"Chris did a great job removing black and green mold from the concrete around my porch. He also did a great job cleaning the siding around my porch and patio. And I was amazed with how he cleaned the white trim on my enclosed patio; I thought I was going to have to have it repainted but it looks almost new after the cleaning. I would have given a 5 star rating except that Chris missed the initial estimating appointment and left a small lake of water on my enclosed patio. In the future, maybe Chris should have a ShopVac with him to clean up excess water. I would highly recommend Chris and hire him again."

Window Cleaning FAQs, answered by experts

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

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.

Do not mix bleach with vinegar, ammonia, acidic liquids, or other cleaners or detergents as toxic fumes result from the chemical reaction. Mix bleach only with water to avoid dangerous chemical reactions. Even mixed with water to dilute it, bleach can still be harmful to your skin, eyes, and lungs.

A handy hair dryer will quickly remove condensation from your window, but it’s only a temporary fix. The hair dryer maneuver will not repair the root of the window fogging problem, which is likely a broken window seal. If you need to defog the window quickly, such as if guests are coming over, use the hair dryer. However, for a permanent solution, defogging the window or replacing it are the only options.

Smoke stains, grease buildup, mold, and water spots are common reasons for hiring professional cleaning services.
