"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!"

Window Cleaning FAQs, answered by experts

One of the best professional cleaning solutions that won’t leave streaks is one gallon of distilled or bottled water mixed with 2 to 4 teaspoons of dish soap. Apply using a sponge in a figure-eight motion, and then use a squeegee to remove the majority of the water and soap. You can finish drying with a piece of old black-and-white newspaper to remove any residue for a streak-free clean every time.

Solar screens are low-maintenance but benefit from occasional cleaning with mild soap and water. Avoid using harsh chemicals or pressure washing, as these can damage the mesh. Inspect screens annually for tears or loose frames to maintain performance. In dusty or coastal areas, more frequent cleaning may be necessary to prevent buildup.

Whether you tip before or after a carpet cleaning depends on when you’re available. If you’re home when they finish up, you can give them their tip after. However, if you need to leave before they’re done or if you won’t be home at all, you can prepare the tip beforehand and leave it for them in an envelope.

Professionals clean window screens the same way a homeowner can—by removing the screens and cleaning them with a sponge. A window cleaning pro may come with better equipment, like a high powered wet/dry vacuum or pressure washer to speed up the process and achieve a deeper clean.

Professional cleaning offers deeper sanitization, reaches grout inaccessible by home tools, and restores tiles without causing damage. Technicians have expertise and equipment that ensures long-lasting cleanliness and improved aesthetics.
