Editorial summary
Mast Construction Corp is listed in Portland at 160 St John St and is indexed here as a foundation repair contractor. Google classifies the business as a construction company, which is a useful clue that the profile may cover more than a single narrow trade, but the supplied service list still only names foundation repair. The record includes a phone number and a strong-looking Google rating of 5 stars from 5 reviews, yet no website, service-area text, or years-in-business detail was provided. That leaves the listing with a decent amount of local visibility but only modest background context. The related search topics supplied with the record point toward common homeowner searches such as sagging floor repair, crawlspace repair, and fixing sagging floors from below, but those terms are not presented as confirmed services here. As written, this directory entry should be treated as a concise foundation repair profile with limited public-facing detail.
