A leaky house is聽significantly聽less energy efficient than a聽correctly聽sealed one.聽Being familiar with聽how to聽find聽air leaks in your house, sealing those leaks and scheduling a home energy assessment when聽necessary聽can help you聽create聽a聽relaxing聽living environment and聽decrease聽your energy bills.

Detecting Air Leaks from Inside Your Home

Start聽your air leak inspection on the聽interior. Here are four聽reliable聽techniques聽for聽locating聽air leaks in your house:

Conduct聽a聽comprehensive聽visual inspection, looking for gaps and cracks聽in and around聽windows, doors, electrical outlets and baseboards. Pay聽special聽attention to the corners of rooms,聽because聽gaps can聽frequently聽be found there.
Put聽your hand聽near聽potentially leaky聽places聽on a cold or windy day. If you聽feel聽a draft, you’ve聽found聽an air leak.
Complete a聽smoke test by lighting an incense stick or smoke pen. Then, slowly move it聽near聽the edges of windows, doors and other potential聽problem areas. If an air leak聽is occurring in this location, the smoke will blow around or get sucked聽into聽the gap,聽showing聽the location of a leak. The smoke test is聽most effective聽when聽conducted聽on a windy day.
Use聽an infrared thermometer or thermal camera to聽identify聽temperature differences聽around聽your home.聽These devices聽help you聽locate聽rooms聽with聽major聽temperature variations, which often聽are caused by聽air leaks.

Detecting Air Leaks from Outside Your Home

Studying聽the聽outer聽structure can also聽expose聽potential leaks. Here are two聽methods聽for聽discovering聽air leaks from the outside:

Perform聽a visual聽examination, paying close attention to corners and聽places聽where different materials meet.聽Search聽for gaps or cracks that could聽create聽air leaks, as well as聽deteriorated聽caulk or weatherstripping and聽improperly聽sealed vents and exhaust fans.
Conduct聽the garden hose test on a聽cool聽day. This is where someone sprays water from a garden hose onto the聽exterior聽while another person stands inside聽near聽a suspected air leak. If there’s a leak, the person inside聽should聽feel cold air or moisture聽entering聽through the gap.

Sealing Air Leaks

After聽pinpointing聽major聽air leaks, it’s time to聽handle聽the issue. Here are the聽best聽strategies for聽sealing air leaks in your home:

Use聽caulk to seal small gaps and cracks around windows, doors and other areas where air is聽leaking out.聽Pick聽a聽high-quality, long-lasting caulk聽created聽for indoor or outdoor use and the specific materials聽you are trying to seal聽to ensure a durable seal. Follow the manufacturer’s聽instructions聽for聽correct聽application and curing time.
Apply weatherstripping to doors and windows to help them close tightly.聽Different kinds聽 of weatherstripping are聽sold in stores,聽such as聽adhesive-backed foam tape, V-strip and door sweeps.聽Pick聽the聽correct聽style for your needs and follow the installation聽guidelines.
Use expanding foam to fill and seal聽more substantial聽gaps and holes. Expanding foam聽comes聽in a can with a spray applicator for聽simple聽application in hard-to-reach聽spots. Wear protective gloves and聽stick to聽the manufacturer’s聽directions聽to聽make sure you use them carefully.
Install聽insulation to newly sealed walls and attic floors to further聽minimize聽heat transfer.聽Even when聽you already have some insulation, consider upgrading to a higher R-value or adding more insulation where聽your current level is inadequate.
Put聽door sweeps along the bottom of聽external聽doors to聽prevent聽drafts. Door sweeps are聽sold聽in various materials and聽styles聽to聽suit聽your聽requirements聽and aesthetic preferences.

Considering a Comprehensive Home Energy Assessment

A home energy assessment is聽valuable聽for聽identifying聽hidden聽air leaks and聽identifying聽areas of improvement. A professional energy auditor聽does聽this inspection, which聽involves聽the following:

A blower door test聽entails聽setting up聽a temporary door with a聽sturdy聽fan over an exterior door opening. The fan pulls air聽away from聽the house, lowering the聽interior聽air pressure and聽pulling in聽outside air through unsealed openings. This test measures your home’s air tightness and makes thermal camera images聽show leaks more clearly.
Infrared imaging helps the energy auditor聽locate聽temperature聽inconsistencies聽in the walls, floors and ceilings, revealing聽hidden聽air leaks and insulation聽gaps.
A combustion safety test聽makes sure聽your home heating system, water heater and other combustion appliances are operating safely and聽effectively,聽reducing聽the risk of potentially聽deadly聽carbon monoxide buildup.
A homeowner interview is when the energy auditor聽analyzes聽your energy usage habits, home maintenance history and comfort聽challenges聽to聽spot聽additional energy-saving聽opportunities.

Schedule a Comprehensive Home Energy Assessment

While聽carrying out聽your own air leak tests is聽an excellent聽launching聽point,聽talking everything over聽with a professional is far more thorough. 黑料社区 can help you improve your home’s air tightness with聽a detailed聽home energy assessment and聽tailored聽solutions to聽maximize聽efficiency聽and comfort.
