Sealed for Sustainability

Stay comfortable inside and keep the rain, drafts and pests outside with 100% weatherproof GE-branded Window & Door sealants.

Sealing exterior gaps and cracks with a durable, 100% weatherproof sealant is essential to your home’s long-term durability. Not only will you seal out damaging water and pests, you’ll also seal in your home’s A/C and heating, helping you save energy and stay comfortable year-round.

Check the seals around your windows, doors, siding, HVAC and other common sealing areas at least once a year. Replace old or damaged seals as needed to ensure your home is protected and ready to stand up to the changing weather through every season.

How Sealing Can Help Protect Your Home and Save Energy

Keep your home protected and enjoy more sustainable energy savings through each season by properly sealing exterior and interior gaps, cracks and joints. Here’s where to start:


Seal around windows, doors and other exterior openings with a 100% waterproof Silicone sealant to prevent leaks and water damage during the rainy seasons.


Fill and seal gaps around windows, doors and HVAC penetrations with a weatherproof and flexible sealant to reduce air leaks and improve your home’s insulation, keeping it cool in the summer and warm in the winter while your energy bills stay low.


Seal any gaps or joints that are exposed to water, moisture and humidity with a mold-resistant sealant to prevent mold, mildew and fungal growth and keep your home durable and beautiful.


Seal and block potential pest entry points with a 100% Silicone sealant that won’t shrink or crack over time to get long-lasting protection against troublesome pests.
