Why Do Exterior Doors Swell and Stick in Brandon, FL Rainy Season?

What Is Actually Happening When The Door Starts To Bind

If an exterior door in Brandon begins to bind, stick, or miss the strike plate during rainy season, moisture is usually involved.

• That is especially common when hardware has loosened over time.
• Paint is cracking, blistering, or peeling at the edges, which tells you the finish is letting moisture in.

That is when it makes sense to look beyond a simple plane-and-paint fix.

Small Fixes That Actually Help

When Replacement Makes More Sense Than Another Repair
