How Installing Energy-Efficient Windows in Thornton Saves You Money
By upgrading to energy-efficient windows, you can take advantage of several benefits, such as:
- Better temperature control in your home: Energy-efficient windows can cut back on how hard your heating system needs to work to heat your home.
- Save money on electricity bills: Installing energy-efficient windows reduces your energy bills by about 12% since you need less energy.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Thornton
Each window installer offers varying services and has varying prices based on a few factors.
How Much Do New Windows Cost?
The average cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. This is because the cost of window installations depend on several factors specific to your home, like the size, material and number of windows you need to install, as well as the location of your property.
Keep in mind that energy-efficient windows may cost more upfront, but Energy Star estimates the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.
We advise getting free quotes from multiple window installation companies to find the one that works best for your budget.
What Services do Window Installers Offer?
The first question to ask yourself when planning to replace your windows is: Should you get a full-frame installation or a pocket installation?
A full-frame installation is a replacement of the total window. This service involves taking out the old window, the sill, and the exterior and interior trim. It also involves additional materials, like insulation and drip edges, which raise the total cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are on the simpler end and won't carry as large a bill because they entail merely replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.
If you're unsure which kind of window installation service you should get, your installer should be able to help you out. Generally, the choice depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Thornton
In our search to make your home improvements easier and more eco-friendly in Thornton, EcoWatch examined many companies before landing on these. Along with energy efficiency, we evaluated several window installers in Thornton and ranked them using the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve Thornton so you can find a quality window installation company near you.
Work Quality
When installing new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand of window you choose. 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 very important review factor is customer feedback. If most customers don't have nice things to say about their service from a certain company, you won't see it featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Thornton, IL Window Replacement FAQs
What is the typical cost to install new windows in a home?
The typical cost of replacing a window can range from $450 to $650. There are many factors that influence the cost, such as the number of windows, local labor costs, your property's location, how energy-efficient the windows are, the materials used in designing the windows and styles and sizes of windows.
What are the different kinds of windows?
There are several different types of windows you can get for your house, including double-hung and single-hung windows, awning windows, casement windows, picture windows, transom windows, slider windows and bay windows.
What services do window installation companies do?
Window installation professionals go to your home to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is finished.
How do you know it's time to replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may be in need of replacement.
