Start with the house

This guide covers four accessible product types. The right one depends on where the air is moving.

Shopping note: We have not personally tested these products. Canadian Tire links are currently non-affiliate.

Before buying

Three checks first

Find the path

Check windows, exterior doors, baseboards and wall plates. A draft is a clue, not yet a shopping list.

Measure the gap

The wrong weatherstripping can stop a window or door from closing. Measure before buying.

Keep vents open

Do not block intentional vents or combustion-air openings.

Four different jobs

Match the measure to the leak

For moving window and door edges

Frost King self-stick V-seal

7/8 in × 17 ft roll

Where it may fit

A narrow tension seal for moving door and window edges.

Before buying

Clean and dry the surface, then test a short section before applying the full roll.

Worth knowing

It can leave residue and may not hold on damp or uneven surfaces.

For a worn exterior-door bottom

Frost King slide-on U-shaped door bottom seal

Fits a 1 3/4 in × 36 in door

Where it may fit

A replacement seal for a compatible exterior door with air moving underneath.

Before buying

Measure the door and confirm that a slide-on profile matches it.

Worth knowing

It will not fix a door that is badly out of square.

For a seasonal window layer

Frost King heavy-duty window shrink film

62 in × 126 in roll-on kit

Where it may fit

A clear seasonal layer over a compatible interior window frame.

Before buying

Measure the full frame and make sure the tape has a clean, sound surface.

Worth knowing

Film limits opening and creates seasonal plastic waste. Keep required exits usable.

For wall plates on exterior walls

Frost King outlet and switch sealer kit

14-piece foam gasket set

Where it may fit

Pre-cut gaskets for air entering around compatible wall plates.

Before buying

Turn off and verify power before removing a cover. Stop if anything is loose, damaged or unfamiliar.

Worth knowing

A gasket does not address unsafe wiring or a larger wall-cavity leak.

Safety

Keep intentional airflow open.

Do not seal vents, exhaust paths or combustion-air openings. For anything beyond a small, obvious repair, consider an EnerGuide evaluation or qualified professional.

One last note

Fix the draft you can identify.

Start small, make sure doors and windows still work, then reassess.
