"Your crew was exceptional! Very neat, professional and competent."
Testimonial by Kevin H from Bradford, MA

"In all the years I've owned homes, I've never had water in my basement so my first flood was very unsettling. Your whole staff was more than accommodating to my needs. I feel like you bent over backwards for me which I'll always remember."

Crawl Space Fan

What It Does:

Venting a crawl space with outside air brings summer humidity and cold winter air into your home, which leads to damaging mold and rot underneath your home.

The Crawl-O-Sphere Crawl Space Fan provides another way to ventilate a crawl space environment-- with the already-conditioned air present in your home. The Crawl-O-Sphere is for use only in homes with central air conditioning.

The Crawl-O-Sphere is intended as part of our crawl space vapor barrier system. When combined with our crawl space moisture barrier and vent covers, it provides a cost-effective way to keep a crawl space dry.

Installation Time:

Mounting a Crawl-O-Sphere in between the floor joists and installing a vent to the floor above will be done within the specified time frame for the rest of the job.

Properly Ventilating A Crawl Space

There are many products on the market these days that are used to ventilate crawl spaces. Some suggest taking air inside your crawl space and blowing it out of the house. Others recommend blowing air from the outside into your home. But what if it's damp, humid, or cold outside?

At Basement Systems of New Hampshire, we recommend installing a crawl space dehumidifier over using a crawl space fan. However, if you're looking for a more economical way to dry your space, the Crawl-O-Sphere is the way to go.

Since an encapsulated crawl space becomes part of your housing envelope, you can dry it without significant changes in your home's energy efficiency. Depending on the size of your crawl space, this system will typically draw between 15 and 80 cubic feet of air per minute from the home above.
