Why you can trust EcoWatch
Although clean energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your house's energy efficiency can also have a large impact on home energy conservation. If you have traditional, outdated windows, your AC or heating system could be working extra hard to heat or cool your house. This means spending more on energy bills.
That's bad news for both your bank account and the environment, but one of the best window installation companies can help with that.
Efficient windows are especially important in South Brunswick, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $306 per year.

How Installing Energy-Efficient Windows in South Brunswick Saves You Money
Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more ways switching out your windows could benefit you:
- Better temperature control in your home: Living in a very cold city like South Brunswick can often mean depending on your heater to keep your home cool. Energy-efficient windows can cut back on how much heat is lost through your windows when heating your home.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
- Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, particularly if you have an older home.
- Save money on power bills: Because energy-efficient windows reduce the amount of energy needed to heat or cool your home, the switch can help you save about $306 annually on your energy bills in South Brunswick.
Estimated Cost of Window Replacement in South Brunswick
Let's take a look at the cost of window installation and the types of services you may need for your home.
How Much Do New Windows Cost?
The typical cost to replace a single window is about $600 but can range from $200 to $1,200. This is because window installations are based on several factors specific to your home, like the size, material and number of windows you need to install, as well as where your property is located.
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 provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save South Brunswick homeowners $306+ each year after replacing single-pane windows.
Something else that affects 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 offer poor insulation. On the other hand, wood frames cost the most, as 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?
The first thing to ask yourself when considering a window replacement is: Do you want a full-frame installation or a pocket installation?
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 significant rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any damage or rot, you will likely need a full-frame installation instead.
If you're hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In South Brunswick, the decision will mostly be influenced by the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in South Brunswick
In our search to make your home improvements easier and more eco-friendly in South Brunswick, EcoWatch assessed dozens of companies before settling on these. We've decided to review the top window installers in South Brunswick mainly based on energy efficiency, 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 is based on the following factors:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve South Brunswick so you can find a quality window installation company near you.
Work Quality
When it comes to 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 get. 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 online reviews to find the companies with the most consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including warranty, cost, quality of parts, professionalism, quality of installation and more.
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 gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a substantial investment, so you'll want to make sure that investment is well protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of South Brunswick's climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of South Brunswick window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
South Brunswick, NJ Window Replacement FAQs
How much should window installation cost?
The national average cost of replacing a single window is about $600 but can range between $200 and $1,200, based on several factors. The price is often dependent on the size of the window, the type and material of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
Which kind of window is the best?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you'll get the most energy-efficient windows, look for models that have the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.
Can you install your own windows?
If you're handy and know how to replace a window, you may be able to install your own windows. However, if you don't have the time or know-how, we recommend hiring a professional.
Should I replace all my windows at the same time?
If your windows are greater than 20 years old, you most likely need to replace all of them. By that point, they are usually less efficient, draftier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less time.
