"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."

"I really appreciated the time they took to give me a fair estimate for my house windows. They got here on time for my scheduled appointment and got to work! I was really surprised at how dirty my windows were and amazed at how clean they look now. I am very happy with the quality and friendly service Phil and Seth provided. Can not wait for them to come back for my monthly appointments!"

Hi! My name is Adriana Moron. I moved out here from Arizona 2 years ago. I was working a construction job doing hard labor non stop. I needed a change to be able to do what I always wanted. I want to paint purses, put my art out there in fashion. I love to clean. I say Clean space is clear mind. I’d be happy to clean your space no matter how dirty.

Window Cleaning FAQs, answered by experts

You can use hot, soapy water, white vinegar, rubbing alcohol, window cleaner, nail polish remover, WD-40, and cooking oil to remove glass labels. You can also apply heat with a hair dryer or steam cleaner. Use a plastic scraper or credit card to remove the adhesive, as a razor blade can permanently scratch your glass.

A handy hair dryer will quickly remove condensation from your window, but it’s only a temporary fix. The hair dryer maneuver will not repair the root of the window fogging problem, which is likely a broken window seal. If you need to defog the window quickly, such as if guests are coming over, use the hair dryer. However, for a permanent solution, defogging the window or replacing it are the only options.

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.

Long-handled telescopic brushes are the best way to clean the outside of a house without a pressure washer. There are even special attachments for cleaning the outside of windows. Use a gentle cleaning solution for both the roof and siding to avoid harming the finishes. Be sure to rinse the area thoroughly with a garden hose after scrubbing.

Professionals use advanced, eco-friendly products that ensure effective yet safe cleaning.
