Cody was professional, knowledgeable, and as dedicated to getting the job done right as if it had been his own home.

"????? If I could give zero stars, I would Hiring this contractor was a nightmare from start to finish. The bathroom they delivered is so poorly done that I feel like I need to redo it entirely. They rely on subpar subcontractors with no professionalism or craftsmanship. ? Overpromise and underdeliver: I had to stay on top of every detail myself, doing the job the contractor was hired to manage. ? Unreliable: Never kept appointments or confirmed schedules. The only time they showed up on time was to collect payment. ? Unsafe practices: At one point, a subcontractor was cutting concrete inside the bathroom with a gas?powered tool, filling my entire home with smoke. I had to intervene to stop it and argue just to get basic protections like tarps in place. ? Poor management: Subcontractors openly complained about not being paid, and I even had to send one home myself because of unacceptable behavior. ? End result: Substandard work that does not reflect the money spent. Save yourself "

"Fixed two shower problems. One was linking and the other didn’t have enough hot water pressure. Jason was able to get a 29 year old shower stem unit replaced saving me hundreds of dollars on one bathroom. The second bathroom needed a water pressure adjustment again saving me hundreds of dollars."

"Huge shout out to the crew at Main Stream Mechanical. Eric came out, reviewed my current system, and gave me his recommendation for replacing my furnace and hot water heater with a new, energy efficient furnace/hot water heater. Brenda, as always, was a pleasure to deal with. Answered all my emails and calls promptly and gave me all the information I needed in a timely manner. She even went out of her way to register my new furnace and provide me with all the information I needed to apply for my rebate! Nick and Marcus did a great job installing my new furnace/hot water heater. Both were very friendly and professional. Nick answered all my questions, gave me a “tutorial” on the emergency shut off procedure for my new furnace, and did a fantastic job re-plumbing all the lines needed for the install. I highly recommend Main Stream Mechanical for all your HVAC needs."
