William L Schreiter

William L Schreiter works out of an address on South Riverview Street in Haverhill and turns up in public records the way a long-running one-man general contractor does: as a name on permits. BuildZoom's file holds seven of them, from a 2022 load-bearing wall opening in Groveland and commercial tenant fit-ups in Methuen back to shed reroofs on the Cape in the late 1990s, and it lists kitchens, bathrooms, basements, whole-home remodels and additions as the work on offer. What is absent is any customer voice. No reviews have been posted about him on BuildZoom, and no other directory carries the business at all, so there is nothing to say about how the finished work lands with homeowners. BuildZoom does list a Massachusetts home improvement contractor registration (#204509) and a construction supervisor license (#CS-045263), both shown as active. That is BuildZoom's own record rather than a check against the state, so treat the numbers as a starting point: verify them yourself at Consumer Affairs and the Department of Public Safety, and ask for two or three recent local references before going further.
