A blower door test is one way to determine if there is an overuse in energy due to air leakage. We will set up a large fan with a set of gauges in your doorway. The fan pulls out your home’s air and measures the amount leaking back in. During the test, we will locate the sources of the leaks and drafts. Next, we will seal off the house from the leaking air and monitor the results. This will leave your home more comfortable and energy efficient.
Important preparation steps:
Close all windows and open all interior doors
Turn down all thermostats
Cover ashes in wood stoves and fireplaces with damp newspaper
Shut fireplace dampers and doors, and wood stove air intakes.
What is Combustion Safety Testing? Combustion safety testing is a process of testing furnaces, boilers, gas dryers, ranges and other fossil fuel-burning appliances for the presence of dangerous carbon monoxide (CO), and for the safe function of their venting systems.
Properly burning gas and oil appliances should produce little to no CO. Excess CO may be caused by:
Misalignment of the burners
Broken components in the appliance
And other factors…
Air Sealing creates an important balance in your home.
The goal is to create a continuous thermal enclosure around the finished areas of your home. This stops the drafts and allows the insulation to do its job effectively.
One of the most important energy efficiency improvements you can make is sealing off the air leaks. Air leaking can account for 30% or more of your homes heating and cooling costs.
Not only will Air Sealing will improve your comfort level while reducing your utility bills, it will also help make your home more healthy and durable by preventing problems with indoor air quality and moisture. You may also notice less dust and pollen and fewer insects entering your home.
Insulation within exterior walls of your home can help to cut the amount of energy you use and your monthly costs for heating and cooling your home. Most people only think about attic insulation. Studies have shown that the average home can lose as much as 15% of interior heating and cooling due to air leaks and poor insulation within your exterior walls.
Exterior Wall Drilling:
The existing siding is removed and some holes are drilled. The walls will be packed with cellulose insulation. We will then plug the holes with a Styrofoam plug and reattached the existing siding.
Interior Wall Drilling:
There are times when exterior drilling is not possible. In the case, we will drill hole from the interior. After the insulation is blown into the wall we will patch the holes with foam plugs and spackling.
The attic is one of the easiest places to insulate in a home. Accessing the attic is much simpler than trying to add or replace insulation materials inside inner walls, floors and ceilings.
In most cases, blown-in insulation is used to improve insulation in the attics of existing homes. Attic insulation is generally blown-in over top of any existing insulation as a means of improving thermal management and increasing the overall R-value of the home. R-value is a measure of insulations resistance to heat flow. An R-38 is recommended.
If you currently use the attic for storage and would like to continue so after the insulation work you will first need to remove the storage temporary to give us plenty of room to work.
We can either blow underneath the flooring and dense pack the insulation into the rafter space (subject to approval from MassSave/RISE program) or after the work is completed you can build up the flooring with 2x6 boards to allow extra space. Run the boards perpendicular with existing joists.
Basement or crawl space insulation is one of those areas that tend to get overlook. Adding insulation to basements or crawl spaces can prevent unwanted air infiltration from entering the home to affect thermal management.
Basement ceiling insulation is important to keep cold air out and floors warm on the first floor. Rim Joists are basically an extension of your main floor walls into your basement. Cold air will quickly convent through the thin wood. Rim Joist should be sealed and insulated.
The crawlspace underneath your home can become a problem for regulating temperatures. The crawl space area of your home is extremely vulnerable to deterioration and moisture due to direct contact with the soil. Soil has a high level of humidity, contributing to the problems within this type of space, making it ideal for mold and mildew growth, as well as an attractive living space for rodents and pests.
The natural airflow of a structure goes from bottom to top, which means that the air in your basement or crawlspace will naturally flow up and into the rest of your home. This includes moist air, along with all of the unhealthy elements contained within it. The best way to keep the air from your crawl space from entering your living areas is to seal all air leaks and spaces.
