"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

For a standard 1,000-square-foot home, you should expect your window cleaner to take between 1 and 3 hours to clean all of your windows. Of course, the size of your home and the number and size of the windows you have will play a role in the timeline. Certain styles of windows—like picture windows, which have no moving parts—also take less time to clean.

No, but removing window screens will achieve a deeper clean. If you aren’t sure how to remove your screens, you can still clean them while in your window. You can follow the same cleaning steps, but you may not be able to get into corners or struggle to clean the entire screen if the window is up high.

Luckily, glass block windows need minimal maintenance. Other than regular cleaning, the only maintenance involved in having a glass block window is inspecting for cracks every year and applying sealer to the mortar joints if the blocks are set in masonry mortar. Glass block windows hold up well against wind and moisture better than traditional windows and are not prone to rot.

Hard water stains can permanently damage your glass if left untreated. The minerals dissolved in the water can etch the glass, causing long-term damage and affecting the overall integrity of the surface. Luckily, it is pretty simple to remove hard water stains by using vinegar, baking soda, or commercial cleaners.

Hard water stains are caused by hard water. Hard water contains a lot of minerals, like calcium and magnesium. When water on your glass surfaces dries out, the minerals stay behind and stick to the glass. This results in a residue that looks like white cloudy or streaky spots. Call a pro to install a water softener to banish hard water problems.
