How Installing Energy-Efficient Windows in Royal Oak Saves You Money

Energy-efficient windows can offer benefits in more than one way. Here are a few reasons you may want to consider making the switch:

  • Save on power bills: Because energy-efficient windows decrease the amount of energy needed to heat or cool your home, they can help you save around $309 annually on your energy bills in Royal Oak.
  • Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
  • Reduce your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 471 pounds.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in Royal Oak

Let's take a look at the cost of installing new windows and the types of services offered by installers.

How Much Do New Windows Cost?

Typically, Royal Oak homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost is at approximately $600. How much it will cost you varies depending on several factors, such as size, material, type, the location of your home, number of windows and more.

Bear in mind that energy-efficient windows may cost more, but Energy Star estimates the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.

Requesting free quotes from several companies is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

In regard to window installations, there are typically two kinds that your provider will offer: full-frame and pocket installations.

Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of deterioration. With this service, your installers will replace the full window, including the frame, trim and sill. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are simpler and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.

Your window installation company should be able to help you decide which type of installation you need.

How We Choose the Best Window Installers in Royal Oak

The EcoWatch Reviews team is different from other reviewers, as we examine these companies through a sustainability lens. We have decided to review the best window installers in Royal Oak mostly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Royal Oak, we only included companies that provide services to the city. There are certainly reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Royal Oak.

Work Quality

We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each company in our guide 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 positive feedback about their experience with a certain company, you won't see it featured on EcoWatch.

Cost

This one is a give-and-take: similar to most services, cheap window installation companies are not going to provide the most quality service. Still, we want to make sure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.

Warranty

As discussed, windows are a serious investment, so you'll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Royal Oak, MI Window Replacement FAQs

What is the average cost to install new windows?

The typical cost of replacing a single window ranges between $450 and $650. There are several factors that affect the price, which include local labor costs, your property's location, how energy-efficient the windows are, the number of windows, the materials used in designing the windows and styles and sizes of windows.

What kind of window is the most energy-efficient?

Generally, double-pane windows are more efficient than single-pane windows and windows that don't open are more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.

What services do window replacement companies provide?

Window installation professionals will do the entire process — from replacing old windows with brand new ones to cleaning up after the windows have been put in place. In addition, many companies offer window manufacturing, customization and repairs.

What time of year is a good time to replace my windows?

Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into the house, so the temperature outside isn't necessarily a big factor. What's more important than the temperature is that the weather should be dry.

Should I replace my windows all at the same time?

If your windows are greater than 20 years old, it's probably time to replace all of them. By that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
