Professional Ottawa Air Sealing Services

Even the best contractors can’t build a fully airtight home or building – there will undoubtedly be gaps and cracks that facilitate air leakage, especially in older homes. Joints, plumbing, and electrical work create gaps and spaces that allow air infiltration and leakage. Spray-Tech Insulation offers add-on air sealing packages when we perform insulation work at your home, to help you eliminate air leakage issues and improve your home’s energy efficiency.

Air Sealing

How Air Leakage Affects Your Home

Air leaks can cost you thousands of dollars in heating and cooling costs over the lifespan of your home. Warm air in your home finds its way out through cracks, gaps, and holes while cold air gets through these tiny spaces.

An unsealed home or building is like leaving an open window on a cold winter night or a hot summer day. In both instances, you force your HVAC system to work harder to heat or cool the air in your home.

Air leakage is something of a double whammy – it results in soaring utility bills and a less comfy indoor environment. As warm air works its way out of your home, cold air finds a way in. That explains the chilly drafts or uneven temperature zones in your home.

Air leaks could also be the reason for dust, allergens, and musty odors in your home. Contaminated air entering your home through cracks and holes could result in poor indoor air quality and respiratory issues.

Our air sealing package pinpoints air leaks in places that work is being performed, and helps to seal your home to increase energy efficiency and create a comfortable indoor environment. Our methods include sealing rim joists with spray foam, ensuring vapor barrier is properly installed and all electrical and plumbing joints in the work area are sealed.

Signs You Need Air Sealing Services

Detecting air leaks isn’t always straightforward – you will need energy professionals to run tests and identify air leakage culprits in your home. However, watch out for the following telltale signs that often indicate air leakage.

  • Cold spots and hard-to-heat rooms.
  • Chilly drafts in your house.
  • Rising energy bills.
  • Dust and mouldy odours in your house.
  • Ice dams or large icicles hanging from the eaves during winter.

Once a trained, energy professional has completed as assessment, sharing the results with Spray-Tech ensures that we can assist with air sealing whilst performing insulation work in your home.

Common Air Leakage Trouble Spots

Most contractors do a stellar job of building a comfortable, energy-efficient home. Yet, they can’t guarantee that your home or commercial building will be 100% airtight for the simple reason that there are many spots through which air leaks into and out of your house.

The critical areas for air sealing we inspect whilst performing insulation work include:

Air Sealing
  • Attics

    More air leaks in and out of the living areas through the attic than anywhere else. That is especially the case in wood frame homes. Potential leakage points in the attic include dropped soffits, where the ceiling is interrupted, or its height varies.

    Attic air leakage could also result from spaces close to the chimney, ducts, plumbing penetrations, light fixture boxes and wiring holes. Attic interior and exterior walls and joints are also possible air leakage points, while knee walls, doors, and hatches associated with the attic shouldn’t be ignored.

    Leaky attics could also be behind moisture problems in your house. When humid air makes its way to the attic through leakage paths, it may condense and compromise your insulation’s quality

  • Basements

    The basement’s most obvious air leakage point is where the concrete wall meets the wood frame. There are also multiple cavities where the floor joists meet the rim joists, which create possible points of air leakage.


Other common air leakage points that may need sealing include:

  • Ducts
  • Around exterior doors and windows.
  • Electrical outlets and switches on exterior walls.
  • Cracks, holes, and gaps in drywall or plaster.
  • Basement windows.
  • Scuttle holes and pull-down stairs.

If Spray-Tech is performing insulation in your home and notices air leakage points outside our scope of work, we will make sure to mention them to you so you can take the correct steps to ensuring your home is as air tight as possible.

How Sealing and Insulation are Intertwined

Most homeowners understand the importance of insulation and the dangers of air leakage. However, most don’t know that neither air sealing nor insulation alone is enough to curb air infiltration and leaks. We are crusaders of air sealing in addition to insulation installation or reinforcing your existing insulation.

Our contractors prioritize sealing the attic since it is where the most air leakage occurs. The basement and crawl space come second. By sealing these spaces, we eliminate major culprits of air leaks.

Installing spray foam insulation in these areas complements air sealing efforts since it forms an air barrier that prevents air infiltration and exfiltration. Air sealing services go hand-in-hand with insulation to ensure that your home is airtight and keeping your heating and cooling bills low.
