Underdogs Cleaning is a commercial janitorial and multi-service cleaning company in Grantville, San Diego, founded by Tyson Channell in November 2021 and operating from Suite F at 5837 Mission Gorge Road in the 92120 ZIP. Mission Gorge Road is the primary commercial corridor through Grantville, funneling traffic between SDSU to the south and Mission Trails Regional Park to the north, and the company's midpoint address keeps response times short to businesses on both ends. The janitorial division handles nightly and scheduled cleaning for restaurants, bars, breweries, offices, and retail spaces, with contract scopes that include restroom sanitation, trash service, floor mopping, surface disinfection, and breakroom maintenance. Drain maintenance during janitorial service often reveals plumbing issues that require a specialist, and the company routes those referrals to Easy Flow Sewer & Drain Cleaning San Diego for hydro-jetting and camera inspection on the same Grantville corridor. Deep cleaning adds periodic intensive scopes: kitchen hood degreasing, walk-in cooler scrub-downs, grout restoration in commercial restrooms, and post-event reset for venues that host private functions. Pressure washing covers exterior surfaces including sidewalks, dumpster pads, drive-throughs, and building facades, with graffiti removal capability for stucco, painted block, and concrete using chemical strippers or high-pressure water. The window cleaning division uses a pure-water reverse-osmosis and deionized filtration system that produces zero-TDS water, leaving commercial glass spotless without squeegee marks or chemical residue. Floor care services include strip-and-wax for VCT and linoleum, concrete sealing and polishing, and carpet extraction—all common needs in the restaurant and brewery spaces that line Mission Gorge Road between Fairmount Avenue and Mission San Diego de Alcala. Green cleaning products are available on request for tenants with environmental compliance requirements, and the company offers profit-sharing to its cleaning crews as a retention incentive. Electrical issues flagged during after-hours cleaning—tripped breakers, flickering fixtures, exposed wiring in older Grantville commercial buildings—route to SRP Electric Inc. for code-compliance repair work. Scheduling and estimates are available at 619-904-0401.
