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- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged.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.
