The Ultimate Guide to window replacement

When it comes to home improvement projects, few are as rewarding as window replacement. Not only does it add value to your home, but it can also improve its energy efficiency and curb appeal. But before you start shopping for new windows, it’s important to understand what you’re looking for and what your options are. If you’re considering window replacement, there are a few things you should keep in mind.

When To Replace Windows

Windows are a significant investment that adds value to your home. However, they do have a limited lifespan and can start to lose their value over time. While it’s not possible to predict exactly when this will happen, you can spot signs of wear and tear that may indicate the need for window replacement sooner rather than later.


While there are many reasons you might want to replace your windows, the most common one is that they’re too drafty or leaky. Drafting can cause a house to feel cold in the winter and hot in the summer, so it’s important to make sure that any new window is properly insulated. Leaky windows can be a nuisance as well as a safety hazard because they let in moisture that can rot wood framing. Replacing them can also save you money in the long run because you’ll likely be paying less each year for energy bills.


Another reason to consider window replacement is if they’re severely damaged. Even though they may have been repaired previously, it’s best to take them off of the market until you know exactly what needs to be done with them. You should also consider replacing them if you bought an older home with older windows, which may not have been well built or maintained over time.


You may want to ask: Can’t I just repair my windows? The short answer is yes, but it’s not very likely. To repair them, you’d need to have the windows from your current company already installed in your home. Other companies, on the other hand, would probably require full replacement if you don’t already have them. In most situations, replacing your windows would be the best option.

Energy Efficient Windows

Homeowners are always looking for ways to reduce their energy bills, and one of the most effective ways to do this is to install energy efficient windows. These windows are designed to minimize heat loss in the winter and keep your home cooler in the summer, and they can also help to block out noise pollution. In addition, energy efficient windows can improve the resale value of your home and make it more comfortable to live in.


The most common types of energy efficient windows are low-E glass and argon gas filled glass. Low-E glass is made from a special type of glass that blocks out more heat than regular glass. Argon gas filled glass is filled with argon gas which helps absorb and block heat from entering a home. Both of these types of glass allow light to pass through so they provide plenty of natural light while still keeping heat out.


An important factor to consider when choosing an energy efficient window is the amount of sunlight that comes through it. If you have a large overhang or a lot of glass panes to cover, you’re likely to see more heat loss and need thicker window glass. On the other hand, if you have limited sun exposure, opt for a translucent or semi-transparent window with small panes that block less sunlight. 


Make sure to select quality replacement windows that have been ENERGY STAR certified. These products have been independently verified to meet strict energy efficiency standards, and they can help you save money on your energy bills for years to come. On average, residents of Colorado can see annual savings of up to 22% on their hearing and cooling (Source: Benefits Of Energy Star Qualified Windows)

Window Replacement Styles

Insert vs. Full Frame

One important decision is whether to opt for insert windows or full frame windows. Insert windows are designed to fit into the existing frames of your current windows, while full frame windows require the entire window to be replaced. 


If your current windows are in good condition and you just want to update the glass, insert windows may be the way to go. However, if your window frames are damaged or poorly insulated, full frame windows will provide a better seal and help to improve energy efficiency. Ultimately, the best choice depends on the condition of your current windows and your specific needs.

Window Style Options

There are so many different types of window replacement styles to choose from. For example, if you’re looking for a classic look and want your new window to match the rest of your home’s design, then traditional windows might be a good choice.However, if you’re looking for a modern look and want your replacement window to stand out from the crowd, then casement or double-hung windows could be the better choice.


In all these cases, there are pros and cons to consider. One of the most appealing features of a replacement window is its style – so choose carefully based on your preferences and needs.

Double Hung Replacement Window

The height of durability, these classic window settings are the most popular window fashion for a reason. With endless versatility for design and ease-of-use, double-hung windows have upper and lower sashes enclosed in a single window casing. This allows both panes to slide smoothly within the casing for adjustable draft control.

When you are looking for traditional yet versatile window replacements that are easy to maintain, glider windows are your dream come true. This window style brings the true elegance of simplicity to your home with two large panes nestled in a frame that sits flush to the exterior and gently accentuates all of the beauty of the outdoors. They can be installed to open vertically or horizontally depending on your preference, making them perfect for any home.

Casement windows are the style that withstands the test of time. As one of the earliest designs for windows with a range of motion, this window has remained one of the most popular designs on the market. A single large pane nestled in a hinged frame allows for an unobstructed view and ample light to filter in. A classic hand crank supports easy open and closure movements with minimal effort.

Very similar to casement windows, awning windows are the perfect meld of form and function. This window style is incredibly popular in bathrooms and basement areas, where both light and ventilation are a necessity. The top hinge mechanism allows these spatially conscious windows to open from the bottom, which means they can be installed higher up than most window configurations. This gives you security and privacy as well as easy ventilation for your space.


Are you looking for that wow-factor for your home? Bow windows provide an air of sophistication to any space. The bow window design is comprised of four to six window panes in a curved configuration. This window setting will not only accentuate the architectural aspects of your home, but also open up your interior space and give you room for a sun area or a comfortable window seat!


When it comes to finding a window that will act more as a focal point for your home’s design, bay windows are the perfect solution. A large picture window framed by two smaller windows is set in a shelf-style frame that protrudes outward from the home. This window design opens up your space, letting in abundant amounts of natural light and adding a touch of drama to your home’s already-impeccable facade.


Selecting The Right Material

The most popular replacement window materials are wood, vinyl, aluminum, and fiberglass . Each one has its own pros and cons so choose based on what’s important to you. For example ,wooden frames are very strong but require more maintenance than vinyl or fiberglass .Vinyl frames are less expensive than wood but not as strong. Fiberglass is somewhere in between wood and vinyl in terms of price and strength.

Wood and Wood-Clad Windows

Wooden windows are a classic style that adds character to your home. They are also fairly durable and easy to repair or replace if damaged. Wooden windows, however, are not as energy-efficient as some other materials, and they may be more costly to install. Despite their gorgeous appearance, wooden windows require a lot of care. Wood is used on the inside of wood-clad windows, while vinyl or aluminum is used on the outside. This gives the windows a warm, attractive appearance while boosting their weather resistance.

Vinyl Windows

If you’re looking for a low-maintenance way to keep your home protected from the elements, vinyl windows could be a good option. They are easy to clean, which means they don’t need much maintenance or upkeep. And, they also come in a wide range of styles and colors. So, you can find one that will fit your home and style perfectly.


Vinyl windows also have their benefits when it comes to energy efficiency. They are able to insulate against cold weather very well, which helps keep your home warm during winter months. And, they are also very durable so they can withstand hail storms and other weather-related damage.

Aluminum Windows

Aluminum windows are easy to keep clean and rust-free, but they can be more expensive than other materials and may not provide as much insulation as you want. They are also low maintenance, which makes them a popular choice. Corrosion can sometimes result from aluminium’s susceptibility to it, which may cause mold.

Fiberglass Windows

Fiberglass windows can withstand up to four times the impact of traditional windows. And because they don’t corrode or rot, fiberglass windows can provide years of trouble-free service. In addition, fiberglass windows are also energy efficient. They have a low thermal conductivity, which means they help to keep heat inside your home during the winter and out during the summer. As a result, fiberglass windows can help to reduce your energy bills.

Top Rated Window Companies

Brand differences among window companies can make a big difference. There are many window replacemement manufacturers to choose from so it’s important to select the right brand. The benefits of going with a reputable company include assured quality, solid warranties, experienced professionals, and better customer service.

High-Altitude Windows

Colorado’s abundance of sunshine, extreme weather patterns, and sudden changes in temperature are tough on windows.  When living in higher elevation regions, it’s important to have windows that can withstand the cold. High-altitude windows are excellent replacement windows for homes in cold climates because they specially designed to block heat loss.


These windows usually have multiple panes of glass, which makes a barrier against the cold air outside. In addition, high-altitude windows are usually equipped with special coatings that reflect heat back into the room. As a result, they can help to keep your house warm and cozy all winter long in colder regions.


Because only 1% of the country is above 5,000 feet, most manufacturers don’t employ high-altitude glass. The majority of manufacturing units for windows are located at lower elevations. Even if windows and seals make it to a high-altitude home for installation, they may warp and be compromised before ever reaching their destination. It’s important to work with a window replacement company that is experienced with high-altitude glass.

Professional Window Installation

Replacing the windows in your home is a big project that should be handled by professionals. There are several benefits of hiring professionals for window installation. First, they have experience working with larger projects and can complete them faster than homeowners can.Second, they use the best tools and materials to ensure that your windows last longer. Finally, they have better safety training and know how to prevent accidents from happening.


It’s also important to manage your risks. Every homeowner who replaces a window on their own must go through the manufacturer’s installation process. If the manufacturer detects that you installed your window improperly, they may deny the window’s warranty. They will conclude that the window was installed improperly and you will be responsible. Make sure your investment is protected by only working with a trusted window replacement company that offers a lifetime installation warranty.

Cleaning And Maintenance

Like any other building material, windows need to be cleaned and maintained regularly to ensure they continue to perform at their best. Regularly wiping down your windows with a damp cloth will help remove any dust, dirt or grime that collects on the surface and also helps keep them clearer for longer. In addition, regular cleaning will also help avoid any build-up of algae that can lead to discoloration and damage to your window frame. It’s important to do to make sure they last past their warranty.

Low-E glass is a term used to describe any type of glass that has been coated with an anti-glare coating. Low-E refers to the low emission of ultraviolet light by the glass, while E means “emitting” UV light.


Low-e glass is a good option if you want to reduce the amount of heat entering your home or office during the summer months. It’s also a good choice if you have an open floor plan or large windows that let in a lot of sunlight.

To receive an AAMA Window Certification, a window must pass three tests to ensure its structural integrity. These tests include water leakage, air leakage, and structural strength. Whenever a window has been labelled, you may know that it has been certified by the AAMA. AAMA certified windows are only made by a few window manufacturers and are usually only offered in the form of energy efficiency ratings like U-Factor and Solar Heat Gain Coefficient.
