"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."

We pride our company on reliability, great communication, integrity, and quality work. We are experts in our trade and will do our best to keep you as educated as we can on your particular task or project. We look forward to earning your business!!!!!

"Our hot water heater went out recently. It was 12 years old, so we knew we needed a new one. It took quite a bit of research to find a reputable company that didn’t have exorbitant prices. Other businesses told us things like: we needed all new pipes. (We didn’t.) A new hot water heater would be $3,000 to $5,000 plus labor on the of that. ( way overpriced), etc. Finally, we found an excellent smaller local company. We went with Pure Water Services in Loveland. They’re honest, reasonably priced, and absolute pros. They were able to get us scheduled for a new hot water heater within days . Their master plumber Patrick was courteous, extremely knowledgeable, and very thorough. Patrick is an impressive and experienced plumber. Alexander keeps in touch daily with every step of your project repair. I was impressed with how kind, and professional he is to customers. We are so thankful to have hot water again. They stand by their work. My husband and I highly recommend them!"

"Router Guy is great! I used them previously for a large job with a leaking pipe through the wall, where they had to go into the wall to fix it. This time, I had clogged plumbing. They were very responsive. Eric showed up timely. He was very professional and friendly. The fixed the clog no problem (the plumber I had the day before said they couldn't unclog it and it would be 20 grand to fix!) He was great, and rooter guy seems to be consistently good. I only bothered getting another plumber because I couldn't remember who did my last work - that taught me a lesson! Rooter guy is now saved in my phone :) thanks for your help, your professionalism, kindness, and honesty. "

FAQs for plumbing installation for a remodel or addition projects in Boulder, 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.
