How Installing Energy-Efficient Windows in Dearborn Saves You Money

When you upgrade to energy-efficient windows, you may see a few perks, including:

  • Protect your investment: When you have an older home, your windows could also be outdated or drafty. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
  • Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
  • Save on energy bills: Because energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save about $312 annually on your energy bills in Dearborn.
  • 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.

Estimated Cost of Window Replacement in Dearborn

Windows come in different shapes, purposes and styles, so costs and services will vary tremendously depending on your project. Below, we detail the average cost and services that you'll find from window installation companies.

How Much Do New Windows Cost?

Though the typical of installing one window is around $600, it can range from $200 to $1,200. But costs vary remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations and replacements, which will make your project cost more.

With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Dearborn homeowners $312+ each year after replacing single-pane windows.

Getting free quotes from several providers is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

Generally, there are two kinds of window replacement services you can get: full-frame and pocket installations.

Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of rot. With this service, your installers will replace the full window, including the frame, sill and trim. A pocket installation means replacing a window without removing the entire frame, which tends to be cheaper than a full-frame installation.

If you're hiring a reputable window installation company, your company can recommend the best type for your project. In Dearborn, the decision will mostly be based on how much damage there is currently and the age of your existing frames.

How We Choose the Best Window Installers in Dearborn

EcoWatch reviews differ from most reviews because we examine these companies through a sustainability lens. We've decided to evaluate the best window installers in Dearborn mostly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to reduce 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 installation companies that serve Dearborn so you can find the right window installation company near you.

Work Quality

When it comes to new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the type of window you get. 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

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

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers' prices, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

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

Years of Experience

Last but not least, we like to see companies that have been in the industry for quite some time. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Dearborn, MI Window Replacement FAQs

What is the typical cost to install new windows?

The average cost of replacing a single window ranges between $450 and $650. There are a variety of factors that influence the cost, 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 type of window is the most energy-efficient?

Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you're getting the most energy-efficient windows, look for models that have the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.

What do window installation companies do?

Window installation companies cover the entire process — from replacing old windows with brand new ones to cleaning up after the windows have been put in place. Additionally, some companies offer window manufacturing, customization and repairs.

How long does it typically take to install windows?

Since a window takes about 30 minutes to install, about 16 windows can be installed in a typical 8-hour work day.

Should I replace all my windows at once?

If your windows are greater than 20 years old, you probably need to replace all of them. By that point, they are usually less efficient, draftier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less time.
