Conditioned Crawlspace

In the early 1950s crawl space foundation vents were introduced to eliminate humidity in crawlspaces. Over time contractors and inspectors realized the vents that were installed to remove humidity in fact helped to increase the humidity level in most crawlspaces. They allow hot humid air in the summer months to enter the cool environment of a crawlspace. The humid air would condense and create higher humidity levels under your home.

Humidity Control

The theories behind the control of humidity in crawlspaces of buildings have changed over the years. It has been previously believed that the proper way to control humidity has been to utilize foundation vents to increase air flow within the crawlspace. The increase of air flow was designed to allow humidity to escape through the foundation vents to the outside of the building. Building codes required installing foundation vents according to the size of the crawlspace.

Control Mold Growth

Moisture, food, spores and warmth is required to sustain mold growth. If you eliminate any of these items mold will not be allowed to grow. The only practical item to control in crawlspaces is moisture. If you control all avenues of moisture you can help eliminate the potential for mold growth. A "Conditioned Crawlspace" is the preferred method to control humidity. Crawlspace Doctor has developed systems to control humidity with in crawlspaces.

Vapor Barriers

Moisture is evaporated naturally from the soil in crawlspaces. A proper vapor barrier is necessary to prevent the moisture from accumulating on the wooden structures of your home. The vapor barrier also needs to be installed on the exterior foundation walls of your crawlspace. This prevents wet foundation walls from emitting moisture into the crawlspace. Crawlspace Doctor has developed systems to install proper vapor barrier.

Drainage Systems

When all efforts have been made to prevent water from entering the crawl space a drainage system may be necessary to prevent water from accumulating. Simply installing a pump within the crawl space is usually not effective. All water entering the crawlspace needs to immediately be controlled before it can create excessive humidity. Crawlspace Doctor has developed systems to install proper drainage systems to prevent excessive humidity.

Insulation

When foundation vents were installed in crawlspaces they allowed cold air to enter. In the winter months the cold air had the potential of freezing water pipes and allowing the floors to remain cold. This challenged the heating system to try to warm the home. Fiberglass insulation had to be added to the floor joists in an attempt to prevent the cold crawl space air from making the floors cold. The same foundation vents that allow the cold air to enter in the winter also allowed humid air to enter in the summer.

Floor Supports

Floor supports can be added to help remove unstable floors. Spacing of floor joists, length of floor joists or deterioration of wooden members can all lead to unstable floors. Crawlspace Doctor can evaluate and determine all appropriate measures needed to improve stability of floors. Crawlspace Doctor can also evaluate the condition of existing piers.

Crawlspace Doors

It is very important for the health of your home to remove all debris in the crawlspace. Cellulose debris can be a food source for insects and mold. Debris can be harborage for insects and rodents. The debris can also injure people as they enter the crawl space to perform routine maintenance.

Waterproofing

Waterproofing a crawlspace as defined means preventing any ground water from passing through the foundation and accumulating in the crawlspace.
Most waterproofing techniques must be applied during the construction of the structure.
Outside perimeter drains, gutters, waterproofing materials on foundation walls and proper sloping of the land next to the structure all need to be considered.

Testimonials

This is a brief note of appreciation for your work on our crawlspace. Your work was excellent; we are very pleased with the results. We do not get any moisture inside the house and the crawl space itself is dry. The pump you installed there has done a wonderful job during the recent heavy rains, which caused problems for many people. It is great to have peace of mind, knowing that the crawl space is protected. We are also happy with your prompt response to any questions and special requests that we had. Keep up the good work. We can recommend your work to anyone without any reservations
