Minor Weatherproofing
Detailed Description
Small Gaps Around Your Toronto & GTA Home Are Collectively a Significant Energy Loss
Energy audits and full air sealing projects are valuable — but so is addressing the minor weatherproofing tasks that accumulate in every Toronto & GTA home over time and don’t warrant a full project scope. The gap under the back door where the sweep has worn. The caulk around the bathroom exhaust vent on the exterior that’s pulled away from the siding. The mail slot that lets cold air in. The basement window that doesn’t seal when closed. Individually, each of these is a small improvement. Addressed together in a single visit, they represent meaningful improvement to your Toronto & GTA home’s thermal performance and comfort — without the cost or complexity of a comprehensive energy upgrade.

Frequently Asked — Minor Weatherproofing in Toronto & GTA
What’s the difference between minor weatherproofing and a full air sealing project?
Minor weatherproofing addresses accessible, visible infiltration points at doors, windows, and exterior penetrations. A full air sealing project typically involves attic floor sealing, rim joist treatment, and systematic building envelope work requiring more access and time. For most Toronto & GTA homes, minor weatherproofing is a valuable first step that can be followed by more comprehensive work as needed.
When is the best time to book weatherproofing for a Toronto & GTA home?
Before heating season — September and October — is ideal so the improvements perform through winter. That said, infiltration sealing improves performance in any season and is worth doing whenever it’s identified.
How do I book minor weatherproofing in Toronto & GTA?
Book online in under two minutes. Our Toronto & GTA team contacts you directly to schedule.
Minor weatherproofing visits in Toronto & GTA homes are also an opportunity to identify larger weatherproofing issues that deserve attention in a subsequent dedicated service — we document and note everything observed during the visit so nothing that needs attention gets overlooked.
Why is a Technical Visit necessary?
Small leaks add up. The cumulative effect of tiny gaps around electrical outlets, baseboards, and pipe penetrations can be equivalent to leaving a window open all winter. However, using the wrong sealant (like high-expansion foam around windows) can warp frames. Our Minor Weatherproofing assessment identifies these hidden air leaks and selects the appropriate material—whether it's caulk, foam gaskets, or spray foam—to seal them safely without damaging your finishes.
