How Installing Energy-Efficient Windows in Ofallon Saves You Money

There are quite a few benefits of switching to energy-efficient windows. Some reasons you may want to consider making the switch include the following:

  • Decrease your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Ofallon, that's about 642 pounds per year on average.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
  • Save 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 about $289 annually on your energy bills in Ofallon.
  • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Ofallon

Windows come in varying purposes, shapes and styles, so costs and services will vary greatly based on your project. Below, we go over the average cost and services that you'll find from window installation companies.

How Much Do New Windows Cost?

Typically, homeowners in Ofallon can expect that most window installations will cost between $250 and $1,200, with the average cost at about $600. But costs will differ considerably based on your location, the number of windows you need, the current condition of your home and the quality of your products. Many window companies also offer door installations and other add-ons like baths, shutters, coating and more. These extra services will increase your overall project costs.

Keep in mind that energy-efficient windows may have a higher price, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.

Getting free quotes from multiple companies is the best way to find out which one is right for you.

What Services do Window Installers Offer?

Generally, there are two types of window installation services companies offer: full-frame and pocket installations.

A full-frame installation replaces the complete 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 are on the simpler end and won't carry as large a bill because they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you may have to get a full-frame installation instead.

If you're still debating which kind of installation you need, you can ask your provider and get their advice. The choice mostly is influenced by the age of your window frames and if there's any damage.

How We Choose the Best Window Installers in Ofallon

In our hunt to find the most reliable, eco-friendly window installers in Ofallon, the EcoWatch Reviews team examined dozens of companies before settling on these. Along with energy efficiency, we assessed several window installers in Ofallon and ranked them using the following methodology:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find a quality window installation company near you.

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 included in our guide to make sure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of installation, quality of parts, professionalism, warranty, cost and more.

Cost

This one is a give-and-take: similar to most services, cheap window installation companies are not going to provide the highest quality service. Still, we want to make sure we're highlighting companies that provide a range of price and financing options so they're accessible to most homeowners.

Warranty

As discussed, windows are a sizable investment, so you'll want to make sure that investment is well protected. Window installation companies with 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 installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Ofallon, IL Window Replacement FAQs

How much should a window install cost?

The average cost of replacing a single window ranges from $450 to $650. There are many factors that influence the cost, including local labor costs, the materials used in designing the windows, your property's location, the number of windows, how energy-efficient the windows are and styles and sizes of windows.

What are the most common types of replacement windows?

The most common types of windows for homes are casement windows, awning windows, bay windows, transom windows, picture windows, slider windows and double-hung and single-hung windows.

Can I install my own windows?

If you're handy and have the time and patience to do the job right, it's possible to install your own windows. But if you don't have the time or know-how, we recommend hiring a professional.

How often should you replace windows?

Windows usually have a lifespan of 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 need any repairs or replacements.

Should I replace all my windows at once?

If you're upgrading your windows to get more efficient windows, replacing all your windows at the same time is the only way to see a noticeable difference. However, if you have just one or two windows that are damaged or leaky, you can replace just those.
