"I hired Chyrel from Bright Clean Windows to clean all of the windows in my house. Not only did the windows come out great, but she also went a above and beyond and she cleaned my gutters that were clogged with debris. I would hire this company again in a heart beat!"

"Recommend Joslin & Co for window cleaning. Hands down the best not just for service but the great customer service as well. You can tell Nico takes great pride in his work with the care for the building and his customers! He is a really cool down to earth guy yet still professional and quick and efficient in his services! 10/10 in my book."

"They were excellent at showing me what would be the best lighting solution for my home. The installers were professional and cleaned up the work area. My neighbors have complimented me on how beautiful my house is since the lights were installed. I couldn't be happier."

Window Cleaning FAQs, answered by experts

Well water can leave ugly marks on your window. A vinegar-water spray will remove most well water stains from your windows. However, you can also use a baking soda paste if the stain is too stubborn. Consider applying waterproofing protection to the glass surface after cleaning for long-term protection. A protective film or spray layer also makes it easier to remove the water stains next time.

No, but removing window screens will achieve a deeper clean. If you aren’t sure how to remove your screens, you can still clean them while in your window. You can follow the same cleaning steps, but you may not be able to get into corners or struggle to clean the entire screen if the window is up high.

Professional cleaning offers deeper sanitization, reaches grout inaccessible by home tools, and restores tiles without causing damage. Technicians have expertise and equipment that ensures long-lasting cleanliness and improved aesthetics.

While clean windows don't automatically increase home value, they make your home look more attractive from the outside, and since the exterior is the first thing a potential buyer will see, it can help make a good first impression that paints the rest of your home in a positive light. Educated homebuyers will see that your home is well cared for if they see clean window tracks and sparkling window glass, which can contribute to an overall positive opinion of your property. Clean windows give the impression that the rest of the home—including systems and appliances—is probably well-kept, too.

Costs depend on fabric type, drape size, cleaning method, and whether additional services like pressing or deodorizing are included.
