"I want to thank Hosack Plumbing, and Kent, for getting my situation cleaned up quickly and professionally. My water heater install is perfect, my water pressure spot on thanks to the new PRV, and is ready for inspection. Kent was thorough, professional, and very clean. He noticed my mask when I answered the door and wore a kn95 mask the whole time. The life coaching advice was an added bonus. Kent's work was great and I'm very pleased with the service provided."

"This is the second time I have hired Metro Lawn Sprinklers & Landscapes. The first time they installed an effective French drain system at a prior residence. At my newest residence they recently extended / relocated a downspout drainage popup emitter to be further out in my yard away from my house. The day of the work they arrived on time, reviewed the work to be done and completed the work within the time estimated and cleaned up the work area. I am very pleased with the work they did. If I need any more landscaping / drainage work, Metro will be the first company I call. I trust their integrity and their competence."

"Easy to work with, courteous and cleaned up after the job was complete. Completed almost a year ago and no more water leaks and no farther inward movement of our walls. Quality work and no further problems at that end of the basement. Having water seepage at the other end and will plan to hire again to address our new problem. Best price of the four estimated I received."
