How Installing Energy-Efficient Windows in Shiloh Saves You Money
When you upgrade to energy-efficient windows, you may see several perks, such as:
- Save on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you use less energy.
- Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can reduce your carbon footprint by about 12%, according to Energy Star.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- 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 home if you decide to sell.
Estimated Cost of Window Replacement in Shiloh
Windows come in all shapes and sizes, so costs and services will vary considerably. Here are the typical costs and services that you’ll find from window installation companies.
How Much Do New Windows Cost?
Typically, Shiloh homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at about $600. But costs will vary significantly based on the quality of your products, the number of windows you need, the current condition of your home and your location. Many window companies also offer door installations and other add-ons like baths, shutters, coating and more. These extra services will increase overall project costs.
Keep in mind that energy-efficient windows may come at a higher price point, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
Getting free quotes from multiple providers is the best way to find out which one is right for you.
What Services do Window Installers Offer?
In general, there are two kinds of window installation services companies provide: full-frame and pocket installations.
Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of deterioration. With this service, your professionals will replace the entire window, including the frame, sill and trim. Pocket installations are on the simpler end and won’t cost as much, as they entail merely replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.
Your window replacement company should be able to help you figure out what’s best for your needs. In Shiloh, the decision will mostly depend on the age of your home and if there’s any moisture damage. Wood can decay if not maintained properly over the years, so it’s good to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Shiloh
In our hunt to make your home improvements easier and more eco-friendly in Shiloh, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. We have assessed the top window installation companies in Shiloh 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 considers the following factors:
Service Area
Since this is a guide for Shiloh, we gave more points to companies that cover the city. There are certainly reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Shiloh.
Work Quality
We’re certain that you’re looking for professionals who do a great job installing windows. We’ve vetted each company in our guide to ensure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If most customers don’t have nice feedback about their service from a certain window installation company, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installers are not going to provide the highest quality service. On the other hand, we want to ensure 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 give you 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 proven track record in the industry. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Shiloh, IL Window Replacement FAQs
How much does window installation cost?
The average cost to install a window ranges from $450 to $650. There are a variety of factors that influence the price, such as local labor costs, styles and sizes of windows, the materials used in designing the windows, your property’s location, the number of windows and how energy-efficient the windows are.
What kind of window is the most energy-efficient?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you’ll have the most energy-efficient windows, look for models with the blue Energy Star certification — they’re certified energy-efficient by the U.S. Department of Energy.
What do window installation companies do?
Window installation companies will do the entire process — from replacing old windows with new ones to cleaning up after the windows have been put in place. Additionally, some companies offer window manufacturing, customization and repairs.
How often should you replace your windows?
Windows generally have a lifespan of about 20 to 30 years, but anytime you see damage on your windows, it’s a good idea to have them checked by an expert to see if they are in need of a repair or replacement.
Should I replace all my windows at the same time?
If your windows are greater than 20 years old, you most likely need to replace all of them. At that point, they are often less efficient, draftier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
