"We live in a daylight basement of a 3 story home we share with family members. We had a ceiling leak and didn't know whether to call a plumber or hvac professional. On advice from a friend, I went with a plumber who we found through Home Advisor - Platinum Plumbing. They came the next day, lifted the ceiling tile to determine the location of the water leak. They determined it wasn't a plumbing leak, but an hvac leak. They informed me that the original contractor had never sealed the hvac pipe coming from the stove exhaust fan vent from the floor above. They said that condensation from that vent was the reason for the water leakage. Though it wasn't technically a plumbing problem, they offered to seal the hvac pipe with a sealant preventing future condensation leaks. They charged me $140 which was the hvac fee which was lower than a plumbing fee. I am pleased! They gave me names of 2 local hvac repair companies if we needed. For future plumbing issues, we will not hesitate to call Platinum Plumbing again. We have learned to trust the professionals we have used from Home Advisor. Home Advisor is our "go-to" resource now."

"This is the only plumber we ever use--and we have issues with our elderly plumbing system several times a year. Reasonable rates and no nonsense. Noel is a down to earth guy who really knows his stuff. Call nobody else. Seriously, if we ever move out of this area, we plan to take him with us!"

"One could not ask for much more with Vlad from AWP. He was willing to take the time to discuss what he was doing and explain options. His work is very neat and precise and he maintained a very clean work environment. As someone who does most of their own work, I can assure you that I will utilize AWP for all my plumbing needs in the future."

"They provided me with information about repair of three 23 year old builder grade toilets vs replacing them. Gave me price options for toilets that would meet our needs, arranged for removal and installation within a couple days. They were here on time and within 1 1/2 hours had removed all 3, cleaned where the old toilets had been, hauled them away and had installed and caulked all 3 and were in their way. Their plumbers were respectful, friendly and professional and did a great job. I would recommend them to anyone and will definitely use them for future plumbing needs."

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