Tariffs complicate growth and broader market landscape for leading glaziers

The leading glaziers serving the North American market reported higher overall sales and healthy capital investment as well as expansion in 2024. But the larger picture remains complex for companies as 2025 unfolds, as the industry weathers cascading challenges related to tariffs, including ongoing cost-rises due to inflation and supply chain disruptions, as well as the number one barrier to growth: the shortage of unskilled labor.
This year’s Top 50 Glaziers posted total sales of $4.39 billion in 2024—up from 2023’s $4.17—surpassing the highest total gross sales in recent years in 2017 at $4.3 billion.
More so than in previous years, it feels important to state that this introduction is being written in the middle of May during a time of economic turbulence. As trade relationships shift, some in the industry report uncertainty about the status of larger projects and see a longer-term potential for slowdown.
For Top 50 Glazier Vos Glas, the start of 2025 has been a recovery from the economic turbulence in the last few years. “Prior to tariffs, it had felt like the first year in many that there weren’t outside headwinds that would be affecting our business, be it material price increases, lead times, COVID or looming economic slowdown,” says Josh Turner, president, Vos Glas. “Like most, the uncertainty surrounding tariffs has the potential to affect our pricing and overall building costs. Our concern is that some projects in development become over budget and are put on hold.”
The beginning of the year also saw a major consolidation, as long-time Top 50 Glazier Permasteelisa acquired the assets of Benson, another longtime member of this industry ranking. “The expansion of our North American footprint is a crucial component of our long-term growth strategy and this acquisition is an exciting milestone on our path toward achieving it,” says Liam Cummins, CEO, Permasteelisa Group, in a press release.
Glass Magazine has been facilitating ongoing conversations regarding Divisions 8 and 10, and questions in this year’s survey reflect that. Leading company perspectives remain mixed, though many are interested in glaziers working on interior glass and glazing systems. “Division 10 has historically been a part of our business but over the last few years has slowly eroded,” says Brock West, president and CEO of Top 50 Glazier Glass Systems Inc. “We are committed to regaining that business within Division 8 in 2025 and beyond.”

Higher competition for projects

Backlog of 1 year to 18 months
The growth—both for leading glaziers and the North American contract glazing market—is again a mixed picture. Sales growth has slowed for some companies, but competition has not.
Sales slow, competition increases and profits remain static
Top 50 Glaziers survey respondents reported slower year-over-year growth; 59% said their sales had increased year over year, compared to 64% last year. More significantly, no companies reported lower competition year over year, and 53% said they experienced higher competition in 2024, a nine-point increase from last year’s report. This follows a similar pattern to Glass Magazine’s Top Glass Fabricators report, published in April, in which only 32% of respondents reported year-over-year growth.
Related to these changing indicators, respondents reported that profit margins were fairly static, while bid levels trend slightly down. Company backlog also didn’t show a dramatic amount of movement, though slightly more companies report having a backlog of six months or more compared to last year.
Regional growth swings between Northeast and Southern regions
Regional growth swung back to the Northeast in 2024, according to Top 50 respondents, upsetting last year’s predictions, which pointed instead to the Southeast. Companies identifying it as a region of growth for 2024 and 2025 attribute growth to government projects, health care and an interest in school security. “The Northeast has a well-supported economy fueled by outside factors of higher education, travel/tourism, four seasons and good employment,” say reps of Top 50 Glazier Sunrise Erectors Inc. “Whilst the economy has slowed and competition increased, there has still been market capture.”
Despite this, respondents still point to the Southeast again as the most likely to see growth in the coming year. A plurality of respondents say population growth is spurring the growth of projects in this area. A significant number of respondents also named the Southwest as a growth area, attributing the expansion to population growth and migration. “Population growth in Nevada and Arizona is another key contributor, particularly in Las Vegas and Phoenix,” says Andrew Phipps, director of of marketing for Top 50 Glazier Giroux. “With the demand for infrastructure, commercial properties have surged.”
Ten glazier respondents said their companies also recently added new locations, including Harmon, which opened a new manufacturing facility in Dallas, Texas, at the start of the year. The project represented an expansion of an existing facility to add new capacity.

In addition to asking glaziers about project delivery methods and the type of services they provide, we asked about an issue we know has been a topic of discussion: Division 8 and 10 work. About a quarter of fabricator respondents for the Top Glass Fabricators report noted Division 10 work as a 2024 design trend.
The Top 50 Glaziers survey respondents said that, on average, interior glass and glazing systems comprise about 23% of their work. About 7% said that interior glass comprises 50%-100% of their commercial work. Several responding companies do not work in the Division 10 segment at all.
Plurality of glaziers question Division 10 segment
Companies had a range of viewpoints regarding the separation of Divisions 8 and 10. Representatives of Top 50 Glazier Vetro, a Division of Roschmann Group, said that Division 10 tends to include more specialty or unique glazing scopes, such as custom cast glass light boxes. “All predetermined product assemblies should be listed in Division 10, making them proprietary to a certain extent, providing transparency about cost, functionality and warranty.”
Though not all agreed, several companies voiced support for glaziers installing glass, regardless of the division. “Glass and glazing subcontractors are already specialized in handling interior and exterior glass systems with the precision, engineering and installation expertise required. Keeping partitions and demountable walls under Division 8 makes the process smoother for everyone—owners, architects and general contractors—because it consolidates responsibility with a trade that understands the nuances of glass products,” say representatives of a Top 50 Glazier survey respondent.
“Division 10 is a loophole to pay less for labor compared to glaziers’ prevailing wage rates,” says Rush Golden, president, Golden Glass.
Beyond Divisions 8 and 10, survey respondents did not report much change in the market segments that comprise their commercial, institutional and other project types, except for the educational segment, which increased five points from 2023 to 2024. According to a new survey question, 74% of responding glazing firms provide contract glazing for school construction.

Labor + Headwinds
81%
Tariffs will be a major headwind
52%
Recruitment is most difficult labor challenge
44%
Glaziers and field labor positions were difficult to fill
Given that Glass Magazine received Top 50 survey responses in spring of 2025, tariffs were ranked as the number one headwind moving further into 2025, followed by fears of economic slowdown and inflation. As during other moments of economic uncertainty, companies worried about increased costs, project pauses and long-term financial stability.
“We see market instability as a foreseeable challenge in 2025, with a trickle-down effect possibly lasting into 2026,” says Ricky Urbach, chief operation officer, A-1 Glass.
Glaziers say lack of skilled labor can be costly
Finding, retaining and training employees remains a perennial issue for companies. Recruitment remained a top challenge this year, with 52% of respondents marking it as their top labor challenge. A plurality of respondents say that the limited labor pool results in a workforce characterized by high turnover and lack of relevant skills, which in turn limits the company’s growth. This mitigation of growth can show up in several ways—from costly rework because of an unskilled field worker to competitive wages and investment in training that can further strain the company’s budget.
“With fewer skilled workers available, projects take longer to complete,” say representatives of Top 50 Glazier Eastern Glass & Aluminum. “This delay affects everything—from the initial planning stage to the final handover. And the labor shortage limits the number of projects a company can take on at once. Even if demand is high, a company may need to turn down potential projects due to insufficient workforce. The company’s plans to diversify or grow into new sectors might stall, preventing long-term growth.”
Top 50 Glazier Momentum’s CEO Omar Maalouf says that a lack of skilled labor can also result in the company’s “inability to move into other markets and expand [their] footprint across the southern U.S.”
Companies provide diverse employee benefitsCompanies continue to offer a range of employee benefits, including but not limited to health care, additional days off, financial management courses and leadership development opportunities. A plurality of companies offer access to addiction-recovery programs and mental health and/or counseling.
