"I had a plumbing issue that I thought would turn into a major headache, but Mahon Plumbing made the whole process smooth and stress-free. They arrived on time, quickly diagnosed the problem, and had it fixed before I could even make a second cup of coffee. They were professional, knowledgeable, and even gave me a few tips to avoid future issues. The pricing was fair, and there were no surprises on the bill—just great service from start to finish. If you need a plumber who knows what they’re doing and won’t leave you with a mess, I highly recommend Mahon Plumbing. I’ll definitely call them again for any future 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!"

"They were excellent! I called while at work and they arrived at my house within five minutes. They explained everything to my mom, who was home, and called me to verify what was needed for the repair. The repair on took only 5 minutes. A few months ago, we had another company fix the toilet. Apparently they did not properly install it and it cause a slow leak. What impressed me is that Cipriano could have really charged a lot and over sold what needed to be done but they did not. They fixed the leak. They were honest, knowledgeable, courteous, quick, and really nice people. I would hire them again and plan to for future projects."

"Hello, I am requesting assistance from a licensed plumber/gas fitter for gas service restoration at my property: 1239 Maple Ave. Baltimore, MD 21227 BGE has determined that the prior gas service was abandoned and is now processing the project as a new gas service line and exterior meter installation. BGE will be meeting me on-site on Tuesday, June 9, 2026, at 9:00 AM to review and approve the proposed exterior meter location. I need a licensed plumber/gas fitter who can either attend that BGE site visit or come immediately afterward to evaluate the work required on the customer side of the gas system. The scope of work includes: - Inspecting the existing gas piping to determine whether any portion can be safely reused; - Extending, repairing, or replacing internal gas piping as needed; - Establishing the new customer-side gas connection point for the exterior BGE meter; - Pulling the required gas/plumbing permit; - Performing the required pressure test; - Coordinating the requir"

"It was a completely positive experience in every respect. Gary arrived on time and patiently went through the house to try and diagnose the new and very frequent “ghost” water sounds throughout my house. Checking the area where water sounds could be originating from, Gary located a joint on my sump pump that had a leak and was causing the trap on the pump not to close completely resulting in the water sounds. He replaced the joint and installed a silent trap which is wonderful because the sump pump had gotten so loud over the years that it could be loud enough to keep someone awake! Then, he snaked out my kitchen sink that was backing up and now it’s draining better than ever. Gary was professional and very knowledgeable, and explained what needed to be done and why. This is the first time I felt like only necessary work was being performed at a reasonable price. I will definitely call on Heil plumbing for all my future plumbing work."

We called Millersville Plumbing after 2:30 pm on a Friday afternoon with a plumbing emergency. A toilet was clogged in the downstairs bathroom.  The emergency was that my mother recently came home from the hospital and that was the only toilet she could access.  Millersville came to the rescue, providing an immediate appointment, fixing the issue with the great customer service they've always provided.  Fixing stopped up toilets isn't a pleasant job, but you would never know it from the plumbers pleasant interaction with my mom.  They also fixed a leak in the toilet caused by a loose bolt.   I've used Millersville Plumbing for all my plumbing needs over the years, from replacing external water line - during winter, snow conditions, installing a new dishwasher, and diagnosing various plumbing issues.  I'm happy that I have an experienced plumbing company that I can trust and that values their customers.  Millersville Plumbing, Plumbers are the best.  :)

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