"Recommend Joslin & Co for window cleaning. Hands down the best not just for service but the great customer service as well. You can tell Nico takes great pride in his work with the care for the building and his customers! He is a really cool down to earth guy yet still professional and quick and efficient in his services! 10/10 in my book."

"This company company was SO amazing to work with. When I first asked for a quote to clean my patio, a representative of the company, named Carmen, had me send pictures of the space and gave me a formal quote. Carmen was always attentive to every question I had about the process to clean my patio and always gave me a straight answer. Wandel, the cleaner, was on time for the job and power washed the fence, windows, cement patio and did yard/waste removal. Handel even came back for a second day to continue to thoroughly clean that patio upon request. The patio space looks beautiful now. I highly recommend using Square Services!"

"I use Camilla often. She takes her time and thoroughly cleans whatever rooms I ask her to do she even cleaned my fridge one day and it looked brand new. She is very flexible and caters to your schedule. I trust her 100% there have been times when my whole family is at work and she has been in home alone cleaning. Very professional with a touch of love. Only person I let clean my home."

Window Cleaning FAQs, answered by experts

Use of harnesses and ladders ensures safe roof access.

Time varies by number and size of windows but usually 2-4 hours.

Unless it’s written into the purchase agreement, there’s no legal obligation that a house you’ve bought has to be clean before you move in. The previous owner is generally required to sweep the house, but that doesn’t guarantee everything will be spotless upon your arrival. If possible, discuss the cleaning requirements with the real estate company before moving in.

A standard professional cleaning of an entire apartment typically takes 2 to 3 hours. However, the timing varies depending on the size of the apartment, the number of people and pets that live in it, and how frequently it is cleaned. A deep cleaning typically takes 4 to 6 hours.

The best homemade cleaning solution for windows is one gallon of warm, distilled or bottled water mixed with five to ten drops of liquid dish soap. This is what professional window cleaners typically use when they make their cleaning solutions. Using bottled or distilled water will help avoid hard water stains after cleaning, and the soap will cut through grease, smudges, and debris on your glass.
