"Polite enough, but not very responsive with follow-up texts and scheduling. Inconsiderate of damages done to the home while completing his tasks (unnecessary demo in the basement, severe scuffing of hardwood floors during radiator repairs, etc). Left old pipes and trash from a job for the homeowner to dispose of. Installed new garbage disposal WITHOUT power cord; small appliance is not able to be used and drain now clogged."

"Curtis diagnosed the problem and fixed and verified the furnace is working correctly. He did this in just a little more than 30 minutes. His 18 years of experience was well worth it. He took apart the gas valve area and found between the gas valve and the orifice to the burner had a spider web obstructing the gas flow. The furnace works well now. Curtis was very professional and honest. Thank you, Curtis, for a great job. I had another company check the furnace last week, but the tech they sent did not have the experience to correctly diagnose the problem."

"Terrible experience. I had hired Mike multiple times previously and had great outcomes. Then, I wanted to replace plumbing in half of my home. He send his employee, who was a total nightmare! Screaming profanities in my home, never working, my husband ended up asking Shawn to leave. One of Bathrooms needed to be redone, because Shawn did all the work incorrectly. Mike had the nerve to tell me "he was losing money this job." Well, Mike never checked the other areas Shawn had finished. I had to redo my kitchen plumbing 5 years and ago. I also have had to replace my shower tile due to the incompetence of this company. No apologies, or accountability for the disaster. Only gaslightling, pretending to be a victim, and blaming his employee. Hire at your own risk!"

FAQs for plumbing installation for a remodel or addition projects in Louisville, CO

Adding bathroom plumbing to a detached garage starts with the basic line installation cost of $900 to $1,300. On top of this base expense, you'll need to budget for each fixture. A toilet costs  $250 to $550, sinks cost $150 to $800, and a shower or bathtub costs $400 to $1,900. The project will also require ventilation, moisture-resistant materials, and possibly electrical work. Remember that these costs reflect only the plumbing aspects—additional construction, finishing, and permitting expenses will apply to complete a functional bathroom space.

While certain aspects of garage renovation might be suitable for DIY enthusiasts, plumbing installation requires professional expertise. Connecting to water and sewer systems demands specialized knowledge and equipment, and improper installation can result in severe water damage, code violations, and potential health hazards. Most municipalities require permits for plumbing modifications, and these often stipulate that licensed professionals must perform work. Consider limiting your involvement to simpler tasks like painting or basic finishing work.

The timeframe for adding plumbing to a detached garage spans one to three days for the actual plumbing work. However, this represents only the active installation period. The complete project timeline must account for planning, obtaining permits (which can take weeks depending on your locality), coordinating multiple contractors if needed, and addressing any unexpected challenges that arise during installation. Weather conditions can also impact excavation and outdoor connection work.

Adding plumbing to a detached garage will likely increase your property taxes. Tax assessors consider plumbing an improvement that enhances property value and functionality. The specific tax impact varies by location and project scope. Converting a garage into living space with plumbing facilities can trigger significant reassessment in many jurisdictions. Before proceeding with your project, consult your local tax assessor's office to understand the potential tax implications and factor this ongoing expense into your decision-making process.
