How Installing Energy-Efficient Windows in Castle Rock Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here's more information on how upgrading your windows could help you:
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its value.
- Reduce your carbon footprint: By using less energy after switching to energy-efficient windows, you’ll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
- Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Upgrading to energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
Estimated Cost of Window Replacement in Castle Rock
Let’s take a look at the cost of installing new windows and the types of services you may need for your home.
How Much Do New Windows Cost?
Typically, homeowners in Castle Rock can anticipate that most replacement window installations will cost between $250 and $1,200, with the average cost at around $600. This is due to the fact that window installations are based on several factors specific to your home, such as the size, material and number of windows you need to install, as well as the location of your property.
Bear in mind that energy-efficient windows may come at a higher price tag, but Energy Star estimates the upgrade will save you between $101 and $583 per year when replacing single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.
How much your window installation costs will also vary based on the kind of material you choose for the frames. Wood windows are usually the most expensive, although it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
Generally, there are two types of window installation services you can get: full-frame and pocket installations.
Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of rot or deterioration. Full-frame installations are more involved and will increase overall costs. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. But, 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 kind of installation to get, you can talk to your provider and get their recommendation. The decision mostly is influenced by how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in Castle Rock
In our hunt to make your home improvements easier and more eco-friendly in Castle Rock, the EcoWatch Reviews team assessed many companies before landing on these. We have assessed the best window installation companies in Castle Rock primarily based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. 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
This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve Castle Rock so you can find the best window installation company near you.
Work Quality
When it comes to new windows, the quality and range of services can often play just as important of a role in overall efficiency 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 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 nice things to say about their service from a certain window installation company, 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. On the other hand, we want to make sure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Castle Rock’s climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Castle Rock window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Castle Rock, CO Window Replacement FAQs
What is the average cost to replace windows in a home?
The national average cost to replace a single window is about $600 but can range between $200 and $1,200, depending on a variety of factors. The price is often influenced by 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 initially but can save you a decent amount of money a year in energy bills.
What are the different kinds of windows?
The most common types of windows for homes include: picture windows, slider windows, bay windows, transom windows, casement windows, awning windows and double-hung and single-hung windows.
Do you really need to use a window installation company?
You should use a window installation professional whenever you need to replace your windows. Installing windows is a involved process that can take a lot of time, so it’s best left to the professionals.
When is the best time of year to replace windows?
Although you can install windows any time of year, warmer weather is often better for replacing windows. In addition, the weather should be dry, because rain can make the installation more difficult.
Should I replace all my windows at the same time?
If your windows are greater than 20 years old, it’s most likely time to replace all of them. By that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
