Glass and Glazing Contractors

The 6,500 glass and glazing contractors in the US install glass panes in prepared openings and perform other types of glass work for buildings. Projects include new installations, additions, alterations, maintenance, and repairs. Smaller operators generally specialize in residential projects and emergency glass repair. Commercial projects include interior projects, such as the installation of decorative room dividers, and exterior projects, such as the replacement of storefront windows.

Specialized Labor Shortage

Glass and glazing contractors struggle to find qualified glaziers, who are workers that cut glass and perform the physical installation process.

Dependence On The Construction Industry

Demand for glass and glazing services is highly dependent on the health of the construction industry, which is cyclical and influenced by economic conditions.

Sep 8, 2026 - Construction Spending Remains Weak

• The total value of construction put in place fell 0.5% in July 2026 compared to June, according to the US Census Bureau. Spending for most types of nonresidential structures was weak in July. Office projects, which include data centers, saw the strongest growth with a 2.9% rise in July over June, followed by communication (+0.4%) and public safety (+0.1%). Educational and healthcare project spending declined by 0.4% and 0.5%, respectively, while amusement and recreation spending dropped by 0.3%. Commercial and lodging spending were both flat, and manufacturing spending was down 1%. Private residential construction spending was down 1.3% in July as single-family spending dropped 3.2% and multifamily rose 0.2%. The Associated General Contractors of America (AGC) said three segments are propping up the construction sector: data centers, power projects, and highways. However, the AGC suggests these three areas are under pressure from labor shortages, political headwinds, and a lapse in highway funding.
• The Wall Street Journal reports that investors are increasingly buying aging hotels that need renovations as property prices fall and new hotel construction slows. According to MSCI data cited by the Journal, US hotel sales rose 28% in the first half of 2026 compared with a year earlier. Lower borrowing costs, improving hotel revenue, and discounted property prices are helping attract buyers, while major hotel brands are becoming more aggressive about enforcing renovation requirements. Many owners have delayed upgrades because of debt burdens and limited cash. Increased hotel renovation activity could support demand for glass and glazing contractors as owners replace windows, doors, storefront systems, interior glass partitions, and other architectural glass features. New hotel room supply is growing just 0.5% this year, well below the historical average of 1.6%, making acquisitions and renovations more attractive than new development.
• Multifamily developer confidence weakened in the second quarter of 2026, according to the National Association of Home Builders’ (NAHB) latest Multifamily Market Survey. The Multifamily Production Index (MPI) dropped three points to 43 compared to the second quarter of 2025. The Multifamily Occupancy Index (MOI) decreased by 8 points to 74 over the same period. An MPI or MOI reading of 50 or more indicates that multifamily production or occupancy, respectively, is growing. Multifamily developers’ headwinds include volatility in building materials costs, high interest rates, and regulatory difficulties. While the NAHB expects the recently enacted 21st Century ROAD to Housing Act to help alleviate some of the building industry's challenges, the law's policies will take time to implement.
• US construction spending is forecast to decline just over 1% in 2026 after remaining flat in 2025, according to FMI's third-quarter 2026 North American Engineering and Construction Outlook. Single-family spending is projected to fall 4% as mortgage rates above 6.5%, weak builder sentiment, and incentives pressure home prices, while multifamily slips 1% before growth resumes in 2027. Among nonresidential buildings, office spending rises 2%, supported by a 21% surge in data center construction, while amusement and recreation grows 2%. Lodging falls 9%, commercial declines 5%, educational drops 1%, public safety falls 4%, and health care is essentially flat. Manufacturing is the largest drag, plunging 17% as semiconductor and battery megaprojects move beyond their heavy-spending phases. Residential improvements remain a bright spot, rising 5% as homeowners tap equity for renovations.
