Perched atop Howell Mountain above the valley fog, Angwin offers peaceful woodland living, prestigious high-elevation vineyards, and quiet residential neighborhoods. Mountain properties in Angwin encounter pine pollen, red volcanic dust, and higher forest humidity, which quickly settle on exterior glass and indoor living surfaces. At Bertha's Cleaning and Janitorial, Bertha Vargas and our seasoned family team bring twenty years of dedicated cleaning care to Angwin homeowners, providing deep sanitizing, floor scrubbing, and meticulous housekeeping that keep mountain residences pristine.

In Angwin, our housekeeping team delivers comprehensive care tailored to mountain homes and country estates. We excel in hand-washing dusty baseboards, wiping window sills, scrubbing kitchen backsplashes, and polishing hardwood floors exposed to outdoor foot traffic. For local faculty, retirees, and vineyard managers, we provide customized recurring maid visits, thorough seasonal deep cleans, and rental turnover care. We use gentle, pet-safe, and biodegradable cleaning products that preserve your home's air quality without overpowering mountain freshness.


Angwin homeowners choose Bertha's Cleaning and Janitorial because we share the community's bedrock values of honest work, family integrity, and dependable craftsmanship. Operating since 2003, our company is fully insured with general liability coverage, protecting your property completely. Bertha Vargas personally ensures that every cleaning job receives attentive, thorough care from start to finish.
