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.
