Rolling Fire Door Repair & Testing in Chattanooga, TN
For rolling fire door repair in Chattanooga, TN, call (385) 325-7138 about a rated rolling assembly, a door that released unexpectedly, or an inspection and testing need. A rolling fire door is a listed coiling assembly designed to close an opening in a fire-rated wall automatically when a fire is detected. Repairing one is not the same job as repairing an ordinary roll-up.
Call to describe the problem—if the door is stuck open or the dock is down, say so first.

A fire door came down. What now?
If an alarm, smoke, fire, or an immediate threat is present, follow the facility’s emergency plan and contact emergency services rather than wait for a repair call. For the repair request, say which opening released, when it happened, and whether the building is operating normally.
Then leave it alone. Do not reset it, do not try to roll it back up, and do not remove or re-link anything. An unexpected release does not establish that the assembly is functioning correctly, and putting it back is a task with a documented procedure that varies by product. Getting it wrong can leave an opening that looks protected and is not.
Keep people clear of the affected equipment. Do not force it or keep cycling it. Follow your facility's established process for taking the affected bay or opening out of use.
One more thing worth saying plainly: a released fire door can affect an opening people were using. Whether that changes your egress, your fire watch, or your operations is a call for your safety and fire-protection people and your authority having jurisdiction — not something a repair page can decide for you.
Call and say which opening released and when.
Is it actually a fire-rated assembly?
Steel construction does not make a door a fire door. A rated assembly is one that was listed and labeled for the purpose and installed to match that listing.
Signs you are looking at one, from records you already have:
- A label on the curtain, guide, or hood identifying the listing and rating
- Drawings or a life-safety plan showing a rated wall at that opening
- Prior inspection or drop-test reports naming that door
- A release mechanism — a fusible link, a detector tie-in, or an alarm interface
If you have none of those and you are not sure, say so. "We think it might be a fire door" is a perfectly good thing to tell a provider, and it changes who should look at it.
| What you know | What it suggests | What to bring to the call |
|---|---|---|
| Labeled assembly, records on file | Rated rolling door | Door ID, rating, previous reports |
| A release device is fitted | Confirm the assembly’s listing and purpose | Which opening and what device, if you know |
| Fire wall shown on the plans at that opening | Check the specified protective assembly | The opening identifier |
| No label, no records, steel curtain | Unknown — assume nothing | Say it is unconfirmed |
| Tied into the fire alarm | Connected-system scope; confirm the door rating separately | Which alarm contractor maintains the system |
The rules, and which edition you are under
This is where the Chattanooga metro gets genuinely complicated, because the fire code edition depends on which side of the state line your building sits on.
Georgia side — Catoosa, Dade, Walker counties. Georgia's state minimum fire safety standards adopt the International Fire Code, 2024 edition, with Georgia modifications (Ga. Rule 120-3-3-.04). And they apply statewide: the rules state they have statewide application and do not require adoption by a municipality or county (Rule 120-3-3-.02). The building and occupancy determine which provisions apply.
Tennessee side — unincorporated Hamilton County. The county adopted the 2018 International Fire Code along with the rest of the 2018 I-codes, effective January 1, 2022 (Hamilton County Building Inspection).
City of Chattanooga. The city also enforces the 2018 International Fire Code (adopted codes).
So a company running one building in Chattanooga and one in Ringgold is under two fire code editions six years apart. Use the section and amendments belonging to the applicable edition. If a vendor quotes you a code section without saying which edition and which jurisdiction, that is worth a follow-up question.
NFPA 80 is the standard the fire codes lean on for fire doors and other opening protectives. Two things worth knowing about it:
- Its scope covers installation, inspection, testing, and maintenance of fire-door assemblies, including rolling steel ones.
- Georgia expressly lists NFPA 80, 2022 edition in Rule 120-3-3-.04(58). A newer published edition does not automatically replace that adoption.
- Ask for personnel with documented training and experience for the assembly. NFPA’s 2025 TIA 25-1 clarifies rolling-steel fire-door technician qualifications; it is not proof that Georgia adopted the 2025 text.
Which edition applies to your assembly is set by your jurisdiction's adoption, not by which edition is newest. Ask the fire code official. For Georgia, the listed edition is in the state fire rules; for Tennessee, ask the local fire authority for your address.
For your proposal, identify the door, the applicable edition, the inspection/testing scope, and the required records. The provider and fire code official confirm how those requirements apply to that assembly.
Inspection, drop testing, and records
A drop test checks the automatic-closing function under controlled conditions, including closure and the product-specific reset checks. It is different from a visual inspection and must follow the assembly’s instructions. Do not improvise a release or reset to prepare for service.
What a proper scope should name:
| Item | Why it matters | Ask |
|---|---|---|
| Which openings are in scope | The contract needs an explicit opening inventory | Which doors, by identifier? |
| Who performs the work | The assembly needs documented, relevant training and experience | Who does this, and what is their training? |
| What the test covers | A visual inspection and a drop test are different things | Is this inspection, testing, or both? |
| What happens on a failure | A door that fails needs correction, not just a note | Is corrective work included or separately authorized? |
| The written record | The fire code official may ask for it | What documentation do we receive, and in what form? |
| Frequency | Set by the adopted edition and your jurisdiction | Which edition and which authority is this schedule based on? |
Two warnings worth reading twice:
A general door maintenance visit does not automatically include fire door inspection and testing. If your PM contract says "inspect overhead doors," it may or may not cover your rated assemblies. Ask explicitly.
A test report is not blanket building approval. A provider can document inspection, testing, and completed repairs. Ask what any certificate covers, which doors it names, and which requirements it addresses; the authority having jurisdiction determines building-code compliance.
What happens when you call
- You call and describe the facility location and the observable problem.
- Your call may be shared with an independent commercial dock-and-door repair company.
- That provider confirms whether it can take the work and agrees scope, availability, pricing, scheduling, and terms with your facility before anything is authorized.
Not every company that repairs commercial doors takes rated work. That is normal, and it is one reason to say "fire door" early.
Example of what to say (wording, not a real job): "A rolling fire door at our Chattanooga facility released unexpectedly and we have the door identification in our records."
If you reach voicemail, leave the facility address, the door or dock number if known, what's wrong, and a callback number.
Call and say it is a rated assembly.
What to have ready — and what you do not need
Identification example: CornellCookson's AlarmGard tube motor is a product for compatible fire-door assemblies. Record the assembly and operator separately from existing documents; the operator name alone does not establish the opening's rating or required work.
Helpful if you have it: the door or opening identifier · the label or rating from your records · previous inspection or drop-test reports · what the release device is · which alarm system it ties into · your fire-safety contact.
Not needed: a photo of the label · a measurement · a diagnosis · anything that requires approaching a released or damaged assembly.
Nobody climbs, reaches into a hood, or works near a dropped curtain to gather information for a phone call.
What affects the cost of fire door work?
We can't quote your exact fire door work from a web page. The price depends on the assembly, whether it is inspection or repair, parts, and access. Here's what to clarify before you authorize work.
| Cost or decision driver | Why it changes the job | Question before you authorize |
|---|---|---|
| Inspection and testing versus corrective repair | Testing a door and fixing a failed one are separate scopes | Which is in this number, and how is the other handled? |
| The listed assembly and compatible parts | Ordinary coiling components may not be permitted on a listed assembly | What parts are specified, and do they preserve the listing? |
| Release system and alarm interface | Door work and alarm work may be two contractors | Who handles the door, the release, and the alarm tie-in? |
| Number of openings | The selected opening count changes the scope | Is this priced per door or per visit? |
| Access | Rated doors are often above racking or over traffic aisles | What access and downtime does this need? |
| Documentation | The record is part of the deliverable | What report do we get, and does it name each door? |
Ask which kind of number you are getting — call-out or diagnostic fee, starting price, scoped fixed price, estimate, or final quote.
Repair or replace. On a rated assembly the question is narrower than usual: can the repair be done with components that keep the listing intact? If an acceptable repair cannot be established with the manufacturer, listing requirements, and authority, discuss a compliant replacement. Ask the provider to say which it is and why.
Call and ask what the scope includes.
Local checks before you authorize work
| Where the building is | Fire code in force | Who to ask |
|---|---|---|
| Chattanooga city limits | 2018 International Fire Code | City fire authority and the Land Development Office |
| Unincorporated Hamilton County | 2018 International Fire Code, effective January 1, 2022 | Hamilton County Building Inspection and the local fire authority |
| Soddy-Daisy, East Ridge, Collegedale | Municipal adoption — confirm with the city | The city's building and fire offices |
| Any Georgia address — Ringgold, Rossville, Trenton | 2024 International Fire Code as the state minimum, applying statewide | County fire marshal and the Georgia state fire rules |
One Georgia rule specifically addresses exterior access in Group F and S buildings and warehouse-store Group M occupancies. Section 504.1.1 requires an access door for each 100 linear feet or major fraction of qualifying exterior wall facing the fire apparatus access road; for a continuous line of rolling dock doors, it uses 200 feet or fraction. It also addresses minimum opening size, ladder-free access, sprinkler-based rolling-door alternatives, and local approval. Ask the fire code official how it applies before changing those openings (Georgia fire rules).
For building or alteration scopes covered by Georgia’s plan-review rules, ask the building and fire offices who approves the plans and what construction-start or permit-expiry conditions apply. Do not assume an ordinary repair and a larger construction project have the same approval path.

Questions before you call
How do I know whether our rolling door is fire-rated?
Use what you already have: a label on the assembly, the life-safety drawings, prior inspection reports, and the specified release system. A release device or alarm connection alone does not establish a fire rating. Steel construction alone is not evidence. Nobody should climb or approach the door to check.
Can we roll a dropped fire door back up ourselves?
No. Resetting a rated assembly follows a product-specific procedure, and a door put back incorrectly can look protected while it is not. Leave it, take the opening out of use through your existing process, and get it assessed.
Does a general rolling-door service visit include drop testing?
Not automatically. Fire door inspection and testing is a separate scope requiring relevant training and experience. Ask explicitly whether your rated doors are named in the contract.
Which fire code edition applies on the Georgia side?
Georgia's state minimum fire safety standards adopt the 2024 International Fire Code with Georgia modifications, and those standards apply statewide without needing local adoption. Chattanooga and unincorporated Hamilton County list the 2018 edition, so building-by-building your answer can differ.
How often does a rolling fire door need testing?
DASMA’s published fire-door standard calls for inspection and testing at least annually (§16.2 of DASMA 204-2018). Ask the fire code official which adopted requirements govern your assembly, and have the proposal name the applicable edition, testing scope, interval, and records.
