How Installing Energy-Efficient Windows in Union Saves You Money

There are quite a few perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch are the following:

  • Better temperature control in your home: When you reside in a city like Union where the winters can get chilly, you often need to depend on your heater to keep your house warm. Energy-efficient windows can lower how hard your heater needs to work to heat your home.
  • Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can reduce your carbon footprint 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 Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
  • More efficient energy use in your household: In Union where the summers can be pretty hot, energy-efficient windows lower the amount of cool air that is lost through your windows, making it easier to keep your house cool.

Estimated Cost of Window Replacement in Union

Windows come in varying purposes, shapes and styles, so costs and services will vary greatly depending on several factors. Below, we detail the typical cost and services that you'll find from window replacement companies.

How Much Do New Windows Cost?

According to our market 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 the cost of window installations depend on several factors specific to your home, such as the size, material and number of windows you need to replace, as well as the location of your property.

Whether or not you want energy-efficient windows is another factor that will affect the cost. These will almost always cost more than other windows, but on the other hand, you can save about $391 a year on your energy bills in Union.

We recommend requesting free quotes from several window installation companies to find the right windows and the company that works best for your budget.

What Services do Window Installers Offer?

The first step of an installation is to think about whether you should get a full-frame or pocket installation.

A full-frame installation replaces the complete window, including the sill, frame, trim and the window panes. As this kind of installation requires more time, it will cost more than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the old frame. Pocket installations are simpler and will be less expensive, but you can't do this type of installment if you have any pre-existing rot or water damage.

If you're still trying to decide which kind of installation you should get, you can consult with your installer and get their recommendation. The decision mostly is influenced by how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Union

In our hunt to find the most reliable, eco-friendly window installers in Union, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we reviewed each installer and assigned rankings using the following methodology:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installers that serve Union so you can find the right window installation company near you.

Work Quality

We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer featured on this list to ensure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have nice feedback about their service from a certain window installation company, you won't see it featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window installers are not going to provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.

Warranty

As discussed, windows are a considerable investment, so you'll want to be certain that investment is protected. Window installation companies that offer 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 installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Union, SC Window Replacement FAQs

How much does window installation cost?

The national average cost to install a single window is about $600 but can range between $200 and $1,200, based on a few different factors. The price is typically dependent on the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What are the different kinds of windows?

The most common types of windows for homes include: bay windows, transom windows, slider windows, picture windows, double-hung and single-hung windows, awning windows and casement windows.

When should I use a window installation company?

Unless you're handy and have all of the necessary tools to replace your own windows, we recommend hiring a professional. The window installation process is complex and can take anywhere from four to six hours for a single window. Although it's tempting to try to save some money by doing it yourself, hiring a professional is a faster, more efficient and much safer option.

How often do you need to replace windows?

Windows generally have a lifespan of about 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have them looked at by an expert to determine if they need any repairs or replacements.
