The first step towards air sealing your home that you need to take is to assess your home for leaks. Here, you need to check every nook and cranny of your house to identify all the spots for air leakage. However, before you can “seal the deal,” you need to understand the deal here.

You can use various tools like a laser thermometer to detect air leaks in homes. You can use this to detect places around your house where temperature changes rapidly, especially during winter. 

You can also use traditional ways to detect air leaks like a candle. This is the best way to detect leaks in windows and door hinges. Hold the candle near these areas and just wait. If you see it flicker or blow out, it means there is a leak.

The most common places where air leakages tend to happen the most are:

  • Switch plates.
  • Phone lines.
  • Chimneys and fireplaces.
  • Door and window frames.
  • Floorboards.
  • Ceiling fans.
  • Basement doors.
  • Attic doors.
  • Wall-mounted AC Units.
  • Vents and baseboards.

Step 2. Seal The Attic

Seal The Attic

The attic is one of the most common places where a lot of air leakage occurs. This is why you need to prioritize air sealing up there. This is because most outlets for electrical wirings in your rooms go up to the attic to converge. This creates lots of scope for air to leak out from these holes. This also includes small solar panels you might have fit on your terrace.

If you wish to learn how to maintain humidity in the room, you can start by air-sealing your attic. You can do so by blocking leakages using a foam spray. You can also use this for windows and door hinges as well.

Step 3. Seal Your Basement

Seal Your Basement

Our basement might be a scary place to head down to. This is dark and gloomy, with a musty smell. Air leakages are common because of HVAC systems, heating ducts, drying vents, electrical wiring, and lots more. 

Because of such leakages, it’s important to learn how to maintain room temperature in rooms directly above your basement. Therefore, air sealing your basement will make it warm and your rooms cold in summer (and vice versa in winter). 

Step 4. Exterior Air Sealing

When it comes to exterior air sealing, chimneys and fireplaces are the first places you need to seal. In these places, cracks and more can appear over time which can cause air leakage. Air sealing these places will ensure that no air passes through, helping you maintain the room’s temperature.

Various sidings and other areas of chimneys where structures collide can lead to air leakages. Therefore, if you are weather-sealing these places, do so carefully since these cracks can be pretty big. However, you will only see a portion of these cracks on the inside, making it difficult to assess.

Step 5. Interior Air Sealing

Windows are the most susceptible areas when it comes to interior air leakages. Therefore, air-sealing your windows tightly is a must in all homes. This is mostly because air can leak from the sides of the windows, especially near hinges.

Here, you can use foam gaskets and foam sprays to seal up any small leaks that can appear on windows and doors. Also, ensure no gap is left between the floor and the bottom of your door. This is one of the most overlooked air leaks.

2. Weatherstripping

3. Insulation

Insulation

DDC room pressure should be maintained – always. Therefore, to ensure that it is maintained, room insulation is necessary.
