Horrible experience with this contractor. Left dry concrete splatters all over the front door and wall of our house. Said he'd add a step after raising our front porch 4" and never did. During estimate said they'd power spray the existing porch clean and add a concrete adhesive before pouring the new porch but did no such thing and even poured over leaves and dirt. Also said they would put a sealer down over the porch and patio and again, never did. Three years later we're getting diagonal cracks in both the porch and patio.
