"The owner, Ben, did an outstanding job cleaning our residential windows (his company also does commercial window cleaning). To date we have used him twice. Sea-Thru Window Cleaning communicates very well with their customers - before, during and after. The result is appointments are kept and reminders for future cleanings are provided. I highly recommend Sea-Thru Window Cleaning - you will be amazed of the results."

"Tara is amazing! She’s very reasonably priced and does a great job. She was in and out quickly and was very thorough; my mother saw her in action and referred to her as “the cleaning tornado” from then on. She was always personable and had no qualms working around people visiting or the dog following her around. I would very highly recommend her!"
