The short answer

Plywood and OSB Panels

Plywood is the most common material for boarding up windows, doors, and other openings after water damage or storms. It comes in large sheets, usually 4 by 8 feet, and can be cut to fit almost any opening. Plywood offers a solid barrier against weather, debris, and intruders. Thicker sheets, like 5/8 inch or 3/4 inch, provide more strength and are often used for larger gaps.

Oriented strand board, or OSB, is another option. OSB is made from wood strands pressed together with adhesive, making it strong and less expensive than plywood. It works well for temporary protection, though it can be more prone to swelling if it gets wet. The pros choose between plywood and OSB based on the specific opening and how long the board-up needs to stay in place.

  • Plywood sheets in various thicknesses
  • OSB panels for cost-effective coverage
  • Particle board for light-duty situations
  • Metal sheets for extra security
  • Polyethylene sheeting for moisture barrier
  • Plywood with fire-retardant coating

Framing Lumber and Fasteners

To secure the panels, the pros use framing lumber like 2x4s or 2x6s. These boards create a frame around the opening, giving the plywood or OSB something solid to attach to. The frame also adds structural support, especially for larger windows or doors. Without proper framing, a board-up can be weak and easily pushed in.

Fasteners are just as important as the panels. Screws, especially exterior-grade ones, hold better than nails and resist pulling out under wind or pressure. The pros might use lag bolts for heavy-duty situations. They also use construction adhesive in some cases. Each fastener type serves a purpose, and the choice depends on the material and the expected stress.

Sealants and Moisture Barriers

Water damage often leaves openings where rain or humidity can get in. To keep moisture out, the pros apply sealants like caulk or expanding foam around the edges of the board-up. These materials fill gaps and prevent water from seeping through. A tight seal is key to protecting the interior until permanent repairs happen.

Moisture barriers, such as plastic sheeting or tarps, might be layered over the boards. This adds an extra defense against rain and wind. In a humid climate, keeping moisture out is especially important, as damp conditions can worsen mold growth. The pros use these barriers to keep the space as dry as possible. Policies vary, and your insurer decides what is covered.

Tools and Equipment Used

Board-up work requires the right tools. The pros bring circular saws or reciprocating saws to cut panels and lumber to size. Drills and impact drivers make quick work of driving screws. Measuring tapes and levels ensure the boards fit flush and are straight. Safety gear, like gloves and goggles, protects the workers during the job.

For larger openings, the pros might use ladders or scaffolding to reach high windows. They also use pry bars and hammers to remove damaged materials before installing the board-up. These tools allow for precise, secure installations. The right equipment makes the difference between a temporary fix that holds and one that fails.

Choosing the Right Material

The material choice depends on the situation. For a broken window from a storm, plywood is often enough. For a door that needs to stay secure for weeks, metal sheeting might be better. The pros assess the damage and the risk of further issues, like theft or weather, before deciding. They also consider the size and shape of the opening.

Cost is a factor, but the primary goal is protection. Plywood is usually less expensive than metal, but metal lasts longer. The pros might combine materials, like using plywood with a metal overlay. Ultimately, the right material is the one that provides adequate safety and security for the homeowner's specific needs. The pros explain the options so you can make an informed decision.

Frequently asked questions

How long does a board-up last?

A temporary board-up can last from a few days to several weeks, depending on the materials and weather. Plywood and OSB are fine for short-term use, but they can degrade with prolonged moisture. Metal panels last longer. The pros can advise on the expected duration based on your situation.

Can I board up my own windows?

You can try, but it takes skill to cut panels accurately and secure them properly. Improperly installed boards can blow off in high winds or leave gaps for water. The pros have the tools and experience to do it safely. If you attempt it, use thick plywood and exterior screws.

What if I have a large opening?

Large openings, like sliding glass doors, need special attention. The pros use multiple panels and extra framing to ensure stability. They might also use metal supports. The goal is to create a barrier that withstands weather and security risks. The pros measure carefully and use the right materials for the size.
