"Basic Bassments did a wonderful job in waterproofing and remodeling our basement. Everyone I dealt with was courteous and very professional. The workmanship was really good…township inspectors commented on good the electrical and plumbing work looked. Basic Basements was always on time and cleaned up after themselves. I highly recommend Basic Basements and would definitely use them again."

"We love our basement remodel. Peter, Alex and his team were here when they said theyâ d be here, completed the job as described, and kept us updated along the way. The basement now looks and feels clean and bright. The additional space doesnâ t feel like a basement at all and is enjoyed by the whole family. We highly recommend Lux Renovations."

"We hired Heartland Village General Contracting and Handyman Services to execute a full, top-to-bottom renovation of our bathroom at the beginning of March of 2026. This was a major project involving demolition , new flooring, updated electrical and plumbing to accommodate a new layout of the bathroom. The company manager/owner, Harvey, was excellent. He provided a detailed project schedule before work began and proactively communicated every step of the way. The quality of the final product exceeded our expectations. Harvey's attention to detail truly made the difference."

FAQs for basement remodeling projects in Allentown, NJ

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.
