DUCT SEALING: We can help you get it done!
Air that’s heated or cooled to comfort you and your family shouldn’t be pouring into your crawlspace, attic, walls or other uninhabited areas. That’s why it’s important to make sure your duct heating and cooling systems aren’t leaking, which wastes energy and costs you money and comfort.
How do you know that your home has poorly performing ducts?
- You have high summer and winter utility bills.

- You have rooms that are difficult to heat and cool.
- Your crawl space is warm.
- You have ghosting or dust rings around the duct joints.

Doing duct work and duct sealing your ducts can trim your energy costs. It can also make your home more comfortable and reduce indoor air pollution. Duct insulation can provide even more benefits. Sealed and insulated duct work in addition to a properly sealed and insulated home—also allows you to install a heating system that is the correct size for your home.
Air Sealing a home can also be a great help. Sealing the shell of your home from air leaks is one of the most cost-effective ways to increase your comfort and energy efficiency. The shell includes outer walls doors, ceiling, windows and floors. Having duct sealing done to your home reduces drafts, controls moisture, keeps out pollutants and improves overall comfort. Many air leaks and drafts are easy to find because they are easy to feel. An example is those drafts around doors and windows.
Having us perform a Blower Door test is the only way to find out where the majority of these leaks happen. This test uses a 20 horsepower motor to pressurize and depressurize your house. It then measures your home air leakage, helping you find many of your home’s hidden leaks. We can help you fix them or show you where they are so you can get it done.
How Air Ducts are Sealed:
First thing we do when looking at duct sealing is make sure anywhere two pieces of metal duct work come together they have at least three sheet metal screws holding them together. After that our technicians go through making sure all of the air ducts are supported properly. Anywhere there is a seam, crack, gap or joint in the duct work gets a nickle thick of duct mastic to ensure that all accessible air duct leaks are sealed. Our team does this to the outside and inside vents. Once sealed, R11 insulation is wrapped and attached with twine around the exterior of the ducts. This is usually located in the unconditioned space. Finally after all duct sealing and insulating is complete one of our experts goes through a leakage checklist to make sure that the job meets our standards.
