Six hundred sixty-three Google ratings, a flat 5.0, and a Cape Cod summer's worth of them landing in one stretch across June and July: Duchesney Window Washing is who Barnstable County books when the salt haze finally becomes unbearable. Angi carries a 4.9 across another 103 ratings, and the written history goes back to 2021.
The job barely varies from review to review, which is its own kind of endorsement. Two people arrive when they said they would, pull the screens, wash inside and out, put everything back, and go. A July 2026 customer timed it: under three hours, screens off, both sides done, everything replaced. Another wrote that when the crew finished, they walked back through every window individually, in and out, to check. One homeowner said the glass came out so clear she thought the bedroom window had been left open.
The work runs well past glass. Customers this summer describe screens and floor-to-ceiling porch screens, skylights done inside on request, gutters cleaned, solar panels washed, patios and patio furniture, and multi-day exterior packages. The soft-wash side has its own following: in May 2026, a homeowner with old, brittle, moss-covered cedar shingles said the green algae came off and the wood went back to a natural color, and a June 2026 customer had cedar siding and a roof washed and said the siding finally matched all the way around.
Small operational habits show up in the write-ups. A May 2026 customer having a roof washed noticed one worker constantly watering down the plants and the sides of the house as protection while the other worked. Another said a moss-covered patio and a second roof added mid-job were handled without hesitation. Repeat business says the most: a Provincetown HOA books them year after year for the owners there, and several June 2026 customers were on their second season.
Which makes the one bad review worth reading closely. In May 2026, a customer wrote that the crew was asked to cover a pond and did not, that their fish died, and that half the house was missed. That is precisely the failure the plant-watering reviewer describes them avoiding, so settle it before the truck arrives: ask how ponds, plantings and anything else within reach of runoff will be protected, and get the full list of surfaces in writing so nothing is skipped. Separately, a June 2026 customer who was otherwise pleased said the skylights could have come out better.
For seasonal window and screen cleaning on the Cape, this is about as established as it gets — hundreds of ratings, a fresh wave of them every summer, and prices customers repeatedly call reasonable. Nail down the surface list and the protection plan for whatever is living in the yard, and the rest reads as routine.
