"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

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.

Professional cleaning utilizes industrial-grade equipment and formulated cleansers that penetrate deeper into fabrics, removing stubborn dirt without risking damage that DIY approaches might, such as surface abrasion from improper tools.

Long-handled telescopic brushes are the best way to clean the outside of a house without a pressure washer. There are even special attachments for cleaning the outside of windows. Use a gentle cleaning solution for both the roof and siding to avoid harming the finishes. Be sure to rinse the area thoroughly with a garden hose after scrubbing.

Professionals remove dust, allergens, and stains while preserving fabric integrity and enhancing the appearance of window treatments.

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