How Installing Energy-Efficient Windows in East Alton Saves You Money
When you switch to energy-efficient windows, you may see a few benefits, such as:
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your house, you can cut your carbon footprint by about 12%, according to Energy Star.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its value.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Save on power bills: Installing energy-efficient windows reduces your energy bills by about 12% because you need less energy.
Estimated Cost of Window Replacement in East Alton
Windows come in different styles, shapes and purposes, so costs and services will differ considerably depending on several factors. Below, we go over the typical cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
Generally, East Alton homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. This is because the cost of window installations depend on several factors specific to your home, such as the size, material and number of windows you need to install, as well as where your property is located.
It's also worth bearing in mind that energy-efficient windows will usually cost more initially, but Energy Star estimates that upgrading the windows on your East Alton 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. How much you'll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Costs will also vary depending on the material you pick for your window frames. Aluminum frames have the lowest price. 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 provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
The first step when planning a replacement is to decide whether you need a full-frame or pocket installation.
A full-frame installation replaces the full window, including the windowsill, frame, trim and the window panes. As this type of installation requires more time, it will cost more than a pocket installation. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.
If you're still debating which type of installation you should get, you can ask your provider and get their recommendation. The choice mostly depends on the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in East Alton
EcoWatch reviews differ from most reviews, as we're examining these companies through a sustainability lens. We've decided to assess the top window installation companies in East Alton mostly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows can reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.
Work Quality
When picking new windows, the quality and breadth 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 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 good feedback about their service from a certain company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installers won't always provide the most quality service. Still, 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. That's why window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
East Alton, IL Window Replacement FAQs
What is the average cost to replace windows?
The national average cost of installing a window is about $600 but can range from $200 to $1,200, based on a few different factors. The price is generally dependent on the size of the window, the location of your property and the type and material 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 are the most common types of replacement windows?
There are various types of windows you can get for your house, such as double-hung and single-hung windows, awning windows, bay windows, transom windows, picture windows, casement windows and slider windows.
When do I have to use a window installation company?
You should hire a window installation company whenever you need new windows. Installing windows is a complex process that can be difficult and time-consuming, so it's best left to the professionals.
How long does window installation generally take?
Because the average installation time is 30 minutes per window, about 16 windows can be installed in a typical 8-hour work day.
Should I replace my windows all 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 gain that benefit. However, if you have just one or two windows that are broken or drafty, you can replace just those.
