Using common carpentry tools, you can install a sash kit or window insert from inside your home without destroying the surrounding interior molding or exterior casing.
If you have the right tools and tips, installing a window yourself can be a weekend project. Whether you're replacing a damaged window or just want a new look, we will show you how to get the results you want without calling in help from a professional. Check out our steps below and get started today.
Installing a window yourself will only work when the replacement window is the same size and shape as the old one and when the existing window opening is square. To determine whether your window opening is square, measure it diagonally one way (from the upper left corner to the lower right corner) and then the other (from the upper right corner to the lower left corner). If the opening is square, the two measurements will be the same, give or take 1/8 inch. The slightest deviation from square can prevent the sash from closing and the weather stripping from sealing properly. If that happens, you'll be stuck with drafts, condensation, and high utility bills.
