20 Best Window Companies in Lone Tree, CO (2025 Reviews)

How Installing Energy-Efficient Windows in Lone Tree Saves You Money

By switching to energy-efficient windows, you and your family can benefit in several ways, including:

• 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• Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.
• 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 from fading: The low-emissivity coatings on some energy-efficient windows 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 different shapes and sizes, so costs and services will differ greatly. Here are the typical costs and the primary services that you can find from the average window installation company.

How Much Do New Windows Cost?

Generally, homeowners in Lone Tree can anticipate that most window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. But costs differ considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations, which will add extra costs to your project.

It’s important to keep in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars by lowering your energy bills. Investing in certified energy-efficient windows can save Lone Tree homeowners $443+ a year when replacing single-pane windows.

We recommend requesting free quotes from several window companies to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

When it comes to window replacements, there are generally two kinds that your installer will have: 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 significant deterioration. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation entails replacing a window without removing the entire frame, which tends to be cheaper than a full-frame installation.

Your window installation company will be able to recommend the best type for your project. In Lone Tree, the choice will mostly be influenced by how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Lone Tree

In our hunt to find the most reliable, eco-friendly window installers in Lone Tree, the EcoWatch Reviews team assessed dozens of companies before deciding on these. Along with energy efficiency, we reviewed each installer and ranked them using the following methodology:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

When picking new windows, the quality and range 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 give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent online reviews to find the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including warranty, quality of parts, cost, quality of installation, professionalism and more.

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 offer 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 be certain that investment is well protected. 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 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.
