What General Contractors Actually Look For in a Commercial Glazier (Beyond Price)

Inside view from a commercial glazier on what GCs really evaluate when selecting glazing subcontractors for Florida commercial projects. Response time, submittal completeness, and field performance.

GCs do not pick the lowest bidder. We win bids at 8-12% above the low bid every week. Here is what GCs actually evaluate when they pick a commercial glazier — and what most glaziers get wrong.

Response time on the initial bid

GCs send drawings to 4-7 glaziers. The first 2 to respond with complete bids set the floor. The next 2 might still be looked at. The last 2-3 are usually ignored. We respond to commercial bid requests inside 48 hours. The Florida commercial glazier average is 7-15 days. That speed alone moves us into the 'serious contender' pile on every bid.

Submittal completeness on the first round

After award, the submittal package is the second selection criterion. Complete on first submission means shop drawings + product data + NOA/Product Approval documentation + structural calcs + sealant compatibility letters in one package. Incomplete first submissions cost the GC 2-3 weeks of schedule and prove the glazier is not field-ready.

Field crew quality and OSHA discipline

GCs walk the field daily. A glazing crew that wears proper PPE, hot-works permits when required, sets up safety per-section, and doesn't leave debris and cigarette butts is a crew the GC will hire again. The opposite gets debriefed at the post-project review and not invited to bid the next job.

Communication frequency and quality

We send weekly look-ahead schedules every Friday. We respond to RFIs inside 24 hours on commercial scopes. We don't go dark for 3-5 days. GCs notice. We've been added to bid lists specifically because of our communication frequency — we make their job easier.

Punch list responsiveness at substantial completion

Most glazing punch lists are sealant joints, gasket alignment, hardware adjustment, and minor glass scratches. Address them inside 5 business days. We have crews dedicated to punch turnaround. GCs who finish projects on schedule have glaziers who finish punch on schedule.

Warranty service after substantial completion

Year-one warranty calls happen. The question is whether the glazier shows up. We have a documented 5-day response on warranty service. Glaziers who ghost after substantial completion get exactly one project from each GC, then they're out.

Project-type specialty

Restaurant glaziers and hospital curtain wall glaziers are different specialties. School punched-opening glazier and luxury residential balcony rail glazier are different specialties. GCs notice when a glazier has done their specific project type 5+ times recently. Specialty matters.

Financial stability and bonding capacity

On commercial projects over $250K, GCs check bonding capacity. On projects over $1M, they verify it. On AIA G706 or sworn statement workflows, they verify lien waivers. A glazier who doesn't bond, doesn't carry $2M general liability, and doesn't have a CFO function gets cut from larger bid lists.
