Proper home weatherproofing can help make your home more comfortable by reducing drafts, limiting moisture intrusion, and protecting vulnerable areas around doors and windows. Small gaps and worn seals are easy to overlook, but they can have a noticeable impact when temperatures change.
The right home weatherproofing supplies can help you seal problem areas before they turn into larger maintenance issues.
Seal Gaps Around Windows and Doors
Drafts around windows and exterior doors are often caused by aging caulk, worn weatherstripping, or small gaps around frames.
A removable weatherstrip sealant can be useful for seasonal sealing. DAP Seal 'N Peel Weatherstrip Sealant is designed to seal drafty windows, doors, vents, and similar openings against air and moisture.

For a more permanent exterior seal, DAP AMP Window, Door & Siding Sealant is made for weather-exposed applications and can be applied to damp or wet surfaces.
Replace Worn Weatherstripping
Weatherstripping helps close the small spaces around moving doors and windows where air can pass through. Over time, these materials can compress, crack, or pull away from the surface.
Replacing damaged weatherstripping is one of the simplest ways to improve a door or window seal. MRO Supreme carries options such as M-D EPDM/Silicone Weatherstrip Tape, designed for sealing gaps around doors and windows.

Stop Drafts at the Bottom of Doors
The bottom of an exterior door can be another major source of unwanted airflow.
A properly fitted door sweep can help block drafts, moisture, dust, and insects. The M-D aluminum and vinyl door sweep, for example, uses a triple-fin seal designed to provide additional protection along the bottom edge of the door.

MRO Supreme also carries additional door sweep sizes and styles for different applications.
Add Extra Protection to Drafty Windows
Older or less efficient windows may benefit from an additional layer of seasonal insulation.
MRO Supreme's hardware selection includes window insulation kits and weatherstrip tape designed to help reduce drafts around window openings.

Don't Overlook Door and Window Hardware
Weatherproofing is not only about sealants.
Loose hinges, worn locks, damaged latches, or poorly aligned doors can prevent a door or window from closing tightly enough to create a proper seal.
Inspecting and replacing worn window and door hardware can help improve both weather protection and everyday operation.
Make Weatherproofing Part of Routine Home Maintenance
Effective home weatherproofing does not require a major renovation. Sealing small gaps, replacing worn weatherstripping, installing door sweeps, and maintaining window and door hardware can help protect your home from drafts and changing weather.
