Abstract: Door sealant systems, apparatus, and methods, including: a seal apparatus configured about a door assembly; an air source configured to supply air into the seal apparatus; a plurality of valves including at least a first valve and a second valve, wherein the first valve is coupled to the air source, the first valve configured to inject air into the seal apparatus at a rate slow enough to allow the door assembly to fully close before the seal apparatus expands to push against the door assembly, wherein the second valve is coupled to the seal apparatus, the second valve configured to release air from the seal apparatus at a rate quick enough to allow the door assembly to be opened without damaging the seal apparatus.
