"Let me start off with how amazing these guys are! They have worked with me every step of the way with payments and are very patient with my lack of being able to pay because of certain circumstances that happened. I make payments when I can and they are very flexible with everything! And my house was so clean when we came back i was pleasantly surprised! Thank you again for your hard work!"

Window Cleaning questions, answered by experts

One of the best professional cleaning solutions that won’t leave streaks is one gallon of distilled or bottled water mixed with 2 to 4 teaspoons of dish soap. Apply using a sponge in a figure-eight motion, and then use a squeegee to remove the majority of the water and soap. You can finish drying with a piece of old black-and-white newspaper to remove any residue for a streak-free clean every time.

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

Yes, you can use glass cleaner on outside windows, but only after you’ve rinsed away as much debris as possible. Using glass cleaner on top of a layer of dirt will only make it harder to clean. 

The easiest way to remove window decals is to soak the area in hot, soapy water. Let it sit for 15 minutes before scraping it with a plastic scraper or the edge of a credit card. You can also remove window decals with white vinegar, rubbing alcohol, or applying heat from a hairdryer or steam cleaner.

Clean regularly and inspect seals for wear. Replace damaged parts promptly to maintain effectiveness.
