"Initially I requested an estimate for a plumbing project already in progress with some challenges. Keith responded immediately to get details and schedule to come out to look at what was needed. He proposed a solution that eliminated any impact to walls or tile to replace old valves and faucets. He and his team completed the work on time and were neat and professional and results were better than I expected. There was no damage at all to what was old tile. I subsequently had him assess an old water heater and decided to replace it. It had to go into a very small areas and be upgraded to code and he was able to solution the replacement to fit perfectly in the limited space. Previously on the project we had noticed a periodic odor of gas but no one had verified a source. Keith identified a leak in the area of the furnace right next to the water heater. We had decided to upgrade the furnace and AC and again Keith and his team were able to get an order in quickly, get the install done exactly as committed and fixed the gas leak in the process. Based on the quality of work performed in each case and the expertise of the team I hired Plumbing Tree again to assess an old furnace and AC at my primary residence. The furnace had been failing at the end of the winter but I waited for summer to replace and it had deteriorated and was not safe. Keith evaluated and gave me two options and was able to get the order in immediately after I decided to go ahead. He scheduled the install within a few days. His crew was on time and completed the install of furnace and AC in one day. Again they were neat, efficient, described all the changes from the old furnace and thermostat to the new and answered all my questions. Everything has been functioning just as I expected for both heat and AC. I recommend Plumbing Tree for these services based on quality and reliability - also cost was competitive and the team they used had the expertise required. Additionally they were easy to work with and I plan to use them again on another project. Thanks Keith and team- I appreciate the quality work!"

"Everything was fine. Our sewer clean out line was not installed correctly, which meant that the plumber had to take off our toilet to access and scope the sewer, but he was friendly, courteous, and as quick as was possible, all things considered."

"I recently hired Pure Water Services for a series of plumbing issues in our home that we purchased as a short sale and in dire need of repair. I couldn't be more satisfied with the service I received. From start to finish, the experience was timely and top-notch! First, they installed a new sink and disposal in our kitchen. The process was seamless, and the plumber was punctual, professional, and highly knowledgeable. He walked me through the installation, ensuring everything was done to my satisfaction. Next, we had a pesky shower leak that was causing damage to the ceiling below. Patrick quickly diagnosed the issue and made the necessary repairs. I appreciated his attention to detail and the effort to minimize disruption to our home. The leak was completely resolved, and weâ re relieved that further damage was prevented. Finally, we needed the pressure regulator on our sprinkler system replaced after the prior owner failed to winterize the system. Again, Patrick was efficient and thorough and ensured the value and system was functioning properly before leaving. Overall, the professionalism, expertise, and customer service provided by Pure Water Services were outstanding. I highly recommend them for any plumbing needs you may have. I will definitely be calling them again for future projects!"

"Received quotes from three established and recommended plumbing and heating companies. All bids were over $2,200 to install a 40 gallon hot water heater one can buy retail for under $1,000. Found James highly recommended on the internet and BBB and hired him to do the job. James showed up same day. He was very thorough in his work and did a great job. I thought his bid was both a reasonable and fair price."

"Kyle replaced shut off valves for the main water line that had seized up. He also installed new plumbing, kitchen sink and faucet. The old plumbing had several connections and caused issues with dishwasher and drain. Kyle explained everything, is efficient and the price was reasonable and the work looks great (I have more room under my sink). He is now my go to for all plumbing issues and will be doing the plumbing in my bathroom remodel."

"We thought our 13-year-old water heater was leaking and needed to be replaced. Our house is almost 100 years old, so we have called At Your Service Plumbing several times for snaking slow drains and the like, always with quick and affordable results. This time, Eduardo came out and said that the water heater was fine, and the leak was coming from a poorly-installed and now broken coupler between two hoses. (This was done by a different plumbing company years back.) He swapped out the coupler pretty quickly, saving us the cost and labor of replacing the whole thing. These people are competent, honest and nice. After living in Denver for almost 25 years, we finally have a company we can count on for plumbing issues."

"Patrick from Purewater Plumbing was a pleasure to work with. Even though "we" not Purewater" ordered the wrong item, causing an installation issue, Patrick reordered and took care of the issue. Installation, quality of work, and attention to detail are amazing. The first time we have called Purewater and we now have Purewater to call for all our plumbing needs Thanks, Patrick and Clearwater Mike and Ofelia Russell"

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