Homeowners Guide: Installing Replacement Vinyl Windows in Dallas

Replacement windows in Dallas are critical for building a comfortable, energy-efficient house that looks good and saves you money. They could even pay for themselves over time. Replacement windows may radically improve your house’s energy efficiency while enhancing your property’s value and exterior appeal. 

Some of the advantages of vinyl replacement windows in Dallas are listed below. For more information, visit us at

  • Energy efficient: Vinyl window frames with sustainable foam boost the R-value of your windows, making them more energy-efficient. Heat loss and infiltration by convection, conduction, and emission are further reduced when window glass is strengthened with an inert gas fill.
  • Ultraviolet protection: The unique glass in replacement windows is unaffected by the scorching Texas sun. 99.9% of damaging UV rays are blocked from entering your house by a translucent, suspended film layer.
  • Noise reduction: Wet glazing, triple-fin weather stripping, insulating foam, and triple glass seals, combined with exceptional sealing technologies like wet glazing, triple-fin weather stripping, insulating foam, and triple glass seals, help keep the noises from the surrounding at bay and prevent trapped condensation from necessitating costly window glass repair in the future.

How Are Vinyl Replacement Windows Installed?

A proper vinyl window installation necessitates two important things. The first step is to schedule the job for a warmer season. Cold weather is significantly more of a concern than warm weather if the job takes longer than anticipated. Second, take precise measurements and order windows that match those measurements as closely as feasible.

Aside from those critical aspects, unboxing and inspecting each new vinyl window before starting the process is a smart idea. Ensure the windows are in good functional order and free of any shipping damage or flaws. Remove the vinyl coverings that snap into the jamb tracks of the new windows now since here is where the screws to fasten each new window will go.

Step 1: Remove the old window

Removing the old window is the first stage in vinyl window installation. For safety’s sake, lower both sashes to their lowest positions.

Pry the window stops (the thin pieces of wood that keep the window sashes in place) off the sides and top of the window with the prybar and hammer from the inside. The outermost stops, and the windowsill should remain in place. Pull the window sashes out of the window after removing the stops. If the stops are difficult to remove, consider cutting them off using an oscillating multi-tool.

Step 2: Prepare the window frame for the installation of vinyl windows

Examine the existing frame for major flaws such as rot, mildew, splitting, or any condition that may necessitate a more in-depth treatment once the original window sashes have been removed. A mildew remover can frequently suffice to clean the frame of mildew and other dirt and filth.

The frame must be level and plumb, but it’s not nearly as important as it is for it to be square. Measure diagonally opposed corners using a tape measure to verify they’re within 14 inches of each other. If not, you may need to remove the window trim and use shims to modify the actual frame.

Step 3: The replacement vinyl window should be centered in the opening.

First, make sure the window fits in the opening by testing it. Remove the window after double-checking the fit before squeezing a bead of caulk inside the outer part of the window stopper.

Place the replacement vinyl window in the opening and center it, allowing room for shims and insulation on each side. To guarantee that the window is centered, use a tape measure to ensure that the reveal is uniform on all sides.

Step 4: Use shims to align the window correctly

Place shims beneath the window to elevate and level it in the window opening with the sashes closed and fastened. If the window frame is significantly off of level (as is common in older homes), follow the window slope to ensure that the window does not seem crooked when done.

Shim along the top, bottom, and center of the window’s sides. The shims should be snug enough to keep the window in place but not so tight that they obstruct its functionality. 

Step 5: Insert a 2 ¼-inch  screw into each window frame corner

Ensure the shims are behind these holes before screwing from inside the window, through the shims, and into the frame. Drill a hole through the shims to prevent them from separating, then screw a 214-inch screw into the frame from the interior of the new window.

Step 6: Insulate around the window

There’s a purpose for the gaps on all sides of the window: insulation. Fiberglass insulation isn’t suitable for this project since pushing the batting into the crevices compresses the fibers and makes it impossible to operate. Foam, on the other hand, is effective.

Tape is used to cover the inner perimeter of the window frame. Use a small amount of expanding foam to create a foam barrier between the replacement window frame and the current window frame. Allow it to cure before cutting away the extra foam and removing the adhesive. 

Step 7: Window Caulk and stop should be installed

Finally, install new window stops on the window’s interior to complete the look. Ensure that the stops are thick enough to fill the space between the replacement window and the original frame for a polished look.

Latex caulk will cover any gaps or seams in painted projects. Squeeze the caulk into each seam with the caulking gun, then smooth it out with a fingertip moistened in a wet paper towel. 

Step 8: Match the window trim with the frame by staining or painting it (optional)

Vinyl windows come in various hues, but the most common is white. If you’re replacing a natural wood or painted window with a new vinyl window, you might choose to paint the trim to match the new window. However, this may be a large undertaking because the baseboard trim, door moldings, and crown molding can be painted.

Is It Possible to Install Replacement Windows From the Outside?

In many situations, windows may be placed at least partially from the outside. Each home is unique; some aspects of your window openings may demand conducting all or part of the replacement window installation inside.
