Estimated Cost of Window Replacement in Jennings

Windows come in varying shapes and sizes, so costs and services will vary tremendously. Here are the typical costs and the primary services that you can find from the average window installation company.

How Much Do New Windows Cost?

According to our research, the typical cost of installing a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. This is because window installations are based on a variety of factors specific to your home, like the size, material and number of windows you need to install, as well as the location of your property.

It’s also worth bearing in mind that energy-efficient windows will typically cost more upfront, but Energy Star estimates that switching out the windows on your Jennings home translates to an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you’ll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Costs will also vary based on the material you pick for your window frames. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, 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 offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

There are typically two types of window installation services: full-frame and pocket installations.

Full-frame installations entail replacing the complete window, including the sill, frame and trim. Full-frame installations are necessary when you want a new style or your window has noticeable deterioration. These installations are more involved and will raise overall costs. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations less labor-intensive and costly. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you’re hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In Jennings, the choice will mostly be based on how much damage there is currently and the age of your existing frames.
