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 consider making the switch:

• Save money on energy bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of residential energy use. Switching to energy-efficient windows can help decrease that number, which helps you save $396 a year on your bills.
• 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 Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help raise the value of your property if you decide to sell.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Reduce your carbon footprint: By using less energy after upgrading to energy-efficient windows, you’ll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Portland

Each window installer offers various services and has varying costs depending on a few factors.

How Much Do New Windows Cost?

The typical cost to replace a single window is about $600 but can range from $200 to $1,200. This is because the cost of window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.

Whether or not you pick energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $396 a year on your energy bills in Portland.

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

What Services do Window Installers Offer?

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

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has significant rot or deterioration. Full-frame installations are more involved and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won’t cost as much, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

Your window installation company will be able to advise you on the best type for your project. In Portland, the decision will mostly be based on how much damage there is currently and how old your existing frames are.

How We Choose the Best Window Installers in Portland

EcoWatch reviews are different from other reviews, as we evaluate these companies through a sustainability lens. We have assessed the top window replacement companies in Portland mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Since this is a guide for Portland, we paid more attention to companies that provide services to the city. There are other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in Portland.

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 choose. 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

We analyzed patterns in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including professionalism, quality of installation, warranty, quality of parts, cost and more.

Cost

This one is a give-and-take: as with most services, cheap window companies won’t always provide the most quality service. Still, we want to make sure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. That’s why 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 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.
