"I was very pleased with the service Molly maids provided! They were early to the appointment and did an excellent job despite the fact that our power got turned off a day early. The girls that came to the house were very nice and professional. I'm thinking about having them come clean our new house once we get settled!"

Window Cleaning FAQs, answered by experts

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.

Regular cleaning, non-abrasive cleaners, and scheduling professional services every few months help maintain clarity and shine.

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.

Yes, many professionals use biodegradable detergents and water-efficient cleaning techniques to minimize environmental impact.

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.
