Spring is a great time to weather proof your home. Warmer weather makes outdoor work more pleasant, there is more daylight, and high winds can trigger drafts throughout the house.
First, check all of the windows for gaps where air can escape or enter. Over time, calking degrades and can come loose. Re-calking now will help keep your energy bill in check before you turn on the air conditioner. Remove any old material and clean well before you apply the calking. If your windows are still drafty after you re-calk, ask a professional for an estimate for weather proofing or energy efficient replacement windows. They will pay for themselves in no time.
Look for gaps around exterior doors. Weather stripping can also degrade and break down over time. Before applying the adhesive striping, make sure to remove all of the old material and make sure the surface is very clean and dry for best results. Measure the door jam and the door to insure you are getting the correct width and length. Also measure any gaps to make sure you are getting the correct thickness.
While you are at it, check your electric outlets for air leaks. Installing foam outlet gaskets will help. These are inexpensive and easy to install.
Spring is also the perfect time to inspect your attic and roof. Winter weather can cause loose shingles, gutters and downspouts. Cold weather also brings damage caused by animals looking for a warm place to nest. If you see any winter wear and tear, call a trusted local professional contractor who can give you an estimate.
