How Water Quality can Affect Window Cleaning
Water quality has different benefits, depending on its use. Hard water is beneficial for drinking but detrimental for cleaning. Several methods are available to change the quality of water for optimal cleaning purposes. First, learn how water quality affects the final outcome of window cleaning.
The Meaning of Water Quality
Water is polluted mainly by the natural environment, industrial machinery or sewer systems. The quality of water is determined by its chemical, biological and physical composition. The common pollutants found in untreated water are bacteria, viruses, salts and pesticides.
The indicators used to test water quality include pH, color, odor, taste and alkalinity. Testers also check for the presence of bacteria, metals and organic matter. Different government agencies limit the level of contamination in drinking water; however, certain amounts of contaminants are still allowed in tap water.
The Significance of Hard Water
Dissolved minerals increase the hardness of water and reduce its effectiveness in cleaning. Magnesium and calcium are two minerals that reduce the foaming and cleaning effects of soap. Hard deposits form on certain surfaces like the interiors of boilers or the rims of bathtubs.
The Problem With Total Dissolved Solids
Total dissolved solids (TDS) are organic and inorganic materials that exist in water. High levels of TDS cause spots and streaks to appear on glass. These levels are measured at 20 parts per million (ppm) or higher. For streak-free windows, the water quality level should be below 20 ppm.
Quality Tests and Cleaning Methods
Professionals use certain at-home tests like titration kits to evaluate water hardness. Many use reverse osmosis as one method of cleaning and purifying water. The water is poured through a semipermeable membrane and the dissolved solids are extracted.
How Window Cleaning Becomes Effective
Softening the water involves removing these minerals, which increases the effectiveness of cleaning. Compared to using hard water, soft water requires less soap to create the same thorough window cleaning. There are also no spots or streaks that appear on the surface. The lifespan of the window is increased when deposits do not build up.
What to Look for When Hiring a Window Cleaner
It may sound strange, but a lot of customers come to us with horror stories from previous “professional window cleaning services”. Recognizing a quality window cleaning service seems simple, but isn’t as easy as you might think. This article illuminates a few key things to look for and what to avoid when hiring a professional window cleaner.
Experience and Customer reviews
A quality window cleaning crew is only as good as their last review(s). When seeking a window cleaning company, google reviews is your best friend. Customers should always opt for a company that has a better than average rating. Four stars and up (five if you can) is the rule of thumb we recommend.
Additionally, Google, Facebook and services like Thumbtrack are great resources to give personal insight into specific jobs. This is a perfect opportunity to scope out whether a particular window cleaning company has ever worked on a building similar to yours.
Quantity matters as well. When looking for professional window cleaning services find one with high ratings and tons of reviews. Anyone can have a rating of “5” with five reviews, but do they have a “5” with seventy-five reviews?
License and Accreditation
Like any business, window washing companies must be approved and licensed by the state. Sounds like a no-brainer, but this is something that slips through cracks all the time. Customers come to us almost daily complaining about the work “some guy” did for them under the table. The offer is always so enticing, competitively priced and “simple”, but almost always seems to end up in the weeds…or worse. Beyond the usual shoddy lack of quality, it’s super risky to hire someone under the table for window washing. Legitimate businesses are required to insure their services to protect themselves and you. Save yourself the trouble and risk and stay away from unlicensed and uninsured window washing “one-man-bands”.
Price is one of those things that totally is and is not a metric for quality. Of course, everyone is trying to get the best bang for their window washing buck, but in lots of cases ultra-low pricing can indicate poor services. Like most services, good window washing usually finds its way to a healthy, competitive middle ground. Simply put, you don’t want the bottom of the barrel, but there is no reason to overpay either.
Safety should be one of the first priorities when choosing a window cleaning company. Always opt for companies that have an excellent safety reputation. Again, Google reviews are your best friend. Do a little research and make sure that you’re hiring a window cleaning company that has a high historical standard when it comes to safety.
This is a critical factor for any credible organization. Quality window cleaning companies will run background checks to assess whether their employees are legitimate or have been involved in criminal activities. This is crucial since they work with your interiors and exteriors.
Guarantees are really really handy when it comes to any sort of washing service. Beyond the usual “100% Satisfaction Guaranteed” type stuff, look for companies that protect your cleaning investment. Similar to car washing services, look for window washing companies that provide some sort of restitution or reclean if it rains within 30 days. You will be happy you did.
