According a 2017 IBIS World report, the U.S. building exterior cleaning market (i.e. the building facade cleaning market) is worth $9 billion, and has an annual growth rate of 5.0%. IBIS World states that there are a total of 115,987 businesses operating within this market.

We calculated that the average revenue for businesses in this market is about $77,600 (or $9 billion divided by 115,987 business). We believe that this insight suggests that the building facade cleaning market in the U.S. is highly fragmented, and composed mostly of smaller sized businesses. This idea is further supported by the IBIS World report, which states that "there are no companies with a dominant market share in this industry."

This heavily fragmented business landscape posed a challenge in attempting determine a list of top companies, because small-sized and privately owned businesses rarely publish their annual reports or other financial information which would provide insight into their business operations (such as their client numbers), revenue information, and other information which typically helps to provide insight that can be used to determine which companies are top and for comparing them.

Therefore, we developed a different research path which would help us locate and determine which companies were top. First, we looked for any existing nationwide companies operating in this space, and analyzed company databases and company websites to locate data pertaining to your 'top' criteria. Once this research method was exhausted, we also located a pre-compiled list of the largest cities in the U.S., based on our assumption that these cities have the highest number of commercial buildings, and therefore, we further assume that these cities would be the largest markets for building facade cleaning in the office and commercial segment.

Next, we conducted research to locate qualitative data that would help us to narrow down which companies in each of these cities are considered the leader in that market. Specifically, we looked for companies whose websites claimed they were a leader, or the number one leader in those individual cities; or we looked for companies that had been awarded as 'top' or the 'best' in those regions; or we analyzed consumer reviews and top ten lists which provide a ranking of the best companies in those individual cities. We then analyzed business intelligence databases such as Owler and Hoovers to locate revenue information for these companies, as these types of business databases often provide revenue estimates for smaller-sized and privately held businesses. We used these revenues compare the businesses we located to determine which one had the highest revenue for each of these cities.

We also analyzed company websites in attempt to locate any additional insights which reveal their number of clients, number of class A buildings serviced, or amount of square footage covered per year. The vast majority of companies we located did not make this information known, therefore, we choose to focus on making revenue comparisons in order to determine the top companies, as this is the information which was most publicly available across the board. Exceptions were made for companies for which revenue information wasn't available, but where we were able to locate data which demonstrated the companies very large size.

Below, you will find an overview of our findings.

top ten largest cities in the u.s.

These are the largest cities in the U.S., based on highest population. After we exhausted our search for companies that are operating nationwide, we focused on searching for the leading companies focused on these markets, as we assume these cities are the largest markets for this industry, based on their high numbers of commercial buildings.

1. New York City
2. Lost Angeles
3. Chicago
