How Do Restoration Pros Secure Broken Windows After a Fire?

Last updated October 26, 2026

The short answer

Initial Assessment

Before securing a broken window, pros first inspect the frame and surrounding wall for heat damage or structural weakness. They check if the glass is fully shattered or if jagged shards remain. This assessment determines the safest approach and whether the window can be boarded directly or needs extra support.

If the frame is charred or warped, they may reinforce it with additional wood or metal brackets. The goal is to create a stable surface for the temporary covering. This step also helps identify any fire damage that might affect the window's eventual replacement.

Boarding the Window

The most common method is to cover the opening with plywood. Pros measure the window dimensions and cut a sheet of plywood to fit snugly inside the frame or over the exterior. They secure it with screws or nails driven into the surrounding structure, not just the glass frame.

For larger windows or those with odd shapes, they may use multiple boards or a combination of plywood and plastic sheeting. The covering is designed to stay in place until a permanent window can be installed. This protects against rain, wind, and unwanted entry.

  • Plywood thickness usually ranges from 1/2 to 3/4 inch.
  • Screws are preferred over nails for easier removal.
  • Heavy-duty plastic can be used for temporary weatherproofing.
  • Boards should overlap the frame by at least 2 inches.
  • Secure all edges to prevent lifting in high winds.

Weatherproofing and Insulation

After boarding, pros add weatherproofing to keep out moisture and drafts. They may apply caulk or foam insulation around the edges of the board. This is especially important in humid climates where storms can bring heavy rain and hail.

In some cases, they install a layer of plastic sheeting over the plywood for extra protection. This helps maintain indoor temperatures and reduces the risk of water damage to the interior. Proper sealing also prevents insects and debris from entering your home.

Safety Considerations

Securing a broken window is not just about keeping weather out; it also addresses safety hazards. Pros remove loose glass shards and vacuum up debris to prevent injuries. They may also place warning tape or signage if the area is accessible to others.

If the fire caused structural damage around the window, pros might advise you to avoid that area until it is inspected. Your safety is the priority. They will also check that the boarding does not block emergency exits or create new hazards.

Next Steps for Homeowners

Once the window is secured, you should contact your insurance company to report the damage. Policies vary, and your insurer decides what is covered. They will guide you on the claims process and may recommend a professional for permanent repairs.

In the meantime, keep the area clear and avoid touching the boards if they seem loose. If you live in Tulsa, remember that spring storms can be severe, so a secure temporary cover is vital. When the time comes, a local water damage pro can help with any water-related issues that arise from the fire or weather.

Frequently asked questions

How long can a boarded window stay in place?

Typically, a boarded window can remain for several weeks or even months, depending on the weather and the extent of damage. It should be checked regularly for loosening. Permanent repair should happen as soon as possible to restore full security and insulation.

Can I secure the window myself instead of calling pros?

You can, but it's risky if the frame is damaged or the window is high up. Pros have the right tools and know how to secure it safely. If you do it yourself, use thick plywood and screws, and check it after storms.

Will my insurance cover the cost of boarding?

Policies vary, and your insurer decides what is covered. Emergency boarding is often included in fire damage claims, but you should check your policy. Document the damage and keep receipts for any materials you buy, as they may be reimbursable.
