"At first the company seemed super helpful. Eric was always pleasant and seemed to be supporting us. HOWEVER, they told us that they were dealing directly with insurance and that we wouldn't need to worry about anything. Therefore no costs, no options, no explanations of services were ever given to us. When the bill came back higher than insurance would cover they assured us that Joyce was the best in the business and would get it taken care of for us. the gap ended up being $3000 out of our pocket and as far as I can tell, no genuine effort was made to come to an agreement because we would have to pay it anyway. They were not actually working for us. In addition, the whole process was frustrating because appointments were made with us, where we canceled plans and they never showed or called. They removed equipment before it was dry and then covered themselves by putting it back in. At the end of the day our house is dry as is our bank account. I DO NOT RECOMMEND!"

"This company offers fair pricing and quick response times. I made an appointment for an installation of a new kitchen faucet along with two angle stop valve replacements. Bill and helper arrived right on time. Friendly and ready to work. They went straight to work and completed the job promptly, testing and checking the system thoroughly. Bill also made me aware of some future services to consider in a knowledgeable, non-pushy manner. I certainly will think about it and give Warren’s a call when I’m ready."

Usually, the two most important questions you want to be answered are… What’s wrong? …And… How much is it going to cost? At Luke's Plumbing, we don’t have a problem giving you a price over the phone. Many Houston homeowners who call us are frustrated because they have called other Houston plumbing service companies and have gotten a run-around when it came to getting a price. It is sad to admit that our industry is plagued with plumbers who intentionally will not give you a price or even a ballpark estimate over the phone because they want to get in your home where they can pressure you face to face into spending more than you should. One of the highest numbers of complaints to consumer protection agency is for home improvement and service companies.. Plumbing license: MPL 37466. A/C license: TACLB 53102E. Call us today for all your plumbing needs!

"Joe D. was prompt, courteous, and efficient! I recommend Luke's Plumbing and Air wholeheartedly."

See that man in the middle? Yes, that’s me…Ryan Stegent. And, yes, those are ALL my kids! Those children are the ones that motivate me to work hard and do the very best job I can every single time. Oh and by the way, I’m a 3rd generation plumber with over 30 years of experience. I’m a product of over 60 years of plumbing and that is something you can put your trust in! Please call or click for a free estimate today!

"I can’t say enough about Ryan Stegent Plumbing!!! As with any home service, one expects courtesy and care for one’s property. From the first contact to project completion, Ryan was a consummate professional. Ryan and I were in continuous communication related to the job. He was very responsive to questions and flexible to my schedule. When he got to my house, he had everything he needed to do the job and did exactly what I asked him to do. No negotiating an easier path. I really appreciated that. When all was said and done, Ryan had done a superb, professional job despite the heat in the attic (over 120 deg F). If one can do a professional job under difficult conditions, I’d trust him to do any work on my house. I would hire this guy in a second for any future plumbing job. Oh, it was also a nice touch that he charged what he said he would."

FAQs for plumbing installation for a remodel or addition projects in Katy, TX

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.
