How Installing Energy-Efficient Windows in Mukilteo Saves You Money

Upgrading to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more details about how switching out your windows could help you:

• Save on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for around 25-30% of household energy use. Installing energy-efficient windows can help lower that number, which helps you save some money on your bills.
• Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Mukilteo, that’s about 271 pounds per year on average.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
• Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Mukilteo

When researching window installation, each company provides varying services and prices. Let’s take a look at some typical costs and services.

How Much Do New Windows Cost?

The typical cost to install a single window is about $600 but can range from $200 to $1,200. How much it will cost varies depending on several factors, like number of windows, type, the location of your home, material, size and more.

It’s also worth bearing in mind that energy-efficient windows will cost more upfront, but Energy Star estimates that upgrading the windows on your Mukilteo home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

The cost of your window installation will also vary depending on the type of material you choose for the frames. Wood windows are generally the most expensive, although it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

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

Full-frame installations are usually done when you want a new style or your window has significant deterioration. With this service, your professionals will replace the entire window, including the sill, trim and frame. A pocket installation involves installing a new window without replacing the frame. So, instead of tearing out the whole window and rebuilding it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re unsure which window installation service you need, your installer should be able to help you out. Typically, the choice depends on 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 Mukilteo

EcoWatch reviews differ from most reviews, as we evaluate these companies through a sustainability lens. We have assessed the best window replacement companies in Mukilteo primarily 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 have been shown to cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve the Mukilteo area so you can find a quality window installation company near you.

Work Quality

We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each company featured on this list to make sure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

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

Cost

This one is a give-and-take: as with most services, cheap window companies won’t always provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that offer a wide range of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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