In this blog post, we will explore the reasons why you should choose a prehung steel entry door for your home.

Durability and Security
A prehung steel entry door is known for its exceptional durability and security features. Made from strong and sturdy steel, these doors provide a high level of protection for your home. Their robust construction makes them resistant to dents, cracks, and warping, ensuring that they maintain their integrity and withstand the test of time. Additionally, steel doors feature advanced locking mechanisms, reinforcing your home’s security and giving you peace of mind.

Preparing The Opening And Frame For Installation
Before installing a prehung steel entry door, it’s crucial to properly prepare the opening and frame. This ensures a smooth and secure installation, maximizing the door’s performance and longevity. In this section, we will discuss three essential steps in this preparation process: inspecting and repairing the subfloor, checking the rough opening size, and installing the sill pan.
Inspecting and Repairing the Subfloor

The subfloor plays a key role in supporting the weight of the door. Before proceeding with the installation, it’s necessary to examine the subfloor for any signs of damage or deterioration. Here’s how you can assess and repair the subfloor:
- Thoroughly inspect the subfloor for any signs of rot, moisture damage, or unevenness. Pay close attention to areas near the door opening.
- If you notice any soft spots or signs of decay, it’s crucial to replace those sections of the subfloor. Cut out the damaged portion using a circular saw or reciprocating saw, and install a new piece of plywood of the same thickness.
- Ensure that the subfloor is level and securely fastened to the floor joists. Use a straight edge and a level to check for any unevenness. If necessary, shim or sand down high spots to achieve a level surface.
Checking the Rough Opening Size
Properly measuring the rough opening is essential to ensure that the prehung steel entry door fits snugly and functions correctly. Here’s how you can check the rough opening size:
Steps | |
---|---|
Measure the width of the rough opening at three points: top, middle, and bottom. Take the smallest measurement and subtract 1/2 inch to allow for the shimming and adjusting during installation. | |
Measure the height of the rough opening at three points: left, center, and right sides. Take the smallest measurement and subtract 1/2 inch for the same reasons as above. |
Installing the Sill Pan
The sill pan provides an extra layer of protection against water damage by preventing moisture from seeping under the door. Here’s how you can install the sill pan:
- Measure the width of the door sill and cut the sill pan flashing to the same width.
- Position the sill pan at the bottom of the rough opening, ensuring that it extends beyond the sides by at least 4 inches.
- Secure the sill pan by using roofing nails, evenly spaced approximately 8 inches apart.
- Apply a bead of silicone caulk along the inner edge of the sill pan to create a watertight seal.
By following these steps to prepare the opening and frame, you’ll be well on your way to a successful installation of a prehung steel entry door. Next, we will discuss the actual installation process, so stay tuned for the next section!

Checking the Fit of the Door
Before installing the prehung steel entry door, it is crucial to ensure that it fits properly. Follow these steps to check the fit:
- Measure the width of the door frame opening from inside jamb to inside jamb at the top, middle, and bottom.
- Measure the height of the door frame opening from the top of the header to the floor on the left, center, and right sides.
- Compare these measurements with the dimensions of the prehung steel entry door. The door should be slightly smaller than the frame opening, allowing for adjustments during installation.

- Measure the gap between the door frame and the rough opening.
- Cut a piece of insulation foam to fit the measured dimensions.
- Insert the insulation foam into the gap, pressing it firmly against the frame.
- Seal any remaining gaps with caulk or foam sealant.
Insulating around the door frame will not only improve energy efficiency but also provide better soundproofing and create a more comfortable indoor environment.
Installing Exterior Trim
Exterior trim not only enhances the aesthetic appeal of your entryway but also provides an additional layer of protection against the elements. Follow these steps to install exterior trim:
- Measure and cut the trim pieces to the appropriate length and angle.
- Apply exterior-grade adhesive or sealant along the back of the trim pieces.
- Position the trim pieces against the door frame and press them firmly in place.
- Secure the trim pieces by using finishing nails or screws, making sure they are flush with the door frame.
- Fill any nail holes or gaps with wood putty, and sand it smooth once it dries.
Installing exterior trim not only adds a finishing touch to your entryway but also helps to seal any potential gaps and protects the door frame from moisture and damage.
By following these steps to properly insulate and weatherproof your entryway, you can improve energy efficiency, reduce drafts, and create a more comfortable and secure home environment. Don’t forget to regularly inspect and maintain the weatherstripping and exterior trim to ensure their effectiveness.
