How Installing Energy-Efficient Windows in East St Louis Saves You Money

By switching to energy-efficient windows, you and your family can take advantage of several benefits, such as:

  • Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can lower your carbon footprint by about 12%, according to Energy Star.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its real estate value, particularly if you have an older home.
  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
  • Save money on power bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you use less energy.

Estimated Cost of Window Replacement in East St Louis

Windows come in varying shapes, styles and purposes, so costs and services will differ greatly based on several factors. Below, we detail the typical cost and services that you can get from window installation companies.

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. Costs will differ significantly depending on the current condition of your home, the quality of your products, your location and the number of windows you need. Many window companies also offer door installations and other add-ons like coating, baths, shutters and more. Additional services will increase your overall project costs.

Whether or not you opt for energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $261 a year on your energy bills in East St Louis.

Another factor that affects the overall cost is the material of the frame you pick. Aluminum frames are typically the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

The first step of an installation is to decide whether you want a full-frame or pocket installation.

Full-frame installations are usually done when you want to change the style of your windows or your window has significant rot. With this service, your installers will replace the total window, including the sill, trim and frame. A pocket installation involves installing a new window without replacing the frame. This means instead of taking out the whole unit and reinstalling it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you're unsure which window installation service you need, your installer should be able to assist you. Generally, the choice is based 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 East St Louis

The EcoWatch Reviews team differs from most reviewers since we're examining these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in East St Louis and assigned rankings based on the following methodology:

Service Area

Since this is a guide for East St Louis, we only included companies that provide services to the city. There are certainly other reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in East St Louis.

Work Quality

We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company on this list to make sure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent online reviews to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including quality of parts, warranty, professionalism, cost, quality of installation and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers would like 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

As discussed previously, 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

Due to East St Louis' climate, homeowners will want to mitigate water damage, rot and low efficiency. We factored in local experience to reflect the ability of East St Louis window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

East St Louis, IL Window Replacement FAQs

How much does a window install cost?

The national average cost to replace one window is about $600 but can range from $200 to $1,200, based on a variety of factors. The price is generally dependent on the location of your property, the type and material of the window and the size of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

Which kind of window is the best?

Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open will be 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 — that means they're certified energy-efficient by the U.S. Department of Energy.

Can I replace my own windows?

Although you can install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Using a window installation company can help guarantee that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.

What time of year is a good time to replace my windows?

Replacement windows can be installed any time of the year, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your house, so the temperature outside isn't necessarily a big factor. Most importantly, the weather should be dry.

Should I replace all my windows at once?

If your windows are more than 20 years old, it's most likely time to replace all of them. By that point, they are often less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
