First 60 Seconds: The Priority Checklist
Do not touch broken glass with bare hands — ever.
Put on shoes before entering the area.
Move children, pets, and barefoot family members out of the room.
If it was a break-in: do not enter the room — call 911 first.
If weather is entering: locate plastic sheeting or a tarp.
Step 1: Immediate Safety — Protect People First
The instinct when something breaks is to rush over and assess the damage. Resist it. Glass shards — especially from tempered safety glass — scatter further than you expect and can be nearly invisible on light-colored floors. The first minutes are about protecting everyone in the house, not evaluating the damage.
Shoes. Always Shoes.
Before you take a single step toward a broken window, put on shoes with a sturdy sole. Slippers and socks provide essentially no protection from glass shards. If you are in a room with broken glass and barefoot, freeze and look down carefully before moving. Glass fragments as small as 1mm can cause serious cuts.
Clear the Area of Kids and Pets
Children and pets are the highest-risk people in a glass emergency. Children do not instinctively avoid glass, and pets will walk through it without hesitation. Immediately close the door to the affected room if possible, or physically carry small children and pets away from the area. Do not let them back in until every fragment has been cleaned up — which should happen after the repair, not before.
Do Not Touch Broken Glass With Bare Hands
Even large, seemingly stable pieces of glass can shift, crack, and slice through skin without warning. If you must move a piece of glass, use thick leather work gloves — not thin rubber gloves. Hold pieces at the edges and keep your face away. In most cases, the safest move is to leave glass in place until a professional arrives.
If it was a break-in: Do not enter the room. Do not touch anything. Call 911 and wait outside your home if you feel unsafe. Burglars occasionally return, and disturbing the scene complicates the police investigation and your insurance claim. Call Expert Glass Repair only after law enforcement has cleared the scene.
Step 2: Safely Clear the Broken Window Area
Once everyone is safely away and you have proper footwear and gloves, you can begin making the area safer — not clean, just safer. Your goal at this stage is to reduce hazards, not to restore the space to normal.
Removing Large Fragments
If large pieces of glass are hanging in the frame or leaning against walls, they are a falling hazard. Using thick leather gloves, carefully remove pieces that are clearly about to fall. Place them immediately into a heavy-duty contractor bag or cardboard box — never a plastic grocery bag, which can tear under the weight and sharp edges. Tape the bag shut and label it clearly.
What Not to Vacuum (Yet)
Resist the urge to vacuum up small fragments immediately. Most standard household vacuums are not designed to handle glass — it can damage the motor and, more dangerously, cause the vacuum to recirculate fine glass particles back into the air. A stiff broom and dustpan work far better for the initial sweep. If you have a shop vacuum with a proper filter, that can work for cleanup, but wait until after the technician has completed the repair.
Identifying Glass Type: Why It Matters
How broken glass behaves depends on the type. Annealed (standard) glass breaks into large, jagged shards — dangerous but easier to see and remove. Tempered safety glass shatters into thousands of small, pebble-like pieces that scatter across a wide area. Laminated glass (common in sliding doors and skylights) tends to stay in the frame, held together by the interlayer. Learn more about these differences in our tempered glass guide and laminated glass guide.
Step 3: Temporary Weatherproofing — Protect Your Home
If your glass broke during a storm, in cold weather, or at night when a repair cannot happen immediately, you need to close off the opening. This protects against rain, wind, insects, and — critically — unauthorized entry through an open window or door.
The Plastic Sheeting Method
Heavy plastic sheeting (6 mil polyethylene, found at any hardware store) is the best temporary weatherproofing material. Cut a piece at least 6 inches larger than the opening on all sides. Tape it to the window frame using heavy-duty packing tape or duct tape — apply tape to the window frame itself, not to walls or trim if you want to avoid paint damage.
On a windy night, a single layer of plastic will billow and make noise — add a second layer to reduce movement, or tape a piece of cardboard over the plastic to add rigidity. For ground-floor windows, use extra tape on the interior side as well, as an intruder deterrent.
Using Cardboard or Plywood
For single-pane windows or broken glass doors, a sheet of cardboard or plywood provides better short-term security than plastic alone. Cut plywood to fit snugly inside the frame and secure it with screws into the frame. Neither is a permanent solution, but either can get you through the night safely while you wait for a morning appointment.
Expert Tip: When to Call for Emergency Service
For ground-floor windows, glass doors, or any opening accessible from outside, call for our emergency service rather than relying on cardboard or plastic overnight. An unboarded ground-floor opening is a real security risk. Our emergency response team carries board-up materials and can typically secure the opening quickly.
Step 4: Document Everything for Insurance
Before you clean up a single shard, take photographs. A thorough photographic record helps support any potential insurance claim, documents the extent of damage, and creates evidence of the original condition of your glass and frame. Check your specific policy for details on coverage.
What to Photograph
Wide shot
The full window or door from inside, showing the damage in context of the room.
Close-up of the break
The fracture pattern, any remaining glass in the frame, frame damage.
From outside
The exterior view, including any forced entry marks or environmental damage.
The floor below
Glass scatter pattern — useful for showing the extent and type of breakage.
Any secondary damage
Water intrusion, damaged blinds or curtains, interior water damage from storm.
Serial numbers or labels
If visible on the glass unit, document the manufacturer and any safety markings.
Working With Your Insurance Company
Once you have documented the damage, contact your homeowner's insurance company to file a claim. When you call Expert Glass Repair, let us know you are filing an insurance claim — we can provide documentation that your adjuster may need. Learn more about our insurance claim assistance.
Keep in mind that for small repairs, it may be worth paying out of pocket rather than filing a claim that could affect your premium. We will give you an honest estimate so you can make that comparison before you decide.
Step 5: How to Describe Your Emergency When You Call
When you call Expert Glass Repair at (703) 679-7741, the more information you can provide upfront, the faster and more accurately we can prepare. Here is what helps us most:
The type of opening
Is it a window (sliding, single-hung, double-hung, casement), a glass door (sliding, French, hinged), a storefront panel, or something else?
Approximate size
Your best estimate of the width and height. If you do not know, describe it relative to something: "about the size of a standard door."
Single or double pane
Look at the edge of the glass — if you can see two panes with a space between them, it is double-pane (insulated glass).
Your location
Full address including any access notes. We serve all of DC, Northern Virginia, and Maryland.
The cause
Was it a break-in, storm damage, accident, or has the glass been weakening over time?
How urgent
Are you exposed to weather? Is this a security risk? Is someone injured? Emergency dispatch is available for immediate threats.
Warning Signs of Unsafe Glass
Not every glass emergency involves a complete break. Sometimes glass becomes dangerous gradually, and knowing what to look for can prevent an injury before it happens.
Cracks That Are Spreading
A crack in a window that appeared recently and is visibly growing is a glass that is under stress and will fail. Temperature changes are often the trigger. A cracked window that is fine today may shatter on a cold morning. Do not wait on a spreading crack.
Tempered Glass "Crazed" Pattern
Tempered safety glass that has been impacted but not yet collapsed often shows a distinctive "crazed" pattern — a web of fine cracks across the entire surface. This glass has lost all structural integrity and can collapse at any moment. Treat it as an active emergency.
Edge Chips and Nicks
Chips and nicks at the edges of glass panes create stress concentrations that can trigger sudden, complete fracture. This is particularly common in older homes in the DMV area. Edge damage extending more than 1/4 inch into the pane warrants replacement.
Visible Seal Failure on Double-Pane
Fog or condensation between the panes means the seal has failed. While not an immediate safety risk, the moisture inside can freeze in cold weather, expanding and potentially cracking the glass.
If you recognize any of these warning signs, consider scheduling a free evaluation. You can also explore our double-pane window guide for more about seal failure and foggy windows.
What to Expect When the Technician Arrives
When an Expert Glass Repair technician arrives, here is what the process looks like from first contact to completed repair.
Assessment & Quote
The technician will assess the damage, measure the opening, identify the glass type needed, and provide you with a final, firm quote before any work begins.
Site Preparation
Drop cloths and protective materials are laid down around the work area. Any remaining glass in the frame will be carefully removed and bagged.
Emergency Board-Up (if needed)
If the replacement glass is not on the truck for unusual sizes, the technician will install a professional board-up to fully secure the opening while the glass is sourced.
Glass Installation
For standard residential glass, installation typically takes 30 to 90 minutes depending on the complexity. The technician will ensure the glass is properly seated, sealed, and operational.
Cleanup & Final Inspection
Thorough cleanup of the work area, walk-through of the completed repair, and care instructions. Every job is backed by our Comprehensive Workmanship Warranty.
Key Takeaways
Safety first — shoes, gloves, clear the area of kids and pets before doing anything else.
Photograph everything before cleanup — insurance claims depend on documentation.
Plastic sheeting or plywood can get you through the night safely.
Ground-floor openings are a security risk — call for professional boarding if exposed overnight.
Know your glass type (annealed, tempered, laminated) to communicate clearly with your glazier.
A spreading crack or crazed pattern is an active hazard — do not delay.

Frequently Asked Questions
What should I do first when a window breaks in my home?
Safety comes first. Put on sturdy, closed-toe shoes before approaching the area. Move children, pets, and anyone who is barefoot out of the room immediately. Do not touch broken glass with bare hands. If the break was caused by a break-in, do not enter -- call 911 and wait for law enforcement to clear the scene before going inside. Once the area is safe, wear thick leather gloves and carefully remove any large shards hanging from the frame.
How do I temporarily cover a broken window before the glazier arrives?
Cover the opening with heavy plastic sheeting (6 mil polyethylene is ideal), cut at least 6 inches larger than the opening on all sides. Secure it to the window frame using heavy-duty packing tape or duct tape. For ground-floor windows or doors where security is a concern, cut plywood to fit snugly inside the frame and secure it with screws into the frame. Avoid using thin garbage bags or newspaper -- they will not withstand wind, rain, or temperature changes in the DMV climate.
Should I vacuum broken glass off the floor?
Do not use a standard vacuum cleaner on broken glass right away. Fine glass particles can damage the vacuum motor and potentially recirculate dangerous micro-shards into the air. Instead, use a stiff broom and dustpan for the initial cleanup. After sweeping, press a dampened paper towel or piece of bread across the floor to pick up tiny fragments you cannot see. Once the visible glass is removed, you can vacuum the area with a shop vac or a standard vacuum with a fresh bag or filter.
How fast can I get emergency glass repair in the DC, Maryland, or Virginia area?
Expert Glass Repair provides emergency glass service across the entire DMV -- Washington DC, Northern Virginia, and Maryland. For ground-floor openings, break-ins, or situations where the opening cannot be secured, we prioritize same-day or next-morning response. Call (703) 679-7741 and describe the situation, including the type of opening, approximate size, and urgency level, so we can dispatch the right team with the right materials.
What information should I give my insurance company after a glass emergency?
Before cleaning up, photograph the damage from multiple angles: a wide shot showing context, close-ups of the break pattern, exterior views, the glass scatter pattern on the floor, and any secondary damage to walls, floors, or furnishings. Note any visible serial numbers or labels on the glass unit. File the claim with your insurance provider as soon as possible. Most homeowners insurance policies cover glass breakage from storms, vandalism, and break-ins, often with a deductible. We can provide detailed invoices and documentation to support your claim.
Is broken window glass dangerous even after the initial break?
Yes. Broken glass remains a safety hazard long after the initial incident. Large shards can fall from the frame hours or even days later, especially in windy conditions common in the DMV. Tiny glass fragments embed in carpet fibers and floor crevices where they can cause cuts for weeks. If the broken glass was in a door or window near a walkway, keep the area blocked off until professional repair is complete. Tempered safety glass breaks into small, relatively dull pieces, while annealed glass shatters into large, razor-sharp shards that are far more dangerous.
