"I purchased a large pedestal sink when Covid hit and discovered the plumbing needed work before I could install it. I called Henco plumbing and Joe came out and explained what they would need to do to install my new Pedestal sink, he answered my questions and concerns and gave me a quote for the job. Adrian came out today and reworked the 1935 plumbing and installed the new sink. He did an awesome job. The plumbing work is perfect and hidden behind the pedestal. The caulking work was excellent. I am very pleased and impressed with Henco Plumbing. I would use them again."

"The whole experience with 3 Mountains Plumbing was outstanding from Nicole at the office to Jon Marc and Peter, the plumbers. They originally scheduled me for an appointment 5 days out, but Nicole watched appointments carefully and moved my appointment to the same day I called. Jon Marc, the plumber, was very knowledgeable and professional. He gave me different options, which allowed me to decide what worked best for me. He even gave me a teacher discount. After installing my water heater at 8:00 p.m. at night, he discovered a manufacturing problem with the water heater. He called another plumber, Peter. Peter was going off shift and was at the office, but got another water heater and brought it to my house so Jon Marc could install it! I think other plumbers would have said that they needed to come back the next day, but Jon Marc stayed until 10:00 p.m. installing the water heater. I will never use another plumbing company because 3 Mountains is the best! Nicole, Peter and Jon Marc... Thank you!"

"As a Realtor, having reliable contractors I can confidently recommend to my clients is incredibly important, and Eric with Tight Lines Plumbing is always my first call. He recently installed a new water heater at my home in Wilsonville, and the experience only reinforced why I trust him so much. Eric is honest, knowledgeable, responsive, and does exceptional work. He takes the time to explain everything, offers fair pricing, and truly cares about his customers. My clients have always had great experiences with him, and I never hesitate to send his name their way. If you’re looking for a plumber you can trust, whether it’s a water heater, repairs, or a larger plumbing project, I highly recommend Tight Lines Plumbing!"

"Let me tell you that Bluefrog completed a wonderful job. I needed a new hot water heater. Within minutes from when I called for a referral, they reached out and called me, scheduled to come out to provide a good estimated price and came out the same day. And within a couple of days, they installed the new water heater, and they did the whole job, in just one day; also at an affordable price. I find them very competent, professional and they were able to answer all of my questions. I definitely will add them to my portfolio of vendors, and call them on a yearly basis. Thank you so much!"

"Midtown Plumbing did a very professional and thorough job of totally replumbing an unfinished basement bathroom. The crew were very friendly and made the effort to thoroughly answer all my questions to my satisfaction. They also added necessary items that I was not aware were required. Their drain line routings were a beauty to see. While backfilling and self compacting prior to the slab pour I was concerned about a soft, moist surface and partially reexcavated a portion of their work. Midtown returned and retested for leaks and verified that all plumbing was good, and at no extra cost. I was very impressed with their honesty, diligence and pride in their work."

"I have used Pacific Crest for multiple plumbing needs over the years. When I first bought my house I needed a sink faucet installed and they came out and did it. They have replaced a hot water heater, and fixed clogged sinks and toilets for me too. They are so fast, well priced, and nice to work with. Plus I know they will treat me right, I have had them out before and Nick will go over what is wrong and if I can fix it with something simple, he tells me. I have old pipes so sometimes it's a clog that just wont get cut but onetime I thought it was that, I tried chemicals, I tried a plunger, nothing. He came out told me what to do with the chemicals and then it worked! They are all so great!"

FAQs for plumbing installation for a remodel or addition projects in Lake Oswego, OR

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.
