Prescriptive Air & Duct Sealing

Reducing the amount of air leakage in your home, especially by sealing the ducts of your forced-air heating and cooling system, is a cost-effective way to cut heating and cooling costs, improve the longevity of your home and make your home more healthy and comfortable for you and your family. According to the Department of Energy, the average home has enough air leakage to add up to a two-foot-square hole – that’s like leaving a medium-sized window open 24 hours a day!

Clean Crawls provides prescriptive air sealing services, including interior sealing and caulking services. Most importantly, we specialize in properly sealing your air ducts.

In houses with forced-air heating and cooling systems, ducts are used to distribute conditioned air throughout the house. In a typical house, however, about 30% of the air that moves through the duct system is lost due to leaks, holes, and poorly connected joints. The result is higher utility bills and difficulty keeping the house comfortable, no matter how the thermostat is set.

When do I need services?

How do I know if I have poorly performing ducts?

Chuck Henrichsen

If you have high summer and winter utility bills, rooms that are difficult to heat or cool and stuffy rooms that never seem to feel comfortable you have poorly performing ducts.

Where does air in my home leak from?

Chuck Henrichsen

Air usually leaks from the floors, walls, ceiling and ducts in your home.

Increase Comfort

Get rid of those uncomfortable drafts! Air sealing and insulating your ducts can help with common comfort problems, such as having rooms in your home that are too hot in the summer or too cold in the winter. Save money by properly sealing the holes in your home to maintain a steady temperature.

Improve Your Air

Fumes from household and garden chemicals, insulation particles, and dust can enter your duct system, aggravating asthma and allergy problems. Sealing ducts can help improve indoor air quality by reducing the risk of pollutants entering ducts and circulating through your home

Be Safe

During normal operation, gas appliances release combustion gases (like carbon monoxide) through their ventilation systems. Leaky ductwork may cause “backdrafting,” where these gases are drawn back into the living space, rather than expelled to the outdoors. Sealing leaks minimizes this risk.

What We Offer

Assess Your Ventilation Needs for Indoor Air Quality

It’s important to ensure that your home has the proper amount of ventilation so it can breathe properly and ensure that the air in your home is healthy.

Once your home has been assessed and we know where the leaks are, we can seal your home properly to ensure that your home is healthy and working efficiently.

Forced Air System Duct Sealing

Air ducts are a very important part of your house. Many homeowners are under the impression that duct maintenance starts and ends at cleaning. However, air ducts are far more complex and require sealing to remain an effective air passage system.

Duct sealing is the process of restricting the gaps and cracks in your duct which account for air and energy loss. Sealing off these gaps reduces the amount of work your HVAC units have to do, increasing energy efficiency as a result.

We do the work you don’t want to!

Air Sealing Products

Once the cracks and leaks have been found, there are different types of products that can be used to address different types of air leaks. These include caulking, spray foam, and weather stripping for sealing smaller leaks. Rigid board insulation or similar products are also used for covering larger holes, while sheet metal and high-temperature caulk is used to close gaps around chimneys and furnace flues.
