Increasing your attics insulation is typically the most simple and effective way to reduce energy consumption and improve energy efficiency for your home. Attic insulation is the key to creating an effective barrier against unwanted heat exchange; properly installed attic insulation can reduce energy consumption by 20% or more.

Improve the comfort of your home with our air sealing services
Sealing air leaks in your home is a simple, cost-effective way to lower heating and cooling costs, increase comfort, and create a healthier indoor environment. Heat can find its way out of the home through a wide variety of gaps, cracks, and holes in all parts of the house. With our blower door test and home energy audit, we can quantify how much air is leaking out of your house and pinpoint the leaks.
Common sources of air leakage
Air sealing targets common locations where air leaks occur in a house:
- Plumbing and wiring penetrations through floors, walls and ceilings
- Around chimney passes
- Attic access hatches, doors and drop-down stairs
- Around recessed lights and fans
- Around windows and exterior doors
- Cracks, gaps & holes in drywall or plaster
- Around electrical outlets and switches
- Sump pump holes
- Bath fans
- Leaky basement windows
- Rim joists in the basement or crawl space
Dense pack cellulose
Using dense packed cellulose for your wall insulation achieves two HUGE energy-efficiency-improving functions. First, it insulates your wall cavities, which dramatically reduces heat loss. Secondly, when cellulose insulation is dense-packed into your walls, it permanently tightens your home’s “air barrier.” This air-sealing technique drastically reduces air infiltration year round, further cutting energy loss. The overall impact of insulating your exterior walls with the dense pack cellulose is around a 20-30 % cut in your utility bills with non-insulated walls.
40% of the air you breathe in your home comes directly from the crawlspace. A crawlspace of 700 square feet can produce 10 gallons of moisture, rising into the floor system EVERY DAY. Number one cause of hardwood floors buckling is high humidity levels in crawlspace.
A vented crawlspace has foundation vents allowing air under your home. A vented crawlspace should have temperature and humidity similar to the outside environment. This means that a home that has a vented crawlspace should also have in addition to proper amounts of ventilation, a proper vapor barrier covering the earth as well as the subfloor being insulated.
The problem with vented crawlspaces is that the ground is rarely covered properly. This allows excessive humidity/moisture vapor in the area under the home. Over time the moisture can decay the foundation of the home if a proper vapor barrier is not in place. These moist crawlspaces can also cause insulation that you may have under your home to sag and become less effective. Other problems associated with vented crawlspaces include pest problems, mold/mildew, poor indoor air quality, and more.
We find that most crawlspaces are connected to the living space via holes, cracks, and gaps that allow crawlspace air and moisture to enter your home, introducing contaminants and decreasing air quality. Vented crawlspaces are the main source of high moisture levels in the home. In many cases, the home’s ductwork is located in the crawlspace.
Leaks in this ductwork can actually vacuum the crawlspace air up into the house every time the system turns on. Musty odors, sagging insulation, mold/mildew, and weak spots in the floors of your home are some of the more obvious signs of a crawlspace that may be in need of attention.
Not all vented crawlspaces are “bad” crawlspaces
- Vapor Barrier – A vapor barrier is a sheet of plastic that covers the ground under a home. Vapor barriers, if installed correctly, help resist moisture from the ground which would otherwise work away at the foundation of your home, as well as cause indoor air quality problems. A properly installed vapor barrier should consist of no less than 6 mil plastic over lapped, and taped at the seams, total ground coverage, and an additional 6-8 inches of plastic sealed to the foundation walls.
- Air Sealing – since 40% of the air you breathe inside your home comes from the crawlspace, it only makes sense to have your ducts and crawlspace sealed off from your living area. Air sealing a crawlspace consists of using an expanding foam solution to fill all cracks, penetrations, or other potential places where air can infiltrate your home from underneath.
