How Installing Energy-Efficient Windows in Union Hill-Novelty Hill Saves You Money
When you switch to energy-efficient windows, you may see some benefits, such as:
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its value.
- Save money on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Replacing your windows with energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
- Decrease your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by 271 pounds per year on average.
Estimated Cost of Window Replacement in Union Hill-Novelty Hill
Each window replacement company provides various services and has varying prices based on a few factors.
How Much Do New Windows Cost?
Typically, homeowners in Union Hill-Novelty Hill can expect that most window installations will cost between $250 and $1,200, with the most common installations sitting at about $600. But costs will differ significantly based on your location, the number of windows you need, the current condition of your home and the quality of your products. Many window companies also offer door installations and other add-ons like coating, shutters, baths and more. Additional services will increase your overall project costs.
Bear in mind that energy-efficient windows may cost more upfront, but Energy Star estimates the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 a year when you replace double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.
Something else that influences the overall cost is the material of the frame you choose. Aluminum frames are generally the least pricey 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?
There are typically two kinds of window installation services: full-frame and pocket installations.
Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has a great amount of rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won’t cost as much, but you can’t do this kind of installment if you have any pre-existing rot or water damage.
Your window installer should be able to help you choose which type of installation you should get.

How We Choose the Best Window Installers in Union Hill-Novelty Hill
In our hunt to find the most reliable, eco-friendly window installers in Union Hill-Novelty Hill, the EcoWatch team evaluated many companies before landing on these. We’ve assessed the top window replacement companies in Union Hill-Novelty Hill mainly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
Since this is a guide for Union Hill-Novelty Hill, we gave more points to companies that cover the city. There are certainly reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Union Hill-Novelty Hill.
Work Quality
When selecting new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand of window you get. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have good things to say about their experience with a certain window installation company, it won’t be featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies may not provide the most quality service. On the other hand, we want to ensure we’re highlighting companies that offer a spectrum of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed, windows are a sizable investment, so you’ll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Union Hill-Novelty Hill’s climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Union Hill-Novelty Hill window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Union Hill-Novelty Hill, WA Window Replacement FAQs
How much does a window install cost?
The average cost to install one window ranges between $450 and $650. There are a variety of factors that affect how much it costs, which include how energy-efficient the windows are, your property’s location, the materials used in designing the windows, styles and sizes of windows, the number of windows and local labor costs.
What are the different types of windows?
There are several different types of windows you can get for your house, such as casement windows, bay windows, slider windows, picture windows, double-hung and single-hung windows, awning windows and transom windows.
Do you really have to use a window installation company?
Unless you have home repair skills and have the tools needed to replace your own windows, we recommend hiring a professional. The process of installing windows is quite involved and can take anywhere from four to six hours for a single window. Although it’s tempting to try to save money by doing it yourself, hiring a company is a faster, more efficient and much safer option.
When is the best time of year to replace windows?
Even though you can install windows any time of year, warmer weather is often better for installing replacement windows. In addition, the weather should be dry, since rain can make the installation more difficult.
Should I replace my windows all at the same time?
If you want to get more efficient windows and save money on energy costs, replacing all of your windows at the same time is the only way to see a noticeable difference. On the other hand, if you have just a few windows that are damaged or leaky, you can replace just those.
