How Installing Energy-Efficient Windows in Portsmouth Saves You Money

There are several benefits of switching to energy-efficient windows. A few reasons you may want to consider making the switch are the following:

  • Save on electricity bills: Installing energy-efficient windows reduces your energy bills by about 12% because you need less energy.
  • Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
  • Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.

Estimated Cost of Window Replacement in Portsmouth

Windows come in various purposes, styles and shapes, so costs and services will vary remarkably based on several factors. Below, we detail the average cost and services that you'll find from window replacement companies.

How Much Do New Windows Cost?

Typically, Portsmouth homeowners can anticipate their window installations to range from $250 to $1,200. The most common installations sit at approximately $600. This is because the cost of window installations depend on several factors specific to your home, such as the size, material and number of windows you need to install, as well as where your property is located.

It's also worth noting that energy-efficient windows will typically cost more upfront, but Energy Star predicts that switching out the windows on your Portsmouth home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you'll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Another factor that affects the total cost is the material you pick for your frame. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, 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?

The first step when planning an installation is to figure out whether you should get a full-frame or pocket installation.

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 deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

Your window installation company will be able to recommend the best type for your project. In Portsmouth, the decision will mostly be based on the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in Portsmouth

In our search to make your home improvements easier and more eco-friendly in Portsmouth, EcoWatch landed on the above companies as the top window installation companies in the city. We've evaluated the top window installation companies in Portsmouth mostly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to reduce 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 Portsmouth, we paid more attention to companies that serve the city. There are certainly reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Portsmouth.

Work Quality

When selecting new windows, the quality and range of services often plays just as important of a role in insulation and performance as the type of window you opt for. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent online reviews to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including cost, professionalism, warranty, quality of installation, quality of parts and more.

Cost

This one is a give-and-take: similar to most services, cheap window companies may not provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that have 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 been in the industry for quite some time. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Portsmouth, RI Window Replacement FAQs

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

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

Which kind of window should I get?

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

Do I really have to use a window installation company?

You should use a window installation company whenever you want new windows. Installing windows is a complex process that can be difficult and time-consuming, so it's best handled by the professionals.

When is the best time of year to replace windows?

Replacement windows can be installed during any season, but autumn might be best. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your house, so the temperature outside doesn't necessarily matter that much. What's more important than the temperature is that the weather should be dry.

Should I replace my windows all at the same time?

If you're upgrading your windows to save on your energy bills, replacing all of the windows at the same time is the only way to see a noticeable difference. On the other hand, if you have only one or two windows that are damaged or leaky, you can replace just those.
