Glazing Contractor
Overhead Rate.

Glazing subcontractors carry premium overhead driven by engineering coordination, specialized equipment for curtain wall installation, and the precision quality control that glass and glazing systems require.

Overhead Benchmarks — Glazing Contractors — By Revenue Band

What Normal Looks Like
At Your Revenue Level.

These benchmarks are drawn from SPM's work with commercial glazing contractors and industry data. Calculate your actual overhead rate — total G&A expenses divided by total revenue for the trailing 12 months — and compare to your revenue band below.

How to use this data: If you're above the top of the range, specific categories need review. If you're below the bottom, you may be underinvesting in systems and staff. Use the benchmark as a target range, not a single number.

Trade note for Glazing Contractors: Glazing contractors consistently show premium overhead rates and premium gross margins compared to other specialty trades — reflecting the engineering expertise, precision quality control, and specialized equipment required for curtain wall and storefront systems. A $3M glazing contractor with 25%+ gross margin and 14–18% overhead is performing well relative to trade benchmarks.

Why Overhead Rate Gets Off Track

Three Reasons Your
Overhead Is Drifting.

01

Shop Drawing and Engineering Labor Gets Buried

Curtain wall and storefront shop drawing preparation, engineering review, and submittal coordination are direct job costs for the specific glazing scopes being engineered. When this labor gets coded to overhead, installation jobs look less profitable and overhead is overstated.

02

Specialized Equipment Overhead Is Underallocated

Vacuum lifters, curtain wall dollies, and specialized glazing equipment used on specific jobs should be allocated to those jobs via internal rates. When this equipment cost sits in overhead, large curtain wall jobs look more profitable than they are.

03

Quality Control and Warranty Overhead

Glazing quality control — air and water infiltration testing, thermal performance verification — and warranty program administration create overhead that most glazing contractors undertrack and underprice in bids.

How SPM Manages It

Overhead Rate as a
Managed Number.

Engineering Cost to Jobs

Shop drawing preparation, engineering review, and submittal coordination for specific glazing projects are coded to those jobs in ControlQore — not to overhead. Engineering labor that directly supports a specific curtain wall or storefront installation belongs in that job's direct cost.

Specialized Equipment Allocation

Vacuum lifters, curtain wall dollies, and specialized glazing equipment costs are allocated to specific jobs in ControlQore via internal rates. Large curtain wall jobs with high equipment utilization reflect their true equipment cost.

Quality Control Program Cost Tracking

Air and water infiltration testing, thermal performance verification, and warranty program administration costs are tracked as a dedicated overhead category — supporting accurate QC cost pricing in glazing bids and revealing the true cost of maintaining premium quality standards.

Common Questions

Straight Answers.

How do I calculate my overhead rate?
Add up every expense that isn't a direct job cost for the trailing 12 months — office staff, rent, insurance, equipment payments not allocated to jobs, vehicles, software, marketing. Divide by total revenue for the same period. That percentage is your overhead rate. Compare it to the benchmark for your revenue band above.
Does SPM serve glazing contractors at all revenue levels?
SPM's direct engagement covers $1M–$12M in revenue. The benchmark data on this page covers the full revenue spectrum for reference. For contractors above $12M, SPM can make the right introduction to firms that specialize at larger scale.
