How Installing Energy-Efficient Windows in Portland Saves You Money

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

  • Save money on power bills: Once you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% because you'll require less energy to heat or cool your house.
  • 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 Older homes usually have windows that are outdated, leaky or potentially even damaged in some way.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 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.
  • Decrease your carbon footprint: In Portland, you can reduce your indirect greenhouse gas emissions by about 163 pounds per year after you install energy-efficient windows.

Estimated Cost of Window Replacement in Portland

Windows come in different purposes, shapes and styles, so costs and services will vary considerably depending on several factors. Below, we describe the average cost and services that you can get from window replacement companies.

How Much Do New Windows Cost?

According to our market research, the average cost to install a single window is around $600. However, window installation costs can range from $200 to $1,200 a window. These amounts vary depending on specific characteristics of your installation, such as type, the location of your home, number of windows, size, material and more.

It's also worth keeping in mind that energy-efficient windows will typically cost more upfront, but Energy Star predicts that upgrading the windows on your Portland home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

We advise requesting free quotes from multiple window installation companies to find the one that works best for your budget.

What Services do Window Installers Offer?

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

Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are most common when you want a different style for your windows or when it has significant rot or deterioration. Full-frame installations are more involved and will increase overall costs. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

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

How We Choose the Best Window Installers in Portland

EcoWatch reviews are different from most reviews since we evaluate these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and assigned rankings based on the following methodology:

Service Area

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

Work Quality

We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer included on this list to make sure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews 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, quality of installation, professionalism, quality of parts, cost and more.

Cost

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

Warranty

As discussed previously, windows are a hefty investment, so you'll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a proven track record in the industry. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Portland, ME Window Replacement FAQs

How much does a window install cost?

The average cost to install a single window ranges from $450 to $650. There are several factors that affect how much it costs, including local labor costs, the number of windows, the materials used in designing the windows, how energy-efficient the windows are, styles and sizes of windows and your property's location.

Which kind of window is the best?

A window's energy efficiency depends on a number of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.

What do window installation companies do?

Window installers travel to your house to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others install their own windows. The installer will also clean up after the installation.

How long does it usually take to install windows?

Since the average installation time of a window is 30 minutes, around 16 windows can be installed in a typical 8-hour work day.

How do you know it's time to replace your windows?

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