"Zach diagnosed the problem immediately: a burned out pilot assembly. He attempted to find a replacement part with the information he had at hand, but was unable to do so. He asked me to contact the manufacturer and order the correct part. The manufacturer gave me the part number but would not sell the part to me, a homeowner. So, it took a week for Zach to get the part, then he installed it immediately. Great service!"

"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."

Customers say: Quick response

"Called these guys up to inspect for a crawlspace leak that I was suspect of. They went down into the crawlspace and were able to find two leaks. They also gave detailed other issues they noticed. I was so thankful they told me about those other issues because I had no idea. Once the work was complete they called me back with a full detail on how everything went. The whole process of making the appointment and arranging the work was a breeze. They were responsive, attentive, and got the job done well. I have these guys saved in my phone book for future work."

"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 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.
