What to Know About Duct Sealing & Insulation:
Duct Sealing and Insulation Process
During our initial consultation to evaluate your duct sealing and insulation situation, the estimator will assess the ductwork to see its current condition. At this time, Crawl Pros estimators will confirm if your ductwork needs a repair or replacement. We’ll let you know if you qualify for any utility rebates.
When the crew comes out for the job, they will go section-by-section throughout your house, performing duct sealing and insulation or replacing your ductwork to utility company standards.
Tasks may include:
- Removing any old insulation and tape that may be on the ducts
- Securing ducts with screws and sealing all joints with mastic. Mastic is a flexible sealant that contracts and expands with your ducts and will never come off, unlike tape
- Replacing any duct lines or joints that are too damaged to be sealed with mastic or other traditional methods
- To complete the project, installers will spiral wrap the ducts to building code, with R-11 insulation. They will then spiral nylon string/fiber tape around the insulation to permanently hold it in place.
Is Duct Sealing & Insulation Worth it?
There are a few key things to consider when addressing your ductwork. First, ductwork is the delivery system of your home. Maintaining your ductwork sets your house up for success. Insulating ducts also reduces the load on your furnace, which could save you hassle and money later down the road.
If not sealed, ducts can become contaminated with rodents. Rodents are known to nest on uninsulated ductwork.
It Makes Financial Sense
Sealed and insulated ducts can lead to up to 35-40% savings on your energy bill due to the efficiency of well-maintained ducts. Enduring another winter with leaky air ducts leads to higher utility bills. If you continue to use your ducts in the summer, you’ll be losing valuable air from inadequate duct sealing.
Some utility companies offer rebates to ensure homeowners have efficient ductwork.
