How Installing Energy-Efficient Windows in Parker Saves You Money
By switching to energy-efficient windows, you can benefit in several ways, such as:
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Parker, that’s about 460 pounds per year on average.
- Save money on power bills: Once you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll require 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 increase the value of your house if you decide to sell.
Estimated Cost of Window Replacement in Parker
Each window installation company offers varying services and has varying price points based on several factors.
How Much Do New Windows Cost?
The typical cost to replace one window is about $600 but can range from $200 to $1,200. But prices 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 offer door installations and replacements, which will add extra costs to your project.
Whether or not you pick energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $443 a year on your energy bills in Parker.
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 provide good insulation. Composite frames made with wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
The first step when planning a window installation is to clarify whether you should get a full-frame or pocket installation.
Full-frame installations involve replacing the whole 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 time-consuming and will increase overall costs. Pocket installations (or retrofits) entail replacing a 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.
Your window installer should be able to help you choose which type of installation you should get.

How We Choose the Best Window Installers in Parker
EcoWatch reviews are different from other reviews since we examine these companies through a sustainability lens. We’ve assessed the best window replacement companies in Parker mostly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve Parker so you can find a quality window installation company near you.
Work Quality
When installing new windows, the quality and range of services often plays just as important of a role in insulation and performance as the type of window you choose. 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
Customer feedback is another super important review factor. If most customers don’t have good feedback about their service from a certain installer, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installers are not going to provide the most quality service. On the other hand, 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
As discussed, windows are a significant investment, so you’ll want to make sure that investment is well protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Parker’s climate, homeowners will want to mitigate rot, low efficiency and water damage. We factored in local experience to reflect the ability of Parker window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Parker, CO Window Replacement FAQs
What is the average cost to install new windows?
The national average cost to install one window is around $600 but can range from $200 to $1,200, depending on a variety of 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 best for energy efficiency?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you’ll have the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — they’re certified energy-efficient by the U.S. Department of Energy.
Can you replace your own windows?
If you’re handy and have experience with similar home improvement projects, you may be able to install your own windows. However, if you don’t have the time or skills, we don’t recommend trying it.
Should I replace all my windows at once?
If you want to get more efficient windows and save money on energy costs, replacing all of your windows together is the only way to see a noticeable difference. However, if you have only a few windows that are damaged or leaky, you can replace just those.
