Regularly clean gutters and downspouts. Make sure all drainage areas are unblocked by leaves and debris. Consider installing gutter guards to make the job a lot easier.
Use a screwdriver to probe the wood trim around windows, doors, railings and decks. Use caulk to fill the holes or completely replace the wood.
Lower humidity and cooler (not yet cold) temperatures make fall a good time to paint the exterior of your home.
Inspect your roof, or hire a licensed professional to examine your roof for wear and tear. If the shingles are curling, buckling or crackling, replace them. If you have a lot of damage, it’s time to replace the entire roof. Also, check the flashing around skylights, pipes and chimneys. If you have any leaks or gaps, heavy snow and ice will find its way in.
To prevent exterior water pipes from bursting when the weather gets below freezing, turn off the valves to the exterior hose bibs. Run the water until the pipes are empty. Make sure all the water is drained from the pipes, if not; the water can freeze up and damage the pipes.
Doors and Windows
The change in temperature and humidity and normal wear and tear can cause window seals to crack and shrink.
Check your windows and doors inside and out for leaks and drafts.
Caulk cracks or install weather stripping around windows and doors, including the garage door.
Replace screens with storm windows and clean them if needed.
