Door Installation & Replacement Guide

How can Modernize help with your door replacement project?

Installing New Exterior Doors

Replacing exterior doors is a quick upgrade that brings long-term benefits. It enhances your home’s curb appeal, increases energy efficiency, and boosts security, all in just a few hours of installation time. Whether you’re looking to replace a worn-out entry door or want a new patio slider, the right door makes a big difference in both comfort and style.

Common reasons for replacement include damage like cracking, swelling, or rotting, as well as air leaks or difficult operation. A door that no longer closes properly or allows drafts can reduce energy efficiency and home security. Fortunately, replacing your door can solve all of those issues and give your home an instant visual refresh.

Common Materials Used for Exterior Doors

Your door’s material affects how it performs and how much upkeep it needs. Here’s a quick breakdown of the most common options:

  • Steel: Strong, affordable, and energy efficient. Good for security and low maintenance, but can dent or scratch.
  • Fiberglass: Durable, weather-resistant, and mimics wood. Low upkeep and energy efficient. Ideal for harsh climates.
  • Wood: Offers a traditional, custom look. It’s sturdy and secure but needs regular sealing or painting to avoid warping.
  • Aluminum: Rust-resistant and low maintenance. Often used for storm or patio doors. Custom entry doors are available but pricey.
  • Vinyl: Cost-effective and weather-resistant. Common for patio doors. Easy to clean and maintain.
  • Wrought Iron: Heavy-duty and decorative. Adds security and curb appeal. Often paired with glass for natural light.

Whether you’re installing a sleek new front door or replacing a worn patio slider, an exterior door upgrade can dramatically change the look and feel of your home.

Frequently Asked Questions

When should I replace my exterior door?

Replace your door if it’s drafty, hard to open or close, cracked, or showing signs of water damage. A door that lets in air or water can affect comfort and energy bills.


Can I replace a door without replacing the frame?

Yes. If the existing frame is in good condition and square, a slab door replacement is possible. Otherwise, a pre-hung door (with a new frame included) may be needed.


How long do replacement doors last?

With proper maintenance, fiberglass and steel doors can last 20 to 40 years. Wood doors may need more care but can also last decades.


What is ENERGY STAR and how does it apply to doors?

ENERGY STAR® is a government-backed certification for energy-efficient products. Doors with this label meet high standards for insulation and performance.


How Does a Door Replacement Work?

Door replacement typically begins with an inspection and measurements to ensure the new door fits properly. The homeowner selects the door type, material, and style, including optional accessories like sidelights, transoms, or smart locks. Then, a contractor removes the old door, makes any necessary frame repairs or adjustments, and installs the new unit.

There are two main types of installations:

  • Pre-Hung Doors: These come with the frame, hinges, and hardware attached. Ideal for new construction or when replacing damaged door frames.
  • Slab Doors: These are just the door itself and are installed in an existing frame. Best for simple upgrades where the structure is sound.

Most installations are completed in one day, depending on complexity and customization. Professional installation ensures proper sealing and alignment for long-term performance.

Frequently Asked Questions

What’s the difference between pre-hung and slab doors?

Pre-hung doors include the frame and are easier for full replacements. Slab doors are just the panel and work for frame-only updates.


Will replacing a door increase my home’s energy efficiency?

Yes. New doors, especially those with foam cores, weatherstripping, and ENERGY STAR ratings, seal out drafts and help regulate temperature indoors.


Can I install a new door myself?

While DIY is possible, professional installation ensures proper fit, energy efficiency, and avoids common alignment problems. This is especially important for exterior doors.


How much time does it take to install a door?

Most replacements take 2 to 6 hours. Complex projects involving structural adjustments may take longer.


What Are the Different Types of Doors?

There are many types of doors available, each offering different benefits in terms of function, style, and placement in the home.

Different areas of your home call for different door styles. When choosing a new exterior door, consider both the location — front, back, or patio — and how the door should function in that space. Some doors maximize security or light, while others focus on airflow or design.

Common Door Styles

  • Flush Door: Flat and smooth, with a minimalist look. Best for modern homes.
  • Paneled Door: Features raised or recessed panels. Classic design, fits many home styles.
  • Full Glass Door: Often used for patios. Provides maximum light and visibility.
  • Half Glass Door: Combines light with privacy. Common for front or back doors.
  • Sliding Glass Door: Saves space and offers a wide view. Ideal for patios or decks.
  • Glass Paneled Door: Includes decorative or textured glass sections. Adds style while allowing light.
  • Double Doors: Two doors that open from the center. Great for large entryways.
  • Louver Door: Includes horizontal slats for airflow. Typically used in utility spaces.
  • French Doors: Hinged double doors with glass panels. Elegant and perfect for patios or balconies.
  • Storm Door: Installed in front of an exterior door for weather protection.
  • Folding Doors: Multiple panels that fold open. Useful for wide outdoor access.
  • Sidelight Doors: Feature narrow glass panels on one or both sides. Enhances curb appeal and lets in light.

Match the style and function of the door to the area of the home where it will be installed. For example, a sliding or French door works well for patios, while paneled or sidelight doors enhance front entryways.

Frequently Asked Questions

What’s the most secure type of exterior door?

Doors with minimal glass, solid cores, and limited access points offer the highest security. Styles like solid flush doors or paneled doors without windows are more secure than full-glass or double doors. For added safety, look for doors with reinforced frames and deadbolt locks, regardless of the style.


Are patio doors energy efficient?

Modern patio doors with double or triple-pane glass and thermal breaks can be very energy efficient. Look for ENERGY STAR-rated options.


Can I get a door with built-in blinds or screens?

Yes. Many patio doors offer internal blinds or integrated screen doors for convenience and added privacy.


What door type works best in humid or wet climates?

Fiberglass doors resist moisture and warping, making them ideal for humid or coastal areas.


Choosing the Right Door for Your Home

Picking the right door depends on a mix of practical and aesthetic considerations. The ideal door should complement your home’s style, stand up to your climate, and meet your performance needs, whether that’s insulation, soundproofing, or security.

Key Factors to Consider

  1. Durability: Choose materials that can withstand your local weather and require minimal maintenance.
  2. Aesthetic Appeal: Match the door’s color, style, and hardware to your home’s exterior or interior decor.
  3. Functionality: Consider how often the door is used, whether it needs a wide opening for accessibility, or if glass panels are desired.
  4. Budget: Costs vary based on material, design, and labor. Determine how much you want to spend upfront and on long-term maintenance.

Consulting a professional contractor can help weigh these factors and make sure your door meets all of your goals.

Frequently Asked Questions

What material is best for front doors?

Fiberglass and steel are top choices for durability and efficiency. Wood offers a classic look but needs more upkeep.


How can I make sure my new door fits my home’s style?

Look for designs that echo architectural details on your home, like paneling, trim, or window styles.


Is it worth spending more on a higher-quality door?

Yes. Quality doors last longer, save on energy bills, and improve home security, making them a worthwhile investment.


What color should I choose for my front door?

Choose a color that contrasts with your siding for visual appeal or coordinates for a subtle look. Colors like red, navy, or black are popular, but some homeowners like to go for more “fun” colors like yellow or green.


Main Components of a Door System

Every door system includes several parts that work together to provide stability, insulation, and function. Knowing these components helps homeowners understand what’s being replaced or added during a project.

Key Parts of a Door System

  • Door Slab: The main part of the door. May be solid or include glass.
  • Frame: Supports the door and attaches it to the wall.
  • Hinges: Allow the door to swing open and closed.
  • Threshold: The bottom strip the door closes against; helps with sealing.
  • Weatherstripping: Seals gaps to prevent drafts and water entry.
  • Lockset/Handle: Provides security and functionality.
  • Glass Panels or Inserts: Found in many exterior and patio doors for light and design.
  • Sidelights and Transoms: Decorative windows alongside or above the door.

Frequently Asked Questions

What is the difference between a door frame and a jamb?

The frame surrounds the door and supports it. The jamb is the vertical part of the frame that the door rests against when closed.


Why is weatherstripping important?

It seals gaps between the door and frame to block drafts, moisture, and pests, improving comfort and energy savings.


Do I need to replace the threshold during a door upgrade?

Often yes, especially with pre-hung doors. A new threshold ensures a tight seal and proper fit.


Can I add sidelights to an existing door?

Only if space and structure allow. In most cases, this requires widening the opening and installing a new frame.


Are door handles included in the replacement?

Some door packages include basic hardware. Many homeowners choose to upgrade to match style or security needs.


How to Maintain Your Doors

Routine door maintenance helps extend its lifespan and ensures it operates smoothly. It’s especially important for wood doors or doors exposed to harsh weather.

Maintenance Tips

  • Inspect Regularly: Check for signs of damage, warping, or sticking.
  • Clean Surfaces: Wipe down wood, metal, and glass with appropriate cleaners.
  • Lubricate Hinges: Use oil or spray to prevent squeaking and rust.
  • Repaint or Refinish: Wood doors need a new coat every few years to prevent rot.
  • Seal Gaps: Replace weatherstripping and check caulking annually.
  • Test Locks and Hardware: Tighten screws and replace any worn parts.

Frequently Asked Questions

How often should I maintain my doors?

Inspect them seasonally, especially after weather extremes. Clean and lubricate parts twice a year.


How do I clean a fiberglass or steel door?

Use mild soap and water. Avoid harsh chemicals that could damage the finish.


When should I refinish a wood door?

Every 2 to 3 years or when the finish begins to fade, crack, or peel. Refinish promptly to prevent water damage.


Should I repair or replace worn weatherstripping?

If you feel drafts or see visible gaps, replace the weatherstripping. It’s an inexpensive fix that improves comfort and efficiency.


Door Replacement and Installation Costs

Door replacement costs can vary widely based on the type of door, materials used, and your region’s labor rates. Basic interior doors are more affordable, while high-end entry or patio doors with custom glass or smart locks will cost more.

Average Door Installation Costs

  • Interior Doors: $150 to $400 per door
  • Exterior Entry Doors: $400 to $1,000
  • Patio Doors: $500 to $1,300
  • Custom or Decorative Doors: $1,000 to $5,000+

Additional factors include the condition of the existing frame, any needed structural work, and add-ons like sidelights or security upgrades. Always get multiple quotes to compare pricing and ensure you’re getting a fair rate.

Frequently Asked Questions

Why do patio doors cost more to install?

They’re larger, often include glass panes, and may require precise alignment and waterproofing, all of which add to the labor and material cost.


Does installation usually include removing the old door?

Most professional installers will remove and dispose of the old door as part of the project. Confirm this when reviewing your estimate.


How can I save money on a door replacement?

Choose a standard size, avoid custom finishes, and compare at least three contractor quotes. Look for rebates if the door is ENERGY STAR certified.


Do contractors charge separately for hardware or accessories?

Some do. Clarify in your quote whether locks, knobs, and other accessories are included or priced separately.


Common Issues and Troubleshooting Tips for Doors

Even high-quality doors can develop issues over time. Some problems are easy fixes, while others may require professional help. Staying proactive helps prevent small issues from becoming costly repairs.

Common Problems

  • Drafts or Air Leaks: Often due to worn weatherstripping or misaligned doors.
  • Sticking or Swelling: Common with wood doors in humid climates.
  • Squeaky Hinges: Usually caused by a lack of lubrication.
  • Loose Handles or Locks: Hardware may loosen with regular use.
  • Misalignment: Causes uneven gaps or difficulty latching.

Troubleshooting Tips

  • Adjust hinges or strike plates to fix alignment issues.
  • Replace old weatherstripping to block drafts.
  • Use spray lubricant on hinges and locks.
  • Re-tighten or replace screws in handles and locksets.

Call a contractor if the door frame is rotting, the door is sagging, or if locking issues compromise home security.

Frequently Asked Questions

Why is my door suddenly hard to close?

Changes in temperature or humidity can cause wood doors to expand. Check the hinges or sand down swollen areas slightly.


What should I do if my door doesn’t latch properly?

Realign the strike plate or tighten the screws in the door jamb. If the problem persists, consult a professional.


How do I fix a door that’s making noise?

Apply lubricant to hinges and clean any buildup. If the squeaking continues, the hinges may be worn and need replacement.


What to Do After Replacing a Door

After your new door is installed, a few key steps can help ensure everything’s working properly and that your investment lasts. Good follow-up care can also protect warranties and prevent future issues.

Post-Installation Checklist

  • Inspect the Work: Review installation with the contractor. Make sure the door opens, closes, and locks smoothly.
  • Test Hardware: Check that knobs, deadbolts, and any accessories work as expected.
  • Review Warranty: Understand what’s covered, including labor, materials, and finishing, and for how long.
  • Maintain Documentation: Keep receipts, product manuals, and warranty information in a safe place.
  • Plan for Maintenance: Set reminders to inspect weatherstripping, clean hardware, and refinish (if applicable).

You may also want to schedule a follow-up with the contractor after a few weeks to confirm everything has settled and no adjustments are needed.

Frequently Asked Questions

Should I caulk around a newly installed door?

Yes. Proper sealing prevents moisture intrusion and drafts. A professional should complete this during installation, but it’s a good idea to still inspect it afterward.


When can I paint or stain my new door?

Check the manufacturer’s guidelines. Many wood doors require finishing within days of installation to maintain the warranty.


How do I know if the installation was done correctly?

The door should swing freely, latch securely, and have an even reveal (gap) around the edges. There should be no drafts or sticking.


What should I do if I notice issues after installation?

Contact your installer immediately. Many contractors offer a service window during which they’ll return to address any concerns.
