Ultimate Guide: Replace Your Exterior Door Threshold Like a Pro

Replacing an exterior door threshold is a crucial step in maintaining the integrity and functionality of your home’s exterior. A threshold is the horizontal piece of material installed at the base of the door frame, acting as a barrier against water, air, and pests.

A damaged or worn-out threshold can lead to several issues, including water seepage, drafts, and insect infestations. Replacing the threshold is a relatively simple task that can be completed with basic tools and materials. Here’s a step-by-step guide on how to replace an exterior door threshold:


Materials you’ll need:

  • New threshold (made of wood, metal, or composite material)
  • Pry bar
  • Hammer or nail gun
  • Caulk gun
  • Caulk
  • Screws or nails

Step 1: Remove the old thresholdUse a pry bar to gently pry the old threshold loose from the door frame. Be careful not to damage the frame or the flooring.Step 2: Clean the areaOnce the old threshold is removed, clean the area thoroughly to remove any debris or old caulk.Step 3: Install the new thresholdPosition the new threshold in place and secure it with screws or nails. Make sure the threshold is level and flush with the door frame.Step 4: Caulk the thresholdApply a bead of caulk around the perimeter of the threshold to seal any gaps and prevent water from seeping in.Step 5: Allow the caulk to dryLet the caulk dry completely before using the door.

1. Material

The material you choose for your exterior door threshold will have a significant impact on its durability, functionality, and aesthetics. Here is a brief overview of the three most common types of threshold materials:

  • Wood: Wood thresholds are a popular choice because they are relatively inexpensive and easy to install. However, wood is not as durable as other materials and can be susceptible to rot and insect damage. Wood thresholds are best suited for areas with mild climates and low foot traffic.
  • Metal: Metal thresholds are more durable than wood thresholds and are not susceptible to rot or insect damage. However, metal thresholds can be more expensive and difficult to install. Metal thresholds are a good choice for areas with heavy foot traffic or extreme weather conditions.
  • Composite: Composite thresholds are made from a combination of wood and plastic or metal. Composite thresholds are more durable than wood thresholds and are not susceptible to rot or insect damage. They are also easier to install than metal thresholds. Composite thresholds are a good choice for areas with moderate foot traffic and weather conditions.

When choosing a threshold material, it is important to consider the following factors:

  • Climate: The climate in your area will play a role in the type of threshold material you choose. If you live in an area with extreme weather conditions, you will need a threshold material that is durable and can withstand the elements.
  • Foot traffic: The amount of foot traffic that your door will receive will also affect the type of threshold material you choose. If you have a door that is used frequently, you will need a threshold material that is durable and can withstand heavy wear and tear.
  • Aesthetics: The appearance of your threshold is also an important consideration. You will want to choose a threshold material that complements the style of your home.

By considering these factors, you can choose the right threshold material for your specific needs.

Once you have chosen a threshold material, you can follow the steps outlined in the “How to Replace an Exterior Door Threshold” section to replace your old threshold.

Replacing an exterior door threshold is a relatively simple task that can be completed in a few hours. By following the steps outlined in this article, you can ensure that your new threshold is installed properly and will provide years of trouble-free service.
