Buyers typically pay $150-$2,200 per EH fire damper depending on size, motorization, and installation complexity; primary cost drivers are damper size, UL listing, actuator type, and labor. This article lists EH fire damper price ranges, installation assumptions, and ways to lower the final cost.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| EH Fire Damper Unit | $150 | $450 | $1,200 | Assumptions: steel blade, 12×12 to 36×36 in, non-motorized |
| Motorized EH Damper | $350 | $900 | $2,200 | Assumptions: spring return, 24–120V actuator |
| Installed (per unit) | $300 | $750 | $1,500 | Assumptions: one-hour access, 1–3 technicians |
Typical Total Price For An EH Fire Damper Installation
Most projects with a single EH fire damper range from $450 to $1,650 total installed, including materials and labor.
Typical totals: Low $300 (small in-stock unit, basic labor), Average $900 (mid-size damper, motor or smoke detector, 1–2 hours install), High $1,800+ (large sizes, custom frame, restrictive access, firestopping upgrades). Assumptions: urban U.S., standard commercial drywall/duct, UL555 listing required.
Line-Item Pricing: Materials, Labor, Equipment, and Permits
Breaking a quote into concrete parts helps compare contractors and find savings.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $150 | $450 | $1,200 | Damper unit, frame, gaskets |
| Labor | $100 | $300 | $900 | (1–4 hours) |
| Equipment | $25 | $75 | $300 | Lifts, scaffolding, hot work tools |
| Permits | $0 | $25 | $150 | Local inspection or permit fees |
| Delivery/Disposal | $0 | $25 | $100 | Small freight or jobsite disposal |
How Size, Actuator Type, and UL Rating Change the Quote
Size and actuator are the single largest cost multipliers for EH dampers.
Examples of numeric thresholds: up to 24×24 in typically fits stock ranges ($150-$450 unit); 24×24 to 36×36 in often requires special order (+25%-75%); sizes over 48 in may require custom fabrication (+100%+). Actuator thresholds: manual/spring ($0-$150 extra), electric 24V/120V ($200-$600), fail-safe/motorized smoke control ($500-$1,200+). UL listing level: basic UL555 ($0-$100), fire-and-smoke combined ($150-$600 extra).
Site Conditions That Drive Installation Time and Cost
Restricted access, ceiling type, and fireproofing needs add labor hours rapidly.
Examples: open ceiling ease—30–60 minutes per damper; working above finished ceiling or in chase—2–6 hours per damper; overhead hoisting/scaffold required adds $150-$600. If contractors must cut structural members or perform hot work, expect additional $300-$1,000 for firestop and inspections.
Ways To Reduce EH Fire Damper Price Without Sacrificing Code Compliance
Buy the simplest UL-listed damper that meets the project’s code and avoid unnecessary upgrades.
- Order stock sizes (≤24×24 in) to lower unit cost and lead time.
- Choose manual or spring-actuated unless motorized is required by design.
- Bundle multiple dampers for a contractor discount and reduced mobilization fees.
- Prepare access and remove obstructions before crew arrival to reduce labor hours.
- Accept contractor-provided standard warranty instead of extended plans to save upfront costs.
Regional Price Differences: Urban Versus Rural and Climate Zones
Location affects labor rates and lead times; expect 10%-40% regional variance.
Typical deltas: Urban Northeast/West Coast +15%-40% over national average; Midwest/South central -5%-15%; Rural areas may have higher delivery fees or contractor minimums adding $50-$300 per job. Assumptions: quoted average above reflects mixed urban/suburban markets.
Three Real-World Quote Examples With Specs and Totals
Sample bids show how spec choices change final pricing.
| Example | Spec | Labor Hours | Unit Price | Total Installed |
|---|---|---|---|---|
| Budget Retail | 12×12 EH, spring, stock | 0.5 (1 tech) | $150 | $300 |
| Standard Office | 24×24 EH, 120V actuator, smoke link | 1.5 (2 techs) | $650 | $1,050 |
| Hospital Smoke Control | 36×36 EH, motorized fail-safe, UL fire+smoke | 4 (crew + scaffolding) | $1,500 | $2,400 |
Typical Add-Ons, Permits, and Inspection Fees That Appear on Quotes
Expect line items for firestopping, testing, and permit/inspection fees to affect the final invoice.
Common extras: third-party damper testing $75-$250 per damper, firestopping patch $50-$300, permit/inspection $0-$150, rush delivery $50-$300, diagnostic or access testing $75-$150. Including these in initial estimates avoids surprises.
