McKowski’s Maintenance Systems, Inc has been providing quality janitorial & professional cleaning services for commercial, industrial, multi-tenant office buildings and Homeowner associations since June 1979. Our success is based on the fact that we value our relationships and continually strive to improve and enhance the janitorial services we deliver in San Diego. We have never taken for granted that we are a service company and consider it a privilege to be given the opportunity to do just that, provide quality janitorial services for your business. To that end we still service many of the accounts that were the foundation for our success and value the long-term relationships we have established. We are always looking to enlarge our customer base and look forward to the opportunity to meet and discuss how McKowski’s can be of service to you.
