How Installing Energy-Efficient Windows in Kirkland Saves You Money

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

• Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
• Decrease your carbon footprint: By using less energy once you upgrade to energy-efficient windows, you’ll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Save money on power bills: After you install energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll need less energy to heat or cool your house.
• Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Kirkland

Let’s go over the cost of updating your windows and the kinds of services you may need for your home.

How Much Do New Windows Cost?

The average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. Costs will vary considerably based on the quality of your products, the current condition of your home, your location and the number of windows you need. A lot of window companies also offer door installations and other add-ons like shutters, coating, baths and more. Additional services will increase overall project costs.

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

Costs will also vary depending on the material you pick for your window frames. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made using wood fibers encased in plastic also offer 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 offer: full-frame and pocket installations.

A full-frame installation is a replacement of the full window. This service involves removing the old window, the sill, and the exterior and interior trim. It can also involve extra materials, including insulation and drip edges, which increase 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. A pocket installation entails installing a new window within the existing frame. This means instead of removing the whole unit and rebuilding it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re still trying to decide which kind of installation you should get, you can talk to your installer and get their recommendation. The choice mostly is influenced by the age of your window frames and if there’s any damage.

How We Choose the Best Window Installers in Kirkland

EcoWatch reviews differ from most reviews because we assess these companies through a sustainability lens. We’ve evaluated the top window installers in Kirkland mainly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows can reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

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

Work Quality

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

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the most customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including professionalism, quality of parts, warranty, quality of installation, cost and more.

Cost

This one is a give-and-take: as with most services, cheap window installers won’t always provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that offer a range 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 provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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