Estimated Cost of Window Replacement in West Haven

Windows come in various purposes, shapes and styles, so costs and services will vary tremendously based on several factors. Below, we detail the average cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

The typical cost to replace one window is about $600 but can range from $200 to $1,200. How much it will cost varies based on several factors, including material, type, the location of your home, number of windows, size and more.

With windows, efficiency is one of the most important factors for many homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the summer and winter — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save West Haven homeowners $420+ per year after replacing single-pane windows.

We recommend getting free quotes from multiple window installation companies to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

The first step of a replacement is to clarify whether you should get a full-frame or pocket installation.

Full-frame installations are usually done when you want to change the style of your windows or your window has a lot of rot. With this service, your installers will replace the entire window, including the sill, trim and frame. A pocket installation involves replacing a window within the old frame. So, instead of removing the whole unit and reinstalling it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.

Your window installation company can advise you on the best type for your project. In West Haven, the choice will mostly depend on how much damage there is currently and how old your existing frames are.

Protecting your investment in new windows is important. That’s why window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
