Cleaning the glass
Clean impact glass like any quality window: mild soap and water, soft cloth or squeegee, no abrasive pads. Avoid harsh chemicals and razor blades on coated (low-E) surfaces — the coating is on the glass and scratches are permanent. Clean in the shade when you can; soap dries too fast on hot Florida glass and leaves streaks.
Tracks and weep holes
Sliding windows and doors run on tracks that collect Central Florida's finest: sand, oak pollen, and grit. Vacuum tracks a few times a year and wipe them down — gritty tracks wear out rollers. Weep holes (the small drain slots at the bottom of frames) must stay clear so rain drains out instead of pooling in the frame. A toothpick or pipe cleaner clears them in seconds.
Seals and weatherstripping
Once a year, walk the house and look at the seals: cracked, flattened, or peeling weatherstripping lets air and water in. Replacing weatherstripping is cheap and easy. Check the exterior caulk lines too — Florida sun and rain break caulk down over the years, and fresh caulk keeps water out of your walls.
Hardware
Operate every window and door at least twice a year — locks, cranks, and sliders that sit unused get stiff. A drop of silicone lubricant (not oil, which attracts dirt) on moving parts keeps everything smooth.
After a storm
Once it's safe, check each window: look for cracked glass, damaged screens, and water intrusion around the frames. Impact glass can take a hit and hold — but a cracked pane should be replaced, since its storm strength is reduced. Document any damage with photos for your insurance.
