Local Martinez experience
Martinez is an incorporated Contra Costa County city on the Carquinez Strait and serves as the county seat. The community includes a historic downtown, older residential neighborhoods and later development extending into surrounding areas. The City operates its own water treatment system and administers local building permits.
Our team handles plumbing, drain, sewer, water-heater, heating and cooling problems throughout the Martinez area.
Living in Martinez
Housing & development
Martinez includes historic properties, established neighborhoods and later residential development. Differences in home age and location mean plumbing, drainage, sewer and HVAC systems can vary considerably from one property to another. The City's Building Division administers permits and inspections within city limits.
Climate & seasons
Martinez sits between the Carquinez Strait and warmer inland Contra Costa County. Marine influence can moderate temperatures compared with communities farther inland, while summer heat still creates residential cooling demand and winter weather increases heating use.

My water heater died late last night. Matt Hartman was able to respond very quickly. He was thorough, professional, explained everything before starting and made sure I understood the process.

Matt was very communicative and kept us informed as to what he needed to do. In Demand was reasonable in their pricing...they dug a new trench & laid new PVC from the water meter to the house.

I call In Demand whenever I have plumbing issues or needs. Every technician who has done work and installations for me is professional, knowledgeable, courteous and friendly. I especially appreciate that they wear booties, that they respect my home then clean up and leave my home as neat and tidy as it was when they started working. Thank you to Elijah for finding and ordering the bathroom sink faucet I wanted then coming back to replace my old one when it arrived. Their 24 hour service number is terrific so you can call anytime and talk to a real, live person to make an appointment. Ben did an excellent job scheduling my appointments and communicating with me once my faucet had been delivered then Elijah came to install it the following day. I don't like when plumbing problems arise, but I like and appreciate knowing I can count on In Demand in Antioch when needed!
