"Remember the days when you could trust a contractor to do an amazing job, You didn't need an estimate because you knew they would never rip you off. Their work and attitude were always exceptional. Well, the days of old are back with Spyglass. He is on time, first class, fabulous work and trustworthy. He does our window cleanering, gutters and special projects we need as elderly clients."

Window Cleaning questions, answered by experts

Use of harnesses and ladders ensures safe roof access.

To clean an estate, start by locating all important documents, which you’ll need to sort through. Have the mail forwarded, change the locks, and take inventory of the entire estate. Once you know what you’re dealing with, create a plan and a timeline for the cleanout. Start clearing out rooms and sorting items to donate, sell, or get rid of. Finally, deep clean the property.

Hot water removes grime more efficiently than cold water and evaporates more quickly so that your windows will dry faster. However, you may want to use cold water instead if your windowsill paint is chipping or peeling because heat can worsen this condition.

Soot can be harder to remove compared to other types of stains given its acidic nature. It can also cause underlying paint to peel off during the cleaning process. If your soot issue is a result of smoke damage, it’s recommended you call a pro to help remove it versus doing it yourself.

Most jobs take 2-8 hours, depending on the number of windows, height, and difficulty of access.
