How Installing Energy-Efficient Windows in St. George Saves You Money
There are several benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the change are the following:
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
- Save money on energy bills: Since energy-efficient windows decrease the amount of energy needed to heat or cool your home, the switch can help you save around $479 annually on your energy bills in St. George.
- Protect your investment: When you have an older home, your windows could also be outdated or leaky.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.
- More efficient energy usage in your home: Because the summers can get quite hot in St. George, homeowners often depend on their air conditioner a lot. Energy-efficient windows reduce how much cool air is lost through your windows, making it easier to keep your home cool.
Estimated Cost of Window Replacement in St. George
Let's take a look at the cost of installing new windows and the types of services offered by installers.
How Much Do New Windows Cost?
On average, St. George homeowners can anticipate their replacement window installations to range from $250 to $1,200. The average cost sits at approximately $600. But costs will differ considerably depending on the current condition of your home, the quality of your products, your location and the number of windows you need. A lot of window companies also offer door installations and other add-ons like shutters, coating, baths and more. Additional services will increase your overall project costs.
It's also worth bearing in mind that energy-efficient windows will almost always cost more upfront, but Energy Star predicts that switching out the windows on your St. George home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you'll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
We recommend getting free quotes from several window installers to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
There are generally two kinds of window installation services: full-frame and pocket installations.
Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has significant rot or deterioration. Full-frame installations are more time-consuming and will increase overall costs. A pocket installation entails installing a new window without replacing the frame. So, instead of tearing out the whole window and reinstalling it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're hiring a reputable window installation company, your company can recommend the best type for your project. In St. George, the decision 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 St. George
In our hunt to find the most reliable, eco-friendly window installers in St. George, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. Along with energy efficiency, we evaluated each installer and ranked them using the following methodology:
Service Area
Because this is a guide for St. George, we only included companies that provide services to the city. There are certainly other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in St. George.
Work Quality
When installing new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the type of window you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have positive things to say about their service from a certain installer, you won't see it featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers' prices, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a sizable investment, so you'll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of St. George's climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of St. George window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
St. George, KS Window Replacement FAQs
How much does a window install cost?
The average cost to install a single window can range between $450 and $650. There are a variety of factors that affect the price, such as how energy-efficient the windows are, the number of windows, styles and sizes of windows, the materials used in designing the windows, local labor costs and your property's location.
Which kind of window is the best?
A window's energy efficiency is influenced by a number of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.
Do you really need to use a window installation company?
You should hire a window installation company whenever you want to replace your windows. Installing windows is a complex process that can be difficult to do on your own, so it's best handled by the professionals.
Should I replace all my windows at once?
If you want to get more efficient windows and save money on your energy bills, replacing all of your windows together is the only way to see a noticeable difference. On the other hand, if you have just a few windows that are broken or drafty, you can replace just those.
