"I had these guys put in a heating and cooling system last June. My father is 86 years old with dementia living in this house with the nurse and the heat keeps dropping down to 58° and they tell me they can?t be out there for five days, today is Thursday and they can?t make it out there till Tuesday. I would have to say stay away from this company. "

We are a general contractor so we do have subs that work with us. The advantage is that it is the same crews on every project that we do. We don't bid out jobs and get the cheapest company to do the work and keep the savings for us. We always have the same quality on every project we do.

FAQs for second story addition building service projects in East Hanover, 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.
