What Skills Should a Commercial Glazier Have? Vetting Guide

A qualified commercial glazier carries seven core skills: shop drawing reading, structural anchor installation, sealant joint craft, NOA submittal navigation, field quality control, safety culture, and schedule discipline. Here is the framework to vet whether the glazier you are hiring actually has them.

Shop drawing literacy

Commercial glazing scope is defined by shop drawings: elevations, sections at head/sill/jamb, anchor details, hardware schedule, glass type call-outs, sealant joint sections. A glazier who cannot read or produce competent shop drawings cannot reliably ship the scope. Ask for a sample shop drawing set from a recent similar project.

Structural anchor installation

Anchor performance is the single biggest determinant of long-term envelope integrity. Anchor type depends on substrate (concrete, CMU, steel), wind pressure, and assembly. Glaziers without trained anchor-installation crews leak, lose hardware, and fail in storms. Ask how the foreman trains anchor installation and what QC checks happen before sealant covers the anchor.

Sealant joint craft

Structural sealant (Dow Corning 995, Sika SikaSil WS-305) requires Dow- or Sika-approved applicator certification. Weatherseal sealants require proper substrate prep, primer where specified, and tooled joint application. ACG is an approved applicator for both Dow Corning and Sika commercial sealant lines.

NOA submittal navigation

In HVHZ markets (Miami-Dade, Broward), every assembly requires a current Miami-Dade NOA or equivalent. A glazier without NOA submittal experience loses 2-3 weeks of schedule on every HVHZ project. Verify three Miami-Dade NOAs from completed projects in the last 24 months.

Field QC and punch discipline

Punch list closeout at substantial completion is where less-disciplined glaziers fail. ACG runs a 5-day punch turnaround standard — the GC and owner notice. Field QC starts during install, not after.

Safety culture

OSHA-10 and OSHA-30 minimums. Written fall-protection program. Documented incident-free record. Zero OSHA recordables since 2021 at ACG. Documented training records available.

Schedule discipline

Weekly Friday look-ahead. 48-hour bid response. 24-hour RFI response. Submittal package complete on first submission. The glazier who keeps these standards is the one who finishes when promised.

Frequently asked questions

How do I verify a glazier has these skills?

Ask for shop drawing samples. Verify three NOAs from recent projects. Call three GC references from the last 12 months. Ask the references one question: would you hire this glazier again?

What credential does a commercial glazier need in Florida?

Florida CGC (Certified General Contractor) or CGB (Certified Building Contractor) for full commercial scope. CC-C (Certified Glazing Contractor) for dedicated glazing-only scope. Verify the license at MyFloridaLicense.com.

Does ACG hire union-certified or non-union glaziers?

Non-union. W-2 employees. ACG pays Davis-Bacon prevailing wages on federal-funded projects when contracted. Field crews trained on Kawneer, YKK AP, Tubelite, ESWindows, and Euro-Wall systems.
