How Installing Energy-Efficient Windows in Genesee Saves You Money
There are several perks of switching to energy-efficient windows. Some reasons you may want to consider making the switch are the following:
- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
- Save on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of household energy use. Switching to energy-efficient windows can help decrease that number, which helps you save $443 a year on your bills.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Decrease your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by about 460 pounds.
Estimated Cost of Window Replacement in Genesee
Each window installer offers varying services and has varying price points based on several factors.
How Much Do New Windows Cost?
Generally, Genesee homeowners can anticipate their window installations to range from $250 to $1,200. The most common installations sit at around $600. These numbers are based on specific characteristics of your installation, such as type, material, size, the location of your home, number of windows and more.
It's important to note that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Genesee homeowners $443+ a year when replacing single-pane windows.
The cost of your window installation will also vary depending on the kind of window material you choose for the frames. Wood windows are typically the most expensive, though it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
The first thing to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?
Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has a great amount of damage. Full-frame installations involve more time and labor and will increase overall costs. A pocket installation involves replacing a window within the old frame. So, instead of taking out the whole window and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you're unsure which kind of window installation service you should get, your installer can help you out. Generally, the choice is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Genesee
In our hunt to find the most reliable, eco-friendly window installers in Genesee, the EcoWatch team evaluated dozens of companies before landing on these. Along with energy efficiency, we analyzed each installer and assigned rankings using the following methodology:
Service Area
Because this is a guide for Genesee, we paid more attention to companies that serve the city. There are other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Genesee.
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 rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have positive feedback about their service from a certain company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window companies are not going to provide the highest quality service. Still, we want to ensure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a sizable 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 Genesee's climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of Genesee window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Genesee, CO Window Replacement FAQs
How much does a window install cost?
The national average cost to install one window is about $600 but can range between $200 and $1,200, depending on a variety of factors. The price is usually dependent on the size of the window, the location of your property and the type and material of the window. Also, keep in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What are the most common kinds of replacement windows?
There are several different types of windows you can get for your house, including casement windows, transom windows, bay windows, double-hung and single-hung windows, picture windows, slider windows and awning windows.
What do window installation companies do?
Window installation companies will do the entire process — from replacing old windows with new ones to cleaning up after the windows have been put in place. Additionally, some companies offer window manufacturing, customization and repairs.
How long does it generally take to install windows?
Each window takes about 30 minutes to install based on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
When is the best time of year to replace windows?
Replacement windows can be installed during any season, but autumn might be best. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into the house, so the temperature outside doesn't necessarily matter that much. What's most important is that the weather should be dry.
