Excessive Door Gaps: Why Solving Them is Vital for Life Safety and Your Organization’s Future

Facility managers responsible for ensuring buildings meet fire door compliance know how critical it is to comply with codes from the National Fire Protection Association (NFPA). Non-compliance can lead to disasters that threaten the health and safety of those within their walls, causing injury and even loss of life. Claims and potential litigation as well as the expense of repairs, rebuilding, and loss of public trust can take a heavy toll on an organization’s health. 

Excessive door gaps have been a frequent cause of such violations. A door gap is defined as a space between a fire-rated door and its frame or the floor. Sometimes the door is lopsided, the wrong size or has sagged with age. Or new flooring may have increased the spacing at the bottom of the door. This can be hazardous if fire and smoke find their way through gaps, which is why fire inspectors started to check more thoroughly for them in the last few years. 

Probably no other group is more keenly focused on identifying and resolving excessive door gaps than the healthcare industry. Recent updates to code compliance from the Centers for Medicare & Medicaid Services (CMS) for NFPA 80 mean that fire door compliance violations at hospitals and other healthcare settings expose facilities to the risk of losing CMS funding, which can have a serious financial impact. Replacing fire doors in health care environments can also be an expensive call for alarm, typically costing thousands of dollars each for doors that do not meet tolerances. 

Fortunately, ASSA ABLOY offers an efficient and cost-saving option: excessive door gap sets that help hospitals and other facilities reduce gaps between a fire door and its frame or the floor, effectively preventing code violations from surfacing during fire inspection. Solutions include door extensions that reduce gaps between the door and its frame or between the door bottom and floor. 


Three types are available including bottom, top and perimeter extensions. Also known as fire door gap stops, door gap seals, fire-rated door extensions or door bottoms, these solutions are typically made from stainless steel, although Pemko also sells an aluminum door bottom shoe for easier modification in the field.

Benefits of Pemko Excessive Door Gap Sets:

  • Seal gaps to the clearances set by the NFPA 80

  • UL Certified for 90-minute fire doors

  • Bring fire doors up to code without replacing the entire door

  • Quick and easy resolution for fire inspection problems

  • Fast installation for nearly every door type

While the recent focus on periodic fire door inspections required in NFPA 80 created a greater need for ensuring fire doors are compliant in healthcare facilities, any facility required to have fire-rated doors will likely need excessive door gap solutions at some point during the life of the building. If you’re not sure about the clearances that have been set by NFPA 80, we can guide you through them as well as the solutions and products that can fix the problem.
