How Installing Energy-Efficient Windows in Mill Creek East Saves You Money
When you switch to energy-efficient windows, you may see a few perks, including:
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your carbon footprint by about 12%, according to Energy Star.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.
- Save on power bills: Once you install energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll need less energy to heat or cool your house.
Estimated Cost of Window Replacement in Mill Creek East
Windows come in various purposes, shapes and styles, so costs and services will vary remarkably depending on several factors. Below, we describe the typical cost and services that you can get from window replacement companies.
How Much Do New Windows Cost?
On average, Mill Creek East homeowners can expect their window replacements to range from $250 to $1,200. The average cost is at around $600. This is due to the fact that the cost of window installations depend on several factors specific to your home, including the size, material and number of windows you need to install, as well as the location of your property.
Keep in mind that energy-efficient windows may have a higher price, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.
Costs will also vary based on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more 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?
The first step of a window replacement is to figure out whether you want a full-frame or pocket installation.
Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of damage. Full-frame installations are more comprehensive and will increase overall costs. Pocket installations are on the simpler end and won’t carry as large a bill, as they entail simply replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.
Your window installation company should be able to help you understand what’s best for your needs. In Mill Creek East, the decision will mostly depend on how old your home is and if there’s any damage. Wood can decay if it’s not maintained properly over the years, so it’s good to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Mill Creek East
In our hunt to find the most reliable, eco-friendly window installers in Mill Creek East, the EcoWatch Reviews team examined many companies before settling on these. Along with energy efficiency, we evaluated several window installers in Mill Creek East and ranked them using the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve the Mill Creek East area so you can find the best window installation company near you.
Work Quality
When installing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand of window you get. 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 customer feedback to find the companies with the most customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including professionalism, quality of parts, warranty, cost, quality of installation and more.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
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 installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Mill Creek East’s climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Mill Creek East window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Mill Creek East, WA Window Replacement FAQs
How much should window installation cost?
The typical cost to replace a window can range from $450 to $650. There are several factors that influence the cost, which include how energy-efficient the windows are, the materials used in designing the windows, the number of windows, your property’s location, local labor costs and styles and sizes of windows.
What kind of window is the best for energy efficiency?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. If you want to be sure you’ll get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they’re certified energy-efficient by the U.S. Department of Energy.
What services do window replacement companies offer?
Window installation professionals travel to your house to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others install their own windows. The installer will also clean up after the installation.
Should I replace all my windows at the same time?
If you’re upgrading your windows because of energy-efficiency, replacing all the windows at the same time is the only way to gain that benefit. On the other hand, if you have only one or two windows that are broken or leaky, you can replace just those.
How long does window installation take?
Each window takes around 30 minutes to install depending on the type of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
