Classical Pavers serves both New Jersey and New York in the Tri-state area. We are masonry contractor company that specializes in the installation of outdoor living areas including paver driveways, walkways, patios, steps, stoops, retaining walls, culture stone, and fire pits. We are fully insured.

"Classical Pavers did a beautiful job replacing my front walkway! It was not a straightforward project because it was built on a steep slope with a curve. The owner Thiago, who oversees the project, was a pleasure to work with -- never used any pressure tactics, was very responsive to any questions, and gave a fair price. The two craftsmen who did the work were amazing! They arrived promptly every day, worked extremely hard, and did absolutely beautiful work. They hauled away all the old materials and tidied everything up when the job was done. We definitely would hire them again for a future project and highly recommend them."

Second story addition building services FAQs

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.
