How Installing Energy-Efficient Windows in Johnston Saves You Money

Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to take the plunge and make the switch:

• Protect your investment: When you have an older home, your windows could also be outdated or leaky. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
• Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Johnston, that’s about 715 pounds per year on average.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
• Save money on energy bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of energy use in your home. Switching to energy-efficient windows can help reduce that number, which helps you save $429 a year on your bills.

Estimated Cost of Window Replacement in Johnston

Each window replacement company offers various services and has varying price points based on several factors.

How Much Do New Windows Cost?

Typically, homeowners in Johnston can expect that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at about $600. This is because window installations are based on several factors specific to your home, including the size, material and number of windows you need to replace, as well as the location of your property.

It’s important to remember that windows with higher efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Johnston homeowners $429+ a year when replacing single-pane windows.

Costs will also vary based on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

There are typically two types of window replacement services: full-frame and pocket installations.

Full-frame installations entail replacing the complete window, including the sill, frame and trim. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable damage. Because these installations are more involved, they will raise the overall cost. 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 deterioration, you should opt for a full-frame installation instead.

Your window installation company can help you figure out which type of installation you need.

Service Area

Work Quality

We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company featured on this list to make sure its contractors are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have nice things to say about their experience with a certain company, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window companies may not provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that provide a spectrum of price and financing options so they’re accessible to most homeowners.

Warranty

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

Years of Experience

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