Change your furnace filter, humidifier and water treatment system filters on a regular schedule, and make a notation on your calendar when they were changed. Make a list of items that need routine maintenance and up-keep. Perform a regular checkup on the exterior of your home, including: roof, walls, caulking around the windows and doors, septic system, walks, driveways and patios. Purchase two (2) fire extinguishers to keep on hand. Put one in the kitchen and one in the garage. Make sure your smoke detectors are working and have fresh batteries installed. Also you should have at least one Carbon Monoxide alarm. Keep a couple of flashlights handy with fresh batteries in convenient and easy to reach locations, and you should always have a well-equipped first-aid kit. Remember that everyone has limitations. Don't be afraid to call your home inspector or a qualified contractor if you have a question or a specific problem. A little effort now will save a big expense in the future!
