Understanding Replacement Doors and Windows

When it comes to contractor replacement doors and windows, understanding the basics can help you make informed decisions. Let’s break down the types of windows and doors, materials, and energy efficiency features.

Types of Windows

  1. Awning Windows: Hinged at the top and open outward. Great for ventilation, even during light rain.
  2. Bay & Bow Windows: Extend outward from the home, creating more interior space and offering panoramic views.
  3. Casement Windows: Hinged on the side and open outward like a door. They provide excellent ventilation and a clear view.
  4. Double- & Single-Hung Windows: Feature two sashes in a single frame that slide vertically. Double-hung windows allow both sashes to move, while single-hung only allows the bottom sash to move.
  5. Gliding Windows: Slide horizontally along a track. Ideal for spaces where you don’t want a window to protrude.
  6. Picture Windows: Fixed windows that don’t open, perfect for letting in natural light and capturing views.
  7. Specialty Windows: Custom shapes and sizes for unique architectural needs.

Types of Doors

  1. Entry Doors: The main door that provides access to your home. Available in various materials like wood, fiberglass, and steel.
  2. Patio Doors: Usually sliding or French doors that lead to outdoor spaces. They can feature large glass panels to maximize light.
  3. Storm Doors: Installed in front of an exterior door to protect it from bad weather and provide additional insulation.
  4. Screen Doors: Allow for ventilation while keeping insects out. Often used in conjunction with entry or patio doors.


The materials used in contractor replacement doors and windows significantly impact their durability, maintenance, and energy efficiency.

  • Wood: Offers natural beauty and excellent insulation. Requires regular maintenance to prevent rot and warping.
  • Vinyl: Affordable and low-maintenance. Provides good insulation but can expand and contract with temperature changes.
  • Fiberglass: Highly durable and low-maintenance. Resistant to warping and has excellent thermal properties.
  • Aluminum: Strong and lightweight. Best for large windows and doors, but less insulating than other materials unless thermally broken.

Energy Efficiency

Energy efficiency is crucial when selecting replacement doors and windows. Efficient windows and doors can reduce your energy bills and improve your home’s comfort.

  • Low-E Coatings: Thin metallic layers applied to the glass that reflect heat while allowing light to pass through. Keeps your home warm in winter and cool in summer.
  • Gas Fills: Argon or krypton gas between panes of glass provides better insulation than air.
  • Multiple Panes: Double or triple-pane windows offer better insulation and noise reduction compared to single-pane windows.
  • Frame Materials: As mentioned, materials like fiberglass and vinyl provide better insulation than aluminum without thermal breaks.

Energy Efficient Windows - contractor replacement doors and windows

Energy Star and the National Fenestration Rating Council (NFRC) certify windows based on their performance in different climate zones. Look for their labels to ensure you’re choosing the best options for your region.

By understanding these basics, you can confidently discuss your needs with a contractor and make choices that enhance your home’s energy efficiency, appearance, and comfort.

Next, we’ll dive into how to choose the right contractor for your replacement doors and windows, ensuring a smooth and successful project.

How to Choose the Right Contractor

Choosing the right contractor for replacement doors and windows is crucial to ensure a smooth and successful project. Here are some essential factors to consider:


First, ensure the contractor has the proper credentials and certifications. This includes:

  • Factory-Trained Installers: Contractors who have received specialized training from the manufacturers of the windows and doors they install. This ensures they know the best practices for installation.
  • Industry Certifications: Look for certifications from reputable industry organizations. For example, AAMA Installation Certification is a recognized standard in the industry.
  • BBB Accreditation: A Better Business Bureau (BBB) accreditation signifies that the contractor meets high standards of trust and customer service.


Experience matters when it comes to installing replacement doors and windows. Look for contractors with:

  • Years in Business: A contractor with several years of experience is likely to have a proven track record.
  • Portfolio of Past Projects: Ask to see examples of their previous work. This can give you an idea of their expertise and quality of work.
  • Specialization: Ensure they specialize in the type of windows and doors you need. Some contractors may be experts in residential projects, while others focus on commercial installations.


Customer feedback can provide valuable insights into a contractor’s reliability and quality of work. Here’s how to use reviews to your advantage:

  • Google Reviews: Check the contractor’s Google reviews for a broad perspective on customer satisfaction. Look for consistent patterns in the feedback.
  • HomeAdvisor: This platform offers verified reviews from homeowners, which can be particularly useful for understanding the contractor’s strengths and weaknesses.
  • Word of Mouth: Personal recommendations from friends, family, or neighbors can be incredibly reliable. They offer first-hand accounts of the contractor’s work and customer service.

Local Expertise

Choosing a local contractor has several benefits:

  • Knowledge of Local Building Codes: Local contractors are familiar with the building codes and regulations in your area, ensuring compliance and avoiding potential issues.
  • Quick Response Time: A local contractor can respond more quickly to any issues or concerns that arise during or after the installation.
  • Community Reputation: Local contractors rely on their reputation within the community. They are more likely to provide excellent service to maintain their standing.

By considering these factors, you can find a reliable and qualified contractor for your replacement doors and windows project. Next, we’ll explore the top tips for hiring contractors to ensure you make the best choice for your home.

Contractor Replacement Doors and Windows: What to Expect

When you hire a contractor for replacement doors and windows, knowing what to expect can make the process smooth and stress-free. Here’s a breakdown of the process, timeline, costs, and warranties involved.


  1. Initial Consultation: The contractor visits your home to inspect your current windows and doors. They discuss your needs, preferences, and provide recommendations.
  2. Measurements: Accurate measurements are crucial. The contractor measures the width and height of your windows and doors, noting any unique features.
  3. Product Selection: You’ll choose the materials and styles for your new windows and doors. Options include natural wood interiors with aluminum or fiberglass exteriors for durability.
  4. Quote and Agreement: The contractor provides a detailed quote. This can be a binding quote, which is a fixed price, or an estimated quote, which may change based on unexpected issues.
  5. Permits and Ordering: The contractor handles any necessary permits and orders your windows and doors.
  6. Installation: The team removes old windows and doors, addresses any structural issues, and installs the new ones. They ensure everything is properly sealed and functional.
  7. Final Inspection: After installation, the contractor conducts a final inspection to ensure everything meets your expectations.


The timeline for replacing windows and doors typically ranges from four to 15 weeks from initial consultation to completion. Here’s a rough breakdown:

  • Consultation and Measurements: 1-2 weeks
  • Product Ordering: 2-6 weeks (depends on customizations and supplier schedules)
  • Installation: 1-2 days per window/door, with the entire project taking up to a week for a full house


The cost varies based on several factors:

  • Materials: Wood, aluminum, and fiberglass have different price points. For instance, extruded aluminum and fiberglass are more durable but also more expensive than vinyl.
  • Labor: Professional installation ensures quality and longevity but adds to the cost.
  • Customization: Custom sizes, shapes, and finishes increase the price.

On average, replacing windows can cost anywhere from $300 to $1,500 per window, while doors range from $500 to $5,000 depending on the complexity and materials.


A reliable contractor will offer warranties on both materials and labor. Here’s what to look for:

  • Material Warranty: This covers defects in the windows and doors themselves. For example, Marvin windows come with robust warranties due to their high-quality materials like extruded aluminum and fiberglass.
  • Labor Warranty: This covers issues arising from the installation process. A good contractor will stand by their work and provide a warranty period during which they will address any problems.

By understanding these aspects, you can confidently navigate the process of hiring a contractor for your replacement doors and windows project. Next, we’ll explore the top tips for hiring contractors to ensure you make the best choice for your home.

Frequently Asked Questions about Contractor Replacement Doors and Windows

How much does it cost to have windows and doors replaced?

The cost of replacing windows and doors can vary widely. On average, replacing all the windows in a 2,000-square-foot home ranges from $5,000 to $10,000. Several factors influence this price:

  • Materials: The type of materials used (vinyl, wood, aluminum) can significantly impact the cost.
  • Window Style: Different styles, like bay windows or double-hung windows, come at different price points.
  • Labor Costs: Local labor rates and the complexity of the installation can also affect the final price.
  • Number of Windows and Doors: Naturally, the more units you need to replace, the higher the overall cost.

A detailed quote from a reliable contractor will break down these costs, helping you understand where your money is going.

Can I install my own windows and doors?

You can save about 15% of the cost of a window replacement if you decide to replace the windows yourself. However, window replacements can be tricky, especially if the windows are very large, high, heavy, irregularly shaped, or in hard-to-reach areas. So unless you feel very comfortable performing a window replacement, it’s typically best to hire a professional for this job.

“Measuring for replacement windows and the installation can be tricky if you’ve never done it before. We always recommend hiring a contractor with experience in window replacements or having the company you are purchasing from take the measurements and perform the install. While you may be able to save some money with DIY, the wrong measurements or incorrect installation can be extremely costly.” – Derek Walczak

What do you call someone who fits windows and doors?

A professional who installs windows and doors is often referred to as a glazier or an installer.

  • Glazier: A glazier specializes in working with glass. They are skilled in cutting, installing, and removing glass, making them ideal for window installations.
  • Installer: An installer may handle a broader range of tasks, including fitting doors and windows, and ensuring that they are properly sealed and secure.
