"I had a clogged kitchen sink. I tried a variety of methods but the clog got worse. Sewer Renewal Specialists sent Tony to assess the problem and unclog the drain. Tony identified a cleanout right under the sink and unclogged it using a plumbing snake through that cleanout.. The water drains fine now. I'm happy with the work done and with the company's prompt response to my issue."

"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."

"EXCELLENT! It was a somewhat emergency call because my walls were being damaged by the water, and Matt replied right away to my call trying to fit me in. He text back and said one of his guys, Ryan, was available and on his way! Ryan was great! Courteous, professional, punctual (and bonus - he unclogged the bathtub drain!). Thank you for saving the day!"

"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!"

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.
