1. Gutters and downspouts
Winter ice loads bend gutters and pop gutter spikes. Walk the perimeter — any gutters sagging, pulling away from the fascia, or with visible debris need cleaning and re-hanging. Downspouts should drain at least 6 feet from the foundation; extensions are cheap insurance.
2. Deck and fence
3. Caulking around windows and doors
4. Doors and locks
Lubricate all exterior door locks with graphite (NOT WD-40 — it gums up over time). Check that every storm door closes properly and the closer isn't leaking oil. Re-hang anything that's started to drag during the winter heave/contract cycle.
