1- Drain your irrigation system. Even buried irrigation lines can freeze, leading to busted pipes and broken sprinkler heads.
- Turn off the water to the system at the main valve.
- Shut off the automatic controller.
- Open drain valves to remove water from the system.
- Remove any above-ground sprinkler heads and shake the water out of them, then replace.
If you don’t have drain valves, then hire an irrigation pro to blow out the systems pipes with compressed air. A pro is worth the $75 to $150 charge to make sure the job is done right, and to ensure you don’t have busted pipes and sprinkler head repairs to make in the spring.
2- Seal the drains– Grab a couple of tubes of color-matched exterior caulk ($5 for a 12-ounce tube) and make a journey around your home’s exterior, sealing up cracks between trim and siding, around window and door frames, and where pipes and wires enter your house. Preventing moisture from getting inside your walls is one of the least expensive — and most important — of your fall maintenance jobs. You’ll also seal air leaks that waste energy.
Pick a nice day when temps are above 50 degrees so caulk flows easily.
3- Check Your Gutters –Clogged rain gutters can cause ice dams, which can lead to expensive repairs. After the leaves have fallen, clean your gutters to remove leaves, twigs, and gunk. Make sure gutters aren’t sagging and trapping water; tighten gutter hangers and downspout brackets. Replace any worn or damaged gutters and downspouts.
4-Schedule an appointment with a heating and cooling pro. to get your heating system checked and tuned up for the coming heating season. You’ll pay $50 to $100 for a checkup. An annual maintenance contract ensures you’re at the top of the list for checks and shaves 20% off the cost of a single visit. Change your furnace filters, too. This is a job you should do every two months anyway, but if you haven’t, now’s the time. If your HVAC includes a built-in humidifier, make sure the contractor replaces that filter.
