Rochester Homes delivers its home product across a diverse area throughout the Midwest where the terrain and soil can vary greatly. Homes built by Rochester cannot go on a concrete slab but must be placed on either a crawlspace or basement foundation. Basements completed by the builder make up most of the homes built by Rochester, but in some cases where there are higher water tables, a crawlspace may be appropriate.


There are two types of crawlspaces: vented and conditioned. Vented crawl spaces are commonplace and generally comply with local and state building codes. These types of crawlspaces are vented to allow air to pass through. As a result, vented crawlspaces are ineffective at staying dry.
Related to basements, conditioned crawlspaces are protected enclosures. Vented crawlspaces usually are exposed to raw earth, whereas in conditioned crawlspaces they are seamed and taped with a 10-mil vapor barrier used to cover the ground to suppress moisture. Insulated polystyrene foam panels are installed and affixed along the inside perimeter walls. Supply and return air registers are located at opposite ends of the crawlspace to maintain proper climatic conditions.


Conditioned crawlspaces are preferred most importantly to control humidity. Humidity causes moisture in-turn can mitigate to mold if not addressed. It is better to prevent the problem than to fix it. This can affect indoor air quality in a home’s living space as well as lead to further deterioration of your property.


A sealed, conditioned crawlspace can reduce noise and lower utility bills, as well as prevent unwanted pests from taking up residence there.
