How Installing Energy-Efficient Windows in Glen Rock Saves You Money
There are several perks of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch include the following:
- Better temperature control in your home: When you reside in a place like Glen Rock where the winters can get very cold, you often have to depend on your heater to keep your house warm. Energy-efficient windows can cut back on the amount of heat lost through your windows when heating your home.
- Save money on power bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: If you have a relatively old home, your windows are most likely outdated. Updating your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Glen Rock
Windows come in different shapes, styles and purposes, so costs and services will differ greatly depending on your project. Below, we go over the typical cost and services that you can get from window installers.
How Much Do New Windows Cost?
According to our market research, the national average cost to install a single window is about $600. However, window replacement costs can range from $200 to $1,200 a window. How much it will cost varies based on several factors, such as number of windows, type, the location of your home, size, material and more.
Bear 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 install single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.
Something else that affects the total cost is the material you select for your frame. Aluminum frames are usually the least expensive and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames cost the most because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
There are generally two types of window replacement services: full-frame and pocket installations.
Full-frame installations involve replacing the full window, including the frame, sill and trim. You most likely need a full-frame installation when you want a new style or your window has significant damage or rot. Because full-frame installations are more involved, they will raise the overall cost. Pocket installations are simpler and won't carry as large a bill because they entail simply replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.
Your window installation company will be able to advise you on the best type for your project. In Glen Rock, the choice will mostly be influenced by how much damage there is currently and the age and condition of your existing frames.

How We Choose the Best Window Installers in Glen Rock
EcoWatch is different from most reviewers, as we're examining these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and ranked them based on the following methodology:
Service Area
Because this is a guide for Glen Rock, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Glen Rock.
Work Quality
When selecting new windows, the quality and variety of services often plays just as important of a role in overall efficiency and performance as the type of window you choose. We do rate window installers higher 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 the majority of customers don't have positive feedback about their service from a certain company, 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 providers' prices, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a sizable investment, so you'll want to be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Glen Rock, NJ Window Replacement FAQs
What is the typical cost to install new windows in a home?
The typical cost of installing a window can range between $450 and $650. There are several factors that affect how much it costs, such as the materials used in designing the windows, your property's location, local labor costs, how energy-efficient the windows are, the number of windows and styles and sizes of windows.
What type of window is the best for energy efficiency?
A window's energy efficiency depends on a variety of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.
When should I use a window installation company?
Unless you're handy and have the time to replace your own windows, we recommend hiring a professional. The process of installing windows is complex and can take anywhere from four to six hours for a single window. Although it's tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer alternative.
Should I replace my windows all at once?
If your windows are more than 20 years old, it's most likely time to replace all of them. By that point, they are often less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
