When a window breaks, your home or business becomes vulnerable. Weather, pests, and intruders can enter easily, and broken glass creates a major safety hazard. A professional window board-up service is the fastest and safest way to secure the area until new glass can be installed.
At B&L Labor Services, we provide emergency board-ups across the Triad and Triangle, including commercial storefronts, residential homes, rental properties, and retail locations. One of the most important techniques we use is the non-invasive board-up method, which protects the property without drilling into the structure.
This step-by-step guide explains how the method works, why it matters, and when you should request a board-up from a professional.
Why a Proper Board-Up Matters
People often try tape, plastic, or cardboard as a temporary patch. Those options may work for a few hours, but they do not secure the property.
A correct board-up:
• Prevents water damage, mold, and drafts
• Blocks unauthorized entry and vandalism
• Keeps out pests and animals
• Reduces liability and safety risks
• Protects the space until glass replacement
• Helps maintain insurance compliance
If your glass is shattered, cracked, or unstable, a professional board-up is always the safest choice.
What You Need for a Professional Board-Up
• ½" exterior plywood
• 2x4 boards for interior bracing
• Exterior screws
• Tape measure
• Drill
• Safety gloves
• Broom or shop vac
How to Board Up a Window Using the Non-Invasive Method
Best for storefronts, commercial glass panels, and any window frame you cannot screw into.
1. Remove loose glass
Wear gloves and remove any loose or dangling shards. Clean up the interior and exterior area for safety.
2. Measure the entire glass panel
Commercial glass often sits inside a larger connected system. Measure the full panel height and width to get accurate sizing.
3. Cut the plywood to fit
The plywood should cover the opening fully to protect against wind, rain, and debris.
4. Use the non-invasive pressure-brace method
This is what separates a professional board-up from a rushed one. You do not drill into the storefront frame, vinyl window frame, or decorative trim. Instead, the plywood is clamped securely using interior pressure bracing:
• Plywood goes on the outside
• 2x4 boards are placed on the inside
• Long screws connect the plywood to the interior 2x4s
• The pressure holds the board tight without touching the metal or vinyl frame
This method protects the structure, avoids costly repairs, and provides a strong temporary barrier.
5. Check for stability
The board should not shift, rattle, or flex. Tighten screws or adjust the 2x4 bracing if needed.
Common Mistakes to Avoid
• Drilling into the window frame or storefront metal
• Using thin or interior-grade plywood
• Leaving unstable or cracked glass behind
• Only securing the corners
• Forgetting the interior brace
• Using rusty or incorrect screws
How Much Does a Board-Up Cost?
Pricing varies depending on window size, height, materials, and urgency.
Residential board-ups: 150 to 275
Commercial/storefront board-ups: 450 to 900
B&L typical commercial rate: 500 to 700
Emergency, after-hours, or large glass panels may cost more due to labor and safety requirements.
Should You DIY or Call a Pro?
A simple board-up may look easy, but storefront glass systems require correct bracing and careful handling.
Hiring a professional ensures:
• No structural damage
• Proper pressure-bracing
• Correct materials
• Safe cleanup and removal
• Insurance-friendly documentation
If your window is broken, unstable, or part of a commercial storefront, call a board-up technician immediately.
