We will give you the Basement you've always wanted by transforming your previously unfinished Basement into a usable and comfortable living area you can be proud of.

"We recently had the pleasure of working with Basic Companies to finish our basement, and we couldn't be happier with the results! From the initial layout and permits to framing, electrical work, sheetrock, spackling, painting, and flooring, they handled every aspect of the project with utmost professionalism and expertise. Each team that came to our house was knowledgeable, hardworking, and incredibly professional. They were always responsive to our questions and ensured that we were kept informed throughout the entire process. The project was completed within the promised time frame, and to our delight, it was actually finished much earlier than expected. Our family is thrilled with the final result. The finished basement has exceeded our expectations in every way, and we are grateful to Basic Companies for their exceptional work. We highly recommend them to anyone looking for a reliable and skilled team to handle their home improvement projects."

Properly licensed & insured construction company located in Northern New Jersey.

"We hired the Mazepa Group to gut and reconfigure our master bath. This was a bigger project than we realized and Devin was helpful at every step. He advised us on different ways to configure the space, offered his experience in working with different materials, and was understanding when we inevitably changed our minds on what we wanted to do as we went along. He is very easy to work with. His crews were friendly, professional, and dedicated to customer satisfaction. They took obvious pride in doing careful work and keeping the work area as tidy as possible. We would gladly use the Mazepa Group again."

"Dave provided my wife and me a quote for renovations, and once we agreed, he began the demolition work. The crew knocked down the walls and installed new sheetrock in both the kitchen and bathrooms. We also decided to cut down the sewer pipes and install new PVC pipes. During this process, the first incident occurred when his crew used the bathroom and flushed the toilet, which caused all the waste to flow into the basement due to the unconnected pipes. Dave assured us he would handle the situation, only for us to discover that he charged a purchase of Resolve to our credit card to address the issue. We gradually bought all the necessary materials using a credit card supplied by my wife, while I also went online to shop at stores like Home Depot and Mayfair. After a little over a month, he finished the upstairs bathroom. In the kitchen, he managed to install the cabinets in time for the countertops to be placed. However, while the kitchen sink was installed, the plumbing was not connected to the water supply. Likewise, the kitchen appliances were not hooked up: the dishwasher remained unconnected, the refrigerator was not installed, and the smart thermostat was never set up. Only the stove and the hood range were connected. After he installed the new PVC pipes, I ran the water for a few minutes to test the plumbing. Unfortunately, we experienced flooding in our basement. Water spilled out from our old sewer line, which had not been capped, as well as from the sewer clean-out and all the way upstairs where the kitchen plumbing was not connected. This flooding caused our wood floors in the kitchen to warp and damaged the basement, potentially leading to mold issues. I confronted Dave several times about helping us clean up and remove the damaged carpets, but he failed to show up for two weeks. Eventually, we decided to terminate his services and sought professional help from other contractors. We hired Poseidon Plumbing and have evidence of debris and blockages resulting from the work done by Wise Choice Construction LLC. Additionally, we had to pay for electrical and roofing professionals on top of the plumbing costs to rectify this unfortunate situation."

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.
