Commercial Waterproofing for Entrances & Door Frames
Commercial grade waterproofing that keeps rain out of your entrances, door frames, and the building behind them. Serving MD, DC & Northern VA.
What happens when an entrance is not waterproofed?
Doorways are cuts in the building envelope, and every cut is a place water wants in. When the seal around a commercial entrance fails, the damage rarely announces itself right away. Water wicks into the joint between frame and wall, sits at the base of the frame, and works on the materials quietly: steel frames rust from the bottom up, flooring near the threshold lifts and stains, and the wall around the opening grows damp patches that keep coming back no matter how often they get painted over.
By the time a puddle shows up inside the lobby after a storm, the leak has usually been working for a long while. That is why we treat waterproofing as door work, not an afterthought. Protecting the opening protects the door system, and we are a company that installs, repairs, and maintains those systems every day.
How we waterproof a commercial entrance
We seal the entrance as a complete assembly rather than chasing single drips. That means the frame perimeter where it meets the wall, the threshold where the door meets the floor, and the transitions around the opening, all with commercial grade materials made for exterior exposure.
- Entrance and door frame perimeter sealing
- Threshold protection where water pools first
- Commercial grade materials suited to exterior openings
- Honest assessment when a frame is past sealing and needs repair instead
If the water has already done its damage, the fix may involve more than sealant. A rusted out frame is a job for our hollow metal door and frame work, and a full entrance rebuild can lean on our demolition and hauling and disposal services so one crew carries the project from tear out to sealed and finished.
Waterproofing questions, answered
What property owners ask us about leaking entrances.
Why is water getting in around my commercial door?
Water finds the weakest point of an entrance, and that is almost always a seam: the joint where the frame meets the wall, a threshold that no longer seals against the door bottom, or sealant that has dried out and cracked. Once one of those gives, every rain pushes water into the opening. Waterproofing the entrance closes those paths before the water widens them.
What does door frame waterproofing include?
It means sealing the entrance as a system: the frame perimeter, the threshold, and the transitions where the doorway meets the surrounding wall, using commercial grade materials meant for exterior openings. The goal is simple, water stays outside the building envelope instead of tracking into the frame, the floor, and the wall around the door.
Can waterproofing save a rusting hollow metal frame?
If the rust is caught early, yes. Steel frames rust from trapped moisture, usually at the base where water sits. Sealing out the water stops the process from feeding. If the frame is already rusted through, waterproofing alone will not bring it back, and we will tell you honestly when a repair or replacement is the smarter spend.
Do you only waterproof doors you installed?
No. We waterproof entrances and door frames on existing commercial buildings regardless of who installed the doors. It pairs naturally with our repair and maintenance work, since a leaking entrance and a failing door usually show up together.
