Why you can trust EcoWatch
Although environmentally friendly energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your house’s energy efficiency can also have a large impact on home energy conservation. The Department of Energy estimates that heat gained or lost through outdated or drafty windows could make up close to 30% of residential energy climate usage. In North Castle, where the energy bills are an average of $40 per month, that’s almost $$142 per year wasted.
That’s bad for both your bank account and the environment, but one of the best window installation companies can help you with that.
As windows are so important for your home, choosing the right company for you is a big decision to make. That’s why the EcoWatch team has created this list of the best window installation companies, so you can make an informed decision more easily.

How Installing Energy-Efficient Windows in North Castle Saves You Money
There are quite a few perks of switching to energy-efficient windows. A few reasons you may want to consider making the switch are the following:
- Reduce your carbon footprint: By using less energy once switching to Energy Star certified windows, you’ll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Save on electricity bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
- 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.
Estimated Cost of Window Replacement in North Castle
Let’s take a look at the cost of installing new windows and the kinds of services you may need for your home.
How Much Do New Windows Cost?
Typically, North Castle homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at around $600. But costs vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door replacements, which carry a higher price tag.
With windows, efficiency is the most important factor for many homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save North Castle homeowners $331+ each year after replacing single-pane windows.
We recommend getting free quotes from several window installers to find the one that works best for your budget.
What Services do Window Installers Offer?
The first thing to ask yourself when getting new windows is: Should you get a full-frame installation or a pocket installation?
Full-frame installations are usually done when you want to change the style of your windows or your window has significant rot or deterioration. With this service, your installers will replace the complete window, including the sill, frame and trim. A pocket installation entails replacing a window without removing the entire frame, which is generally less expensive than a full-frame installation.
Your window installer should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in North Castle
The EcoWatch Reviews team differs from other reviewers because we’re examining these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and ranked them based on the following methodology:
Service Area
Since this is a guide for North Castle, we gave more points to companies that provide services to the city. There are certainly other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in North Castle.
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 you opt for. 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 trends in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including professionalism, quality of installation, quality of parts, cost, warranty and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers’ prices, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed previously, windows are a serious investment, so you’ll want to be certain that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to North Castle’s climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of North Castle window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
