How Installing Energy-Efficient Windows in Effingham Saves You Money

Energy-efficient windows can provide benefits in several ways. Here are some reasons you may want to consider making the switch:

  • Save money on electricity bills: After you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll require less energy to heat or cool your house.
  • Reduce your carbon footprint: By using less energy after switching to Energy Star certified windows, you’ll also be cutting your indirect greenhouse gas emissions 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  • Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading your windows is an important part of maintaining your property and its real estate value.
  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Effingham

Each window installation company offers varying services and has different costs depending on several factors.

How Much Do New Windows Cost?

Generally, Effingham homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at about $600. These figures vary depending on specific characteristics of your installation, like number of windows, the location of your home, size, material, type and more.

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 Effingham home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you’ll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

The cost of your window installation will also vary depending on the kind of window material you choose for the frames. Wood windows are generally the most expensive, though it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

In regard to window installations, there are generally two kinds that your provider will offer: full-frame and pocket installations.

A full-frame installation replaces the full window, including the sill, frame, trim and the window panes. As this kind of installation requires more time and labor, it will be more expensive than a pocket installation. Pocket installations are on the simpler end and won’t cost as much because they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window installation company will be able to help you understand what’s best for your needs. In Effingham, 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 examine your frames and window sills.

How We Choose the Best Window Installers in Effingham

EcoWatch differs from other reviewers, as we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Effingham and assigned rankings using the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve Effingham so you can find a quality window installation company near you.

Work Quality

When picking new windows, the quality and range of services often plays just as important of a role in insulation and performance as the type of window you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don’t have nice feedback about their experience with a certain window installation company, you won’t see it featured on EcoWatch.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs low when 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 serious investment, so you’ll want to make sure that investment is well protected. Window installation companies with 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 a proven 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.

Effingham, IL Window Replacement FAQs

What is the typical cost to install windows?

The national average cost to replace a single window is about $600 but can range from $200 to $1,200, based on a few different factors. The price is typically influenced by the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

What are the most common types of replacement windows?

There are various kinds of windows you can get for your house, including picture windows, slider windows, transom windows, double-hung and single-hung windows, bay windows, awning windows and casement windows.

Can I replace my own windows?

Although you can install your own windows, doing so requires a lot of time and handiness. Using a window installation company can help ensure that the job is done properly and that you won’t have to spend the time and effort to do it yourself.

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

Even though you can install windows any time of year, warmer weather is usually better for installing replacement windows. Additionally, it shouldn’t be raining, as rain can make the installation more difficult.

How do you know it’s time to replace your windows?

Windows generally have a lifespan of around 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 determine if they need any repairs or replacements.
