Three hundred and ninety-seven reviews in roughly two years, 125 of them in the last six months alone — Full Clarity Window Washing is running a high-volume seasonal route across the Merrimack Valley, and the machine behind it is what customers keep describing. The pattern in the reviews is process, not craft mystique. Quotes come back the same day, sometimes without a visit; contracts get accepted electronically; the schedule arrives by text with arrival reminders. One customer summed up the whole transaction as quote, contract and schedule all on the day of the request. Crews of two or three arrive named — Bryan, Sean, John, Jonathan — and the small courtesies come up constantly: boots off at the door, furniture worked around, the site cleaned up. The work itself is windows in and out, screens, sills and skylights, and the technical detail reviewers volunteer most often is the screen-washing machine hooked up outside rather than a brush and a bucket indoors. That same customer mentioned a one-week warranty and a crew that came back a second time over a single streak. Skylights come up repeatedly as the job people specifically call about. One homeowner also had gutters cleaned on the same visit. Price reads as the other draw. Reviewers describe estimates as affordable and reasonable rather than cheap, and the company sells repeat membership — one customer got fifty dollars off by booking next year's cleaning on the spot, another said signing up locks in next year's price. Nobody in the record complains about what they were charged. Where it slips is scheduling and follow-up under that volume. In July 2026 a customer who had booked a month ahead wrote that the crew never showed on the date scheduled, and told other homeowners to go elsewhere. In August 2026 another customer, otherwise happy with the job, said two cellar windows were missed and that repeated attempts to reach Bryan afterwards went unanswered. Two complaints against 125 recent reviews is a small share, but both are about the same thing — what happens when something needs fixing after the truck leaves. So: a strong pick for a straightforward residential or storefront window cleaning where you want a fast quote and a firm date, especially if screens and skylights are part of it. Before you book, get the appointment date confirmed in writing, ask what the warranty covers and how to reach someone if a pane gets missed — and be clear whether your quote includes screens, sills and any gutter work.
Beautiful job cleaning our windows!
Excellent service! On time, courteous, and clean! Will definitely use them again!!
Great communication and really nice end result! Getting a quote and scheduling were both super easy; great customer service all around. Very happy we went with Full Clarity. The employees that did our windows did great work and were very polite and respectful. We were very pleased with our experience and will certainly hire them again for future service. Highly recommend!
Full Clarity did a great job on our very old and dirty windows! They were polite and professional. Gave us a quote and scheduled in a timely manner. We would definitely use them again.
The 3 person crew were going to be late, but they made sure to relay this to me on a timely basis. They worked tirelessly thru the day, leaving my windows spotless. We went thru window by window, the team leader and I and if there was a spot he took care of it. I will use this company again!!!
