I had a pipe repair done, roof work and he also lit my hot water heater and fireplace. Just last week I called he to come check on a leak I had in the attic. I calls Reggie for all my plumbing needs and will most definitely recommend him to all my friends."

A 2016, 2017, 2018, 2019 Super Service Award Winner in multiple categories; including Kitchen & Bath Remodeling. Legacy Builders is a full service, Baton Rouge-based residential building / remodeling and contracting firm. Our many Angie's List Super Service Awards demonstrate our commitment to our client's satisfaction. We specialize in Kitchen & Bath remodeling, but will also help with any remodeling or building project you have in mind. Our desire and motivation for every project is excellence in workmanship and a positive experience for our customers.

"Louis and Glen are the best. They did a full remodel on our master bedroom and bathroom. This included turning flat ceiling into cathedral ceiling, new drywall and insulation, new wood and tile flooring, full closet reworking, new tub and sink, new bath tile, new windows, new mini-split a/c unit, new light fixtures, and new exterior siding. He gave us a timeframe, and sure enough, the project was finished up within that timeframe. No delays, no excuses. All the work is extremely high quality. We told Louis what we wanted, and he worked with us to make decisions that were reasonable for our space and within our price range. If one of our ideas wouldn't work, he'd take the time to explain why. He never tried to push us to anything more expensive than we wanted. He works with excellent electricians (Ray and Francis), excellent painters, excellent sheetrock guys, and excellent frameless shower installers. Throughout the work, Louis kept telling us that all he wanted for us was to have something that would be special for our family. That's exactly what he gave us. After the big bathroom/bedroom remodel, we've gone back to him again for an additional shower installation, some electrical work, and even some roofing. I would trust Louis with any project. Unlike other contractors that we spoke to, Louis is extremely responsive, punctual, professional, trustworthy, and courteous. Most contractors are flaky. Not Louis. He's easy to get a hold of, and he'll be there when he says he'll be there. If he does work for you, you will be his priority."

FAQs for plumbing installation for a remodel or addition projects in Geismar, LA

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.
