1. Caulk it up: Fuller keeps at least 15 tubes of clear seal and peel caulk in his house at all times, which he uses to seal up his garage door, dryer vent, outdoor outlets and anywhere else water can get in.
He recommends an electric or battery-powered caulking gun to get the job done quickly.
2. Sewage stopper: A backwater check valve can stop a crappy situation if sewage backs up in high-water conditions.
If you install it yourself, which Fuller recommends to save on sky-high plummer fees, it'll cost you around $43.
3. Sliding door saver: A $100 PVC board could stop water from coming through your sliding doors and causing a much pricier mess.
Caulk around the edges of the PVC to keep it in place. Once the storm is over, peel off the caulk and keep the board to do it again as many times as you need.
