Kitchen cabinet showroom

"Terrible. Just terrible. Whenever we had a conversation about what was included in our purchase or not, he was ALWAYS switching up his statement. Lou is full of empty promises and we had a poor experience with him. He recommended his brother, Chris Mellilo, to be our contractor. Upfront he seeemed like a good guy but it was our mistake. It took this guy over 6 months to complete 1/2 of our kitchen. BEWARE of Northeast kitchen and his rude and flakey brother who ruined our lives for over 6 months. Find another place to get your cabinets and do not listen to these guys. Terrible, just terrible."

FAQs for second story addition building service projects in Concord, NH

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.
