If your street is still filling in, you are exactly who this page is for.
A new house shouldn't come with a fence treated as an afterthought, thrown up fast to close out somebody's punch list. We already work in Mont Belvieu rather than showing up when a subdivision needs one more contractor, and your line gets the same attention whether the rest of the street is finished or not.
Much of this area sits on heavy clay that swells when it is wet and shrinks when it dries, and that movement is what leans a fence years later. Posts get set for the soil that is actually on your property, not to a generic spec, and on wet ground we would rather wait a day than set posts in mud and watch the fence lean two summers on.
Your property gets measured and the number comes to you in writing before anything starts.
