Why you can trust EcoWatch

How Installing Energy-Efficient Windows in Hanahan Saves You Money
By upgrading to energy-efficient windows, you can take advantage of several benefits, including:
- Reduce your carbon footprint: Decreasing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 357 pounds.
- Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your home if you decide to sell.
- 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.
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Switching to energy-efficient models can help decrease how much energy is used in your home, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Hanahan
When looking into window installation, each company offers varying services and costs. Let’s look at some average costs and services.
How Much Do New Windows Cost?
According to our research, the national average cost to install a single window is around $600. However, window replacement costs can range from $200 to $1,200 for each window. This is because of the fact that the cost of window installations are based on a variety of factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.
Keep in mind that energy-efficient windows may come at a higher price point, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 a year when replacing double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
Costs will also vary depending on the material you want for your window frames. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
The first question to ask yourself when planning on installing new windows is: Should you get a full-frame installation or a pocket installation?
Full-frame installations require replacing the full window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has a great amount of damage. Full-frame installations are more involved and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are on the simpler end and won’t carry as large a bill, but you can’t do this type of installment if you have any pre-existing rot or water damage.
Your window installation company can recommend the best type for your project. In Hanahan, the choice will mostly depend on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Hanahan
In our search to make your home improvements easier and more eco-friendly in Hanahan, EcoWatch evaluated dozens of companies before landing on these. We’ve decided to evaluate the best window replacement companies in Hanahan 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 reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Hanahan, we gave more points to companies that provide services to the city. There are other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Hanahan.
Work Quality
We’re certain that you’re looking for a company to do a great job installing windows. We’ve vetted each installer on this list to make sure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of installation, cost, warranty, professionalism, quality of parts and more.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers want 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 substantial investment, so you’ll want to be certain that investment is well protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a good track record in the industry. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Hanahan, SC Window Replacement FAQs
How much should a window install cost?
The national average cost of installing a single window is around $600 but can range from $200 to $1,200, depending on several factors. The price is often influenced by the size of the window, the type and material of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the most common types of replacement windows?
The most common types of windows for homes are double-hung and single-hung windows, casement windows, transom windows, bay windows, awning windows, picture windows and slider windows.
Can you replace your own windows?
While you can install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Using a window installation company can help ensure that the job is done properly and that you can avoid spending the time and effort of doing it yourself.
Should I replace all my windows at once?
If you’re upgrading your windows to get more efficient windows, replacing all of the windows at the same time is the only way to see a noticeable difference. However, if you have only a few windows that are broken or leaky, you can replace just those.
How long does it typically take to install windows?
Because a window takes about 30 minutes to install, around 16 windows can be installed during a typical 8-hour work day.
