Severe Weather Guide: Caulk and Seal
Caulking is a quick and inexpensive way to keep rainwater and storm surge out of your house and strengthen vulnerable areas from high winds.
Caulk and Seal These Spots:
1. Seal out storm surge and floodwater.
Caulk wiring and plumbing penetrations, such as lights and outlets, faucets, gas lines and air conditioners, especially near ground level. Large holes can be plugged with electricians putty.
2. Keep out wind-driven rain.
Caulk around all windows and doors.
3. Protect metal soffits from high winds.
Caulk all edges to the house and the fascia (outside of eaves). Renail and caulk any loose pieces.
4. Caulk and refasten loose gutters and downspouts.
Remove and store downspout sections that could be blown away.
5. Keep out heavy rain.
Caulk around chimneys, skylights and other roof penetrations.
Acrylic latex caulk works well for most areas and can be painted to match siding and trim. Apply it with a caulk gun, then wipe it smooth within a minute or two with your finger or a damp rag or sponge.
Silicone is a tough, durable caulk, but color options are limited and it cant be painted unless you buy a special type. Smooth joints immediately with a cloth, caulk- smoothing tool or moistened finger.
Urethane caulk also works well, but is messy to work with.Butyl rubber caulk is the best choice for gutters and downspouts.
Before caulking, clean off dirt and loose paint and fill large voids with foam backer rod.
