How Installing Energy-Efficient Windows in South River Saves You Money
Energy-efficient windows can provide benefits in more than one way. Here are some reasons you may want to make the switch:
- Save money on power bills: Once you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% because you'll need less energy to heat or cool your house.
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- 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 Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.
- Better temperature control in your home: When you live in a place like South River where the winters can be very cold, you often have to depend on your heater to keep your house warm. Energy-efficient windows can cut back on how hard your heater needs to work to heat your home.
Estimated Cost of Window Replacement in South River
Windows come in varying shapes and sizes, so costs and services will vary tremendously. Here are the average costs and services that you can find from the average window installation company.
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. Costs will differ significantly based on the current condition of your home, the number of windows you need, the quality of your products and your location. A lot of window companies also offer door installations and other add-ons like coating, shutters, baths and more. These extra services will increase your overall project costs.
With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save South River homeowners $306+ each year after replacing single-pane windows.
Another factor that affects the overall cost is the material you pick for your frame. Aluminum frames are usually the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive, 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?
Generally, there are two kinds of window installation services you can get: full-frame and pocket installations.
Full-frame installations entail replacing the total window, including the trim, frame and sill. You most likely need a full-frame installation when you want a new style or your window has considerable rot or deterioration. Full-frame installations are more involved and will raise overall costs. A pocket installation involves replacing a window within the existing frame. So, instead of removing the whole window and reinstalling it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installer can help you decide which type of installation you should get.

How We Choose the Best Window Installers in South River
EcoWatch is different from most reviewers because we're examining these companies through a sustainability lens. Along with energy efficiency, we assessed several window installers in South River and ranked them using the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve South River so you can find a quality window installation company near you.
Work Quality
We're certain that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer included on this list to make sure its contractors are well-qualified and that the company has received 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 things to say about their experience with a certain company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window companies won't always provide the most quality service. On the other hand, we want to make sure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a hefty 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
Because of South River's climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of South River window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
