How Installing Energy-Efficient Windows in Oak Island Saves You Money

By switching to energy-efficient windows, you can take advantage of several benefits, such as:

  • Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Oak Island, that's about 345 pounds per year on average.
  • Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.
  • Save on energy bills: Switching to energy-efficient windows lowers your energy bills by about 12% because you need less energy.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Oak Island

Let's take a look at the cost of window replacement and the types of services offered by installers.

How Much Do New Windows Cost?

Though the national average to install one window is around $600, it can range from $200 to $1,200. How much it will cost you is based on several factors, including number of windows, type, material, the location of your home, size and more.

With windows, efficiency is the most important factor for many homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — especially if you live in a hot climate — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Oak Island homeowners $265+ a year after replacing single-pane windows.

How much your window installation costs will also vary depending on the type of material you choose for the frames. Wood windows are usually the most expensive, although it depends if they are completely 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?

In regard to window installations, there are typically two types that your installer will offer: full-frame and pocket installations.

Full-frame installations are usually recommended when you want to change the style of your windows or your window has a lot of deterioration. With this service, your installers will replace the complete window, including the frame, trim and sill. Pocket installations are on the simpler end 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 or deterioration, you may have to get a full-frame installation instead.

If you're unsure which type of window installation service you should get, your installer should be able to assist you. Generally, the choice is influenced by 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 Oak Island

EcoWatch is different from most reviewers because we assess these companies through a sustainability lens. We have evaluated the top window installers in Oak Island mainly based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Because this is a guide for Oak Island, we paid more attention to companies that provide services to the city. There are certainly reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in Oak Island.

Work Quality

When installing new windows, the quality and range 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 factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the most customer satisfaction. Customer satisfaction might be the most important factor, as it indicates the quality of services across most other categories, including cost, warranty, quality of installation, quality of parts, professionalism and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers' prices, we gave higher points 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 with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Oak Island's climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Oak Island window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Oak Island, NC Window Replacement FAQs

What is the typical cost to install windows in a home?

The average cost of replacing a window can range from $450 to $650. There are a variety of factors that affect the price, including how energy-efficient the windows are, styles and sizes of windows, the materials used in designing the windows, the number of windows, your property's location and local labor costs.

What kind of window is the best for energy efficiency?

A window's energy efficiency is affected by several 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 since they are certified by the U.S. Department of Energy.

Do I really need to use a window installation company?

Unless you have home repair skills and have the tools needed to replace your own windows, we recommend hiring the pros. The process of installing windows is complicated and can take anywhere from four to six hours for one 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.

When is the best time of year to replace windows?

Though you can install windows any time of year, warmer weather is usually better for replacing windows. Additionally, it shouldn't be raining, as rain can make the installation more difficult.

How do you know it's time to replace your windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to operate, they may be in need of replacement.
