Weatherize your home in 5 easy steps.

STEP 1: Choose the right caulk so you don't have to do this again and again.

Sealing air leaks around windows, doors, attics and basements with caulk helps keep the harsh outdoor elements out while locking valuable energy savings in. But exposure to moisture, extreme temperatures and the sun’s UV rays can cause acrylic caulk to lose its flexibility and degrade. Instead, go with a 100% silicone or paintable silicone caulk. GE-branded silicone caulks can help stop costly air leaks with a long-lasting, flexible, waterproof seal that never shrinks or cracks.

Acrylic caulks and so-called “silicone-tough” acrylics can harden, crack and crumble over time, so they may need to be replaced to prevent air leaks and energy loss. Think about it: If you can wash caulk off with a little soap and water, how long will it withstand the forces of nature?

STEP 2: Clean the surface.

Remove old caulk, dirt and loose particles. Typically, the caulk needs to be cut, scraped or chipped away using a utility knife, putty knife or painter’s multi-tool.

STEP 3: Open the tube and seal.

Cut nozzle of your caulk tube to the desired bead size. Pierce inner seal with seal punch found on most caulk guns. Insert cartridge into caulk gun. Squeeze with even, consistent pressure to control the rate the caulk leaves the tube.

Tip: Apply masking tape to either side of a joint to create a straight edge before applying caulk.

STEP 4: Smooth the seal.

Use your finger or wet caulk-smoothing tool to smooth caulk into joint within two to five minutes.

Tip: If you applied masking tape in the previous step, remove immediately after smoothing the seal.

STEP 5: Clean up.

Before caulk cures, wipe away excess sealant on surface, hands and tools with a dry cloth.
