Demakas Plumbing & Heating, Inc.

Demakas Plumbing & Heating, Inc. operates as a plumber in San Francisco, California, maintaining 24/7 availability across all seven days. The company holds a 3.4-star rating derived from 10 customer reviews, providing plumbing services throughout the San Francisco area. No specific founding year or license information is available from the business data.

The company does not maintain a website, and no online business information was accessible at the time of this review. This limits the ability to verify specific service offerings, brand partnerships, or specialized certifications that might distinguish them from other plumbing contractors in the San Francisco market.

Two detailed negative reviews raise significant concerns about this contractor's business practices. Richard Barnes reported that technicians failed to verify heating functionality across all three floors of his home following a December 2023 boiler repair, then demanded an additional $200 for a return visit to correct their incomplete work. A separate reviewer documented a complex billing dispute involving unexpected charges for two plumbers instead of one, overtime surcharges not disclosed upfront, and hour-rounding practices that resulted in a $1,200 credit card charge. The same reviewer noted that payment was processed without providing an invoice or opportunity to authorize the final amount.
