Even Flow Pressure Washing

Even Flow Pressure Washing works out of Princeton, and the thing that keeps coming up across more than a hundred reviews is the roof: owner Rob specializes in a soft, low-pressure wash that pulls years of moss, algae and lichen off shingles without pressure-blasting them. One customer says he removed 20 years of algae and mildew buildup from their vinyl siding and roof; another had a shaded, moss-heavy roof scheduled on short notice and called it the best value they got even though it wasn't the cheapest quote. The record behind that reputation runs deep — 102 reviews stretching from 2020 through this year across six platforms, rated 4.9 to 5.0 stars on Google, HomeAdvisor, Angi and Thumbtack, and the recent run keeps the same shape: 13 reviews in the last six months, none negative. Reviewers describe a predictable process — Rob, often with an assistant or a teammate named Alyssa, does a walk-through, itemizes what needs doing and what doesn't, and quotes a price before starting; several say he pointed out problems washing wouldn't fix rather than oversell the job. More than one homeowner has called him back for a second job years later. A 2026 Reddit thread in r/WorcesterMA name-checked the business the same way — a low-pressure roof cleaner working out of Princeton. Not every account is spotless: in a 2022 Angi review, one customer rated the roof cleaning 4 stars and said the job felt rushed for their heavily wooded, debris-prone property, and thought it could have been done more thoroughly. Even Flow is the call for roof, siding, deck and gutter washing done carefully rather than fast. Before booking, it's worth asking how Rob would handle a lot with heavy tree cover, given the one review that flagged exactly that.
