"This company company was SO amazing to work with. When I first asked for a quote to clean my patio, a representative of the company, named Carmen, had me send pictures of the space and gave me a formal quote. Carmen was always attentive to every question I had about the process to clean my patio and always gave me a straight answer. Wandel, the cleaner, was on time for the job and power washed the fence, windows, cement patio and did yard/waste removal. Handel even came back for a second day to continue to thoroughly clean that patio upon request. The patio space looks beautiful now. I highly recommend using Square Services!"

Window Cleaning FAQs, answered by experts

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

Professionals use pH-balanced solutions, fabric protectors, and safe steam cleaning technology for specific fabrics. These products are designed to break down dirt effectively without leaving residues.

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.

Cleaning services typically offer a range of options. Some of the most common cleaning tasks include:

  • Windows: $4–$10 per window

  • Refrigerator cleaning: $10–$40

  • Carpet cleaning: $75–$200

  • Baseboard cleaning: $25–$75

  • Laundry: $5–$20 per load

  • Cabinets: $20–$50

  • Polishing or waxing floors: $25–$50

  • Dusting: $10–$30

  • Oven cleaning: $20–$40

There are a few qualifying questions you can ask a professional window cleaner to help you decide if it’s the right company for you:

  • Does your price include the inside and outside of the windows?

  • Will you clean the tracks, rails, and other internal components?

  • Are you fully insured?

  • How many years of experience do you have?

  • What kind of cleaning products do you use?

  • Do you have any customer references?

  • Do you provide any other services, like exterior power washing?
