How Installing Energy-Efficient Windows in Florence Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here's more information on how switching out your windows could benefit you:
- Reduce your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by about 415 pounds.
- Save on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of energy use in your home. Installing energy-efficient windows can help reduce that number, which helps you save some money on your bills.
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
- Protect your investment: If you have an older home, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
Estimated Cost of Window Replacement in Florence
Windows come in all shapes and sizes, so costs and services will differ greatly. Here are the typical costs and services that you can find from the average window installation company.
How Much Do New Windows Cost?
On average, homeowners in Florence can expect that most window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. This is due to the fact that window installations depend on a variety of factors specific to your home, such as the size, material and number of windows you need to replace, as well as where your property is located.
With windows, efficiency is one of the most important factors for many 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, buying certified energy-efficient windows can save Florence homeowners $406+ each year after replacing single-pane windows.
We recommend getting free quotes from multiple window installers to find the one that works best for your budget.
What Services do Window Installers Offer?
In general, there are two types of window installation services companies offer: full-frame and pocket installations.
Full-frame installations are usually done when you want a new style or your window has significant rot or deterioration. With this service, your professionals will replace the total window, including the frame, sill and trim. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won’t cost as much, but you can’t do this kind of installment if you have any pre-existing rot or water damage.
Your window installation company should be able to help you decide what’s best for your needs. In Florence, the decision will mostly depend on how old your home is and if there’s any damage. Wood can decay if it’s not properly maintained over the years, so it’s a good idea to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Florence
EcoWatch differs from other reviewers because we examine these companies through a sustainability lens. We have evaluated the best window installers in Florence mostly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve Florence so you can find the best window installation company near you.
Work Quality
We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company in our guide to ensure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If most customers don’t have nice things to say about their experience with a certain company, it won’t be featured on EcoWatch.
Cost
Cheaper windows certainly don’t 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
Protecting your investment in new windows is important. That’s why window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Florence’s climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Florence window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Florence, SC Window Replacement FAQs
How much should a window install cost?
The national average cost to replace one window is about $600 but can range from $200 to $1,200, based on a few different factors. The price is generally influenced by the type and material of the window, the size of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
Which type of window is the best?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. To be sure you’re getting the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — they’re certified energy-efficient by the U.S. Department of Energy.
Can you replace your own windows?
If you’re handy and know how to replace a window, you may be able to install your own windows. But if you don’t have the time or skills, we don’t recommend trying it.
What time of year should I replace my windows?
Even though you can install windows any time of year, warmer weather is generally better for installing replacement windows. Additionally, the weather should be dry, since rain can make the installation more difficult.
