Crawl space spray foam insulation in Beaumont is unusual work, because a town whose housing is mostly post-1991 has very few houses built over a crawl. Where they turn up here they are almost never under the whole building.
Under one section of the house rather than the house
In an older town the crawl is what the house sits on. In Beaumont it is a consequence of a floor plan: a step down into a rear extension, a section built over grade because the ground fell away, a bonus area added at the design stage rather than dug out. That makes it a localised problem rather than a whole-house condition, and it is why the complaint is nearly always one room being cold rather than the building feeling cold. It also means the space is usually small, awkward to get into, and was closed up at framing with no expectation that anybody would return.
A poly sheet that was laid but never lapped
Almost all of these have a ground membrane, because it went in as part of the build. That is a real advantage over an older town where the ground is bare. What is frequently missing is the part that makes it work: sheets overlapped and taped, run up the perimeter wall and sealed to it, and held down at the edges. A membrane lying loose on the ground with open joints stops very little, and because it is clearly there, everybody who has looked has assumed the ground was dealt with. Checking how it was terminated is a five-minute job and it changes the scope.
The services that were run through it because it was convenient
A crawl under one section of a house is where the trades put whatever was awkward: a heat run to the room above, a water line to a rear bathroom, sometimes a sump. That is why this space matters more than its size suggests, and it is the reason the freeze risk here is real rather than theoretical. Insulating the floor above rather than the perimeter leaves every one of those on the cold side, which is the opposite of what the house needs.
The hatch decides what covering is even possible
Where a Beaumont crawl space is accessible the foam takes a thermal barrier or an ignition barrier over it, and on these houses the practical question is not which one but how it gets in there. The access on a young house is almost always a small hatch cut into the floor of a finished room, a closet or a laundry, sized for somebody to look rather than to carry. Sheet material cannot go through most of them. That constrains the covering to what can be applied in place rather than what would be chosen on a drawing, and it is the reason this gets settled on the visit with a tape in hand rather than assumed from a specification.

Crawl Space Spray Foam Insulation Beaumont: Common Questions
Why is only one room cold? That is the usual pattern here, and it is normally the room over the crawl.
Is plastic already on the ground enough? There usually is. Whether it was lapped and sealed to the wall is the question that matters.
Should we insulate the floor above instead? No. That leaves the pipes and ducts on the cold side, which is the wrong side.
