Estimated Cost of Window Replacement in Franklin

Let’s take a look at the cost of window replacement and the kinds of services you may need for your home.

How Much Do New Windows Cost?

The average cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. But prices differ considerably 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.

It’s important to note that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Franklin homeowners $308+ a year when replacing single-pane windows.

The cost of your window installation will also vary based on the type of material you choose for the frames. Wood windows are usually the most expensive, although it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

The first question to ask yourself when planning to replace your windows is: Should you get a full-frame installation or a pocket installation?

Full-frame installations are usually recommended when you want to change the style of your windows or your window has significant deterioration. With this service, your professionals will replace the total window, including the sill, trim and frame. 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 type of installment if you have any pre-existing rot or water damage.

Your window installation company should be able to help you choose what’s best for your needs. In Franklin, the decision will mostly be based on the age of your windows and if there’s any moisture damage. Wood can decay if not properly maintained over the years, so it’s good to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Franklin

In our hunt to make your home improvements easier and more eco-friendly in Franklin, the EcoWatch team assessed dozens of companies before deciding on these. Along with energy efficiency, we assessed each installer and assigned rankings using the following methodology:

Service Area

Since this is a guide for Franklin, we only included companies that cover the city. There are certainly reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Franklin.

Work Quality

We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company featured in our guide to ensure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have positive feedback about their experience with a certain installer, it won’t be featured on EcoWatch.

Cost

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

Warranty

As discussed previously, windows are a considerable investment, so you’ll want to make sure that investment is well protected. Window installation companies that offer 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 been in the industry for a while. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
