Renew Power Wash

Renew Power Wash is a one-person, family-run power washing outfit in Chelmsford, Massachusetts, and Alan Hamer, the owner, is the name that shows up in almost every review. The company says it's family-owned and serves the Merrimack Valley, handling houses, decks, fences, roofs and patios. The record is short but consistently good: 17 Google reviews on file, every one five stars, adding up to a 4.9-star average across 41 ratings. Several customers say they've called Hamer back repeatedly, one used him three times over six years, another twice over three years, and the recurring theme is that he tells people what actually needs doing rather than upselling a bigger job. One homeowner, in a 2021 review, credited him with reviving a pool deck that every store-bought chemical had failed to fix, without resorting to a damaging acid wash. There's no complaint on file to weigh against that. The closest thing to a caveat is that a few reviewers mention working around his schedule during busy stretches, one squeezed in before an event, another got accommodated ahead of Mother's Day during peak season, worth keeping in mind if you're on a deadline. The site also lists an "Approved Massachusetts Pro" affiliation, a self-reported badge rather than a state license (pressure washing isn't a licensed trade in Massachusetts). For a homeowner in the Merrimack Valley who wants a house, deck, fence or roof washed, especially ahead of a sale or an event, the reviews point to a small operation that shows up, does the specific job asked for, and charges a price customers repeatedly call fair. Book ahead if it's peak season.
