Installing a threshold on concrete is an essential step in creating a smooth transition between rooms while also protecting your flooring and doors from wear and tear. Whether you’re working on a new construction project or updating an existing space, this guide on how to install threshold on concrete will take you through the steps needed to properly install a threshold on concrete.

With the right tools and techniques, you can achieve a secure and professional finish that ensures durability and functionality.
Why Install a Threshold on Concrete?
A threshold serves multiple important purposes when installed on concrete. It helps to create a smooth and safe transition between rooms, reducing the risk of tripping or damage to floors. Additionally, thresholds act as a barrier to keep out dust, dirt, water, and drafts, improving the overall insulation and cleanliness of your space.
They also enhance the durability of your doorway by minimizing wear and tear caused by constant foot traffic. Beyond functionality, thresholds can contribute to the aesthetic appeal of a room, offering a polished and finished look that complements your flooring and interior design.
Needed Materials
Before you begin the installation process, gather all necessary materials to ensure a smooth and efficient process. You will need:
A Threshold of Your Choice
Thresholds come in various materials, including wood, metal, and PVC. Choose one that complements the style of your doorway and works well with your flooring.
Measuring Tape
Measuring tape will help you determine the length and width of your threshold for accurate placement and cutting.
Chalk or Marker
Chalk or a marker will help you mark where to make cuts on the threshold before installation.
Jigsaw
A jigsaw equipped with a metal-cutting blade is necessary for cutting through tougher materials like metal thresholds.
Drill and Screws
You will need a drill to secure the threshold into place using screws. Make sure to use screws specifically designed for concrete.
Adhesive
An adhesive like construction glue or silicone sealant is essential for securely attaching the threshold to the concrete surface.

Safety Equipment
Wearing safety glasses, gloves, and a dust mask is crucial when working with tools and materials to protect yourself from potential hazards.
8 Step-by-step Guides on How to Install Threshold on Concrete
Step 1: Measure the Width of the Doorway
Start by measuring the width of the doorway where the threshold will be installed. Use a measuring tape to get an accurate measurement from one side of the doorway to the other. Be sure to measure at the base of the doorway since this is where the threshold will sit.
Record the measurement and transfer it to your threshold material to ensure it is cut to the correct length. Accurate measurements are crucial for achieving a secure and professional fit.
Step 2: Prepare the Threshold for Cutting
Once you have recorded the measurement of the doorway, lay the threshold material on a stable work surface. Use chalk or a marker to clearly mark the cutting points based on the measurement you took. Double-check your measurements to ensure accuracy, as precise cutting is key to achieving a proper fit.
If your threshold is made of metal or another rigid material, ensure you have a jigsaw or appropriate cutting tool ready. Secure the threshold firmly with clamps to prevent movement while cutting, and wear your safety equipment, such as gloves and safety glasses, to protect yourself during this step.
Step 3: Cut the Threshold to Size
Using a jigsaw or other cutting tool, carefully cut along the marked lines on your threshold material. Take your time and make sure you are following the lines accurately for a clean and precise cut. If you are using a metal-cutting blade, be aware of any sparks that may occur during the cutting process.
Once the threshold is cut to size, use sandpaper or a file to smooth out any rough edges.
Step 4: Prepare the Surface for Installation
Before attaching the threshold, it is essential to prepare the concrete surface where it will be installed. Use a broom or vacuum cleaner to remove any dirt or debris from the surface. If there are any bumps or uneven areas, use a chisel and hammer to smooth them out for a flat surface.

Butt the threshold against the doorway to ensure it fits correctly and make any final adjustments if needed.
Step 5: Apply Adhesive
Using a construction glue or silicone sealant, apply a generous amount along the back of the threshold, where it will come in contact with the concrete surface. Be sure to cover the entire length of the threshold for maximum adhesion.
It is essential to use an adhesive specifically designed for threshold installation on concrete, as this will ensure a strong and long-lasting bond.
Step 6: Place the Threshold
Carefully place the threshold in its designated position against the doorway. Press down firmly to secure it in place and ensure proper adhesion to the concrete surface.
If there is any excess adhesive seeping through the sides, wipe it away with a damp cloth before it dries.
Step 7: Secure with Screws
To ensure maximum stability, drill screws into the pre-drilled holes on your threshold. Make sure to use screws that are suitable for use on concrete surfaces. You can also add some extra adhesive around the screws for added reinforcement.
The number of screws needed will depend on the length and weight of your threshold, but make sure to have a screw at each end and evenly spaced in between.
Step 8: Allow Time for Drying
After the threshold is securely in place, allow time for the adhesive to dry completely. This could take anywhere from a few hours to a full day, depending on the type of adhesive used. Be sure to follow the manufacturer’s instructions for drying time and avoid walking on the threshold until it is fully dried.

Congratulations! You have successfully installed a threshold on concrete. Enjoy your safe and seamless doorway transition with improved insulation and durability.
Following these step-by-step guides on how to install threshold on concrete will ensure a professional and sturdy installation of your threshold on concrete. Remember to always take accurate measurements, wear safety equipment, and use the appropriate tools and materials for a successful project. Happy threshold installing!
Additional Tips
- If you are unsure about cutting the threshold yourself, consider hiring a professional to ensure accuracy and efficiency.
- When choosing an adhesive, make sure it is suitable for both indoor and outdoor use if your threshold is located on an exterior doorway.
- Add caulking around the edges of the threshold for a more finished look and to prevent any drafts or moisture from seeping in.
- Regularly check for any cracks or damage to the threshold and make repairs as needed to maintain its functionality.
- If you need to remove an old threshold, be sure to properly dispose of it and follow any local regulations for the disposal of construction materials.
- Always prioritize safety and take necessary precautions when working with tools and materials. Happy threshold installing! And remember, a well-installed threshold can improve the appearance and functionality of your doorway for years to come.

Frequently Asked Questions
Q1: Can I Install a Threshold on Concrete Without Using Screws?
A: While using adhesive alone may be sufficient for some thresholds, it is recommended to use both adhesive and screws for a more secure installation. This will also help distribute the weight of the threshold evenly and prevent any potential movement or shifting.
Q2: How Do I Remove Excess Adhesive from the Threshold?
A: If you notice any excess adhesive seeping through the sides during installation, simply wipe it away with a damp cloth before it dries. If it has already dried, use a chisel or scraper to carefully remove it without damaging the threshold.
Q3: Can I Use Any Type of Adhesive for Installing a Threshold on Concrete?
A: It is essential to use an adhesive specifically designed for threshold installation on concrete, as this will ensure maximum adhesion and durability. Regular construction glue or silicone sealant may not hold up well on concrete surfaces.
Q4: Do I Need to Seal the Threshold After Installation?
A: While it is not necessary, adding a layer of caulking around the edges can help improve insulation and prevent any drafts or moisture from seeping in. However, this step is optional and depends on personal preference.
Conclusion
Installing a threshold on concrete may seem like a challenging task at first, but with the right tools, materials, and step-by-step guidance, it can be a straightforward and rewarding DIY project.
