How Installing Energy-Efficient Windows in Iowa City Saves You Money

By switching to energy-efficient windows, you and your family can benefit in several ways, such as:

• 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 money on power bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you need less energy.
• Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Iowa City

Let’s go over the cost of replacing your windows and the kinds of services offered by installers.

How Much Do New Windows Cost?

On average, homeowners in Iowa City can expect that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at about $600. But costs will vary considerably based on your location, the number of windows you need, the quality of your products and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. Additional services will increase your overall project costs.

With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Iowa City homeowners $414+ a year after replacing single-pane windows.

Costs will also vary depending on the material you pick for your window frames. Aluminum frames have the lowest price. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made with 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?

The first step when planning a replacement is to clarify whether you should get a full-frame or pocket installation.

A full-frame installation is a total window replacement. This service involves removing the old window, the sill, and the exterior and interior trim. It can also involve additional materials, including insulation and drip edges, which raise the total cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are simpler and won’t carry as large a bill, as they involve simply 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.

If you’re still trying to decide which kind of installation you should get, you can talk to your installer and get their advice. The decision mostly depends on the age of your window frames and if there’s any damage.

We’ve reviewed the top window installers in Iowa City mainly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve the Iowa City area so you can find a quality window installation company near you.

Work Quality

When choosing new windows, the quality and breadth of services can often play just as important of a role in overall efficiency and performance as the type of window 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

We analyzed patterns in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including warranty, cost, quality of parts, quality of installation, professionalism and more.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies are not going to provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that provide a spectrum 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 protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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