"Ed and Jaime basically set us up in our new home! It would have been challenging to accommodate all the things Legacy did for us through another contractor. Their work is great but above all they are just solid reliable people you can trust. I appreciate Ed’s honesty and professionalism in ensuring all the moving pieces get done. I had the opportunity to hire few other contractors for separate needs and Legacy stood out in their commitment to do right by their customers and more importantly their own people as well.

"I hired Tony to replace my roof which included a new attic fan and new gutters. He also replaced a very large bay window for me. I cannot say enough good things about him. The price was fair, the workmanship excellent and all his staff professional and courteous. I asked Tony about another window and he suggested I might be able to find someone to repair it rather than paying to replace it. You can’t ask for a more honest businessman! Five stars all around. I highly recommend him!"

Our mission is to service our customers in a prompt and professional manner. We do not consider a home improvement or remodeling project complete until the work is finished, the job site is clean, and the customer is completely satisfied. Licensed & Insured since 1997

"This is an overdue review. I hired Bernie and his team for a kitchen remodel in June 2021, after he did an excellent job with my three bathrooms in 2020. The kitchen remodel was also excellent. His works are efficient, hardworking and clean. My remodel took two weeks, as he had quoted and for the exact price he had quoted. I would hire him and his team again and I referred them to a coworker for her bathroom project. She was also very pleased with their work."

FAQs for second story addition building service projects in Hillsborough, NJ

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.
