How Installing Energy-Efficient Windows in Dunean Saves You Money
There are several perks of switching to energy-efficient windows. A few reasons you may want to consider making the change include the following:
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.
- Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help raise the value of your property if you decide to sell.
- Save on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of household energy use. Installing energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
- Better temperature control in your home: Living in a very hot place like Dunean can often mean needing your air conditioner to keep your home cool. Energy-efficient windows can lower the amount of cool air lost through your windows when cooling your home.
Estimated Cost of Window Replacement in Dunean
Windows come in varying purposes, styles and shapes, so costs and services will vary greatly based on your project. Below, we describe the average cost and services that you can get from window installers.
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. But costs will differ significantly depending on your location, the current condition of your home, the quality of your products and the number of windows you need. A lot of window companies also offer replacement door installations and other add-ons like shutters, coating, baths and more. Additional services will increase overall project costs.
With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — especially if you live in a hot climate — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Dunean homeowners $357+ a year after replacing single-pane windows.
The cost of your window installation will also vary based on the kind of material you choose for the frames. Wood windows are usually the most expensive, although it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
When it comes to window installations, in general there are two types that your installer will offer: full-frame and pocket installations.
Full-frame installations involve replacing the full 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 involve more time and labor and will increase overall costs. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations more simple and affordable. However, if the frame has any rot or deterioration, you will most likely need a full-frame installation instead.
Your window installation company should be able to help you figure out what's best for your needs. In Dunean, the decision will mostly be based on how old your windows are and if there's any moisture damage. Wood can decay if not maintained properly over the years, so it's good to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Dunean
EcoWatch reviews are different from most reviews because we assess these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and assigned rankings using the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve Dunean so you can find the right window installation company near you.
Work Quality
When installing new windows, the quality and variety of services often plays 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
Customer feedback is another very important review factor. If most customers don't have positive feedback about their service from a certain installer, it won't be featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. For that reason, window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Dunean's climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Dunean window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Dunean, SC Window Replacement FAQs
How much does 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 a variety of factors. The price is typically influenced by the location of your property, the type and material of the window and the size of the window. Also, remember 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?
A window's energy efficiency depends on a variety of factors, including 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.
What services do window replacement companies do?
Window installation professionals will do the entire process — from replacing old windows with brand new ones to cleaning up afterward. In addition, some companies offer window manufacturing, customization and repairs.
Should I replace all my windows at once?
If your windows are greater than 20 years old, it's most likely time to replace all of them. At that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
