing, or tightening your home, we might affect the ability for moisture to wash out, which could result in the rise of indoor humidity.

As we work on tightening your home to the outside elements, we monitor our progress with a periodic blower door test. This test tells us if we have reached the lower limits of effective air exchange, at which point we would want to consider adding mechanical ventilation. There are several options, including a balanced Heat Recovery Ventilation (HRV) system or Energy Recovery Ventilation (ERV) system. We typically know when quoting the job if this will be needed, so this is not an added expense to the project as it progresses.

Another option we go to often is the installation of an efficient bath fan that is set on a timer that allows it automatically turn on and off throughout the day. This allows us, and you, to achieve proper air exchange at far less cost than installing an HRV or ERV.

If air exchange doesn't effectively control humidity levels, installing a portable or permanent dehumidifier would be the soloution. And, a great side benefit of a heat pump is that when it is in air conditioner mode, is it removes excess moisture from the indoor air.

If you're unsure of your indoor humidity levels, we strongly recommend placing a couple humidity meters, or hygrometers, throughout your home. Feel free to report your levels back to us and we can let you know if there should be a concern.

Communication with a commitment to customer satisfaction set Bo and his crew apart from the rest. As I sought contractor quotes for insulation I was shocked by those that never returned a call, EVER, or those who wanted to quote my work over the phone. Bo returned my call within a couple hours and set up an appointment to come and examine my project. My early indication that this company was different from the rest: The appointment was for 9:30am and Bo called at 9:10am to say his GPS was indicating he would not be there until 9:37am and he wanted to confirm he was on the way but would be a bit late. Bo took about an hour to look over my project, examine the construction, ask about the intended use, heat source and informed and educated me about several insulation options.
