"After consulting with several companies, I decided to hire ESM Construction LLC for the remodeling of my one-bedroom condo. Their pricing was competitive, and Edgar displayed a wealth of knowledge. He was also exceptionally responsive, addressing all my questions promptly. The crew arrived on schedule, and they were both friendly and professional. They completely transformed the condo, installing brand new flooring, ceilings, paint, a bathroom, kitchen, and appliances. I never felt rushed, and every aspect of the project was completed in a timely manner. Edgar and his team were attentive and patient, never once saying, "No, we won't do that!" Finding honest and reliable contractors can be challenging these days. We interviewed several contractors with five-star ratings, but many seemed overpriced, like quoting $5K for cabinets that only cost $3K depending on kitchen size. Some of the five-star contractors even came off as somewhat arrogant due to their reviews, which raised concerns about potential issues. If you spot even one negative review, take it seriously; we’ve paid a steep price for ignoring such warnings in the past. Edgar's team even rectified mistakes made by previous contractors. From the moment we spoke with Edgar, we recognized his down-to-earth demeanor and extensive expertise in his field. We are thoroughly satisfied with our decision to go with ESM Construction LLC and wholeheartedly recommend this company."

"Amazing customer service in every way. Polite, professional and knowledgeable. He went way beyond my expectations for our kitchen remodeling job. Very knowledgeable with good recommendations and even went with us to the cabinet vendor to make sure we got what we needed. When he ran a new electrical line for our appliance, he used only the minimum of the expensive wiring and only charged for that part of the roll. That was just one of the many ways he went out of his way to make sure we were completely happy with his service. When he installed the overhead lights he made sure all the details were covered, some that I had never even thought of. I'd give them 6 stars if I could."

Complete kitchen and bath remodeling including plumbing and electrical. Highly experienced and certified technicians with over 20 years of field knowledge and empierce that will respect your home and delivery an amazing experience that you will remember and share with others for years to come. We can customize any project and work with any budget. You will admire and adore your new space.

"After I terminated the lease of my tenant in early 2023, I decided to do the whole house remodel before selling it because of the age of the house and TLC it needed. The original contractor I hired ended up going to jail for child abuse charges and I had to find another contractor to finish the job. I got a number of quotes and decided to go with Donna from AND Contractors, LLC. It is very difficult to come into a project that somebody else started and the quotes reflected that but Donna’s estimate was fair and I felt comfortable in my interactions with Donna. Don't let the fact that a woman runs the business fool you - she is a real tough but fair boss. She was on the job site every day! She treats her people right but also lets them know when they mess up and they respect her for it. There were many things that were not visible but needed to be redone where the original contractor messed up but it was important to Donna that the corrections be made. I am sure there must be limits but all of these corrections were accommodated without change orders. The project was completed on time and within budget. Oh, did I mention Donna is also a real estate agent? When the project was completed, she listed the house at the highest price in the history of the neighborhood. I was hoping but not expecting it so it was a pleasant surprise when she brought me a full price contract within a few days! I HIGHLY recommend AND contractors, LLC and Donna! If you want your project done right, on time and within budget, you owe it to yourself to at least have her look at your project!"

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