At STL Windows Direct, we understand that choosing the right replacement doors can be overwhelming. To help homeowners in St. Louis, Lake of the Ozarks, Jefferson City, and Columbia, MO, we’ve compiled a comprehensive list of frequently asked questions about door installation, maintenance, and benefits. Whether you’re considering entry doors, patio doors, sliding doors, or front doors, we’ve got you covered.

What Is a Standard Door Size?
A standard exterior door is typically 36 inches wide, 80 inches tall, and 1.75 inches thick. However, door sizes can vary based on the style and type of door. For example, patio doors and sliding doors often come in larger dimensions to provide expansive views and easy access to outdoor spaces. If you’re replacing an existing door, it’s essential to measure the current opening to ensure a proper fit.
How Do You Measure the Size of a Door?
Accurate measurements are crucial for a seamless door installation. If you’re unsure about your measurements, the team at STL Windows Direct offers professional entry door installation services to ensure a perfect fit. To measure a door for replacement, follow these steps:
- Width: Measure across the top, middle, and bottom of the door frame. Use the widest measurement.
- Height: Measure from the top of the frame to the bottom threshold.
- Depth: Measure the thickness of the door frame to ensure the new door will fit properly.
Can You Paint a Door? How?

Can a Screen Door Be Put on Any Door?
In most cases, yes. Screen doors can be installed over entry doors, patio doors, and sliding doors to allow fresh air into your home while keeping bugs out. However, it’s essential to ensure the screen door is compatible with your existing door frame. Some doors may require adjustments to the frame or additional hardware for proper installation.
How Do I Know It’s Time to Replace My Door?
If you notice any of these issues, it’s time to consider new exterior door installation to improve your home’s comfort and security. Several signs indicate it’s time for a door replacement:
- Difficulty Opening or Closing: Warped or damaged doors can be hard to operate.
- Drafts: If you feel air coming through the door, it’s likely not energy efficient.
- Visible Damage: Cracks, dents, or peeling paint can compromise the door’s functionality and appearance.
- Increased Energy Bills: An inefficient door can cause your heating and cooling systems to work harder, increasing utility costs.
Will Replacement Doors Increase the Value of My Home?
Yes, investing in new doors can boost your home’s value. A well-installed front door or patio door enhances curb appeal, improves energy efficiency, and provides added security. Potential buyers appreciate homes with updated entry doors and sliding doors that require minimal maintenance. Choosing high-quality replacement doors from STL Windows Direct can give your home an attractive and functional upgrade.
Will My Replacement Door Be Energy Efficient?

Energy-efficient doors can lower your utility bills and create a more comfortable living environment. At STL Windows Direct, our door installation services include energy-efficient options to suit your needs.
Is Steel or Fiberglass Better for My Entry Door?
The best choice depends on your priorities. If you value durability and security, a steel door may be the better option. If you prefer low maintenance and energy efficiency, consider a fiberglass door. Both steel and fiberglass entry doors have unique benefits:
- Steel Doors: These are durable, secure, and resistant to harsh weather conditions. They are ideal for homeowners looking for a cost-effective and strong front door.
- Fiberglass Doors: These doors offer superior insulation, are resistant to dents and scratches, and can mimic the look of wood without the maintenance.
How Do You Adjust an Entry Door?
