"I hired this company to check an error code on my water heater. They informed that the anode rod needed to be replaced or I could just replace the entire water heater. They gave me several quotes including $4800 to replace just the anode rod or $4500 to replace the whole water heating unit, but wouldn't show me pricing details. I told them to move forward with the repair and afterwards he could walk me through the details of the pricing. They charged my card for $4127 plus tax. I asked to see an itemized invoice and was told I would be sent one when the technician completed his notes. I later received a one line item invoice for $4127 plus tax for a 50 gal electric water heater replacement, several photos, and nothing more. I looked up the retail cost of my new water heater and it is only $825. The average cost in my area is $1000-$2300 for installing a replacement water heater of its size and kind. This company will overcharge you. I?ve filed with the AG for price gouging. "

"Ohana is a very conscientious company to work with. Scheduling was easy, getting an appointment that was timely and worked with our schedule. Calvin arrived on time, keeping us informed by phone that he was on his way. Calvin was professional. personable, and kept us informed as he worked, answering all our questions as he went along. We felt the charges were reasonable. All in all, very happy with the work that was done. Would not hesitate to recommend Ohana, and especially Calvin. We definitely call them again as needed."

"I found the leak in the attic and knew exactly where to find it. I had to let them go through my room ceiling after looking at where the burst was located. No way they could get to it any other way. Job done in an hour. Is $1k to expensive? When 1000's are experiencing the same issue? No you do what you need to do to come back online. I was happy with their business. They explained how to avoid this in the future."

"In 2020 Eco Electric installed a Whole House Fan in our home. It has worked well for us and helps cool our home in the summer. Recently it stopped working. I called Eco and they sent Kyle out to diagnose our problem. Kyle was able to quickly isolate the problem to wiring in a recently installed smoke detector. He was able to fix the matter and get us back up and running. I do recommend Eco."

FAQs for plumbing installation for a remodel or addition projects in Bothell, WA

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.
