    How Installing Energy-Efficient Windows in Kent Saves You Money

    When you switch to energy-efficient windows, you may see some perks, including:

    • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
    • Protect your investment: If you have an older home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.
    • Save on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Upgrading to energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
    • Decrease your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Kent, that’s about 271 pounds per year on average.

    Estimated Cost of Window Replacement in Kent

    Windows come in varying shapes, styles and purposes, so costs and services will vary greatly based on your project. Below, we describe the average cost and services that you’ll find from window installation companies.

    How Much Do New Windows Cost?

    Even though the typical cost to install one window is around $600, it can range anywhere from $200 to $1,200. But costs differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations and replacements, which have a higher price tag.

    Bear in mind that energy-efficient windows may cost more upfront, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.

    Something else that influences the total cost is the material of the frame you select. Aluminum frames are generally the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

    What Services do Window Installers Offer?

    The first step when planning an installation is to decide whether you need a full-frame or pocket installation.

    Full-frame installations are necessary when you want a new style or your window has a lot of rot. With this service, your installers will replace the whole window, including the frame, sill and trim. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and will be less expensive, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

    Your window replacement company will be able to help you figure out what’s best for your needs. In Kent, the decision will mostly depend on the age of your windows and if there’s any damage. Wood can decay if it’s not maintained properly over the years, so it’s a good idea to have a professional assess your frames and window sills.

    How We Choose the Best Window Installers in Kent

    EcoWatch reviews are different from other reviews, as we look at these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and ranked them using the following methodology:

    Service Area

    Because this is a guide for Kent, we paid more attention to companies that cover the city. There are other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Kent.

    Work Quality

    When picking new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand of window you choose. We do give window installers higher marks 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 highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including professionalism, cost, quality of installation, quality of parts, warranty and more.

    Cost

    This one is a give-and-take: similar to other services, cheap window installation companies are not going to provide the most quality service. Still, 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

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

    Years of Experience

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

    Kent, WA Window Replacement FAQs

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

    The average cost to replace a window ranges between $450 and $650. There are several factors that affect how much it costs, including styles and sizes of windows, the materials used in designing the windows, your property’s location, how energy-efficient the windows are, local labor costs and the number of windows.

    What are the most common kinds of replacement windows?

    The most common kinds of windows for homes are bay windows, picture windows, slider windows, awning windows, double-hung and single-hung windows, casement windows and transom windows.

    Can I replace my own windows?

    Even though you can install your own windows, doing so requires a lot of time and handiness. Using a window installation company can help guarantee that the installation is done properly and that you can avoid spending the time and effort of doing it yourself.

    How often should you replace your windows?

    Windows typically have a lifespan of around 20 to 30 years, but anytime you see damage on your windows, it’s a good time to have an expert take a look at them to determine if they need any repairs or replacements.

    Should I replace all my windows at the same time?

    If your windows are more than 20 years old, you most likely need to replace all of them. At that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
