How Installing Energy-Efficient Windows in Griswold Saves You Money

Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to think about making the switch:

• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
• Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its real estate value.
• Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can cut your carbon footprint by about 12%, according to Energy Star.
• Save on energy bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Upgrading to energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Griswold

Windows come in different styles, shapes and purposes, so costs and services will differ considerably depending on your project. Below, we go over the typical cost and services that you’ll find from window replacement companies.

How Much Do New Windows Cost?

Even though the average cost to install one window is about $600, it can range from $200 to $1,200. Costs will differ significantly based on your location, the quality of your products, the number of windows you need and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like baths, coating, shutters and more. Additional services will increase overall project costs.

With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Griswold homeowners $424+ each year after replacing single-pane windows.

What Services do Window Installers Offer?

When considering window replacements, in general there are two kinds that your provider will have: full-frame and pocket installations.

Full-frame installations entail replacing the full window, including the trim, frame and sill. You most likely need a full-frame installation when you want a new style or your window has significant rot. Because these installations are more involved, they will raise the total cost. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and won’t cost as much, but you can’t do this type of installment if you have any pre-existing rot or water damage.

If you’re hiring a reputable window installation company, your company can advise you on the best type for your project. In Griswold, the decision will mostly depend on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Griswold

EcoWatch reviews differ from most reviews since we’re examining these companies through a sustainability lens. We have assessed the top window replacement companies in Griswold mostly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

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 the right window installation company near you.

Work Quality

When it comes to new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand you opt for. 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 positive feedback about their experience with a certain window installation company, you won’t see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies won’t always provide the highest quality service. Still, we want to ensure we’re highlighting companies that offer a variety 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 that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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