What You'll Learn
The importance of sill pans
Sill pans are an important component of door installation, serving as a critical defence against water damage and helping to maintain the structural integrity of a building.
Firstly, sill pans act as a protective barrier, preventing water from seeping underneath the door and causing damage to the underlying framing and subfloor. This is especially important for exterior doors that are unprotected by roofs or overhangs, as water can easily find its way into the building through cracks or crevices. By collecting and redirecting water, sill pans help to prevent the growth of mould and rot, which can be costly to repair.
Secondly, sill pans are essential for proper flashing, which involves sealing gaps and joints to create a waterproof barrier. Flashing tape, often used in place of a sill pan, is inadequate as it lacks the necessary slope for effective drainage and does not include a back dam to prevent water and air infiltration. Sill pans, when properly installed and sealed, ensure that water drains to the exterior, protecting the interior of the building.
In addition, sill pans are particularly important in cold climates. Metal sill pans, due to their high conductivity, can cause condensation, which can damage finished flooring and the subfloor. Plastic sill pans, which are less conductive, are a better alternative in such cases.
Furthermore, sill pans are crucial for doors with wood flooring inside. Without a sill pan, water can seep under the door and cause the wood to rot. This is a common issue that contractors are often called in to repair.
Overall, sill pans play a vital role in safeguarding a building from water damage, mould, and rot. Proper installation and sealing of sill pans are essential to ensure their effectiveness in protecting the structure and integrity of a building.

Choosing the right materials
Climate Considerations:
Avoid using metal sill pans in cold climates. Metal is a highly conductive material, which creates a direct line from the inside to the outside of your door. This can make the inside of the sill pan a condensing surface, leading to condensate that damages your flooring and subfloor. If you live in an area with cold weather, consider alternative materials like plastic or flexible membranes.
Water Resistance:
The primary function of a door sill pan is to prevent water intrusion. Ensure that the material you choose is water-resistant or waterproof. Materials such as copper, lead, plastic, or flexible membranes are effective at keeping water from seeping underneath the door. You can also use caulking as a secondary defence, but it should not be the primary method of water protection.
Proper Drainage:
Select a sill pan with the proper slope to allow water to drain towards the exterior. Avoid using flashing tape as it often lacks the necessary slope and can result in water infiltration. A Z-shaped sill pan is recommended as it directs water away from the door and towards the exterior.
Sealants:
Using the correct sealant is essential to creating an effective barrier against air and water infiltration. Refer to the door manufacturer's instructions to determine the specific sealants compatible with your sill pan. Common sealants used include caulk or PL premium.
Compliance with Building Codes:
Check your local building codes to ensure that your chosen materials comply with the required standards. Many states have adopted the International Residential Code, which includes specific requirements for "pan flashing" at door sills. Using pre-made kits from manufacturers can help ensure you have all the necessary components for a compliant installation.
Remember, the right materials for your door sill pan will depend on your specific needs and local conditions. Taking these factors into consideration will help you make an informed decision and create an effective barrier against water and air intrusion.

Installation steps
Before beginning the installation, ensure that you have the necessary materials and tools, such as a sill pan, sealant or adhesive, a hammer tacker, a j-roller, flashing, and any other recommended items.
First, prepare the door opening by installing flashing. This involves protecting the sill, the bottom of the jack studs, and, if possible, the face of the sheathing. This step is often excluded from door instruction manuals, but it is essential for proper installation.
Next, apply the appropriate sealant or adhesive to the underside of the door sill. This step is crucial for preventing water and air infiltration. Choose an exterior-grade sealant or adhesive that will not shrink and is compatible with the surfaces. Pay attention to the sealant pattern, as this will impact its effectiveness. Create a back dam with the sealant to prevent water from reaching the finished floor, and provide an exit route for any water that may enter.
If your door has weep holes, ensure they are not accidentally covered by caulking or sealant. These holes are essential for drainage and should remain unobstructed.
Now, carefully place the door into the opening, ensuring that it is set correctly on the sealant without smearing the pattern. Follow the manufacturer's instructions for the specific sealant being used.
Finally, check that the door is installed correctly by testing its performance. A properly installed door should repel wind and water, open and close smoothly, lock and unlock effortlessly, and perform for decades without requiring adjustments.

Common mistakes
Building a door sill pan can be a tricky process, and there are a few common mistakes that people often make. Here are some detailed explanations of these errors, along with some instructive tips on how to avoid them.
One of the most common mistakes is the improper use of flashing tape. Builders often wait until they are installing the door to think about the sill pan, and rather than delay the construction, they opt for a quick solution by fashioning a sill pan out of flexible flashing tape. This method is problematic because it lacks a back dam, which is essential to prevent air and water infiltration. Flashing tape sill pans also tend to have an inadequate slope, which can hinder proper water drainage to the outside. Additionally, they are prone to damage when the door is slid into place. To avoid this mistake, it is advisable to plan ahead and purchase a ready-made sill pan with the correct slope and drainage features. These pre-made pans are available from manufacturers for around $30 and will ensure your door has the necessary protection.
Another common issue is the use of improper sealant. Even when a proper sill pan is installed, builders may be uncertain about choosing the right sealant to create an effective barrier. Using the wrong caulk or sealant can lead to unwanted air and water intrusion. To prevent this problem, builders should carefully follow the door manufacturer's instructions to select the appropriate sealant that meets the required standards and codes.
Not following the correct codes is another frequent mistake. While more and more states are adopting codes mandating properly installed sill pans, some builders may overlook these requirements. Section R703.8.1 of the International Residential Code specifically requires "pan flashing" to be installed on doors and windows, either according to manufacture instructions or to code. Builders should familiarize themselves with the relevant codes and ensure their installations comply with these standards to avoid faulty installations and potential issues with moisture and mould.
In addition to these mistakes, it is worth noting that omitting a sill pan altogether under an exterior door can be risky. While an overhang or porch roof may provide some protection, it is not a guarantee against water damage. Skipping the sill pan can lead to expensive repairs due to rot and mould, which can quickly spread to the subfloor and damage hardwood floors. Therefore, it is always recommended to include a sill pan to prevent water from seeping into the building.
Finally, while metal sill pans are commonly used, they can be problematic in cold climates. Metal is a highly conductive material, and in cold conditions, it can cause the inside of the sill pan to become a condensing surface. This condensation can then damage the finished flooring and the subfloor. To avoid this issue, it is advisable to opt for plastic sill pans or other suitable alternatives in cold climates.
