"I had Henco help with my new home water conditioner installation(pre-brought from Pentair). The job was done super well and the guys(Nolan and Zack) who came out were very professional and willing to explain all the little details about what I needed to know about the system and the plumbing work. I am glad I hired Henco, and I will definitely go back to them if any plumbing job is needed in the future."

"I called Henco’s after I had another company come out and give me and estimate and to look at our water heater. The first company immediately gave me the doom and gloom “this water heater’s going to blow up at anytime, you need to replace it today”! (They just so happened to have a new one in their truck) I said I’d get back to them and then promptly called the second plumber on my list. The owner was very kind and gave me his opinion without trying to get business. I asked if he could come out and give an estimate on repair/replacement, he had someone here within a couple hours. Owen was very nice and honest, he said our water heater was NOT going to blow up, but it was leaking (we already knew, that’s why we called). He didn’t push any sales on us but we asked for a quote on replacement. His quote was MUCH less than the previous guy and Owen explained the differences in the water heaters available. We placed our order, a few days later they came and installed it. The two guys who came were very nice and professional, did an awesome job and answered all my questions. I HIGHLY recommend this company."

"Ryan and Matt were awesome. Matt was very quick on replying to my quote request and getting me a price. Once I chose them for my water line replacement, they moved quickly. Ryan was great while on the job site; kept me updated on what was going on, answered my questions, explained why they used certain products, etc. Matt was there off and on throughout the morning and he was very good to work with as well. They use Steve from Evergreen Boring LLC and he was really great to work with as well. I will be using them again for additional plumbing projects. Their price was very competitive to other plumbing companies."

"Immediately responded to schedule appointment and friendly. Technician was helpful with an estimate and quickly replaced the faulty expansion tank. However, the amount of communication by phone and text from the dispatch was on the verge of nagging and the tech cancelled the appointment the morning of. Got rescheduled and it worked out though. "

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