How Installing Energy-Efficient Windows in North Star Saves You Money
Energy-efficient windows can provide benefits in more than one way. Here are a few reasons you may want to consider making the switch:
- 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 because of their ability to filter out damaging UV rays.
- Better temperature control in your home: Energy-efficient windows can lower the amount of heat lost through your windows when heating your home.
- Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading 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 accounts for about 25-30% of residential energy use. Installing energy-efficient models can help reduce that amount, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in North Star
Windows come in various styles, purposes and shapes, so costs and services will vary greatly based on your project. Below, we go over the average cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
The national average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. This is because 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 where your property is located.
It's also worth bearing in mind that energy-efficient windows will usually cost more initially, but Energy Star estimates that switching out the windows on your North Star home translates to an average energy savings of $236 to $319 a 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 installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
We recommend getting free quotes from several window companies to find the one that works best for your budget.
What Services do Window Installers Offer?
In general, there are two kinds of window installation services companies provide: 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 significant deterioration. With this service, your installers will replace the full window, including the frame, trim and sill. A pocket installation entails replacing a window without replacing the frame. This means instead of tearing out the whole window and reinstalling it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
If you're unsure which window installation service you should get, your installer should be able to advise you. Typically, the choice is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in North Star
In our hunt to find the most reliable, eco-friendly window installers in North Star, the EcoWatch team examined many companies before deciding on these. Along with energy efficiency, we evaluated several window installers in North Star and ranked them based on the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve the North Star area so you can find the right window installation company near you.
Work Quality
We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each installer in our guide to make sure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have good feedback about their service from a certain installer, you won't see it featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a hefty investment, so you'll want to make sure that investment is protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to North Star's climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of North Star window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
North Star, DE Window Replacement FAQs
How much should window installation cost?
The national average cost of replacing one window is around $600 but can range from $200 to $1,200, based on several factors. The price is often dependent on the location of your property, the type and material of the window and the size of the window. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What are the different kinds of windows?
The most common kinds of windows for homes include: picture windows, transom windows, double-hung and single-hung windows, slider windows, casement windows, awning windows and bay windows.
Can you replace your own windows?
While you can install your own windows, doing so requires a lot of time and handiness. Hiring a professional can help ensure that the job is done properly and that you won't have to spend the time and effort to do it yourself.
Should I replace all my windows at the same time?
If you're upgrading your windows to get more efficient windows, replacing all of your windows together 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.
