Your exterior doors play an important role in your home’s security, energy efficiency, curb appeal, and everyday comfort. When it is time to replace an entry door, patio door, or sliding glass door, you need more than a salesperson pushing one product line. Reflection Windows & Doors has served Denver homeowners since 1993 with a simple approach: recommend the right door solution for your home, not the option that creates the biggest sale.
With access to leading manufacturers and decades of experience installing exterior doors throughout the Denver metro area, our team helps homeowners choose doors that match their home’s architecture, performance goals, and budget. Whether you need a front entry door replacement, a new patio door, or a sliding glass door upgrade, Reflection Windows & Doors provides honest recommendations and professional installation from start to finish.
Many door companies only sell products from one manufacturer. Reflection Windows & Doors takes a different approach by offering access to multiple trusted brands, allowing our team to recommend the right door based on your home’s needs rather than a limited inventory.
Our multi-brand selection includes options from manufacturers such as Pella, Andersen, Milgard, Weather Shield, Western Window Systems, Simonton, and other trusted names in the industry.This flexibility allows homeowners to compare materials, designs, energy performance, security features, and price points before making a decision.
Our “Do the Right Thing” philosophy guides every exterior door project. If your existing door can be repaired or adjusted instead of replaced, we will tell you. If replacement is the better long-term solution, we explain why and help you choose an option that fits your home. The goal is not to sell you the most expensive door. The goal is to provide a door solution that makes sense for your property.
Reflection Windows & Doors maintains BBB A+ rating status and holds HomeAdvisor Elite Services and Screened and Approved designations, giving Denver homeowners independent verification of professional standards and customer service. The 2026 Workplace Safety PCC Certification also reflects our commitment to safe and professional job sites.

Colorado weather creates unique challenges for exterior doors. Temperature swings, intense sunlight, winter conditions, and seasonal moisture can affect door seals, hardware, glass, and overall performance over time. While some issues can be repaired, there are situations where replacing your exterior doors provides better comfort, security, and long-term value.
Common signs your exterior doors may need replacement include:
Not every door issue requires a complete replacement. Part of our process is evaluating the condition of your existing door and explaining your options. In some cases, repairs or hardware adjustments may solve the problem. In others, a new entry door, patio door, or sliding glass door replacement may provide the best long-term solution.
Guided by the principle "Do the Right Thing," our seasoned experts provide industry-leading expertise.
With a Can Do Attitude, we deliver premium materials and craftsmanship for lasting home improvement solutions.
Superior customer care and support, making your experience with us truly exceptional.
Your front entry door is one of the first things people notice about your home, but it also serves as an important barrier against Colorado weather and unwanted access. Modern entry doors offer improved insulation, stronger materials, updated locking systems, and a wide range of design options.
Reflection Windows & Doors installs entry doors in a variety of styles, materials, and configurations to complement Denver homes of all types. From traditional neighborhoods with older architecture to newer communities throughout the metro area, our team helps homeowners select entry doors that balance appearance, durability, and performance.
Available entry door options may include:
Patio doors connect your indoor and outdoor spaces while providing natural light and easy access to decks, patios, and outdoor living areas. An outdated patio door can create drafts, stick when opening, or reduce your home’s overall energy efficiency.
Reflection Windows & Doors installs patio doors designed for smooth operation, improved insulation, and long-term reliability. Our team helps you compare available options based on your home’s layout, usage needs, and performance goals.
Patio door options include:
Sliding glass doors are popular throughout Denver because they provide natural light, outdoor views, and convenient access to patios and yards. Over time, rollers can wear down, seals can fail, and older glass systems may become less efficient.
Replacing an outdated sliding glass door can improve comfort, security, and everyday operation. Reflection Windows & Doors helps homeowners select sliding door systems that provide smooth movement, reliable locking systems, and improved energy performance.
Modern sliding glass doors may include:
Exterior door performance depends on more than the door itself. The frame, glass package, weatherstripping, and installation quality all impact insulation and comfort.
Modern patio doors and sliding glass doors often include insulated glass units with low-emissivity coatings designed to reduce heat transfer while allowing natural light into your home. Double-pane glass is common for many replacement projects, while homeowners seeking additional efficiency may consider upgraded glass packages.
Entry doors also benefit from insulated cores, quality weather seals, and properly installed frames. During your estimate, our team explains available options and helps you understand what features provide real value for your specific home.
The right exterior door should help reduce drafts, improve comfort near door openings, and perform reliably through Denver’s seasonal temperature changes.
Replacing outdated exterior doors with qualifying energy-efficient products may help homeowners access available incentives. Denver homeowners may qualify for federal tax credits through the Energy Efficient Home Improvement Credit when installing eligible energy-efficient exterior doors. Xcel Energy may also offer rebate programs for certain qualifying home improvements.
Program requirements, qualifying products, and available incentives can change over time. Reflection Windows & Doors helps homeowners understand potential rebate opportunities during the estimate process so you have a clearer picture of your total investment.
Our door and window rebates guide provides additional information about available programs and requirements.
Replacing an exterior door should be a straightforward experience. Reflection Windows & Doors follows a clear process designed to provide honest recommendations and quality installation from the first consultation through project completion.
The process begins with a free in-home estimate. A member of our team evaluates your existing doors, discusses your goals, reviews available options, and provides a written recommendation based on your home’s needs. There is no pressure to make a decision immediately.
Once you select your door system, our team coordinates ordering, scheduling, and installation details. Lead times vary based on the manufacturer, product selection, and customization options. We provide realistic expectations upfront so you know what to expect.
During installation, our team protects your home, maintains a clean work area, and ensures the new door operates properly before completing the project. We review operation, maintenance recommendations, and warranty information after installation is complete.
Reflection Windows & Doors provides exterior door replacement throughout the Denver metro area, including Denver, Arvada, Aurora, Centennial, Cherry Creek, Cherry Hills Village, Englewood, Greenwood Village, Highlands Ranch, Lakewood, Littleton, Westminster, Broomfield, Thornton, Longmont, Castle Rock, Commerce City, Wheat Ridge, Golden, Parker, and surrounding communities.
From front entry doors in established Denver neighborhoods to patio and sliding glass door replacements in newer suburban homes, the same experienced team and “Do the Right Thing” approach applies to every project.
If you are unsure whether your exterior doors need repair or replacement, our team can evaluate your current system and provide an honest recommendation. You can also explore our glass replacement service if your issue may involve only the glass unit, or our window replacement service page if your project includes both windows and doors.
Many door problems can be repaired, but some issues indicate that replacement is the better long-term option. If the door frame is structurally sound and the issue involves hardware, weatherstripping, or minor adjustments, repairs may solve the problem. If the door is warped, damaged, outdated, or no longer provides proper insulation, replacement may provide better performance. Reflection Windows & Doors evaluates your specific situation and recommends the option that makes the most sense for your home.
Reflection Windows & Doors installs a variety of exterior door systems, including entry doors, patio doors, French doors, and sliding glass doors. Our team works with multiple manufacturers, including Pella, Andersen, Milgard, Weather Shield, Western Window Systems, Simonton, and additional brands. This allows us to recommend products based on your home's design, performance goals, and budget rather than limiting you to one manufacturer.
