Replacement Windows VS New Construction Windows

4 minute read


If the time has come to replace your windows, you may be understandably overwhelmed by the variety of available choices, and the unfamiliar terminology used in the window business confuses the issue further for many people. For instance, you may be struggling with the decision between replacement windows and new construction windows. Here’s what you need to know to make an informed choice on this subject.

What Are Replacement Windows?

The first step in understanding what replacement windows actually are is getting a firm handle on the industry terminology. Replacement windows are also referred to as retrofit windows or insert replacement windows. Replacement windows are typically installed into pre-existing homes and are designed so that it is not necessary to remove the exterior material surrounding the windows in order for them to be installed. There are two main types of replacement windows: block frame and flush fin.

  • Block frame windows are used when the original window frame is solid and intact, leaving only the sash to be replaced before the window is installed. This procedure is usually performed on existing homes that feature exterior siding made from brick or siding.
  • Flush fin windows, otherwise known as Z-bars, are used for windows featuring aluminum construction. They’re used on homes with stucco or masonry exteriors and have a flange designed to provide added stability to the window as well as conceal its existing frame.

The Advantages of Choosing a Replacement Window vs New Construction

Because having replacement windows installed does not entail the removal of exterior materials and the entire replacement of the frame, it’s a much faster option than choosing new construction windows. Installation costs are typically much lower as well, making it an ideal choice for homeowners seeking a quick weekend upgrade. Installation of replacement windows also involves minimal household disruption since the process is relatively quick and doesn’t involve removing and replacing any of the existing construction, so you and your family won’t have to worry about loss of peace and quiet in your home — it takes an average of one day for two people to install between 10-15 of these windows as opposed to five days for the installation of the same amount of new construction windows.

When to Choose Replacement Windows

Replacement windows offer homeowners an excellent choice for existing homes with intact window frames. They are also good options if you’re on a tight budget or need to get the job done as quickly as possible.

What Are New Construction Windows?

New construction windows are primarily used when you’ve built an addition to your home or in brand new construction. The installation of new construction windows involves the removal of exterior materials so that the contractor can access the studs. The window is then installed on the studs and the exterior material is replaced.

However, some homeowners opt for new construction windows over replacement windows in an existing home for a couple of different reasons.

When to Choose New Construction Windows

If the window frame or studs have experienced extensive damage, for instance, it makes little sense to have a replacement window installed. Also, if you’ve got a particular window shape or size in mind that’s a bit unusual, new construction windows are the way to go. it’s also a good option if you are replacing the exterior siding of your home.

Advanced Window just replaced three of my windows that were aging and leaking. Eli was the installer and he was excellent. He was extremely knowledgeable and demonstrated an attention to detail and professionalism The new windows matched perfectly and they work just as designed. In addition, Eli cleaned up the work area and left it pristine. The windows were also cost effective. I highly recommend them if you need replacement windows. - 2/10/2026

We are very happy with our windows. We had an unfortunate rough start but the company moved quickly to solve the problem and our experience from then on was very positive. All Communication with the company was helpful and friendly. Our satisfaction was always their goal. The installers were friendly, careful, respectful and very competent. They completed the installation much faster than we expected and they left everything in perfect condition. We would definitely recommend Advanced Windows to everyone. - 2/06/2026

Got canvased and next thing I know I was buying all new windows and sliding glass doors. We had them do a custom color to paint match some blue trim and it turned out perfectly. The sliding glass doors are also pretty slick with a cool locking feature to make sure they get shut all the way. The only hiccup was one of the windows didn’t fit upon install but they expedited getting another one made which I was really pleased with. Overall I was extremely happy with my purchase and would recommend to others. - 2/05/2026

Advanced windows replaced 4 windows in our house. The whole window replacement took about 4 hours. The installers were very efficient and professional. I would certainly recommend Advanced Windows, and would use them again. - 2/04/2026

We love our new windows! The process from start to finish was smooth. The crew arrived on time and finished installing 15 new windows in one day! I was very impressed. You can’t beat the lifetime warranty and the quality of the windows and installation is top notch. We were well overdue for new windows and the result is fantastic! - 2/03/2026
