Draft Sealing & Caulking
Detailed Description
The Drafts in Your Toronto & GTA Home Are Costing You on Every Heating Bill
Air sealing is one of the highest return-on-investment improvements available to Toronto & GTA homeowners — and one of the most consistently underestimated. Gaps at baseboards, plumbing and electrical penetrations through walls and floors, unsealed gaps behind outlet boxes, and spaces at window and door casings collectively account for a significant portion of heating and cooling loss in most Toronto & GTA homes. Unlike insulation, which resists heat transfer, air sealing prevents heated air from leaving and cold air from entering directly. On a Toronto & GTA heating bill in January, that distinction matters.
At CNG Contracting, draft sealing and interior caulking in Toronto & GTA is done systematically — identifying all significant air infiltration points and sealing them with the correct product for each application. Not a tube of bathroom caulk along the baseboards. The right acoustic sealant, fire-rated caulk, or paintable interior caulk for each specific gap and location in your Toronto & GTA home.
Where Air Infiltration Happens in Toronto & GTA Homes
- Baseboard and Floor Junction: Gaps between baseboards and flooring are a direct path for cold air from crawl spaces and unheated cavities — particularly in Toronto & GTA homes with older wood framing that has shrunk over decades.
- Electrical Outlet and Switch Boxes: Exterior wall outlet boxes in Toronto & GTA homes are often a major cold air infiltration point — the cavity behind them connects directly to wall insulation gaps and exterior sheathing.
- Plumbing and Mechanical Penetrations: Gaps around pipes, ducts, and conduit through floors, walls, and ceilings are significant air infiltration paths that are almost never sealed in existing Toronto & GTA construction.
- Interior Window and Door Casing: Gaps behind window and door casings connect to the rough opening cavity — a direct path between inside and outside in Toronto & GTA homes.
Why Systematic Air Sealing Works Better Than Spot Treatment in Toronto & GTA
- Air moves through the path of least resistance — sealing one gap without addressing adjacent ones redirects rather than eliminates infiltration
- The energy saving benefit in Toronto & GTA homes is cumulative — many small gaps together equal a significant opening in the building envelope
- Properly air-sealed Toronto & GTA homes are more comfortable, not just more efficient — cold floors and drafty rooms are air infiltration symptoms, not just heating problems
Draft sealing in your Toronto & GTA home is one of the fastest-payback improvements you can make on your heating costs. Book your visit today and let’s find where the air is moving.

Frequently Asked — Draft Sealing in Toronto & GTA
How much can air sealing reduce heating costs in a Toronto & GTA home?
Estimates vary, but Natural Resources Canada cites air sealing as one of the highest-impact single improvements for existing homes. In older Toronto & GTA homes with significant infiltration, the improvement can be measurable on utility bills within the first heating season. We don’t promise specific savings — but we seal what we find and the results speak clearly in most cases.
Is draft sealing the same as weatherstripping?
Related but distinct. Weatherstripping seals operable gaps at doors and windows. Draft sealing addresses fixed gaps at penetrations, baseboards, and building envelope intersections throughout your Toronto & GTA home — typically more numerous and often more significant than operable gap infiltration.
How do I book draft sealing in Toronto & GTA?
Book online in under two minutes. Our Toronto & GTA team contacts you directly to confirm scope and schedule.
For Toronto & GTA homeowners considering a more comprehensive energy audit alongside draft sealing, we note that professional air sealing as done here is often the highest-return single measure identified in energy assessments — and completing it independently of a formal audit still delivers the energy performance benefit.
Why is a Technical Visit necessary?
Simply applying new caulk over old, cracked sealant is a recipe for failure. The new layer won't adhere properly, leading to continued leaks. Our Draft Sealing & Caulking assessment identifies where old material must be scraped away and the surface primed. We also determine if backer rods are needed for wide gaps to prevent the sealant from failing due to expansion and contraction.
