How Installing Energy-Efficient Windows in Bangor Saves You Money

By upgrading to energy-efficient windows, you and your family can enjoy several benefits, such as:

  • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Bangor, that's about 163 pounds per year on average.
  • Save on electricity bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, the switch can help you save around $463 annually on your energy bills in Bangor.
  • Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its value.
  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Bangor

Each window installation company provides various services and has varying prices depending on a few factors.

How Much Do New Windows Cost?

Generally, Bangor homeowners can anticipate their window installations to range from $250 to $1,200. The average cost is at around $600. But costs differ considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations, which will add extra costs to your project.

It's also worth keeping in mind that energy-efficient windows will usually cost more initially, but Energy Star estimates that switching out the windows on your Bangor home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you'll save by switching to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Another factor that influences the overall cost is the material you choose for your frame. Aluminum frames are generally the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

The first question to ask yourself when planning to replace your windows is: Do you want a full-frame installation or a pocket installation?

Full-frame installations entail replacing the complete window, including the frame, trim and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable rot or deterioration. Full-frame installations are more involved and will raise the overall cost. A pocket installation involves installing a new window within the existing frame. So, instead of tearing out the whole unit and reinstalling it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company can advise you on the best type for your project. In Bangor, the decision will mostly be based on the efficiency of your home and the condition of your existing frames.

How We Choose the Best Window Installers in Bangor

In our search to find the most reliable, eco-friendly window installers in Bangor, the EcoWatch team evaluated many companies before settling on these. Along with energy efficiency, we analyzed window companies all across the state and ranked them based on the following methodology:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find a quality window installation company near you.

Work Quality

When choosing 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 opt for. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another very important review factor. If most customers don't have good feedback about their service from 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 try to keep costs low when possible. When analyzing providers' prices, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

Protecting your investment in new windows is important to many homeowners. That's why window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

Bangor, ME Window Replacement FAQs

What is the typical cost to install windows in a home?

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

What kind of window is the best for energy efficiency?

A window's energy efficiency is influenced by a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.

What do window installers do?

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

How often should you replace windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Other than that, if your windows have any damage on them, or they have become difficult to operate, they may be in need of replacement.

Should I replace all my windows at once?

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