Your Birmingham winterizing calendar
Every date below is counted back from the earliest realistic freeze, October 30. Work through them in order and the pipes are safe even in an early year. If a date has already passed, do that step this weekend.
By October 2: clear the gutters and seal the gaps
Clean the gutters, caulk the window gaps, and replace a worn door sweep so heat stays in and ice doesn't build at the eaves.
By October 16: test the furnace and swap the filter
Run the heat for ten minutes on a mild day so a dead igniter or a tripped breaker shows up now, not on the first cold night. If it won't start, the furnace checklist covers the free fixes first.
By October 30: pull the hoses and drain the faucets
This is the date that matters. Unscrew every hose, close the indoor shutoff, drain each spigot, and cover it. The full routine is in how to winterize outdoor faucets.
After February 28: reverse it in spring
That is the date by which 90 percent of years have seen their last freeze. Open the indoor shutoff and check the wall behind each spigot for a split pipe before you trust it.
