"Excellent experience from start to finish! The team was professional, friendly, and arrived on time. They did an amazing job cleaning our windows—they're absolutely sparkling, and I didn't realize how much brighter the house would look afterward. They were careful, efficient, and left everything clean when they finished. I highly recommend this company to anyone looking for quality window cleaning and outstanding customer service. I'll definitely be using them again!"

"The team was very courteous, and professional. They did a very good job on the windows (I hate cleaning glass) so I really appreciate when someone else is doing the work. Their pricing is also competitive and fair. I will be hiring them again when I need windows cleaned."

Window Cleaning FAQs, answered by experts

Professional window cleaners typically use either a white vinegar solution or a commercial hard water stain remover to clean hard water stains on windows. A common vinegar solution for this purpose consists of one cup of white vinegar mixed with a gallon of distilled or bottled water. The pro will spray the mixture and lightly scrub the window with a scrubby pad before cleaning with a standard cleaning solution. Alternatively, they may use a commercially available hard water stain remover and a scrubby pad, followed by a complete cleaning.

Post-construction cleaning services typically include debris removal, dusting, vacuuming, wiping and sanitizing surfaces, window cleaning, and floor polishing. Depending on the scope, services may also extend to duct cleaning and general interior cleaning.

Access to professional tools ensures streak-free finishes and safety in hard-to-reach areas.

The simplest way to clean stained glass windows is by using warm distilled water and a damp cloth. Distilled water won’t corrode the stained glass or leave residue behind. Avoid using cleaners with alcohol or ammonia. However, you should only clean when necessary. Stained glass windows are fragile, and excessive cleaning could cause fading, weakening of the solder, or other damage.

A professional cleaning service generally takes a few hours, typically between 2 to 4 hours, depending on the property's size and the severity of any stains. Keep in mind that wet cleaning methods will require additional drying time.
