What are the Different Types of Window Installation?

Window installation is a critical piece of the puzzle when it comes to increasing your home’s performance, reducing drafts, and boosting curb appeal. While aesthetics and energy savings are heavily marketed by window companies across the nation, it’s important not to overlook the importance of correct window installation. Besides the quality of the window itself, proper window installation is essential for full energy efficiency and accurate performance for the life of the product.

While homeowners don’t necessarily think of window installation first when considering window replacement, it should be a priority to learn as much as you can about the process, including the different types of window installation. Understanding the kind of window installation needed for your home—and why—can save you from labor disruptions, or even complete performance failure.

This overview dives into the types of window installation performed by professionals ranging from the replacement window industry, to custom home builders.

The Two Types of Home Window Installation

There are two types of home window installation: full-frame installation and pocket installation. A window contractor can help you determine the best choice for your home, which is based on varying factors such as:

  • The age of the home.
  • The condition of the home.
  • Exterior materials, such as stucco or brick. According to Fine Homebuilding, full-frame replacement is even more complicated on brick or stucco homes.
  • If there is damage to the window frame, such as significant rot or deterioration. The most common place to find window damage is the exterior sill or the brickmould.
  • Budget.
  • Time restrictions.
A Window that Needs Replaced

What is Full-Frame Window Installation?

Full-frame window installation is the total replacement of a window. When a full-frame window installation is performed, it involves removing the window, the sill, exterior trim and interior trim. After a full-frame window installation is done, it’s not uncommon for homeowners to touch up the walls with fresh paint to complete the project.

Additional materials, including insulation and drip edge, are required to perform a full-frame installation, which increases the cost of the overall project.

What Does a Full-Frame Window Look Like?

Homeowners likely can’t tell the difference between a replacement window and a full-frame window from the outside of the home. However, these windows have different characteristics as the installation is much different from one another.

With a full-frame window, otherwise known as a new construction window, you’ll find that these windows include nailing fins. It’s the biggest difference in terms of appearance with replacement windows vs. new construction windows. These nailing fins are hidden during installation, but they are necessary for the window to become airtight and waterproof by fastening the window in place and flashing it.

Example Scenarios for Choosing Full-Frame Replacement Windows

While most window replacement projects work fine with window inserts, there are a few cases that might require complete replacement of the window and the frame. These are a few example scenarios of using full-frame replacement windows:

Example #1: 100-Year-Old Home with Old, Rotting Frames and Sills that are Beyond Repair

Homeowners who live in old homes are often reluctant to replace the original windows. While this is often attributed to impacting the home’s character, the other consideration is the state of the original frames.

When a window contractor comes to the home, the condition of the current windows is analyzed. If it’s discovered that there is significant damage to the frame, such as rotting or even insect infestation, full-replacement might be recommended. It’s the best choice when a window frame is so worn that the entire thing needs removed and rebuilt.

Keep in mind that just because a home is old doesn’t mean it must have the entire frame replaced. What matters is that the original window frame is in good shape. If this is the case, a homeowner can likely move forward with pocket installation instead.

Example #2: You’re Building a New Construction Home

New construction homes use a different type of window known as a new construction window. The window along with other elements such as the frame and brickmould are all added at the same time. Since there is no existing window frame (yet), the best choice in this scenario is full frame replacement for a new construction home.

Example #3: Old Windows Were Installed by Another Company

Another scenario to consider for full-frame replacement is when the windows were installed by another company. This is to ensure that the entire window unit is properly measured, installed, and no deterioration or structural issues were overlooked during the installation process.

Example #4: Original Windows are No Longer in Style

Window replacement is an excellent option for transforming curb appeal. If you’re looking to completely change the size and shape of a window, such as swapping an oval window for a picture window, full-frame window replacement is best.

What Happens During Full-Frame Window Replacement?

Regardless of the reasoning behind choosing full-frame window replacement, homeowners can expect the following during the installation process:

  • Removal of the window and frame down to the rough opening.
  • The opening is then sealed to prevent water and air from seeping inside the home.
  • Insulation is added to further prevent energy loss.
  • When the new window is positioned in place, a water system is added at the sill. This is essential to reducing water damage to the frames and causing problems such as mold, especially if the frames are wood. The water management system depends on flashing in this instance rather than caulking.

Pros and Cons of Full-Frame Window Replacement

If you’re thinking that full-frame window replacement is the right choice for your home, consider the following pros and cons for this type of window installation:

Full-Frame Window Replacement Pros

  • The best option for window frames that are severely deteriorating.
  • Perfect if you want to change the shape and style of a window opening.
  • Full-frame replacement allows installers to address lack of insulation around the window frame.
  • Full-frame provides slightly more glass which can extend views of the outdoors. This is because the glass is closer to the original window frame.

Full-Frame Window Replacement Cons

  • Full-frame window replacement is labor intensive. When some homes can get new insert replacement window as quickly as one day, full-frame windows will take much longer to install.
  • With older homes, variations between sash openings can cause installation that’s too tight or too loose. This can lead to a myriad of problems including energy loss.
  • With more material and labor required, full-frame window replacement is considerably more expensive than insert replacement windows. Homeowners can pay as much as 50% to 100% more for full-frame than insert replacement windows.

What is Pocket Installation?

Pocket installation is the method of replacing windows within the existing frame. Instead of tearing out the entire unit and rebuilding it, the replacement window---otherwise known as a retrofit or insert window---is slid into place by a professional window contractor.

Replacement windows come in a variety of materials, shapes, and sizes, with vinyl replacement windows serving as 36% of window sales in America.

What Does an Insert Replacement Window Look Like?

Insert replacement windows come in two styles: flush-fin and block-fit.

Flush-fin is a generic term that has many name variations in the industry, including stucco fin, retrofit flange, retrofit fin, and retrofit flange. Other major brand names have their own name variations, such as Z-Bar.

With flush-fin, the new window is installed on top of the existing perimeter frame. The frame’s flush fins are used to create a seamless application with the main frame of the new window. This is the most ideal window installation method if there is no water or structural damage to the window opening.

Block-fit windows are normally used for homes that have existing wood windows---which are typically double hung or casement style. The block-fit window does not include any type of fin. Instead, this window is inserted into the pocket of an existing frame. The original wood frame is left in place and it must be in good condition for this style of window installation to work.

Pocket Window Replacement

Example #1: Upgrading a Home with Stucco or Brick Exterior

Depending on where you live in the country, the exterior material of your home can play a role in the right type of window installation. According to Angie’s List, there is a layer of mesh behind stucco exterior that is difficult to cut. This can make full-replacement difficult, especially without damaging the exterior. It’s the same case with brick.

Retrofit window replacement is achievable with any type of exterior. While full-frame window replacement poses a problem with brick or stucco, it’s a snap with insert windows. By using the existing frame that’s already in the home, a window installer puts the new window in place while creating an airtight seal for maximized energy savings.

Example #2: Homeowners Want Significant Return on Investment

One of the most compelling aspects of vinyl window replacement is that it offers one of the top ROIs in the home remodeling industry. According to 2018 Cost vs. Value by Remodeling, homeowners can expect a return on investment of roughly 75%. This is the ideal upgrade for putting a home on the market to sell or increasing overall properly value.

Example #3: Fast and Affordable Window Upgrade

While the cost of replacement windows is widely variable, the common denominator is that they’re less expensive than new construction.

The lower price tag is due to fewer materials required to install. This results in less work for the window contractor, and a faster turnaround time for project completion.

Even though insert replacement windows offer a fast way to upgrade the home, it’s important to emphasize quality performance during the installation process. Experienced window contractors know the best techniques in the industry for correct window installation. Therefore, it’s important to hire a reputable and experienced window contractor to install new replacement windows.

Example #4: Maintenance Free Window Upgrade

Specifically, vinyl window replacement is one of the easiest home upgrades to maintain. There is nearly no maintenance involved for this type of window installation other than occasional cleaning between seasons.

However, if a homeowner chooses wood windows, extra maintenance is necessary to keep the window looking beautiful. This includes sanding, staining, and painting the window as well as treating the wood to resist moisture.

What Happens During Pocket Installation?

  1. Window installers arrive at the home and will cover any items that need protected during the process, such as outside landscaping. It’s helpful to tell the project manager if pets are on the premise so the team can use extra care.
  2. Since the new windows are going inside of the old opening, there is generally no need to remove the trim.
  3. Once the property is prepared, the old windows are carefully removed. Professional window installers try to not break the glass of the old window to prevent any accidents or injuries.
  4. If deteriorated material is discovered, this is addressed before the new window is installed in the opening.
  5. As the window is being positioned, the installers check that the area is level and plumb. This is to ensure that the window fits correctly in the space and does not result in any gaps or energy loss.
  6. The window is sealed, caulked, and insulated on the interior and exterior. This further promotes window performance and can help homeowners save potentially hundreds of dollars per year on energy bills.
  7. When window installation is completed, the team will clean up the area and remove any remaining debris. This includes debris found inside the home, on the driveway, and any excess materials are bagged or thrown in a dumpster. Your old windows are disposed of or sent to recycling.
  8. The project manager will do a final inspection and walkthrough to ensure your satisfaction of the project, along with showing you how the windows work and answering any questions.

Pros and Cons of Insert Window Replacement

Just like full-frame window replacement, insert window replacement has its own set of pros and cons. Here are the pros and cons to consider if you’re thinking about using this type of window installation:

Insert Window Installation Pros:

  • High quality insert replacement windows are very energy efficient, especially when installed correctly. Choose vinyl replacement windows that are certified by Energy Star for best results.
  • Insert replacement windows are an effective method to update old windows of the same style. They can also transition into a new window style if the frame opening is the same size. For example, a picture window can become a bay or bow window if the dimensions are the same.
  • Insert replacement window installation can be completed as quickly as one day, assuming the entire process goes smooth and there are no problems discovered with frames, sills, etc.
  • Vinyl replacement windows offer a variety of shapes, styles, and sizes to customize curb appeal. Homeowners can find a variety of vinyl frame colors, grid systems, and decorative glass options.

Insert Window Installation Cons:

  • Choosing mass-produced insert windows from the home improvement store can result in lower quality materials and lower performance standards.
  • Low quality replacement windows can discolor from the sun and potentially peel or warp.
  • Some homeowners may attempt the DIY route with insert replacement windows, especially since they are much less labor intensive than their full-frame counterparts. However, this can dramatically reduce the performance of the window—especially if the homeowner does not have experience with window installation.
  • Attempting DIY installation can void the window’s warranty, leaving any performance failures, mechanical issues, etc. at the expense of the homeowner.

    A Word on Window Warranty and Insurance

    While we’ve talked about window warranties before, it’s important to keep this topic in the back of your mind when you’re working with window installation companies. Window companies that back their products with a warranty will guarantee performance and cover many components and aspects of the window, including labor and installation. Always ask to review the window warranty for installation and ask any questions before the projects begins.

    It’s also important to hire a window company with insurance. If the window company is not insured, the homeowner may have to pay any bills in the event of an accident. Make sure that you verify that your window company in fact has insurance, and do not hire out-of-town contractors without a physical address to an occupied office. Unfortunately, scammer contractors can go from town to town, claiming to offer window installation services and disappear into the night with your deposit.
