Rely on the Building Science Experts

Nobody understands the science of building better than . If you want to create a thermally efficient and air tight space, it's not enough just to insulate. You must choose the right insulation and air sealing system for the application, and be sure it's properly installed.

LET.     US.     HELP.

Crawl Spaces & Basement Insulation and Remediation

There may not be an area of the home that creates a bigger hazzard to the occupants health than that of a typical crawlspaces.

Most homes with crawlspaces are not properly insulated for moisture control and this can pose health concerns for the occupants, especially children.

Lack of properly sealed and insulated crawlspace can allow dealdy and odorless gases to affect occupants. It can also become breeding ground for insects, rodents and mold. In addition, it could cause damage to the foundation and the floor system.

The Stack Effect

The Stack EffectGraphic showing where air will infiltrate a home even if you have proper window and door sealing.

Crawl spaces are often damp, humid spaces due to water runoff from rain, irrigation systems or an elevated water table. While the building code requires crawl space ventilation, this ventilation does virtually nothing to mitigate moisture problems and can actually make moisture problems worse.

Houses operate like chimneys.

If you introduce a hole at the bottom of a chimney, a natural draft ensues as air exits the top of the chimney.

This is called stack effect.

Attic ventilation is the top of the chimney and crawl space ventilation is the bottom.

As air is drawn up through your house, moisture, mold spores, odors and soil gases from the crawl space find their way into the living space.

The Solution

Crawl space encapsulation involves sealing the under side of the floor with a Closed Cell Polyurethane spray foam appliation and covering the ground using a tough 15-20 mil, reinforced polyethylene sheeting (not some thin 6 mil poly) taped carefully at the seams and adhered to the top or bottom of the concrete foundation wall.

Sealing up all ventilation entering the crawl space is a specification 'if' it is decided that ventilation is not neccessary for mechanicals. Sealed below this sheeting are soil gases, moisture, water vapor and odors that typically would be drawn up into the living space above.

The Solution

We are very proud of our projects because our specs are superior and our prices even better! We do not pay any enormous franchise or licensing fees to national companies and therefore, we are able top design a system that fits your home and your budget.

If you want to build a thermally efficient and air tight home, it's not enough just to insulate. You must choose the right insulation and air sealing system for the application, and be sure it's properly installed.

Did you know that an improperly insulated and sealed home delivers 4500 lbs. of excess greenhouse gases into the air each year? It can also waste 20 percent or more of the energy used to heat and cool the home.

Our Building Science experts understand the principles of heat, air and moisture flow, and how the building envelope interacts with a building's mechanical systems as well as its occupants.

N.A.S.A. applied one-inch of spray-on foam insulation on the Space Shuttle's External Tank that serves to insulate the tank. The closed-cell foam used on the tank was developed to keep the Shuttle's liquid hydrogen fuel at minus 423 degrees Fahrenheit and the liquid oxygen tank at near minus 297 degrees Fahrenheit even as the tank sits under the hot Florida sun while preventing a buildup of ice on the outside of the tank.

Properly insulating and sealing your homes with Spray Foam is a greener alternative. .

TAP to expand the Better Building Performance - Theory vs. Practice section

It is now well established and accepted by most architects and builders that controlling air infiltration is the best and most cost-effective means of reducing wasteful heat loss and providing a comfortable indoor environment.

Most architects tend to design structures that are tight and energy efficient by incorporating the latest in proven, energy saving construction details into their drawings.

Unfortunately, too many buildings still perform poorly. Why is this?

We have found that since there is no performance specification to dictate building construction, there is no guarantee when it comes to building performance. Regardless of the contractor's ability, tight buildings are not created from a list of materials and drawings in the absence of specifications that dictate the building's designed environmental performance.

takes a different approach

To improve building performance, our company focuses on the basic building science principle that air infiltration compromises the effectiveness of the building envelope. Our approach is incremental - areas of infiltration are diagnosed and fixed in order of magnitude. This provides the most thorough and cost-effective solution possible.

has satisfied clients. Our clients have been extremely pleased as they benefit from cost-savings and an immediate improvement in comfort.

We operate two-part urethane injection equipment to superinsulate new and old buildings. Included in this equipment are special nozzles and guns to seal cracks and small openings which effectively stops infiltration that cause poor thermal performance.

There are other urethane contractors who provide typical spray foam services; however, very few go beyond the installation of conventional spray-roofing and spray-wall insulation processes.

Our capabilities, while serving these common markets in some cases, are specially designed to meet the unconventional needs of specialty markets.

By employing standard and custom equipment which processes foam through both spray and injection techniques, we can utilize numerous chemical systems with varying densities, speeds, closed-cell content, fire rating, vapor permeability, and other desirable environmental characteristics.

While there may be other foam contractors who provide spray and injection services, to the best of our knowledge, we are the only company that currently uses "ratio monitoring" equipment in the field for this process. Ratio monitoring enables our technicians to maintain the exact chemical formulation (mix) for the duration of the installation process.

It is impossible to guarantee that the appropriate mix is being maintained without the use of this equipment.


  • Fans, Ducts, And Controls - We install bath fans, attic/gable fans and crawl fans w/ humidistat/thermostat controls. Ductwork for bath fans and kitchen hoods, with roof jacks/caps. Helping to get out any of the kinks in your ventilation.
  • Cleaning and Pest Control - We clean out crawl spaces. Sanitize from rodent pheromones, perform exclusion work to block rodent entry, build new access hatches etc.
  • Draining Issues - We can help with drainage and water mitigation issues. Sump pumps in crawls/basements, along with french drains in and out of crawls.
