Door cup guards that prevent water pooling and rust
Precision-fit guards that block water and road salt from collecting in door cups, keeping your interior dry and your frame protected from corrosion.
Simple shields with a big payoff
Door cup guards are custom-molded protective shells that sit inside your vehicle's door frame openings. They trap water, debris and road salt before they pool and cause rust, mold and interior damage. Installation takes an afternoon and transforms how your doors weather the elements.
They're especially valuable if you park outside or wash regularly, since both flood door cups with water. Guards let moisture drain away harmlessly instead of settling into seams where it degrades metal and rubber gaskets.
Dry doors and rust-free frames
Water pooling in door cups is the fastest way to rust. Guards prevent it entirely.
Stops water pooling
Instead of collecting in exposed cavities, moisture drains safely away before it pools.
Prevents rust and corrosion
No standing water means no rust forming on vulnerable frame metal and door hinges.
Protects weatherstripping
Rubber gaskets and seals stay dry, so they don't degrade, swell or develop mold.
Keeps interiors dry
Water won't seep into door panels, carpet and electronics through open cup gaps.
Reduces interior odors
Trapped water breeds mold and mildew; guards eliminate the source entirely.
Long-term resale value
Protecting frame and interior from water damage preserves your vehicle's structural integrity and appeal.
How we fit and seal them
Proper fitting means guards stay in place and water drains exactly where it should.
Assess and measure
We inspect your door frames, check cup geometry and measure openings to ensure a perfect fit.
Prepare surfaces
Door cups are cleaned and prepped so the guard seals completely and adhesive bonds securely.
Install and align
Guards are fitted precisely into each cup and aligned to ensure proper drainage and no obstruction.
Seal and test
All seams are sealed with marine-grade weatherproofing, then we test water flow to confirm everything works.
