From single-family homes to commercial developments, we deliver precision glass installation on schedule and on budget for builders across the DMV. One subcontractor for every glass product your project needs.
Your Glass Subcontractor
New construction glass requires precision coordination between multiple trades, tight scheduling windows, and zero tolerance for products that fail inspection. Expert Glass Repair has been the trusted glass subcontractor for builders across the DMV for over 20 years -- handling everything from standard window packages to complex curtain wall systems under one contract.
We integrate with your construction schedule from preconstruction through punch list. Our team reviews plans, prepares takeoffs, manages lead times, verifies rough openings, and installs every piece of glass on the exact date your project requires. When you work with us, glass is never the trade that holds up your timeline.
Whether you are building a single custom home, a 100-unit townhouse community, or a mixed-use commercial development, we bring the expertise, manpower, and reliability that builders depend on.
Established in 2004, we have partnered with hundreds of builders on thousands of new construction projects across DC, Virginia, and Maryland.
Every installation meets current IECC energy codes, safety glazing requirements, and local building code standards. We pass inspections on the first attempt.
All installations carry our 5-year workmanship warranty plus full manufacturer product warranties. We stand behind every piece of glass we install.

Builder Timeline
We align our work with your construction phases so glass installation never holds up your timeline. Five coordinated phases from preconstruction through punch list.
We review architectural drawings, prepare material takeoffs, identify long-lead items, and submit shop drawings for approval.
We visit the site to verify rough openings against specifications before glass is ordered.
Windows, storefronts, curtain walls, and exterior glazing installed once framing is complete and weather barriers are in place.
Glass partitions, conference room walls, and interior door systems installed once drywall, flooring, and mechanical rough-ins are complete.
Frameless shower enclosures, glass railings, mirrors, and specialty glass installed during the finish phase.
Collaboration
We tailor our process to the way you work -- whether you need specification support, schedule integration, or cost optimization across a multi-project portfolio.
We collaborate with architects from the design phase to ensure glass specifications are buildable, code-compliant, and within budget.
We integrate seamlessly with your construction schedule. Our project coordinators track milestones, manage lead times, and schedule installation crews to.
We help developers control glass costs while meeting performance and aesthetic requirements.
Code Compliance
Every glass product we install is selected to meet or exceed the energy performance requirements of the applicable building code. We help builders navigate the requirements so glass is never the reason you fail an inspection.
The DMV falls within IECC Climate Zone 4A, which sets specific U-factor, Solar Heat Gain Coefficient (SHGC), and air infiltration limits for fenestration products. DC has additional green building requirements, and Virginia and Maryland each adopt their own versions of the IECC with local amendments. We stay current on all three jurisdictions.

Design Consultation
Choosing the right glass for each application is critical. We help builders and architects select products that balance performance, aesthetics, code compliance, and budget.
Standard for all new construction. Dual-pane with low-emissivity coating and argon gas fill. Meets IECC 2021 energy code requirements.

Project Coordination
Glass lead times are one of the most common causes of construction delays. Standard windows require 2 to 3 weeks from order to delivery. Tempered custom glass needs 3 to 4 weeks. Specialty products like curtain wall systems, oversized panels, and custom shapes can require 6 to 8 weeks or more.
We eliminate lead-time surprises by front-loading the ordering process during preconstruction. Our project coordinators create a material procurement schedule that maps every glass product to the construction phase when it is needed, then work backward to determine the latest possible order date.
For production builders running multiple units, we maintain rolling inventory of standard window sizes and deliver in batches timed to your framing schedule. For custom projects, we track every fabrication milestone and provide weekly status updates so there are no surprises.
