"Pedro Galvan replaced my garbage disposal. He was prompt (always a plus to me, as I've experienced delays without phone calls in the past), he worked quickly and efficiently and removed the old garbage disposal. He is an excellent resource."

"Elsy ( I believe she was the plumber from your company via Angi) arrived as scheduled, on Saturday, 09/28/2024. She attempted to repair my garbage disposal unit but was unable to do so as the unit's wiring was worn out. I advised the unit is 40 yrs old. She recommended to purchase a new one. We made a trip together to the local Home Depot store and I purchased the same brand s she recommended. She installed it in record time (within the 2.5 hrs) and completed the job. She also cleaned the work space and carried the old one to my recycling bin. Very satisfied with her work. Also, I want to know if I will receive a billing statement for my records? Thank you for your time & assistance."

"I have to give this 3 star rating based on price. 5 stars for customer service, promptness, courtesy and professionalism. The gentleman that provided me with the estimate was top notch. NO pressure, 100% honest and generally very respectful of my interaction. However, the price quoted is, without a doubt, not realistic. I searched online for furnace pricing and a very high quality and highly rated piece of equipment averaged around $2500. But my quote for a new furnace with installation was $7500! This is totally unacceptable! Furnace replacement is not rocket science. As a very handy guy, and one who has, first hand, witnessed an installation, $5000 in labor for a 4 to 5 hour job is just way more than this is worth. $1000 per hour is more than lawyers and doctors charge. And there is no flexibility on this pricing. And I don't feel that the months overhead of this company should be charged on each and every installation. Additionally, I received quotes from 3 other companies and their pricing is almost identical. Price fixing? Taking advantage of consumers? You make the call. BUYER BEWARE!"

"Finally!  A plumber that shows up on time and does efficient and neat work.  Also doesn't aggressively try to upsell you on other services.  One more thing, we supplied the faucet to be installed and there was no attempt to charge us for the lost commission  the company did not get on the sale for the faucet.   In other words, just what you should expect from a plumber."

"Service plumber arrived on site, on time and was ready to begin. He was friendly and professional. He was fully aware of the problem and what needed to be done. He acquired the necessary parts and changed them accordingly as proficient as possible. Our bathroom sink drain issue was completely resolved and ready. Thank you Eric for a great job!"

"The plumbers showed up on time, were very courteous and polite. They advised me of all the small problems that came up before just fixing it. After they left a plasterer came in and repaired all of the holes in the walls to change out the plumbing. I had minimal problems and would surely recommend this company.

"We chose EDI after some research and recommendations from friends who also hired EDI to remodel their home. We felt that we can trust this company to actually deliver what they say they will, and we were not disappointed. The crew was incredible and the results show. We are very happy not only with the final result but also very happy with the process and the way things were handled from day one. We think the price was more than fair and we are very proud at our new bathroom and living room space (added lights and painted) and we will use EDI again for our next planned project as well."

"I thought it was really expensive because I got a 7 years contract.  They gave me a 50 gallon water heater because the specs were changing the following month for what’s required for water heaters so they gave me one that was bigger than I needed. It worked fine."

FAQs for plumbing installation for a remodel or addition projects in Lagunitas-Forest Knolls, CA

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.
