Hennig custom woodworking has a showroom and shop on long beach Road in Oceanside ny. 1/4 mile south of merrick rd.

"We now have a third beautiful new closet designed and built by Jim Hennig and his team at Hennig Woodworking!! Jim is that rare individual who is truly nice, communicative, creative, reasonably priced and a meticulous master craftsman. Three years ago, Jim designed and built 2 closets and a built-in bookcase for us. We were so happy with that work that we didn’t consider anyone else to design and build our new closet. This project from beginning to end was perfect. He started and finished when he said he would and cleaned up as he worked. Just a great experience - We highly recommend Jim if you are considering any woodworking project. Many thanks to Jim!"

FAQs for second story addition building service projects in Central Islip, NY

For many homeowners, building up is worth the expense because it provides the extra bedrooms or living areas that can’t be accommodated within the existing footprint. A larger, updated home often commands a higher resale price, recouping a sizable share of the project cost while allowing you to stay in the neighborhood you love. Run the numbers with a real estate agent and contractor to ensure the expected return and day-to-day benefits align with your goals.

Whether it makes more sense to build up or out depends on your lot, budget, and local code. Building up preserves yard space and involves less foundation work, but you may need to vacate the home during construction. Building out avoids staircases and can proceed while you stay put; however, it encroaches on the yard and may face setback limits. Compare both options with your contractor before making a decision.

A structural engineer will first inspect the existing foundation for cracks, footings, and load capacity. Depending on the findings, the crew may pour new concrete footings, install steel or concrete piers, add reinforced beams, or tie additional rebar into the slab. These upgrades redistribute the weight of the new floor and bring the structure up to code. Your contractor will outline the specific reinforcement plan and timeline once the engineering report is complete.
