"They were great. Definitely worked hard and the house looks great. I hired them for a deep cleaning after renovations so I paid more than their asking price. They was constantly working and because of the amount of dirt from the renovations it took 5 hours to complete. I will be having them back."

Window Cleaning FAQs, answered by experts

Professionals use high-pressure steam cleaners, brushes, and specialized cleaning solutions for effective results.

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

You should avoid using abrasive materials and harsh chemicals when cleaning windows. Abrasive tools like scrubbing pads, rough cloths, or steel wool can permanently scratch and damage the glass. Harsh chemical cleaners containing alcohol or ammonia can damage window treatments, frame materials, and special features like tinting. It is also best to use distilled or filtered water instead of hard water, which can leave spots or streaks. For best results, use a clean microfiber cloth to wash the glass and old black and white newspapers to dry it without leaving streaks.

Absolutely! We prioritize using eco-friendly, non-toxic products to ensure your home's and the environment's safety.

The best way to clean outside windows is by using a garden hose. Start by spraying the windows with a high-pressure stream to clear off loose dirt and grime. Then use a mixture of hot water and dish soap and scrub the windows with a sponge. Rinse off the soapy water with the hose. Before you finish up, spray the windows with a solution of vinegar and water and wipe them down with a microfiber cloth.
