How Installing Energy-Efficient Windows in Fort Lupton Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here's more information on how switching out your windows could help you:
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Upgrading to energy-efficient models can help decrease how much you have to pay, therefore saving you about 12% more on your bills.
- Decrease your carbon footprint: In Fort Lupton, you can lower your indirect greenhouse gas emissions by about 460 pounds per year when you switch to energy-efficient windows.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, especially if you have an older home.
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.
Estimated Cost of Window Replacement in Fort Lupton
Windows come in various styles, purposes and shapes, so costs and services will vary greatly depending on your project. Below, we detail the typical cost and services that you can get from window installers.
How Much Do New Windows Cost?
On average, Fort Lupton homeowners can anticipate their replacement window installations to range from $250 to $1,200. The average cost is at about $600. But prices vary considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door replacements, which will add extra costs to your project.
Whether or not you want energy-efficient windows is another factor that will determine the cost. These will typically cost more than other windows, but on the other hand, you can save about $457 a year on your energy bills in Fort Lupton.
Another factor that influences the overall cost is the material of the frame you pick. Aluminum frames are generally the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
When considering window replacements, there are typically two types that your provider will offer: full-frame and pocket installations.
Full-frame installations are usually done when you want a new style or your window has significant rot or deterioration. With this service, your installers will replace the total window, including the trim, frame and sill. Pocket installations are simpler and won't cost as much, as they involve simply replacing the window within its existing frame. But if the frame has any damage, you may have to get a full-frame installation instead.
If you're hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Fort Lupton, the decision will mostly be influenced by how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in Fort Lupton
EcoWatch reviews differ from most reviews, as we assess these companies through a sustainability lens. We've reviewed the top window installation companies in Fort Lupton mostly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Because this is a guide for Fort Lupton, we paid more attention to companies that cover the city. There are certainly other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Fort Lupton.
Work Quality
When choosing new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent online reviews to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including professionalism, quality of installation, cost, quality of parts, warranty and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing providers' prices, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Fort Lupton's climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Fort Lupton window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Fort Lupton, CO Window Replacement FAQs
How much does window installation cost?
The national average cost to replace a window is about $600 but can range from $200 to $1,200, depending on a variety of factors. The price is typically influenced by the type and material of the window, the size of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
Which kind of window should I get?
Generally, double-pane windows are more efficient than single-pane windows and windows that don't open are more efficient than windows that do. If you want to be sure you'll get the most energy-efficient windows, look for models that have the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.
What do window installation companies do?
Window installers will do the entire process — from replacing old windows with new ones to cleaning up afterward. Additionally, some companies offer window manufacturing, customization and repairs.
What time of year is the best time to replace my windows?
Replacement windows can be installed during any season, but autumn might be best. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into the home, so the temperature outside isn't necessarily a big factor. Most importantly, the weather should be dry.
Should I replace all my windows at the same time?
If you want to get more efficient windows and save money on your energy bills, replacing all of the windows together is the only way to see a noticeable difference. On the other hand, if you have just one or two windows that are broken or drafty, you can replace just those.
