"We paid thousands of dollars to AJ Perri for a new hot water heater and have had nothing but problems ever since. I?ve made multiple calls, they?ve sent technicians out multiple times, and the issue is never actually fixed. I?ve even had to call NJ Natural Gas more than once because AJ Perri couldn?t resolve their own installation issues. Their so-called ?Exceptional Service Guarantee? is complete bullshit. Right now, I once again have no hot water?which their own website clearly states is considered an emergency with service promised within hours. Instead, I?m being told they have no technicians available and I have to wait until tomorrow. Meanwhile, I?m left worrying about frozen pipes and further damage because of their incompetence. This is hands-down the worst service experience I?ve ever had. Overpriced, unreliable, and zero accountability. If you?re considering AJ Perri, do yourself a favor and look elsewhere."

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