"Jerry and his team did a fabulous job on our basement egress window. Fantastic communication, before during and after the job. Excellent workmanship. Cleaned up very well after the big job. Flexibly worked with our schedule. Jerry even gave me advice on laying out our basement remodel (we are doing it ourselves) and gave me advice on materials and design. Totally happy. Would recommend C&J without reservation!"

"Asked for a quote on removing an old deck, replacing with a larger one. Price quoted was fair, and we accepted. We're very pleased with the final product, and the whole ordeal was hassle-free for me and my wife. Every worker involved was very professional. Communication from start to finish was excellent, and I feel the job was completed faster than we had expected. Will be using this company in the future for other projects."

"We recently had Your Remodel Pro completely remodel our bathroom. Allen and his crew did an amazing job. They always came on time and made sure to leave the job site clean. Allen spent the extra time to pay attention to the details and did high quality work. We would definitely hire Your Remodel Pro again."

"The price was less than the big name. <br /> They showed up on time, with a full crew, and worked all day. <br /> They finished ahead of schedule- 3 days instead of the expected 4. <br /> The materials and methods are well engineered. <br /> The workmanship was excellent. <br /> My basement is now clean and dry! <br />"

"Frank and his team were wonderful. We had a general idea of what we wanted to do in the basement to finish the space, but Frank helped us figure out the best way to get the look and function we wanted. He also was the most reasonably priced of all the contractors we received quotes from. Frank was great about keeping us updated on the project and always confirmed everything with us before doing it. We even adjusted some of our plans mid-project, and Frank quickly changed what we wanted and made very helpful suggestions that helped us get the finished basement we dreamed of. The quality of the work is fantastic and Frank and his team are very friendly. We will definitely hire Frank again for our next home improvement project."

FAQs for basement remodeling projects in East Nassau, NY

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
