How Installing Energy-Efficient Windows in Mukilteo Saves You Money

When you upgrade to energy-efficient windows, you may see some perks, such as:

• Save on power bills: Once you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll use less energy to heat or cool your house.
• Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by 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 make your home more comfortable and also help raise the value of your house if you decide to sell.

Estimated Cost of Window Replacement in Mukilteo

Windows come in varying shapes and sizes, so costs and services will differ greatly. Here are the typical costs and services that you can find from window installation companies.

How Much Do New Windows Cost?

Although the national average cost of installing one window is around $600, it can range from $200 to $1,200. This is because window installations depend on a variety of factors specific to your home, like the size, material and number of windows you need to install, as well as where your property is located.

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 translates to 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. The amount of money you’ll save by switching 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. Pocket installations are simpler and won’t carry as large a bill, as they involve merely replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you’re unsure which window installation service you should get, your installer should be able to help you out. In general, 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 Mukilteo

EcoWatch reviews are different from other reviews because we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in Mukilteo and assigned rankings based on the following methodology:

Service Area

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

Work Quality

We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer featured in our guide to ensure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have good feedback about their service from a certain company, you won’t see it featured on EcoWatch.

Cost

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

Warranty

As discussed previously, windows are a significant investment, so you’ll want to be certain that investment is well protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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