How Installing Energy-Efficient Windows in Sunset Hills Saves You Money
When you upgrade to energy-efficient windows, you may see a few benefits, such as:
- Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by about 763 pounds.
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
- Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Upgrading to energy-efficient models can help decrease how much you have to pay, therefore saving you about 12% more on your bills.
- Protect your investment: If your home is on the older side, your windows are most likely outdated.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 raise the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Sunset Hills
When looking into window installation, each company offers varying services and prices. Let's look at some typical costs and services.
How Much Do New Windows Cost?
According to our research, the national average cost of installing a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. How much it will cost varies depending on several factors, including size, material, type, the location of your home, number of windows and more.
It's also worth noting that energy-efficient windows will usually cost more initially, but Energy Star estimates that upgrading the windows on your Sunset Hills home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
How much your window installation costs will also vary based on the kind of material you choose for the frames. Wood windows are generally the most expensive, though it depends if 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?
There are typically two types of window installation services: full-frame and pocket installations.
Full-frame installations involve replacing the complete window, including the sill, frame and trim. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant rot or deterioration. Because full-frame installations are more involved, they will increase the total cost. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.
If you're hiring a reputable window installation company, your company will be able to recommend the best type for your project. In Sunset Hills, the choice will mostly be based on how much damage there is currently and the condition of your existing frames.

How We Choose the Best Window Installers in Sunset Hills
In our search to make your home improvements easier and more eco-friendly in Sunset Hills, the EcoWatch team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings using the following methodology:
Service Area
Since this is a guide for Sunset Hills, we paid more attention 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 Sunset Hills.
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 company on this list to make sure its contractors are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including quality of installation, cost, professionalism, quality of parts, warranty and more.
Cost
This one is a give-and-take: as with other services, cheap window installation companies may not provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that provide a wide range 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 have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for a while. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Sunset Hills, MO Window Replacement FAQs
How much should a window install cost?
The national average cost to install a single window is around $600 but can range from $200 to $1,200, depending on several factors. The price is usually dependent on the location of your property, the type and material of the window and the size of the window. Also, keep in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
Which type of window is the best?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be 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 — this means they're certified energy-efficient by the U.S. Department of Energy.
What do window installation companies do?
Window installers visit your home to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others install their own windows. The installer will also clean up after the installation.
What time of year is a good time to replace my windows?
Replacement windows can be installed any time of the year, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into the home, so the temperature outside isn't necessarily a big factor. Most importantly, the weather should be dry.
Should I replace all my windows at the same time?
If you want to get more efficient windows and save money on energy costs, replacing all the windows at once is the only way to gain that benefit. However, if you have only a few windows that are broken or drafty, you can replace just those.
