How Installing Energy-Efficient Windows in Lone Tree Saves You Money
There are quite a few perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch include the following:
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
- Save on power bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, the switch can help you save around $443 annually on your energy bills in Lone Tree.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
- Decrease your carbon footprint: By using less energy after upgrading to energy-efficient windows, you'll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Lone Tree
Each window installer offers varying services and has different price points based on several factors.
How Much Do New Windows Cost?
Typically, Lone Tree homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at around $600. But costs vary remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations, which have a higher price tag.
It's also worth bearing in mind that energy-efficient windows will usually cost more initially, but Energy Star estimates that upgrading the windows on your Lone Tree home translates to an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you'll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Requesting free quotes from several installers is the best way to figure out which one is right for you.
What Services do Window Installers Offer?
The first thing to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?
Full-frame installations involve replacing the total 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 considerable rot or deterioration. Full-frame installations are more involved and will raise the overall cost. A pocket installation entails replacing a window without replacing the frame. This means instead of taking out the whole window and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company will be able to recommend the best type for your project. In Lone Tree, the decision will mostly be influenced by how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in Lone Tree
In our search to make your home improvements easier and more eco-friendly in Lone Tree, the EcoWatch Reviews team assessed many companies before landing on these. We've reviewed the top window replacement companies in Lone Tree mostly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Since this is a guide for Lone Tree, we gave more points to companies that cover the city. There are other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Lone Tree.
Work Quality
We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each installer included in our guide to ensure its contractors are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have positive feedback about their experience with a certain window installation company, you won't see it featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Lone Tree's climate, homeowners need to be wary of low efficiency, rot 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
What is the typical cost to install new windows?
The typical cost to install a single window ranges from $450 to $650. There are a variety of factors that influence how much it costs, which include your property's location, how energy-efficient the windows are, styles and sizes of windows, the materials used in designing the windows, the number of windows and local labor costs.
What are the most common types of replacement windows?
The most common kinds of windows for homes include: picture windows, casement windows, slider windows, transom windows, double-hung and single-hung windows, bay windows and awning windows.
When do I need to use a window installation company?
You should use a window installation professional whenever you want to upgrade your windows. Installing windows is a complex process that can be difficult and time-consuming, so it's best left to 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 home, so the temperature outside isn't necessarily a big factor. What's most important is that the weather should be dry.
How do you know it's time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to operate, they may be in need of replacement.
