How Installing Energy-Efficient Windows in Lone Tree Saves You Money
When you switch to energy-efficient windows, you may see several benefits, such as:
- Save money on power bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of energy use in your home. Upgrading to energy-efficient windows can help reduce that amount, which helps you save $443 a year on your bills.
- 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 Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Lone Tree, that’s about 460 pounds per year on average.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Lone Tree
Windows come in various styles, shapes and purposes, so costs and services will differ tremendously based on your project. Below, we detail the typical cost and services that you can get from window replacement companies.
How Much Do New Windows Cost?
On average, Lone Tree homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at about $600. Costs will differ considerably depending on your location, the quality of your products, the current condition of your home and the number of windows you need. A lot of window companies also offer door installations and other add-ons like shutters, baths, coating and more. Additional services will increase your overall project costs.
Keep in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 per year when replacing single-pane windows and between $27 and $197 per year when installing double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.
Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
There are typically two kinds of window replacement services: full-frame and pocket installations.
Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.
If you’re still debating which type of installation you need, you can ask your installer and get their recommendation. The decision mostly depends on the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in Lone Tree
EcoWatch differs from other reviewers because we assess these companies through a sustainability lens. We’ve assessed the top window replacement companies in Lone Tree primarily based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve Lone Tree so you can find a quality window installation company near you.
Work Quality
When choosing new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand of window you get. We do give window installers more points if they offer high-quality products, but we also factor in 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 experience with a certain installer, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window companies won’t always provide the highest quality service. Still, we want to ensure we’re highlighting companies that provide a spectrum of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important. That’s why window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Lone Tree’s climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Lone Tree window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Lone Tree, CO Window Replacement FAQs
How much should a window install cost?
The average cost of replacing a window ranges from $450 to $650. There are many factors that affect how much it costs, such as styles and sizes of windows, your property’s location, how energy-efficient the windows are, the number of windows, local labor costs and the materials used in designing the windows.
What kind of window is the best for energy efficiency?
A window’s energy efficiency is influenced by a number of 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.
When do I need to use a window installation company?
You should use a window installation professional whenever you want to replace your windows. Installing windows is a complicated process that can be difficult to do on your own, so it’s best handled by the professionals.
When is the best time of year to replace windows?
Replacement windows can be installed at any time, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into your house, so the temperature outside doesn’t necessarily matter that much. Most importantly, the weather should be dry.
Should I replace my windows all at the same time?
If your windows are greater than 20 years old, it’s probably time to replace all of them. By that point, they are typically less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
