"I paid an excessive amount of money to replace the heating system. The sales rep gave us comfort that everything will be done right and the two experienced and fully licensed professionals will be doing the work and that there is a no-excuse warranty, 1 degree guarantee, and 10 years on both the service and hardware. It just so happened that after the install, I told the installer I smelt gas and to check everything. He simply waved it off and said it's fine, give it some time. I told AJ Perri multiple times that there is a gas leak and I asked them to rectify the situation. I called them multiple times to send someone to fix the issue immediately and urgently, but they refused to commit to any resolution and won't send anyone until the gas is turned off for the whole building. I explained that its a condo and that the unit itself in the utility closet has a separate gas shutoff valve. Knowing this, they refused to remediate the gas leak."

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