How Installing Energy-Efficient Windows in St. James Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to make the switch:
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, particularly if you have an older home.
- Save money on energy bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Switching to energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
- Decrease your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 345 pounds.
- Better temperature control in your home: When you reside in a city like St. James where the summers can get very hot, you usually need to depend on your air conditioner to keep your home cool. Energy-efficient windows can reduce how much cool air is lost through your windows when cooling your home.
Estimated Cost of Window Replacement in St. James
Each window installer offers various services and has different price points based on several factors.
How Much Do New Windows Cost?
The national average cost to replace one window is about $600 but can range from $200 to $1,200. This is due to the fact that window installations are based on a variety of factors specific to your home, such as the size, material and number of windows you need to install, as well as the location of your property.
Keep in mind that energy-efficient windows may cost more upfront, but Energy Star estimates the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 per year when installing double-pane, clear glass windows. Your savings will vary based on your local climate, energy rates and individual home characteristics.
The cost of your window installation will also vary depending on the type of window material you choose for the frames. Wood windows are typically the most expensive, but it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
Generally, there are two types of window replacement services you can get: full-frame and pocket installations.
Full-frame installations involve replacing the whole 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 deterioration. Full-frame installations are more involved and will increase overall costs. A pocket installation means replacing a window without removing the complete frame, which is generally cheaper than a full-frame installation.
If you're not sure which kind of window installation service you should get, your installer can assist you. Generally, the choice depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in St. James
EcoWatch reviews differ from other reviews because we look at these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and assigned rankings using the following methodology:
Service Area
Since this is a guide for St. James, we paid more attention to companies that serve the city. There are other reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in St. James.
Work Quality
When it comes to new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand of window you get. We do give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another super important review factor. If most customers don't have positive things to say about their experience with a certain installer, you won't see it 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 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 well protected. Window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to St. James' climate, homeowners need to be wary of rot, water damage and low efficiency. We factored in local experience to reflect the ability of St. James window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
St. James, NC Window Replacement FAQs
How much should window installation cost?
The national average cost to replace one window is about $600 but can range from $200 to $1,200, depending on several factors. The price is often dependent on the type and material of the window, the size of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What type of window is the most energy-efficient?
A window's energy efficiency is affected by a number of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.
When should I use a window installation company?
You should hire a window installation professional whenever you need new windows. Installing windows is a involved process that can be difficult to do on your own, so it's best left to the professionals.
How long does window installation typically take?
Each window takes about 30 minutes to install depending on the type of window. However, the window installation can take two days or more if you need to have a lot of windows installed.
Should I replace all my windows at the same time?
If you want to get more efficient windows and save money on your energy bills, replacing all of the windows at once is the only way to gain that benefit. On the other hand, if you have only one or two windows that are damaged or drafty, you can replace just those.
