What is a garage door?

What this means for your home project

1. Read the door label for positive and negative pressure ratings; request the test report if those ratings are missing. Source: Pacific Northwest National Laboratory, read 2026-11-06.
2. Ask the local building department whether hurricane or windborne-debris requirements apply to the home; retain the answer for the replacement specification. Source: Pacific Northwest National Laboratory, read 2026-11-06.
3. Request a written retrofit scope stating whether the reinforcement kit needs a professional spring-tension adjustment. Source: Pacific Northwest National Laboratory, read 2026-11-06.
4. List any observed binding, sticking or imbalance in the service request so the professional can address the door’s condition. Source: U.S. Consumer Product Safety Commission, read 2026-11-05.

How do I know if my garage door is properly balanced?

Garage door balance means the door stays where it stops: CPSC (read 2026-11-05) describes "any partially‐open position." A severely unbalanced door can fall unexpectedly, so balance is a safety issue rather than simply a question of opener convenience. (source)

“This means that the door will stay in place when stopped in any partially‐open position.” (source) “A severely unbalanced garage door could unexpectedly crash to the floor possibly striking someone under the open door.” (source)

Why isn’t my garage door opening or closing?

Garage doors that bind, stick or lose balance need attention to the door itself. CPSC (read 2026-11-05) says they "should be serviced by a professional." Describe the sticking or binding when requesting service; that symptom belongs in the repair scope. (source)

“If doors are not "balanced," or if they bind or stick, they should be serviced by a professional.” (source)

How do I know if my garage door is hurricane-rated?

Garage door wind resistance needs documentation. PNNL (read 2026-11-06) explains that the ANSI/DASMA 108 report records "the positive and negative pressure used in testing". Some door labels lack pressure ratings, so a missing rating on the label calls for the test report. (source)

“While some manufacturers provide wind speed and exposure ratings for their products (see Figure 3), labels on many garage doors do not include wind speed or wind pressure ratings.” (source) “While not required to be included on the product labeling, ANSI/DASMA 108 does require that the positive and negative pressure used in testing be recorded on the ANSI/DASMA 108 Test Report Form.” (source)

How do I determine my garage door’s wind load rating?

Garage door wind ratings must fit the home’s site. PNNL (read 2026-11-06) bases selection on "site design wind speed and exposure category." Confirm hurricane and windborne-debris conditions with the local building department, including whether local requirements exceed the cited residential code guidance. (source)

“Select garage doors that are pressure-rated for pressures associated with the site design wind speed and exposure category.” (source) “Confirm with the local building department if the house is in a hurricane-prone or windborne debris region and if local requirements exceed those of the IRC.” (source)

How is a garage door tested for wind load (ANSI/DASMA 108)?

Garage door wind testing is described in PNNL (read 2026-11-06)’s residential-code guidance under "Section R609.4 of the IRC". The guide names ASTM E 330 or ANSI/DASMA 108 testing and ANSI/DASMA 108 acceptance criteria; confirm the applicable local code before specifying a replacement. (source)

“Section R609.4 of the IRC requires garage doors to be tested in accordance with either ASTM E 330 or ANSI/DASMA 108 and to meet the acceptance criteria of ANSI/DASMA 108 (R609.4).” (source)

Why use a professional garage door dealer or installer?

Garage door retrofit work can extend beyond adding reinforcement. PNNL (read 2026-11-06) says a spring-tension adjustment "should be made by a professional installer." If a reinforcement kit requires that adjustment, request it explicitly in the written scope rather than treating the job as reinforcement alone. (source)

“After-market reinforcement kits may be available that can provide both vertical and horizontal reinforcement of the garage door.” (source) “If a reinforcement kit requires adjusting the spring tension, this adjustment should be made by a professional installer.” (source)
