How Installing Energy-Efficient Windows in Estes Park Saves You Money
When you upgrade to energy-efficient windows, you may see a few perks, including:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
- Reduce your carbon footprint: By using less energy after you switch to Energy Star certified windows, you'll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
- Save money on power bills: After you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% since you'll use less energy to heat or cool your house.
Estimated Cost of Window Replacement in Estes Park
Let's go over the cost of installing new windows and the kinds of services offered by installers.
How Much Do New Windows Cost?
According to our research, the national average cost of installing a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. These amounts vary depending on the specifics of your installation, like size, the location of your home, material, number of windows, type and more.
It's also worth noting that energy-efficient windows will cost more upfront, but Energy Star estimates that switching out the windows on your Estes Park 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. The amount of money you'll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Getting free quotes from multiple installers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
The first thing to ask yourself when getting new windows is: Do you need a full-frame installation or a pocket installation?
Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has a great amount of deterioration. Full-frame installations require more time and labor and will increase 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 kind of installment if you have any pre-existing rot or water damage.
If you're hiring a reputable window installation company, your company can recommend the best type for your project. In Estes Park, the choice will mostly depend on how much damage there is currently and the condition of your existing frames.

How We Choose the Best Window Installers in Estes Park
In our search to find the most reliable, eco-friendly window installers in Estes Park, EcoWatch examined many companies before settling on these. Along with energy efficiency, we analyzed several window installers in Estes Park and ranked them based on the following methodology:
Service Area
Because this is a guide for Estes Park, we gave more points to companies that cover the city. There are other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Estes Park.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each company featured in our guide to make sure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If most customers don't have good things to say about their experience with a certain installer, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window companies may not provide the most quality service. On the other hand, we want to make sure we're highlighting companies that provide a variety of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a serious investment, so you'll want to make sure that investment is well protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Estes Park's climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Estes Park window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Estes Park, CO Window Replacement FAQs
What is the average cost to install windows?
The national average cost of installing a single window is around $600 but can range from $200 to $1,200, based on a few different factors. The price is usually dependent on the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the types of windows?
There are several different kinds of windows you can get for your house, including bay windows, picture windows, awning windows, casement windows, slider windows, transom windows and double-hung and single-hung windows.
When do I need to use a window installation company?
Unless you're handy and have all the tools you need to replace your own windows, we recommend hiring a professional installer. The window installation process is complex and can take anywhere from four to six hours for one window. Although it's tempting to try to do it yourself to save money, hiring a company is a faster, more efficient and safer alternative.
How long does it take to install windows?
Since the average installation time is 30 minutes per window, 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 want to get more efficient windows and save money on your energy bills, replacing all of the windows at the same time is the only way to gain that benefit. However, if you have just one or two windows that are damaged or drafty, you can replace just those.
