How to Recaulk and Weatherproof Your Home
Pull the old caulk
New caulk over old, cracked, or moldy caulk fails fast. Cut and scrape it all out, kill any mildew, and let the gap dry. The removal is the tedious part and the reason it lasts.
Right sealant for the spot
Use 100% silicone in wet areas — tub, shower, sinks — because it stays flexible and waterproof. Use paintable siliconized acrylic on trim and windows so you can paint over it. Don’t put non-paintable silicone where it needs paint.
Weatherstrip the drafts
Add door sweeps, weatherstripping and threshold seals where you feel air move. In Florida that keeps your cooled air in and the humidity and bugs out — you feel it on the next power bill.
Why it matters here
Water intrusion plus our humidity equals mold and rot; unsealed gaps let bugs and hot air in. A whole-home seal protects the house and your AC budget. Want it done in one pass? We reseal and weatherproof across Broward.
Frequently asked
Silicone or acrylic caulk?
100% silicone for wet areas like tubs and showers; paintable siliconized acrylic for trim and windows you’ll paint over.
How often should I recaulk?
Tub and shower caulk every few years, or sooner if it cracks, peels or grows mildew. Catching it early prevents water damage.
Will sealing help my AC bill?
Yes — weatherstripping doors and sealing gaps keeps cooled air in and humidity out, which eases the load on your AC.
How do I deal with mold in the caulk?
Remove the caulk entirely, clean and dry the area, and reseal with mildew-resistant silicone — you can’t just caulk over mold.
