"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."

Window Cleaning FAQs, answered by experts

Yes, utilizing green solutions that are safe for both homes and the environment.

Clean with non-abrasive cleaners and a soft cloth, avoiding ammonia-based products that can degrade the film.

The easiest way to remove window decals is to soak the area in hot, soapy water. Let it sit for 15 minutes before scraping it with a plastic scraper or the edge of a credit card. You can also remove window decals with white vinegar, rubbing alcohol, or applying heat from a hairdryer or steam cleaner.

Clean the outside of your home at least once a year. If you live in an area with salty sea air, high levels of pollen, or an abundance of leaves in the fall, it's helpful to wash it at least two times a year. Frequent cleanings will allow you to remove debris and pests before they flourish into infestations, or cause mold and mildew.

Mold on windows forms due to excess moisture from condensation, poor ventilation, or leaks. Cold glass surfaces can attract condensation, especially in winter. High indoor humidity, lack of airflow, or dust accumulation are also contributors. To prevent mold growth, improve ventilation, regularly clean sills, and consider using a dehumidifier or sealing any leaks.
