How Installing Energy-Efficient Windows in Des Moines Saves You Money

Energy-efficient windows can provide benefits in more than one way. Here are some reasons you may want to take the plunge and make the switch:

• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
• Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by 271 pounds per year on average.
• Save on power bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of residential energy use. Installing energy-efficient windows can help decrease that number, which helps you save more on your bills.
• 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.

Estimated Cost of Window Replacement in Des Moines

Each window installer provides various services and has different prices based on several factors.

How Much Do New Windows Cost?

Though the national average cost of installing one window is about $600, it can range from $200 to $1,200. But costs will vary considerably depending 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 coating, baths, shutters and more. These extra services will increase overall project costs.

With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — especially during the winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Des Moines homeowners $366+ per year after replacing single-pane windows.

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

What Services do Window Installers Offer?

There are generally two kinds of window replacement services: full-frame and pocket installations.

A full-frame installation is a replacement of the full window. This service involves removing the old window, the sill, and the exterior and interior trim. It also involves other materials, including insulation and drip edges, which raise the overall cost of the project. It’s also worth noting that it’s not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. Pocket installations are on the simpler end and won’t cost as much because they entail simply 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.

If you’re unsure which window installation service you should get, your installer can help you out. Generally, the choice is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Des Moines

EcoWatch reviews differ from most reviews, as we look at these companies through a sustainability lens. We have evaluated the best window installation companies in Des Moines mainly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for Des Moines, we only included companies that cover the city. There are certainly other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Des Moines.

Work Quality

When it comes to new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

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

Cost

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

Warranty

As discussed previously, windows are a considerable investment, so you’ll want to be certain 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

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