Crawlspace Foundations
Beside the extra cost to construct, crawlspaces should be insulated. Insulating options are varied and discussed on another page.
Wood subfloors that come with the crawlspace can become squeaky if not properly secured.
Squeaky floors can generally be avoided, however, with a few measures described later.
Heating and cooling is generally more efficient when the vents are located in the floor. Crawlspaces make that easy as opposed to a slab.
Plumbing and ductwork are more easily accessed in crawlspace house.
The concrete slab foundation versus the crawlspace is one of those situations in which there is no single right answer for everyone.
The plusses and minuses of each speak for themselves, and most often the choice comes down to individual preference.
The “spec” houses that I have built for sale on the open market, have been primarily slab foundations, simply because of the cost savings.
Crawlspaces provide easy access to plumbing, electrical, and heat and air ductwork.
