Crawlspace Waterproofing – Should I Insulate My Crawl Space? – Stamford, CT

When considering crawlspace waterproofing, many homeowners are faced with the question of whether they should insulate their crawl space or not.

A good reason to consider insulation

Many people underestimate the role their crawl space plays in determining the conditions in their home. If your crawl space is dirty and moldy, your home’s air will be contaminated. This is one of the main reasons crawlspace waterproofing is so important.

When it comes to the question of insulating the space, you should stop and think about your crawl space as a mini basement. Would you leave your basement without insulation? If you did, you would be losing a lot of heat from the home through the basement. You should be prepared for very high energy bills.

The crawl space is the same. Crawlspace waterproofing helps to conserve energy by creating a barrier through which air cannot freely circulate in an out of the crawl space. Encapsulating your crawl space therefore helps to reduce the amount of heat lost from the home through the crawl space.

However, encapsulation’s contribution to the energy efficiency of your home is limited. If you truly want to make a difference, insulate your crawl space during the waterproofing process.

What about moisture in the crawl space?

One of the main concerns homeowners have when they consider insulating their crawl space is the buildup of moisture in the material used to insulate the space. However, moisture shouldn’t be an issue if the insulation is done right. The following steps should be taken for the best results:

  1. The ground in the crawl space should be covered.

This will prevent moisture from rising into the crawl space from the soil. The area can be covered with a vapor barrier that keeps out soil gases as well.

  1. Insulation should be placed under the floor

Insulation should only be placed under the floor of the house. Insulating between the floor joists of the crawl space will help to prevent heat from escaping from the house above into the crawl space below.

  1. Encapsulate the foundation

Encapsulation contributes to the energy efficiency of the home by preventing the circulation of air into and out of the crawl space. It also prevents moisture from entering the crawl space.

Discuss the possibility of having your crawl space insulated with your waterproofing contractor. They will advise you on the best solution for energy efficiency.
