## The honest read

Chatham Window Washing is a one-owner Cape Cod outfit run out of Harwich by Mark McLaughlin, cleaning windows, screens, storm sashes and skylights for houses and small businesses from Chatham down through Harwich, Orleans, Dennis and Brewster. The company describes its method as a proprietary cleaning solution paired with an ultra-pure water system.

For several years, the reviews told one consistent story. In 2024 and 2025, customers described a crew - Mark paired with Kevin, or Diedra, or Mike - arriving on schedule and working through sills, tracks and frames that "many companies overlook." One reviewer, writing in October 2024, said she'd used the company annually for three years and called it prompt, professional and reliable; another, that September, praised Kevin for returning two days later just to fix a loose screen. A 61-window house, washed inside and out in three hours, earned a five-star review in July 2026.

That consistency has slipped since late 2025. Of the three reviews posted since February 2026, two are negative: one customer says she got no price up front and was shocked by a $500 bill; another, in April 2026, says Mark left for Florida mid-job and hung up when they asked for their $700 back instead of returning to finish. A December 2025 review describes a solo visit, without the usual crew, that left several windows untouched or smeared. The Better Business Bureau currently grades the business C+ for not responding to one complaint, though its own page carries no review text or star average of its own. A single review from 2021 also describes lingering water spots the owner blamed on hard water rather than fixing.

The strongest years here look like a return-every-year, ask-for-Kevin outfit; the last several months look like something has slipped. Get a firm price before the crew arrives, and confirm whether Mark is bringing a team or coming alone.

**Strengths:**
- Repeat customers — several return annually citing reliable work
- Detail-oriented — reviewers cite clean sills, tracks and frames
- Responsive follow-up — returned to fix a loose screen at no charge

**Concerns:**
- Billing dispute — 2026 review reports a $500 charge with no upfront quote
- Refund refused — 2026 review says owner left mid-job and wouldn't repay $700
- Solo visit incomplete — Dec 2025 review reports windows left dirty
- BBB grade C+ — unresolved complaint on file

**Where sources disagree:**
- Google reviews (23 ratings, 4.2 stars) run mostly positive while BBB grades the business C+ over one unresolved complaint that BBB's own page does not detail
