"Excellent from start to finish. Quick turn around time from when the contact was made to arrange for the work and when to job was finished. Rudy, arrived on time and texted me that he was on his way. He is very professional. He knows windows. I cant believe how good my windows look, including removing some silicone . I can only say the truth, he is great. I already have my neighbors taking his card to schedule an appointment. Thank you Rudy."

"The 2 workers went above and beyond. Made a badly stained and mildewed awning look brand new. Keith also fixed 2 door screens that had been pushed out by my grandchildren and my dog by accident. I did not ask he just did it. And Mary came back in the house to look into a smudge in a window that I look out of all the time. No attitude, just happy to take care of it. Very pleasant to have around. Had no qualms over having them in my house. Ron, you have a great crew."

Window Cleaning FAQs, answered by experts

Hard water stains are caused by hard water. Hard water contains a lot of minerals, like calcium and magnesium. When water on your glass surfaces dries out, the minerals stay behind and stick to the glass. This results in a residue that looks like white cloudy or streaky spots. Call a pro to install a water softener to banish hard water problems.

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.

To maintain a glass shower door, clean it regularly with a non-abrasive cleaner to prevent soap scum and hard water stains. Using a squeegee after each use is also recommended. Additionally, periodically check for leaks and ensure all hardware remains secure to prevent long-term damage.

Getting a streak-free shine after cleaning your windows requires both the right cleaning solutions—which can either include warm water and dish soap or warm water and rubbing alcohol—and the right tools—namely, a squeegee and a microfiber cloth. To make your streak-free glass cleaner, combine one gallon of warm water with a few drops of dish soap, and mix. Apply with a sprayer or sponge, and then dry with a squeegee, microfiber cloth, or old black-and-white newspaper pages.

Pros offer comprehensive cleaning that addresses areas you might overlook, ensuring an immaculate home.
