"Recently used Mahon Plumbing for various plumbing needs around my house. As a new homeowner you can be skeptical on what’s behind your walls or in this case pipes. Mahon did an initial sewer line inspection and called them back to swap out toilets and install natural gas in my backyard for a grill and fire table. They were professional, honest, and extremely knowledgeable about all phases of my projects. I would recommend Mahon Plumbing for all of your plumbing needs!"

"Everything went great. They were able to set up an in-home estimate. Derrick is courteous and professional, and was able to get me an estimate quickly, and was even able to accommodate the work the same day, cleaned up after the work, and walked through the features of the installed hardware with me. Very highly recommended, and would definitely call them again for any plumbing work!"

"Rema was very thorough when installing my new kitchen faucet. He came to my home at 6:15pm, which surprised me. In my experience, it’s difficult to get a plumber past 5pm! My faucet works perfectly and he was very nice. He said he has been doing plumbing for 20 years! I think I have found my “go to” plumber!"

"I originally called Third Generation to give me a quote on a partial master bath remodel. Robert and Christina came to the house together and gave me some good advice on what needed to be done and a ballpark figure for the work. They also explained that they flipped houses and had trusted people who could do whatever else I wanted to have done in the house and could do it fast. Shortly thereafter, my circumstances changed and I decided to do a full master bath gut and remodel along with a long list of things I had wanted or needed to do for years. Robert gave what I considered a fair quote for my VERY long list of jobs and had people on site within days of signing the contract. Everyone working the job was pleasant, hard-working, and highly skilled. I felt very comfortable with all of them and had no reservations about having them in my house when I wasn't there. The whole job took about 8 weeks but 2 to 3 weeks of that was because a special-order vanity arrived damaged and had to be re-ordered, delaying the completion of the new master bath. I am delighted with the job(s) done by Third Generation. My master bath is gorgeous, my laundry room is now attractive instead of an eyesore, and a long list of "I hate that"s has been turned into "I love that"s. For the amount of work I had done and the range of different types of work involved, the speed of completion, even with the delay caused by the defective vanity, was really impressive. I will definitely call Third Generation again not only for plumbing work, but for future remodeling that I may decide to do. This was a great experience and I have no hesitation in recommending Third Generation."

"I have had Ehrhardt plumbing for numerous plumbing jobs. The Roman Tub Faucet installation was probably the least successful job but still OK. The tech left and the faucet was on a constant drip/flow. I had to call and have the tech return. He said he needed a replacement part. Since the faucet was one I had ordered online -and from company Ehrhardt does not deal with, I needed to find it. I eventually did. The drip fortunately stopped. I still wanted someone to come and recheck it -- didn't seem to work that great. I was told I would have to pay for the recheck. I was disappointed considering I have been a good loyal customer. I opted not to have him come. Previously they have replaced two hot water heaters. I would still call them because for the most part the service has been satisfactory."

"Ike repaired the exterior hose faucet and replaced the kitchen faucet with great attention to detail. He assessed the repairs and gave us an estimate prior to doing the work. He is very informative and professional. I highly recommend Ike and Heil Plumbing for any plumbing project."

"The kitchen drain was snaked but a vent and a clean out needed to be installed. The company that did my kitchen remodel did not do a good job. After they installed a vent and clean-out the line was snaked again. A few days later I noticed Water in another part of the house. It was a leak in the main stack. It seemed that the cast iron pipe had rusted and with the snaking, it developed a hole. My house was built in the 1920?s and this was the original stack. These plumbers were able to do it all and at a great price. Much, much less than I would have paid through some of the other plumbing companies. I will use these guys again and again. Everything was explained and I saw the problems with the pipes. I was impressed that they showed up when they said they would and if they were running a little late they would call. They are able to do the job quickly and effectively. They are and A+ in my book.

"We needed to replace a toilet, James went with us to Home Depot to select one. We now have a water efficient and higher seated toilet, which is great for aging relatives that can’t bend so easily anymore. I would definitely hire/contract him again!"

FAQs for plumbing installation for a remodel or addition projects in Crownsville, MD

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.
