"Hubert Construction performed large scale construction/ additions to my home in 2022 and 2024. I had a large addition done in 1998, which I only wish could have been Hubert Construction. It left much to be desired. I watched Hubert work on another house nearby and was impressed. The 2 jobs that they did for me, were absolutely impeccable. Every part of the construction was done exactly as I hoped for, from design, to quality of work, to finished product. That’s why I didn’t hesitate to hire him a second time.

"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!"

"When I decided to remodel my master bathroom I knew immediately to call Matt, the owner of The Finish Guys. It was not the first time I have hired and used Matt and his team and probably won't be my last. Without a doubt, Matt is one of the nicest, kindest, and considerate business owner. He was meticulous with helping me plan every detail of my remodeling. He was by far one of the most reliable, trustworthy, and reasonable contractor I have ever used. Matt was amazing communicating me through the entire process and was always available when needed. I am beyond thrilled with the work Matt and his team did. Thank you Matt for making my dream bathroom come to life. I am so incredibly happy to have selected you."

FAQs for second story addition building service projects in Princeton, 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.
