A review of the top window replacement companies in St. Clair may not seem like the most riveting article on EcoWatch, but trust us, windows have a more direct impact on your life than you might think.

How Installing Energy-Efficient Windows in St. Clair Saves You Money

There are several benefits of switching to energy-efficient windows. A few reasons you may want to consider making the switch are the following:

  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help raise the value of your house if you decide to sell.
  • Save money on power bills: Since energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save about $316 annually on your energy bills in St. Clair.
  • Better temperature control in your home: When you reside in a place like St. Clair where the winters can get very cold, you often have to depend on your heater to keep your home warm. Energy-efficient windows can lower how hard your heater needs to work to heat your home.
  • 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.

Estimated Cost of Window Replacement in St. Clair

Windows come in different shapes and sizes, so costs and services will differ considerably. Here are the average costs and the primary services that you can find from the average window installation company.

How Much Do New Windows Cost?

The average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. These amounts are based on the specifics of your installation, including type, the location of your home, number of windows, material, size and more.

It's important to remember that windows with higher efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save St. Clair homeowners $316+ a year when replacing single-pane windows.

We recommend getting free quotes from several window installation companies to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

The first thing to ask yourself when planning on installing new windows is: Do you want a full-frame installation or a pocket installation?

Full-frame installations are usually recommended when you want a new style or your window has a lot of rot or deterioration. With this service, your professionals will replace the entire window, including the trim, frame and sill. A pocket installation entails replacing a window without replacing the frame. This means instead of taking out the whole window and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company will be able to help you figure out what's best for your needs. In St. Clair, the decision will mostly depend on how old your windows are and if there's any moisture damage. Wood can decay if it's not maintained properly over the years, so it's good to have a professional check your frames and window sills.

How We Choose the Best Window Installers in St. Clair

EcoWatch reviews differ from most reviews since we examine these companies through a sustainability lens. Along with energy efficiency, we reviewed window companies all across the state and ranked them based on the following methodology:

Service Area

Because this is a guide for St. Clair, we paid more attention to companies that serve the city. There are other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in St. Clair.

Work Quality

When picking new windows, the quality and variety 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

We analyzed trends in recent customer feedback to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including quality of parts, quality of installation, warranty, cost, professionalism and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed, windows are a hefty investment, so you'll want to be certain that investment is well protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have been in the industry for quite some time. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

St. Clair, IL Window Replacement FAQs

How much should window installation cost?

The national average cost of replacing one window is around $600 but can range from $200 to $1,200, depending on a variety of factors. The price is usually dependent on the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What are the kinds of windows?

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

Can you replace your 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. However, if you don't have the time or experience, we don't recommend doing it on your own.

How often should you replace your windows?

Windows usually have a lifespan of 20 to 30 years, but anytime you see damage on your windows, it's a good time to have them looked at by an expert to see if they are in need of a repair or replacement.
