Why you can trust EcoWatch
A review of the best window replacement companies in Lafayette may not seem like the most interesting article on the EcoWatch site, but trust us, windows have more of an impact on your life than you might realize. If your house has traditional, outdated windows, your HVAC system could be working overtime to heat or cool your house. This means spending more on power bills.
That's also bad news for the environment, as the additional energy used by damaged windows increases your carbon footprint.
Unlike other review sites, EcoWatch ranks window replacement companies based on energy efficiency while also factoring in cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Lafayette Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more details about how upgrading your windows could help you:
- Save on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Switching to energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 460 pounds.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if you have an older home.
Estimated Cost of Window Replacement in Lafayette
Let's take a look at the cost of installing new windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
The typical cost to replace one window is about $600 but can range anywhere from $200 to $1,200. How much it will cost you is based on several factors, including number of windows, type, material, size, the location of your home and more.
It's also worth keeping in mind that energy-efficient windows will usually cost more initially, but Energy Star predicts that switching out the windows on your Lafayette home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
How much your window installation costs will also vary depending on the kind of material you choose for the frames. Wood windows are usually the most expensive, though it depends if they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
The first thing to ask yourself when planning to replace your windows is: Should you get a full-frame installation or a pocket installation?
Full-frame installations involve replacing the complete window, including the frame, trim and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable damage or rot. Because full-frame installations are more involved, they will raise overall costs. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.
Your window installation company should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Lafayette
EcoWatch reviews differ from other reviews, as we examine these companies through a sustainability lens. We've evaluated the top window installation companies in Lafayette primarily based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Lafayette, we only included companies that serve the city. There are other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Lafayette.
Work Quality
When installing new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand you opt for. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including cost, quality of installation, quality of parts, warranty, professionalism and more.
Cost
This one is a give-and-take: similar to most services, cheap window installers may not provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a serious investment, so you'll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Lafayette, CO Window Replacement FAQs
How much does window installation cost?
The typical cost of installing a single window can range from $450 to $650. There are a variety of factors that affect the cost, which include local labor costs, how energy-efficient the windows are, the number of windows, styles and sizes of windows, the materials used in designing the windows and your property's location.
Which type of window is the best?
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 with the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.
Do I really need to use a window installation company?
You should hire a window installation professional whenever you need to replace your windows. Installing windows is a complex process that can take a lot of time, so it's best handled by the professionals.
How long does it generally take to install windows?
Since the average installation time of a window is 30 minutes, about 16 windows can be installed during a typical 8-hour work day.
Should I replace my windows all at the same time?
If you're upgrading your windows to get more efficient windows, replacing all of your windows at once is the only way to see a noticeable difference. However, if you have just one or two windows that are damaged or drafty, you can replace just those.
