"Jeff did a great job on our complete basement bathroom remodel last December so we asked him to do a small job of installing a vanity. The job was done quickly and efficiently. The price was reasonable. Everything was cleaned up. I highly recommend Northgate Home Improvement and will gladly hire them in the future."

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"TriBuild Construction did a really terrific job, from the estimate to the cleanup on the remodel of our basement. The owner, Ray, is a super nice guy who clearly knows his work, and he was always available quickly to answer my questions, even some he had already answered. I liked that the estimate was detailed enough for me to know exactly what we were paying for and when we desired changes/additions to our original plan, Ray was accommodating, got my approval on cost first, and he did not overcharge us for them. The workers were friendly and efficient and they offered ideas for improving the remodel, without pressuring us to do them if we didn't want to. They built us a completely new handicapped accessible bathroom, including demolishing part of the basement concrete floor to install new plumbing and drain, and installed all the tile, fixtures, trim, and paint. It looks really modern, beautiful and very functional! They also installed vinyl laminate flooring and base trim in the rest of the basement, a few new doors, garage doors and windows. The job was done in the expected amount of time (except for my own delays!) and on budget, with no surprises, except for how pleasant the whole experience was. This project was done to build a living space for our mother to come home from a nursing home after having a stroke, so I especially appreciated not having any difficulties with the construction to deal with at this time. Uniquely, because of our mother's Medicaid application requirements, we needed to pay Tri Build in full before they were able to even start the work, and this worked out perfectly fine. It was a little nerve wracking to trust someone we'd never done business with before with that amount of money, but Ray seemed trustworthy, and in the end, he absolutely proved that he is! I would highly recommend Tri Build to anyone!"

"We hired Steven to redo our kitchen floor and install a countertop backsplash. Unfortunately, the project did not go as smoothly as planned. The workmen on the first day caused damage to an adjacent floor and did a poor job with the leveling. To Steven’s credit, he immediately acknowledged the problems and arranged, at his own expense, for the floor to be refinished and the leveling redone properly. What was supposed to be a three-day project stretched into months because of these complications, and during that time we often doubted his assurances that he truly wanted the work done right. In the end, however, Steven stayed committed. After many conversations and much patience, the job was completed conscientiously and to our full satisfaction. He also gave us a substantial discount to help make up for the delays and inconvenience. While the process was far more drawn out than expected, Steven ultimately stood behind his work and made sure the final result was high quality. He is a man of integrity who really stands behind his work. This is something to truly be valued."

FAQs for garage remodeling projects in Ronkonkoma, NY

A garage apartment represents a valuable addition to your property when properly constructed according to local regulations. The potential benefits include additional living space for family members, rental income possibilities, and increased property value. 

Your specific return depends on local housing market conditions, construction quality, and ongoing maintenance. Consider consulting with a real estate professional regarding potential returns in your neighborhood.

Building a garage apartment requires multiple permits, with basic residential garage permits starting at $74 in most locations. You'll need separate approvals for structural elements, electrical systems, plumbing installations, and mechanical components. 

Many jurisdictions also require specific approval for accessory dwelling units. Contact your local building department early in your planning process to understand all requirements and associated costs.

Converting an existing garage into living space presents an alternative to new construction. The feasibility depends on your garage's structural condition, foundation type, and local zoning regulations. Key considerations include insulation requirements, utility connections, and moisture control. Research local codes thoroughly, as many municipalities have specific requirements for garage conversions.
