Here's a list of important steps to take before buying your new windows: Map Out Your Exterior - This will help narrow down your options and will ensure that your windows work with your home not against it. Remember the Kids and the Canines - Children have the tendency to get their small fingers caught in window hinges and both pets and children can accidentally apply enough pressure to open certain styles of windows. Speak to a Realtor - If you know selling your home will happen at some point in the future, it’s important to choose windows that will increase your resale value.
