Capabilities
Commercial glass requires specialized knowledge of building codes, security standards, acoustic performance, and project coordination that residential glass companies simply do not have.
We know commercial building codes inside and out. Fire-rated glass assemblies, safety glazing requirements, wind load calculations, energy code compliance,
STC ratings, speech privacy performance, flanking sound control, and perimeter sealing details. We specify glass assemblies that deliver measurable acoustic performance for conference rooms, private offices, medical exam rooms, and any space where sound isolation matters.
Laminated security glass, bullet-resistant assemblies, blast-resistant glazing, forced-entry resistant windows, and security film applications. We understand the security glass ratings and specifications required by government contractors, financial institutions, and high-security commercial properties.
Multi-phase project coordination, material procurement scheduling, after-hours installation planning, building management liaison, and tenant communication. We manage commercial glass projects from specification through final inspection with professional project management at every step.
Evenings, weekends, overnight -- we work when your building is empty. Our commercial installation crews are experienced in working during off-hours with building management coordination, security access procedures, and noise restriction compliance.
Detailed documentation for insurance claims, warranty certificates, material specifications, code compliance records, and maintenance manuals. We provide the paper trail that commercial property managers and insurance carriers require for every glass installation and repair.
Our Process
From initial consultation through final walkthrough, our commercial process is designed to deliver quality glass work with zero disruption to your business.
We visit your property, assess the glass requirements, review building codes, measure all openings, and discuss scheduling constraints and budget parameters with your facilities team or property manager.
We provide a detailed proposal with glass specifications, energy and acoustic performance data, fire-rating compliance, project timeline, and pricing. You know exactly what you are getting before we begin.
We order all materials, coordinate fabrication timelines, arrange building access with property management, and schedule the installation during your preferred off-hours window.
Our crew installs the glass during off-hours, completes all cleanup before your business opens, coordinates any required inspections, and provides warranty documentation and maintenance guidance.

Glass Options
Commercial applications demand specific glass performance characteristics. Here are the key glass technologies available for your commercial project.
20 Min to 2 Hours
Glass assemblies rated for fire resistance from 20 minutes to 2 hours. Required by code in fire-rated walls, corridors, stairwells, and exit enclosures. We verify your specific fire-rating requirements with the building code official before specifying materials.
STC 28 to STC 45
Glass assemblies rated for sound transmission from STC 28 (basic) to STC 45 (confidential speech privacy). Laminated acoustic glass, double-pane assemblies with optimized air gaps, and specialized acoustic interlayers achieve the sound isolation your space requires.
UL 752 Rated
Laminated security glass, bullet-resistant glass rated to UL 752 standards, blast-resistant assemblies, and forced-entry resistant glazing. Multiple security levels from basic smash resistance to Level 8 bullet resistance for government and financial applications.
SHGC 0.20 to 0.40
Glass with coatings that block solar heat gain while maintaining visible light transmission. Reduces cooling costs for south and west-facing facades. Available in neutral, gray, bronze, and blue-green tints. Meets commercial energy code requirements.
PDLC Technology
Electrochromic or PDLC glass that switches from clear to opaque at the flip of a switch. Instant privacy for conference rooms, executive offices, and medical exam rooms. Eliminates the need for blinds and provides a high-tech aesthetic.
Starphire Ultra-Clear
Ultra-clear glass with minimal green tint for applications where crystal clarity and true color rendering are essential. Display cases, showrooms, restaurant glass, and architectural features where standard glass greenish tint is unacceptable.
Commercial Grade
Commercial glass work is fundamentally different from residential glass. The codes are stricter, the glass is heavier, the access is more complex, and the consequences of errors are more expensive. Here is what makes our commercial approach different.
Commercial glass panels can weigh hundreds of pounds. Large storefront panels, curtain wall units, and structural glass require specialized rigging, suction cup lifters, and multi-person crews trained in safe handling of heavy glass. This is not a job for a residential glass installer with a pickup truck.
Commercial building codes require fire-rated glass, safety glazing, wind load resistance, and energy performance that far exceed residential requirements. We specify every piece of commercial glass to meet the specific code requirements of the jurisdiction and building type.
Loading dock scheduling, freight elevator reservations, security clearance requirements, occupied tenant coordination, and after-hours building access protocols. Commercial glass projects require logistics management that residential projects simply do not have.
Every hour of disruption costs your business money. We plan installations to minimize downtime, work during off-hours when possible, and stage materials in advance so our crews can work efficiently and get out of your way quickly.
Client Reviews
“Expert Glass built out our entire K Street office with glass partitions, acoustic conference rooms, and switchable privacy glass. They worked entirely on weekends so we never lost a billable hour. The STC ratings are exactly what we specified. Our clients are impressed every time they walk in.”
George A.
K Street, DC
“A car jumped the curb and shattered our storefront glass at 3am. Expert Glass had us boarded up before opening and installed the replacement glass two days later. They provided all the documentation we needed for our insurance claim. We lost zero days of business. That is the kind of partner every retailer needs.”
Helen B.
Tysons, VA
“We needed HIPAA-compliant glass partitions for our medical practice. Expert Glass specified the right acoustic glass, installed it with proper seals, and coordinated the entire project around our patient schedule. The office looks modern and our patients have complete privacy. Highly recommend.”
Thomas F.
Bethesda, MD
Commercial buildings lose significant energy through their glazing. Upgrading to modern high-performance glass with Low-E coatings, insulated units, and solar control technology reduces HVAC costs, improves tenant comfort, and can help your building meet green building certification requirements.
We analyze your current glazing performance and recommend upgrades that deliver measurable ROI through energy savings. Ask us about glass upgrades that qualify for commercial energy efficiency incentives in Virginia, Maryland, and DC.
From emergency storefront repair to executive office glass buildouts, we deliver commercial glass solutions that meet your timeline, budget, and quality requirements. Get a free estimate today.
Compliance
Commercial glass is heavily regulated. We know the applicable codes and standards for every jurisdiction in the DMV and ensure every installation is fully compliant.
International Building Code Chapter 24 governs safety glazing in hazardous locations. We identify every location that requires tempered or laminated glass and specify the correct safety glazing for doors, sidelights, low windows, shower enclosures, and glass near walking surfaces.
UL 9, UL 10B, UL 10C, and NFPA 80 fire-rated glass and frame assemblies for fire-rated walls, corridors, and exit enclosures. We verify fire-rating requirements with the authority having jurisdiction and specify listed fire-rated assemblies that meet the exact rating required.
IECC commercial energy code requirements for glazing U-factor, Solar Heat Gain Coefficient (SHGC), and visible transmittance. Virginia, Maryland, and DC each adopt slightly different versions of the energy code. We track the requirements for each jurisdiction.
Americans with Disabilities Act requirements for door glass, entrance systems, and interior glazing that affect accessible routes. Door vision panels, automatic door operator compatibility, and hardware height requirements all factor into our commercial glass specifications.
ASCE 7 wind load requirements for exterior glazing including design wind speed, exposure category, importance factor, and internal pressure coefficients. High-rise buildings, coastal exposure, and wind tunnel effects all affect glass thickness and support requirements.
GSA and DoD blast resistance standards for government buildings and government contractor facilities in the DMV. ISC Security Design Criteria, UFC 4-010-01, and ASTM F1642 blast testing protocols. We specify the correct level of protection for your facility security requirements.
Emergency Response
When commercial glass breaks, every hour of exposure means lost revenue, security risk, and property damage. Our emergency response protects your business.
Broken storefronts, shattered office windows, vandalized entrance glass -- we board up any commercial opening the same day you call. Our crew arrives with exterior-grade materials and secures the opening to protect your inventory, equipment, and property until permanent glass is installed.
Standard tempered storefront glass is often available for next-day installation. We maintain relationships with commercial glass fabricators who prioritize our emergency orders. For standard sizes, we can have permanent glass installed within 24-48 hours of your call in many cases.
Commercial glass emergencies do not wait for business hours. We respond to emergency calls evenings, weekends, and holidays for board-up and securing services. Your property management team can call us at any hour and we will dispatch a crew to secure the opening.
When a storm hits the DMV and damages glass at multiple locations, we deploy multiple crews simultaneously. Property management companies and retail chains with several locations across the region can call us once and we coordinate the response for all affected properties.
We provide detailed damage documentation, photographs, material specifications, and cost breakdowns that commercial insurance carriers require for glass damage claims. Our documentation has been accepted by every major commercial insurance carrier in the DMV.
Beyond board-up, we provide temporary polycarbonate panels that allow visibility while maintaining security for retail storefronts. These temporary panels keep your business visible to foot traffic while you wait for permanent glass, minimizing the revenue impact of a broken storefront.
Building Types
From single-story retail to high-rise office towers, we provide commercial glass services for every building type in the DMV. Each property type has specific glass requirements, and we know them all.
Curtain wall glass replacement, window panel repair, lobby glass, conference room partitions, and interior glass features for office buildings from single-story to high-rise. We coordinate with building management for access, scheduling, and tenant communication. Multi-floor projects managed from start to finish.
Storefront glass installation and repair for retail businesses from small shops to anchor tenants. We understand that a broken storefront means lost revenue. Emergency board-up and expedited glass replacement keep your business open. Display case glass, entrance systems, and security glass available.
HIPAA-compliant acoustic glass partitions, privacy glass for exam rooms, clean-room glass, and safety glass for medical equipment areas. We understand healthcare facility requirements including infection control during installation, patient privacy standards, and medical office scheduling constraints.
Wine room glass enclosures, patio glass enclosures and windscreens, kitchen partition glass, host stand glass, and decorative glass features. We work around restaurant operating hours and install during closed periods. Glass that creates atmosphere while meeting commercial kitchen and food service codes.
Security glass for government contractor offices, blast-resistant assemblies, forced-entry resistant windows, SCIF-adjacent acoustic partitions, and fire-rated glass for institutional corridors. We have the security clearance awareness and code knowledge that government facility work requires in the DMV.
Condominium common area glass, apartment building lobby and entrance glass, property management maintenance programs, and multi-unit window replacement projects. We work with HOA boards, property management companies, and building management to coordinate access, scheduling, and budget across multi-unit properties.
Client Perspective
We earn repeat business from property managers, facility directors, and business owners across the DMV. Here is what they tell us matters most.
Commercial clients have schedules to keep. When we commit to a Tuesday evening installation, we are there Tuesday evening. When we promise a same-day board-up, we deliver same-day. Reliability is the foundation of every commercial relationship we maintain.
We do not guess about fire ratings, safety glazing requirements, or energy code compliance. We specify the correct glass the first time, which means your project passes inspection the first time. No delays, no reorders, no code violations to fix later.
We plan every project around your business operations. That means after-hours installation, pre-staged materials, efficient crews, and complete cleanup before your employees or customers arrive. Your business keeps running while we work.
Material specifications, warranty certificates, code compliance documentation, insurance claim documentation, and maintenance records. We provide the paper trail that commercial property management requires without being asked.
Emergency repair, planned replacement, new construction glass, partition buildouts, and ongoing maintenance. One vendor, one phone number, one relationship. Simplify your glass vendor management and get better service across the board.
Single storefront panel? We handle it. Twelve-floor office glass replacement? We handle that too. Our commercial glass capabilities scale from the smallest repair to the largest buildout in the DMV market.

Common Questions
Local Knowledge
We serve commercial properties in every major business district across the DMV. Our local knowledge of building management companies, access procedures, and permitting requirements in each area gets your project done faster.
The Dulles Corridor is home to some of the largest commercial glass projects in the region. High-rise office towers in Tysons, tech campus buildings in Reston, and retail centers along Route 7. We work with the major property management firms and know the access procedures for Tysons Tower, Capital One Center, Reston Town Center, and the Mosaic District.
K Street law firms, lobbying offices, and trade associations demand the highest quality glass partitions and conference room walls. Downtown DC office buildings have strict building management protocols. We navigate the loading dock schedules, freight elevator reservations, and after-hours security requirements that DC commercial glass work demands.
Government contractor offices dominate Crystal City and Pentagon City. Security glass requirements, SCIF-adjacent acoustic specifications, and the security awareness required for government-adjacent work are second nature to us. We have completed glass projects in buildings throughout the Crystal City underground complex.
Medical offices in Bethesda, retail along Wisconsin Avenue, the emerging mixed-use developments in Silver Spring, and corporate offices along the I-270 corridor. We serve medical practices that need HIPAA-compliant acoustic glass, restaurants opening in the vibrant downtown areas, and the growing number of coworking spaces in Montgomery County.
Ongoing Support
Property managers and facility directors trust us for ongoing glass maintenance that prevents problems before they become emergencies and keeps their buildings looking professional.
Regular inspection of all exterior and interior glass for seal failure, stress cracks, hardware wear, and weather seal deterioration. We identify problems early when they are inexpensive to fix rather than waiting for an emergency that costs more and disrupts your tenants.
Maintenance program clients get first priority for emergency response. When a storefront breaks at 2am, your call goes to the front of the line. We know your building, your glass specifications, and your access procedures, which means faster response and faster resolution.
We keep your building glass specifications on file so replacement glass can be ordered immediately without a site visit for measurement. When a pane breaks, we already know the size, type, coating, and tint. This can save days on the replacement timeline.
We provide annual glass condition reports that help you budget for future replacements. Knowing that twenty storefront panels will need replacement in the next two years allows you to plan the expense rather than being surprised by emergency capital expenditure requests.
One glass company for emergency repair, planned replacement, new construction, and ongoing maintenance. One phone number, one point of contact, one company that knows your building inside and out. Simplify your vendor management and get better service.
We coordinate directly with your tenants for interior glass work so your property management team does not have to. We schedule around tenant business hours, communicate timelines, and handle the logistics that make commercial glass projects run smoothly.
