How Installing Energy-Efficient Windows in Glen Rock Saves You Money
By switching to energy-efficient windows, you and your family can benefit in several ways, such as:
- Reduce your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by 206 pounds per year on average.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
- 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 Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
- Save money on energy bills: The Department of Energy estimates that heat gained or lost via windows accounts for about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help reduce that number, which helps you save more on your bills.
Estimated Cost of Window Replacement in Glen Rock
Let's take a look at the cost of installing new windows and the types of services you may need for your home.
How Much Do New Windows Cost?
On average, Glen Rock homeowners can expect their window replacements to range from $250 to $1,200. The average cost sits at approximately $600. But costs vary remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door installations, which will add extra costs to your project.
With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Glen Rock homeowners $285+ each year after replacing single-pane windows.
Another factor that influences the total cost is the material of the frame you select. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive, 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?
Generally, there are two types of window replacement services companies offer: full-frame and pocket installations.
Full-frame installations are usually done when you want a new style or your window has significant rot or deterioration. With this service, your installers will replace the whole window, including the trim, sill and frame. A pocket installation involves replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.
Your window installer should be able to help you figure out which type of installation you need.

How We Choose the Best Window Installers in Glen Rock
The EcoWatch Reviews team is different from most reviewers since we assess these companies through a sustainability lens. We've assessed the top window replacement companies in Glen Rock primarily based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve Glen Rock so you can find the right window installation company near you.
Work Quality
When it comes to new windows, the quality and breadth of services can often play just as important of a role in insulation 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
Customer feedback is another super important review factor. If the majority of customers don't have positive things to say about their service from a certain installer, it won't be featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. That's why window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for a while. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Glen Rock, NJ Window Replacement FAQs
How much does window installation cost?
The national average cost to install one window is about $600 but can range between $200 and $1,200, based on a few different factors. The price is typically dependent on the location of your property, the type and material of the window and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What are the kinds of windows?
The most common kinds of windows for homes are transom windows, casement windows, double-hung and single-hung windows, picture windows, slider windows, bay windows and awning windows.
Can I install my own windows?
If you're handy and know how to replace a window, you may be able to install your own windows. But if you don't have the time or know-how, we recommend getting a professional to do it for you.
How long does window installation usually take?
Since a window takes about 30 minutes to install, around 16 windows can be installed in a typical 8-hour work day.
Should I replace my windows all at once?
If you're upgrading your windows because of energy-efficiency, replacing all the windows at once is the only way to see a noticeable difference. However, if you have just one or two windows that are broken or leaky, you can replace just those.
