Duct Takeoff Services
Gain Absolute Clarity on Sheet Metal Fabrication and Installation Costs Before You Bid.
Bidding on mechanical and HVAC systems is exceptionally cost-sensitive; a single miscalculated gauge conversion or an overlooked run of high-pressure fittings can instantly wipe out your profit margins. Professional duct takeoff services convert complex sheet metal drawings into exact material weight (pounds), fabrication labor hours, and precise fitting counts, eliminating the guesswork from your pipeline. We provide industry-leading, data-driven sheet metal duct estimating engineered to protect your bottom line.
Whether you need our standard 16-24 hours-hour turnaround or a lightning-fast 5 to 16 hour emergency rush option, we deliver precise material quantities and labor costs based on specific SMACNA standards.
Backed by a 92% bid-win ratio and transparent, flat-fee pricing starting from $200, our solutions our solutions empower you to instantly scale your preconstruction capacity your preconstruction capacity while reducing your in-house estimating overhead by up to 60%. We proudly support HVAC duct fabricators, sheet metal contractors, and mechanical engineers with a nationwide reach across all 50 U.S. states, explicitly highlighting heavy-volume construction markets like New York (NY), California (CA), Florida (FL), Nevada (NV), and Texas (TX).
Stop Bleeding Margin on Linear Footage Shortcuts and Missed Fittings
Bleeding margins often start at the conceptual phase when estimators try to price sheet metal by simple linear footage rather than material weight and fabrication complexity. Here is how our professional estimating team eliminates early-stage risks and protects your capital:
The Bidding Headache
Linear Footage Shortcuts
Pricing ductwork by the foot drastically under-prices a duct run, as sheet metal is fabricated and priced by weight, not length.
Blending Straight Duct & Fittings
Pricing fittings at the same rate as straight duct ruins your bid; a fitting-heavy layout will be noticeably under-bid without separating the labor costs.
Missing Hangers and Accessories
Forgetting to quantify trapeze hangers, tie-rods, stiffeners, and volume dampers forces you to pay for essential installation components out of pocket.
High Preconstruction Overhead
Paying full-time estimators to manually measure thousands of feet of spiral and rectangular duct drains your cash flow during seasonal dry spells.
The Turner Solution
Weight-Based Calculations
We calculate the straight duct's surface area and convert it to exact weight (pounds) using standard gauge-to-weight conversions (e.g., 22-gauge galvanized steel at 1.156 lb/SF).
Fitting-Specific Labor Rates
We count elbows, transitions, tees, and offsets separately, pricing them at a higher labor rate per pound to account for the increased fabrication and installation time required.
Comprehensive Accessory Extraction
We meticulously extract every required hanger based on duct run length and code-required spacing, alongside dampers, diffusers, and grilles.
Scalable Flat-Fee Support
Our pay-per-project model removes fixed estimating overhead, delivering ductwork takeoff data exactly when you need it.
