But even local property owners and property managers would prefer dealing with a one-stop contractor who can solve all or at least many of their pavement needs. So contractors have figured out a variety of ways to meet that demand. Many have diversified, adding support services to their main pavement maintenance service. The low cost of adding sealcoating, striping, cracksealing, and even pavement repair to a business makes expansion a relatively risk-free proposition.
Another approach is to affiliate with other contractors who provide services you don't. Each can essentially market the services of the other contractor, becoming the one-stop shop for the customer, without taking on any additional risk. This subcontracting approach has been going on for years and seems to have accelerated, at least informally, in recent years.
