Estimated Cost of Window Replacement in Lafayette

When considering window installation, each company offers different services and prices. Let’s go over some average costs and services.

How Much Do New Windows Cost?

According to our research, the average cost to install a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. How much it will cost varies based on several factors, including material, type, size, the location of your home, number of windows and more.

It’s important to bear in mind that windows with the best efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Lafayette homeowners $579+ a year when replacing single-pane windows.

How much your window installation costs will also vary depending on the type of window material you choose for the frames. Wood windows are generally the most expensive, although it depends on whether they are solid 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?

When it comes to window installations, there are typically two types that your installer will have: full-frame and pocket installations.

Full-frame installations involve replacing the total window, including the frame, trim and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has significant rot or deterioration. These installations are more involved and will raise overall costs. 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 not sure which window installation service you should get, your installer should be able to assist you. Typically, the decision is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.
