How Installing Energy-Efficient Windows in Laramie Saves You Money
Energy-efficient windows can offer benefits in more than one way. Here are some reasons you may want to consider making the switch:
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- Decrease your carbon footprint: In Laramie, you can reduce your indirect greenhouse gas emissions by about 1261 pounds per year once you upgrade to energy-efficient windows.
- Save money on power bills: Once you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll need less energy to heat or cool your house.
- Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Laramie
When considering window installation, each company provides different services and costs. Let’s take a look at some average costs and services.
How Much Do New Windows Cost?
The average cost to install a single window is about $600 but can range anywhere from $200 to $1,200. This is because window installations are based on several factors specific to your home, like the size, material and number of windows you need to replace, as well as where your property is located.
With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — especially during the winter — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Laramie homeowners $500+ per year after replacing single-pane windows.
Requesting free quotes from multiple installers is the best way to figure out which one will work best for your budget.
What Services do Window Installers Offer?
There are typically two kinds of window installation services: full-frame and pocket installations.
Full-frame installations involve replacing the complete window, including the trim, frame and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has noticeable rot. Because these installations are more involved, they will increase the overall cost. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations more simple and affordable. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
If you’re still trying to decide which type of installation you should get, you can talk to your provider and get their advice. The decision mostly is influenced by the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Laramie
In our search to find the most reliable, eco-friendly window installers in Laramie, the EcoWatch team examined many companies before deciding on these. Along with energy efficiency, we analyzed several window installers in Laramie and ranked them using the following methodology:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve Laramie so you can find the right window installation company near you.
Work Quality
When picking new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand of window 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
We analyzed trends in recent customer feedback to determine the companies with the highest rates of customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including quality of parts, cost, professionalism, quality of installation, warranty and more.
Cost
This one is a give-and-take: as with other services, cheap window installation companies may not provide the most quality service. Still, we want to make sure we’re highlighting companies that provide a range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed previously, windows are a considerable investment, so you’ll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for a while. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Laramie, WY Window Replacement FAQs
What is the average cost to replace windows?
The national average cost to install one window is around $600 but can range from $200 to $1,200, based on several factors. The price is often 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 a decent amount of money a year in energy bills.
What kind of window is the most energy-efficient?
A window’s energy efficiency is affected by several factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are usually the most energy-efficient and are certified by the U.S. Department of Energy.
What do window installers do?
Window installation professionals visit your home to remove your old windows and replace them with new ones. Some providers install products distributed by other companies, whereas others install their own windows. The installer will also clean up after the installation.
Should I replace all my windows at once?
If you’re upgrading your windows to save on your energy bills, replacing all your windows together is the only way to see a noticeable difference. However, if you have only one or two windows that are broken or leaky, you can replace just those.
