How Installing Energy-Efficient Windows in Welcome Saves You Money
There are several benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch include the following:
- More efficient energy usage in your household: Because the summers can get pretty hot in Welcome, homeowners often rely on their air conditioner during that time. Energy-efficient windows lower the amount of cool air that is lost through your windows, which makes it easier to keep your house cool.
- Better temperature control in your home: Energy-efficient windows can lower the amount of heat lost through your windows when heating your home.
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can reduce your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Welcome
Let's take a look at the cost of installing new windows and the types of services you may need for your home.
How Much Do New Windows Cost?
Typically, Welcome homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at around $600. Costs will differ considerably based on the number of windows you need, the current condition of your home, the quality of your products and your location. A lot of window companies also offer replacement door installations and other add-ons like baths, shutters, coating 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 if you live in a hot climate — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Welcome homeowners $357+ per year after replacing single-pane windows.
We advise requesting free quotes from multiple window installers to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
The first step of a window replacement is to think about whether you need a full-frame or pocket installation.
Full-frame installations are usually done when you want to change the style of your windows or your window has significant rot or deterioration. With this service, your installers will replace the whole window, including the frame, sill and trim. Pocket installations are simpler and won't cost as much, as they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.
Your window installation company can recommend the best type for your project. In Welcome, the decision will mostly be based on how much damage there is currently and the condition of your existing frames.

How We Choose the Best Window Installers in Welcome
EcoWatch is different from other reviewers, as we look at these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings using the following methodology:
Service Area
Since this is a guide for Welcome, we gave more points to companies that provide services to the city. There are certainly other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Welcome.
Work Quality
When installing new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand you get. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have good feedback about their experience with 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 providers' prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a considerable investment, so you'll want to make sure that investment is protected. Window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Welcome, SC Window Replacement FAQs
How much should window installation cost?
The average cost of installing a single window can range from $450 to $650. There are a variety of factors that influence the cost, such as local labor costs, the materials used in designing the windows, your property's location, how energy-efficient the windows are, the number of windows and styles and sizes of windows.
Which type of window should I get?
A window's energy efficiency is influenced by a number of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient since they are certified by the U.S. Department of Energy.
When should I use a window installation company?
Unless you have home repair skills and have the time needed to replace your own windows, we recommend hiring the pros. The window installation process 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 safer alternative.
Should I replace all my windows at the same time?
If your windows are greater than 20 years old, it's probably time to replace all of them. At that point, they are often less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
