About Stewart Mechanical Inc
Stewart Mechanical Inc operates as a mechanical contractor serving Battle Ground, Washington, and the broader Pacific Northwest region. The business holds a 4.7-star rating derived from 13 customer reviews, indicating generally positive client experiences. Their service portfolio encompasses industrial piping, hydronic systems, HVAC installations, and commercial plumbing. Operating hours are Monday through Friday from 8 AM to 4 PM, with Saturday and Sunday reserved for emergency callbacks. The company maintains a web presence at stewartci.com and can be reached directly at (360) 892-5215 for project inquiries.
What distinguishes Stewart Mechanical is their specialized capability with complex commercial systems that other contractors decline. Their website explicitly mentions handling challenging industrial piping for restaurant, medical, and facility applications, including gas, oil, air, and process piping installations. The hydronics division installs complete heating and cooling systems featuring boilers, chillers, and cooling towers. Their team has earned recognition for strong corporate values and technical expertise on sophisticated commercial HVAC projects, positioning them as a resource for complex tenant improvements and new construction mechanical systems.
Customer reviews document specific scenarios demonstrating their response capability. A reviewer described Brandon R. arriving within 20 minutes to address a severe central trunk line clog affecting 10 of 12 operatories in a medical facility, working through what the reviewer called a challenging job that tested their Patterson Service Tech team. Another reviewer mentioned working with Stewart Mechanical throughout the past year and experiencing pleasant, professional interactions with their team. However, one negative review from Steven Kerry cited missed deadlines, inconsistent communication about contract status, and work the reviewer characterized as sloppy.
What Customers Say
Three of five reviewers specifically named team members, with Brandon R. earning particular praise for rapid same-day response to an urgent commercial plumbing emergency. Positive reviews highlight professionalism and technical skill, while the lone negative review cites communication issues and missed deadlines rather than pricing or technical competence.
