## The honest read

GBA Window Cleaning is a Cape Cod crew run by Gilmar Borsatto, and what jumps out first is the consistency: Google shows a 5-star average across 99 ratings, and every one of the 70 reviews on file here matches that line, running back to 2022 without a single negative one.

The deepest part of the record is repeat business. Several customers describe using Gilmar's crew for a decade, and others for five-plus years running, which only holds up if the work keeps landing. The specifics repeat: the team shows up on time or early, moves fast through a whole house, and leaves it clean — one reviewer describes seven or eight workers finishing roughly 40 windows in about ninety minutes, and several others mention shoe covers worn inside. The work isn't just glass, either — skylights (inside and out) and gutters come up again and again as part of the same visit, alongside screens, sliders and doors.

In a 2022 review, one Wellfleet customer described getting a quick estimate during the height of the summer season and having the crew wash the whole house's windows soon after, fitting the job into their lunch hour — a sign the company works the outer Cape as well as the closer-in towns.

Pricing is the one thing worth asking about upfront. Most reviewers who mention cost call it fair or reasonable, but one flagged a job needing a ladder to a fourth floor as pricier than expected — worth confirming before booking anything beyond a standard single-story pass.

For a window, gutter, or skylight cleaning on the Cape, GBA's history is about as clean a track record as this trade produces — the main thing to nail down going in is what the quote covers if your job has real height or scope to it.

**Strengths:**
- Consistent 5-star reviews — 70 collected, none negative
- Long-tenured customers — several cite a decade of use
- Fast, large crews — teams of 7-8 finish full houses quickly
- Full exterior-glass service — windows, screens, skylights, and gutters

**Concerns:**
- Top-floor pricing — one reviewer called a 4th-floor job pricier
