Editorial summary
William Mushero Inc. is listed at 7 Summer St in Oakland, Maine, with a phone number shown and a 5-star Google rating from 4 reviews. The available business data identifies the company as a general contractor and places it in a foundation repair directory category. Beyond foundation repair, the record does not provide a website, service area, years in business, financing, or free-inspection details. That limited profile means the safest read is simple: this is a local Oakland listing with a narrow confirmed service line and a small but perfect Google rating. Search interest around sagging floors and crawlspace repair is relevant to the category, but those services are not explicitly listed here, so they should not be assumed. For homeowners comparing options in the area, the key facts are the Oakland address, the listed phone, the 5-star review score, and the confirmed foundation repair service.
