If you have water leaking under a commercial door, the issue is usually not the door itself - it’s thethreshold profile (too low, too flat, worn out) and/or missing bottom sealing components.When the threshold is wrong, rainwater and wind-driven water will push right through the opening.
This problem solver shows you how to identify the cause, what to measure, and whichcommercial door threshold solutions stop water intrusion the fastest.
To choose the correct threshold solution, measure:
Designed specifically for exterior commercial openings exposed to rain, snow, and standing water. These profiles improve sealing while maintaining a safe transition at the doorway.
Best when water intrusion is heavy or when the door bottom gap is too large for a standard saddle threshold. Taller profiles create a stronger barrier and better coverage.
For the best performance, pair the correct threshold with a commercial sweep. The threshold blocks water at the floor line; the sweep seals the moving door edge.
If water is coming under a storefront aluminum / narrow stile door, it’s often because a generic flat thresholdwas installed instead of a storefront-specific profile. Storefront systems typically seal best withthresholds designed for glass entry applications.

If this door is part of an accessible route, you may need a solution that stops water while maintaining ADA-friendly height and transitions.If an inspector is involved, start with ADA compliant options and build weather sealing around that requirement.
Shop ADA Compliant Commercial Door Thresholds
Start with Exterior / Weatherproof Thresholds. If the leak is severe or the gap is large, move up to aTall / High Profile threshold and pair it with a commercial door sweep.
