JBL Home Improvements, Inc, located in St. James, is a family owned and operated remodeling business specializing in residential projects. Owner & Contractor David Kaplan, General Manager Jill Kaplan, along with their team of talented professionals, are dedicated to providing outstanding workmanship and customer service to homeowners who live in their community.

"The project ran smoothly, on time, and on budget. Dave and his team were professional, clarified issues before they became problems, and left no loose ends. The project involved the demolition of existing built-in cabinets and a massive, green-tiled shower that was designed with one purpose in mind - growing mold. We increased the footprint of the 10x11 sq ft room by reclaiming space from an adjacent oversized walk-in closet, which made a perfect alcove for a new free-standing tub. The tile installation was done to perfection, and the installation of all components, including the neo-angle door was completed without issue. To their credit, the team helped us isolate a crack in the new Kohler toilet and installed the replacement part without complaint. We're looking forward to working with JBL on our next project."

Kitchen and Bath Works Inc has been owner operated and successfully in business since 1994. Offering a consultative approach and delivering on quality, custom work, our business has been overwhelmingly driven by word of mouth referrals. From start to finish, we stand by our work and our owner is committed to being present on all jobs.

"Louie did a fantastic job on remodeling our bathroom! He came to provide us with a free estimate and spoke with us about what we needed/wanted. He got back to us promptly with an estimate and a time frame of when he would be able to do the job. Louie did all the work himself and he was prompt, reliable, trustworthy, personable, and great at his job! Before beginning the job, Louie provided us with a clear time line of what he expected to be completed each day and he was always right on schedule. He replaced sheetrock on the walls, he installed a new medicine cabinet, he installed our new vanity, counter and sink, he installed our new sink faucet and shower fixtures, he replaced our floor moulding and trim, and he did a beautiful job tiling our bath and floor! As part of the job, he will be returning to install our shower door once we have our tub reglazed. It's clear that Louie takes pride in his work and he is happy when the customer is happy. We are thrilled with our remodeled bathroom thanks to Louie's amazing work! We will be calling Louie again for future jobs and we would certainly highly recommend him to others!"

"RUN FAR AWAY FROM ALLIED AND TOM. Tom took my money and did not complete the renovations as per our contract. He lied about having a licensed electrician to do electrical work, it was just one of his workers who's not licensed. I paid for a dumpster and when it was delivered by tom it was already half full from another allied job and I was asked to pay the full amount of $950. Tom didn't listen to anything I said regarding the work I requested and he changed my design and did work that was cheaper for him. I was priced for one of my ceiling's to be ripped out and reinstalled with new sheetrock, Tom waited until I was away on business then he installed sheetrock on top of the bad sheetrock and told me he ripped out the old sheetrock and installed the new sheetrock, I found out when my EC cut holes to install lights and we found 2 layers of sheetrock preventing the lights from being able to be installed. Allied construction is a cheap, sneaky company who will steal your money and breach your contract. Do not hire these people Tom is a lair. Tom wore a gun in my house on his hip and told me "I use this to get paid by customer who don't want to pay". Tom left live 120v wires hanging out of the walls and ceiling, he removed a banister and didn't replace it for 3 weeks making my home very unsafe for me and my 9 year old son."

FAQs for plumbing installation for a remodel or addition projects in Mastic Beach, NY

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.
