Top 50 Glaziers 2023

As Top 50 Glaziers’ sales climb, companies struggle against worsening investment conditions

Top 50 Glaziers posted combined gross sales of $4.07 billion this year. While that impressive figure seems to suggest a return of some markets, glaziers say it does not mean  a return of labor, or a good sense of the future of building, largely due to how material price inflation and interest rates  have tempered investment.

“Many projects are shelved or progressing very slowly until there is a better understanding of where interest rates are heading,” says Thomas Cornellier, CEO, TSI Corp.

Interest rates compounded already-existing factors of getting material, in time, and keeping up with deadlines. “A big challenge in 2022 was the supply chain. Prices skyrocketed, lead times were the longest we’ve seen in a long time and construction didn’t slow down,” says Hemely Homez, project manager, Eastern Glass & Aluminum “It felt like it was us versus the world trying to get back on our feet.”

It goes without saying that labor, especially skilled labor, continues to be a significant challenge to growth. “Qualified and experienced glaziers are very hard to come by,” says Kevin T. Miner, vice president, Countryside Glass & Mirror.

The Top 50 Glaziers industry ranking is now in its 31st year. Companies are ranked according to gross sales in contract glazing for the North American market. If you think your company belongs on the list, please contact Norah Dick, senior editor, Glass Magazine. Beyond gross sales, Glass Magazine recognizes the excellent work of North American glaziers, nominated by their fabricator partners, who provided superior service in 2022.

Sales + Growth

Higher gross sales

Less competition for projects

Lower bid levels

Sales—and struggles—on the rise

Sales were higher in 2022, according to Top 50 survey respondents. Sixty-one percent of respondents said they had higher gross sales last year, as opposed to 54% in last year’s survey. While respondents also report higher profits in 2022, fewer respondents said competition levels and bid levels had increased this last year. This may be due to the project delays or pauses that respondents also described. 

“Many projects are shelved or progressing very slowly until there is a better understanding of where interest rates are heading,” says Thomas Cornellier, CEO, TSI Corp. “Right now, interest rates are creating issues in the banking community, which in turn is affecting financing. That ultimately can hurt the financial models for new builds, and since there is no rush, many developers are choosing to wait a year or so until they have a better understanding of the economic environment.”

Backlogs remain steady

  • 1 month or less 3%
  • Between 1 month and 6 months 2%
  • 7 months to 1 year 24%
  • 1 year to 18 months 34%
  • 18 months to 2 years 24%
  • 2 years or more 13%

Regional Sales Growth

Southeast, West show growth

A plurality of last year’s survey respondents predicted the Southeast would see growth in 2022.

That region did see growth, but was surpassed by the Western market, according to respondents. 

Nonetheless, responding glaziers again predict that the Southeast will see the most growth in the upcoming year. Several factors are affecting the expanding population in this region.

“This growth is due to a combination of great colleges and universities, great health care, and a large number of people migrating to this region for quality of life and cheaper standards of living,” says TSI Corp.’s Cornellier.

In the West, some respondents noted a rise in senior and low-income housing, and a strong health care market. 

Labor + Headwinds

Inflation will be a major headwind

Recruitment is most difficult labor challenge

Glaziers and field labor positions were difficult to fill


Respondents were asked to select all notable challenges anticipated for 2023. 

  • Inflation 75%
  • Economic slowdown 56%
  • Labor shortage 51%
  • Interest rates 44%
  • Supply chain 42%
  • Lead times 29%
  • Scheduling 20%
  • Growth in pre-contract work 9%
  • Difficulty getting building materials 5%
  • More complex curtain wall designs 5%

First inflation, now rising interest rates

Inflation replaced supply chain challenges as the major anticipated headwind for glaziers in 2023. Demonstrating the dramatic changes in the broader economic landscape, last year only 17% of respondents said an economic slowdown would be a challenge; this year, 56% of respondents did. Some respondents directly linked interest rates to the potential for a slowing economy. “Interest rates … will stall the economy if they keep increasing. This is one of the main contributing factors in my opinion for an economic downturn,” says Michael Carew, North American sales director, Carey Glass.

“We previously saw projects go on hold due to rising costs and material shortages, and now those same projects are still sitting because of rising interest rates and the concern of an economic slowdown,” says Egan Co.’s Ryan Woodruff .

“Inflation continues to drive up the cost for our products and services,” says Dan Frey, founder and president, The Glass Guru. Continued inflation, as well as increased interest rates, are also simply decreasing the amount of investment in building, glaziers say. “Banks aren’t taking on as much risk, larger projects are harder to get off the ground,” says Cassie Harker, CEO and COO, Pacific Glazing Contractors “There’s also this belief that construction material costs will decrease, so owners are delaying future builds.”

Supply chain delays remain

While supply chain woes may have lessened somewhat, they remain a significant issue to navigate for several companies. “A big challenge in 2022 was the supply chain,” says Hemely Homez, project manager, Eastern Glass & Aluminum. “Prices skyrocketed, lead times were the longest we’ve seen in a long time and construction didn’t slow down.” Eastern Glass worked to include both contractors and vendors in conversations in order to mitigate these issues.

Markets + Services

Project type by market


  • Office buildings 25%
  • Retail 9%
  • Hotels 5%


  • Education 19%
  • Healthcare 15%
  • Government 4%


  • Multifamily housing (high-rise apartments, condos) 4%
  • Transportation 3%
  • Residential (single-family homes) 3%
  • Other (market segments not covered above, e.g. entertainment centers, laboratory space) 3%   

Commercial building remains uncertain 

Institutional building saw an increase in 2022, according to Top 50 respondents. Commercial market growth remained relatively flat year over year, with office building construction falling by about 2 percentage points from the 2022 survey. 

The future of the hybrid workplace remains a major reason for uncertainty about office building construction. “We’ve seen the commercial office building sector slow down, with more companies having remote or hybrid workers,” says Ryan Woodruff, vice president, Egan Co.

“We’ve seen a fairly large increase in the health care sector as both hospitals and clinics are updating or creating new facilities.”

The economic slowdown has seen many tech-industry projects go on hold or be withdrawn altogether, causing the market to shift to other sectors of the industry.

Glaziers invest in trucks, pre-fab

In terms of production capabilities, more glaziers, 54%, reported fabricating curtain wall in-house this year. However, storage space and supply chain remain obstacles to pre-fabrication, as does having adequate staff. “Labor is at an all-time low. Pre-fab is at an all-time high. The two don’t mix,” says Andrew C. Wright, vice president of operations, Glass Solutions Inc.
Similarly, many glaziers report increasing their logistical operations. Trucks became companies’ primary capital acquisition this last year, likely due to continued transportation issues and  product transportation coming in-house. Fabrication equipment purchases remain a top capital acquisition as well, though slightly fewer glaziers report fabricating glass in-house this year. 

Glaziers encounter more protective glazing

The survey also asked about product trends. Seventy-two percent of responding glaziers say they encountered projects with protective glazing in 2022, a four-point year-over-year increase. Bird-friendly glass also saw a spike of almost 10 points year-over-year. Jumbo glass showed another expansion; 59% said they worked on projects with jumbo glass in last year’s report, leaping to 72% for this year’s report.

The List

Celebrating 31 years this year, Glass Magazine’s Top 50 Glaziers List remains the longest-running glass industry ranking.
