Why You Should Replace Exterior Door
Your exterior door is more than just an entry point. It protects your home from weather, keeps your family safe, and sets the tone for your house’s style. Over time, doors can warp, crack, or become outdated. Here are some clear reasons to replace your exterior door:
Energy Efficiency: Old doors often have gaps or poor insulation. A new door can reduce drafts and lower your energy bills.
Security: Modern doors come with stronger materials and better locks, making your home safer.
Curb Appeal: A fresh door can dramatically improve your home’s appearance and increase its value.
Functionality: If your door sticks, squeaks, or doesn’t close properly, replacement is often the best solution.
Replacing your exterior door is an investment that pays off in comfort, safety, and style.

How to Replace Exterior Door: Step-by-Step
Replacing an exterior door might seem intimidating, but with the right tools and instructions, you can do it yourself or know what to expect when hiring a professional. Here’s a straightforward process to follow:
1. Measure Your Door Opening
Before buying a new door, measure the width, height, and thickness of your current door and frame. Measure the rough opening (the space in the wall where the door fits) to ensure the new door will fit perfectly.
2. Choose the Right Door
Select a door that fits your style, budget, and needs. Common materials include:
Wood: Classic look, customizable, but requires maintenance.
Steel: Durable, secure, and low maintenance.
Fiberglass: Energy-efficient, resistant to dents and weather.
Consider features like glass panels, sidelights, and finishes.
3. Remove the Old Door and Frame
Carefully take out the old door by removing the hinge pins and lifting the door off. Then, remove the door frame by unscrewing or prying it away from the wall. Be cautious not to damage the surrounding wall or trim.
4. Prepare the Opening
Clean the rough opening and check for any damage. Repair any rot or gaps. Apply flashing tape or weatherproofing to protect against moisture.
5. Install the New Door Frame
Place the new door frame into the opening. Use shims to level and plumb the frame. Secure it with screws through the frame into the wall studs.
6. Hang the Door
Attach the door to the hinges on the frame. Check that it swings smoothly and closes tightly. Adjust the hinges or shims if needed.
7. Seal and Finish
Apply weatherstripping around the door to prevent drafts. Caulk around the frame to seal gaps. Install any trim or molding to complete the look.
8. Test the Door
Open and close the door several times to ensure it operates correctly. Check the lock and handle for smooth function.
If you prefer, you can always hire experts for exterior door replacement to guarantee a perfect fit and finish.

Choosing the Best Door Material for Your Home
Picking the right material for your new exterior door is crucial. Each option has pros and cons depending on your climate, budget, and style preferences.
Wood Doors
Wood doors offer a warm, traditional look. They can be painted or stained to match your home’s exterior. However, wood requires regular maintenance to prevent warping, cracking, or rotting, especially in humid or rainy climates.
Steel Doors
Steel doors are strong and secure. They resist dents and provide excellent insulation. They often come with a wood grain finish to mimic real wood. Steel doors are low maintenance but can rust if scratched or exposed to moisture.
Fiberglass Doors
Fiberglass doors are durable and energy-efficient. They resist dents, scratches, and weather damage. Fiberglass can be painted or come pre-finished. This material is ideal for homes in extreme weather areas.
Glass and Decorative Options
Many exterior doors include glass panels or sidelights for natural light. Choose tempered or insulated glass for safety and energy efficiency. Decorative glass can add style but may reduce privacy.
Consider your home’s style, your budget, and how much maintenance you want to do when selecting your door material.

Tips for a Smooth Exterior Door Replacement
Replacing an exterior door is a big project, but these tips will help you avoid common pitfalls:
Plan Ahead: Order your door well in advance to avoid delays.
Check Local Codes: Some areas have building codes for door installation, especially for fire safety.
Use Quality Hardware: Invest in good locks, hinges, and handles for durability and security.
Weatherproof Properly: Seal all gaps to prevent drafts and water damage.
Get Help if Needed: Doors can be heavy and tricky to install alone. Ask a friend or hire a pro.
Keep Your Home Secure: If you remove your main door, plan for temporary security.
Following these tips will make your exterior door replacement easier and more successful.
