Before you begin the installation process, you will need to check the window opening size to ensure you've chosen a window that will fit snugly in the available space. Measure the length, width and height of the opening. Your chosen window should fit within the opening with space left around the exterior to allow for the installation of flashing. You should also check that the opening is plumb, level and square, with no more than a one-eighth-inch disparity over the measurement. If the window opening is off centered, you'll need to place wooden shims at the corners to level it out for the window installation.

The next step for installation is to prepare the opening for flashing. The house wrap covering the window opening must be cut down the center and then folded inward and stapled to the interior wall. Create a top flap using a trapezoid shape with 45-degree angles, and then fold the house wrap upward and secure it with tape. With the wrap secured, you can begin covering the window sill with the flashing material. Flashing helps to keep water from seeping through the sill edges into the house. The flashing material can be secured using a staple gun or roofing nails.

With the flashing in place, you must next fit wooden shims at the side of the window jamb to level out the window. Then you'll apply sealant to the sides and top of the opening. Slide the window into place from the exterior of the building, and then nail the top corner of the window in place to provide a temporary hold.

Overlap the top piece of the side flange over the bottom piece to ensure that any moisture flows over the seal. Check that the window is plumb and square again and insert side shims where necessary to center the window. Fasten the window in place through the indicated fastener holes on the exterior of the building. Apply side flashing that extends to the height of the windows plus two inches at the top and bottom, and then apply sealant to the top of the window to hold the drip cap in place. Place flashing along the top of the window overlapping the side flashing. Fold the taped house wrap downward and tape it in place.

Next, cut the wooden shims flush to the interior of the window, and then fill the opening at the side of the window and the jamb with low expanding foam. Place backer rod material over the foam and into the exterior opening between the window and the jamb, and then seal the exterior edges of the window to complete the installation process.

Andersen windows price estimates are determined by the window opening size and the window type installed. To get a windows estimate that takes into account the windows cost and labor cost, you should consult a contractor found through the QualitySmith listings. Once you know the price, you can proceed with the installation following the Andersen windows installation instructions that comes with the windows or hire the contractor to handle the installation for you.
