We supply new extinguishers alongside service work, in the same brands we service. Tell us the hazard and the room and we size the unit and the rating for it, then quote. There is no checkout, because the right unit depends on what is in the space.

ScopePortable extinguishers only. Our Texas license is Type B, which covers portables, so we do not service sprinkler systems, fire pumps, or fixed and pre-engineered kitchen suppression.
