How Installing Energy-Efficient Windows in SeaTac Saves You Money
Energy-efficient windows can provide benefits in several ways. Here are a few reasons you may want to make the switch:
- Save money on electricity bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you need less energy.
- Protect your valuables from fading: When you upgrade to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
- Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In SeaTac, that’s about 271 pounds per year on average.
Estimated Cost of Window Replacement in SeaTac
Each window installation company provides varying services and has varying prices depending on several factors.
How Much Do New Windows Cost?
Generally, SeaTac homeowners can anticipate their replacement window installations to range from $250 to $1,200. The most common installations sit at about $600. These estimates vary depending on specific characteristics of your installation, including size, material, the location of your home, number of windows, type and more.
With windows, efficiency is one of the most important factors for many homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — especially during the winter — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save SeaTac homeowners $366+ per year after replacing single-pane windows.
Another factor that affects the overall cost is the material of the frame you pick. Aluminum frames are typically the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
There are typically two types of window installation services: full-frame and pocket installations.
Full-frame installations are usually done when you want to change the style of your windows or your window has a lot of rot. With this service, your professionals will replace the entire window, including the trim, frame and sill. A pocket installation involves replacing a window without replacing the frame. This means instead of tearing out the whole unit and reinstalling it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company can recommend the best type for your project. In SeaTac, the decision will mostly be influenced by the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in SeaTac
EcoWatch reviews differ from other reviews because we look at these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in SeaTac and assigned rankings based on the following methodology:
Service Area
Because this is a guide for SeaTac, we only included companies that serve the city. There are other reputable providers that didn’t make the list because of the low odds that they would serve the average homeowner in SeaTac.
Work Quality
We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer included in our guide to ensure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including quality of parts, quality of installation, cost, professionalism, warranty and more.
Cost
This one is a give-and-take: as with other services, cheap window companies are not going to provide the highest quality service. Still, we want to ensure we’re highlighting companies that provide a 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 give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of SeaTac’s climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of SeaTac window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
SeaTac, WA Window Replacement FAQs
What is the average cost to install new windows?
The typical cost to install a window ranges between $450 and $650. There are many factors that affect the price, such as the materials used in designing the windows, how energy-efficient the windows are, local labor costs, your property’s location, the number of windows and styles and sizes of windows.
What kind of window is the best for energy efficiency?
A window’s energy efficiency is affected by several factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.
What services do window replacement companies provide?
Window installation companies will do the entire process — from replacing old windows with new ones to cleaning up after the installation. In addition, some companies offer window manufacturing, customization and repairs.
When is the best time of year to replace windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into the house, so the temperature outside isn’t necessarily a big factor. What’s more important than the temperature is that the weather should be dry.
