How to Caulk Replacement Windows

Caulking replacement windows will save a lot of money on your heating bill. Homes lose the highest amount of heat through the windows and the gaps around them. Different types of caulk are needed for different situations, so having the right type of caulk is important. For the outside of the window a non- expanding foam from DAP works best because the caulk won't push out the frame when it's finished drying. If you are planing on painting or staining the interior of the window frame, then use a caulk that is clear or matches the color of your wood trim.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Caulk (DAP)
• Razor blade utility knife
• Nail or screw
• Paint scraper
• Caulk gun

1. Use the paint scraper to remove any loose material around the edge of the window frame. This must be done on the inside as well as the outside of the window.

2. Take the razor blade utility knife, and cut the top off of the caulk tube. Make sure that the cut is at a 45- degree angle. Doing this will help keep the bead of caulk more even when applying it to the window.

3. Insert the nail or screw into the open end of the caulk, and stir to help loosen the solution. Put the caulk tube into the caulk gun and squeeze the trigger until you see some caulk on the tip.

4. Apply the bead of caulk around the outside perimeter of the window between the vinyl of the window and the wood frame of the house. Make sure that all cracks and holes are filled even with the rest of the bead.

5. Use a rag to wipe off any excess caulk from around the window. Smooth any lumps in the caulk for an even bead all the way around.

6. If painting the interior frame, paint first, then apply caulk around the window between the vinyl window and the wood frame. Make sure the bead is even, and wipe off any excess caulk.

Tips & Warnings
