Estimated Cost of Window Replacement in Lake St. Louis

Windows come in different styles, shapes and purposes, so costs and services will vary tremendously based on several factors. Below, we detail the typical cost and services that you’ll find from window installers.

How Much Do New Windows Cost?

The national average cost to replace one window is about $600 but can range from $200 to $1,200. But costs will vary significantly depending on your location, the number of windows you need, the quality of your products and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. These extra services will increase overall project costs.

With windows, efficiency is one of the most important factors for many homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — especially during the summer and winter — they can give you many years of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Lake St. Louis homeowners $382+ each year after replacing single-pane windows.

What Services do Window Installers Offer?

The first question to ask yourself when planning on installing new windows is: Do you need a full-frame installation or a pocket installation?

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has significant deterioration. Full-frame installations are more comprehensive and will increase overall costs. A pocket installation involves replacing a window within the existing frame, which is usually less expensive than a full-frame installation.

If you’re unsure which kind of window installation service you need, your installer should be able to help you out. In general, the choice depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.
