How Installing Energy-Efficient Windows in Portland Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more ways upgrading your windows could help you:

  • Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. 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 switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out damaging UV rays.
  • Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can cut your carbon footprint by about 12%, according to Energy Star.
  • Save on energy bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of residential energy use. Upgrading to energy-efficient windows can help decrease that number, which helps you save more on your bills.

Estimated Cost of Window Replacement in Portland

When looking into window installation, each company offers different services and prices. Let's take a look at some average costs and services.

How Much Do New Windows Cost?

According to our research, the national average cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. How much it will cost depends on several factors, such as number of windows, the location of your home, type, size, material and more.

It's also worth noting that energy-efficient windows will usually cost more initially, but Energy Star estimates that switching out the windows on your Portland home translates to 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. How much you'll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Costs will also vary depending on the material you choose for your window frames. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

In general, there are two kinds of window replacement services companies provide: full-frame and pocket installations.

A full-frame installation is a total window replacement. It involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve other materials, including insulation and drip edges, which raise the total cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you're not sure which kind of window installation service you should get, your installer should be able to 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 Portland

The EcoWatch Reviews team differs from other reviewers because we look at these companies through a sustainability lens. We've evaluated the top window replacement companies in Portland mostly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

Since this is a guide for Portland, we only included companies that cover the city. There are certainly reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Portland.

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 company included in our guide to make sure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

Customer feedback is another super important review factor. If the majority of customers don't have nice things to say about their service from a certain company, you won't see it featured on EcoWatch.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we awarded 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 make sure that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Portland, CT Window Replacement FAQs

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

The national average cost to install a window is about $600 but can range from $200 to $1,200, depending on a few different factors. The price is usually dependent on the location of your property, the size of the window and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

What are the kinds of windows?

There are various types of windows you can get for your house, including slider windows, double-hung and single-hung windows, bay windows, picture windows, casement windows, awning windows and transom windows.

When should I use a window installation company?

Unless you have home repair skills and have the time to replace your own windows, we recommend hiring a professional. The process of installing windows is quite involved and can take anywhere from four to six hours for one window. Although it's tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and much safer alternative.

How long does window installation usually take?

Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can take two days or more if you need to have a lot of windows installed.

When is it time to replace your 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. Apart from that, if your windows have any damage on them, or they have become difficult to operate, they may need to be replaced.
