Frequently Asked Questions


What service does Werts Window Cleaning offer?

At Werts Window Cleaning we feel it is important to do one thing, and do one thing well. Unlike some window cleaning companies, where window cleaning is an afterthought, we only clean windows. Our services specialize in commercial and residential windows that are 3 stories or less. At times we can do windows that are higher, so feel free to request an estimate.

How often should I have my windows cleaned?

The schedule you choose is really up to you. Most commercial customers choose at a minimum to have their windows cleaned once per month. However, high traffic businesses such as restaurants, should have their windows cleaned more often.

Residential customers usually choose to have their windows done twice a year, in the spring and autumn. However, some who enjoy clean windows choose a regular maintenance schedule of once a month. Whatever you choose for your home or business, Werts Window Cleaning can accommodate your specific needs.

How much does it cost?

Probably less than you think. In fact many customers are pleasantly surprised at the affordability of having their windows professionally cleaned. There are many factors that go into pricing a window cleaning job. These include: the type of windows, how high the windows are, and how often they will be done. At Werts Window Cleaning we give each estimate the individual attention it deserves to ensure the highest accuracy. We will never give you a low price to get your business and then raise the price shortly thereafter.

Why should I have my windows cleaned professionally?

We understand that in today’s economy choosing where to spend your money is important. Having your windows cleaned professionally actually makes good economic sense. Here are just a few of the reasons why:

  • Keeps employees on more important tasks

  • The time it takes for a professional to clean your windows is far less than it would take an employee

  • The job looks better and actually attracts customers

  • Regular maintenance always saves in the long run


Will my windows get dirty if it rains after you clean them?

No, rain doesn’t make windows dirty. Dirt, insects, pollen, and other pollutants do. If these are present on the glass when it rains, the rain simply attaches itself to the dirt and often makes the windows look even worse. However if the windows had been clean, then the rain would simply sheet off the clean glass and they would continue to remain clean. In fact, windows tend to get dirtier in the winter time, since unlike rain, snow sticks to the window and leaves the dirty residue behind when it melts. That is why a year round maintenance schedule is important.
