Replacement Window Installation Options
When it comes to home improvement projects, few choices can have as significant an impact as replacing your home windows. However, unlike many other improvements that can be accomplished with some effort and a good plan, window replacement demands substantial work and a deep technical understanding.
Replacing your windows is a complex task that requires careful consideration. You'll need to determine the type of window that suits your needs, create precise plans tailored to your window's size, and select the appropriate materials for a seamless fit with your replacement window.
There are two primary options for window replacement: full-frame (nail fin) replacement and block-frame (retrofit) replacement, each with its own advantages. Continue reading to discover which option best suits your home's needs.
Full Frame Replacement
Using a full-frame replacement window, as the name suggests, typically involves replacing the entire window unit, including the existing frame, sashes, and screen. Depending on your current window, this process may require tools such as a utility knife, screwdrivers, a pry bar, hammer, putty knife, and even a circular saw. For this type of installation, we generally opt for windows equipped with a nail fin.
Nail fin windows are commonly utilized in new construction projects or any remodel where the wall's framework (studs) will be exposed. These windows feature a thin piece that extends from the window itself, wrapping around the outer edges of the window frame. When installed on a new frame, this nail fin securely attaches the window to the house's studs, remaining concealed between the interior and exterior of your home.
The installation of a nail fin window can be labor-intensive and may necessitate the addition of a new window frame or the removal of siding to facilitate attachment to the studs. If you're considering installing a nail fin window on an existing wall, especially in an area where replacing stone or brick exterior is required, the task may be time-consuming and complex.
However, it's essential to note that this method provides the advantage of maximizing window size and offering superior protection against water intrusion, making it the best choice for those seeking both a larger window and optimal water resistance.
Block-frame Replacement
Replacement block frame windows, also known as pocket replacement windows, offer a distinct approach compared to full-frame replacements. These windows are designed to fit within an existing window frame. While the existing window sashes and exterior stops must be removed to accommodate the new window, pocket replacements allow homeowners to retain the original frame, trim, siding, and casing.
Similar to full-frame replacement, the condition of the wall exterior surrounding the window opening impacts the pocket replacement process, albeit with fewer steps. Instead of completely removing the existing window, it is typically cut out using a reciprocating saw (Sawzall).
The replacement window is then inserted into the opening and secured to the existing frame with screws, with foam insulation filling the space between the window and frame. Caulking ensures water intrusion prevention, and trim is installed to give the window a finished appearance.
In most cases, some minor touch-ups may be required on the interior, such as drywall and paint, and possibly on the exterior, including siding or stucco. Generally, block frame replacement is a simpler and less invasive method than full-frame replacement, making it a cost-effective installation option.
Which option is right for you?
Each option has its own set of advantages and disadvantages.
If your budget permits, we typically recommend considering full-frame replacement. It offers the advantage of a larger window for the opening and provides superior protection against water intrusion. However, it involves more extensive labor and materials, making it generally pricier.
For the block frame option, some maintenance is needed with periodic caulking, and these windows may be slightly smaller due to their design. If cost is the primary concern, the savings associated with block frame replacement can be quite substantial.
