"C&J did an incredible job completely gutting and remodeling our 1895 farmhouse. This was a huge 8-month job with the variety of complications and required changes an old house can throw at you; throughout the process Craig and Jerry offered excellent design suggestions, collaborated very well with our architects, worked diligently to stay on budget, and each day demonstrated craftsmanship and professionalism of the highest level. C&J’s team of subcontractors and designers are excellent too. These people are the best the building trade has to offer: conscientious, skilled, creative, and a pleasure to work with. Hoping to have them back soon to remodel the guest cottage and garage! See Photos here: [*** Link removed ***]"

"Artie was exceptionally professional and knowledgeable in a vast array of services. Artie worked for me for over 7 years preforming tasks that varied from converting a small shed to a luxury air bnb, remodeling apartment buildings, restructuring and replacing a large porch, installing washer and dryers as well as dishwashers, and various small home projects. Artie was always punctual and reliable. He completed all jobs in a timely and effective manner. He also fixed projects that were done improperly by other contractors. I also found him to be cost effective in every way. Saving myself time, money, and energy upon every job that I hired him for. Artie still works for me to this day. Heâ s my go to for just about anything and everything!"

"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."

"I'm writing another review for T&T because after he did the work on my roof, he gave me a call to make sure everything was going ok and I was happy with the work he did. I thought that was pretty decent of him.

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.
