Why you can trust EcoWatch
A guide on the best window installation companies in Seneca may not seem like the most riveting article on the EcoWatch site, but trust us, windows have a more direct impact on your life than you might realize. The Department of Energy estimates that heat gained or lost through traditional or outdated windows could account for close to 30% of heating and cooling costs. In Seneca, where the energy bills are an average of $59 per month, that's almost $$213 per year wasted.
That's bad for your bank account and the environment, but one of the top window installation companies can help you with that.
Unlike other sites, EcoWatch ranks window companies based on energy efficiency while also taking into consideration cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Seneca Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here are more details about how upgrading your windows could help you:
- Save on energy bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you use less energy.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your property if you decide to sell.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Decrease your carbon footprint: By using less energy after switching to energy-efficient windows, you'll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Seneca
Windows come in various shapes and sizes, so costs and services will vary considerably. Here are the typical costs and services that you can find from the average window installation company.
How Much Do New Windows Cost?
According to our research, the national average cost of replacing a single window is around $600. However, window replacement costs can range from $200 to $1,200 per window. But costs vary remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations, which have a higher price tag.
With windows, efficiency is the most important factor for many homeowners. Efficient 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 Seneca homeowners $355+ a year after replacing single-pane windows.
The cost of your window installation will also vary depending on the kind of material you choose for the frames. Wood windows are typically the most expensive, although it depends if they are completely 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?
The first thing to ask yourself when planning on installing new windows is: Do you want a full-frame installation or a pocket installation?
Full-frame installations are necessary when you want to change the style of your windows or your window has a lot of rot. With this service, your professionals will replace the complete window, including the trim, frame and sill. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any damage or rot, you will most likely need a full-frame installation instead.
If you're still trying to decide which type of installation you need, you can consult with your provider and get their recommendation. The choice mostly depends on how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Seneca
EcoWatch differs from most reviewers since we're examining these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and assigned rankings using the following methodology:
Service Area
Because this is a guide for Seneca, we paid more attention to companies that serve the city. There are certainly reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Seneca.
Work Quality
When selecting new windows, the quality and range of services can often play just as important of a role in insulation and performance as the brand of window you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the most customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including warranty, quality of parts, quality of installation, professionalism, cost and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed previously, windows are a serious investment, so you'll want to make sure that investment is protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Seneca, SC Window Replacement FAQs
How much does window installation cost?
The average cost to replace one window can range from $450 to $650. There are several factors that affect how much it costs, which include the number of windows, how energy-efficient the windows are, local labor costs, your property's location, styles and sizes of windows and the materials used in designing the windows.
What are the types of windows?
The most common types of windows for homes are awning windows, slider windows, picture windows, casement windows, bay windows, transom windows and double-hung and single-hung windows.
What do window installers do?
Window installation professionals will do the entire process — from replacing your old windows with new ones to cleaning up after the windows have been put in place. In addition, many companies offer window manufacturing, customization and repairs.
What time of year should I replace my windows?
Replacement windows can be installed at any time, but warmer weather is typically better. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your home, so the temperature outside isn't necessarily a big factor. What's more important than the temperature is that the weather should be dry.
