"Service was great from sales, to installation, to post installation support. Very responsive, very professional. It's hard to find in this 'space'--there are a lot of shady people in basement water damage/repair, and this place exceeded expectations. We've had our repair in place for 4+ years, with only 1 small issue on a wall seam crack, and that was fixed within 24 hours of reporting the issue. Stand up place! Thank you for such great service and support."

"TNN managed our new construction and land development project from scratch. Tim caught MANY errors by the Engineer and Architect before they could become a problem. He made many great suggestions to elevate our original plans. Work quality is great and they take pride in everything they do. Nick did an amazing job on our trapezoid windows and carpentry work. We highly reccommed TNN and will continue to use them for the next phase of our project (garage) We would be happy to provide a reference and even show the work they completed for our project.

"My roof was leaking last winter and upon the recommendation of my neighbor (Ani...) I called A K GATSIOS INC and his team came out and evaluated the situation and provided me with a free estimate. I signed the contract because of the quailty work they did for my neighbor as well as the price i was offered for the full replacement of my flat roof. They came on time, worked efficiently and carefully as well as provided me with updates and finding throughout the day. Job was completed to my satisfaction and I have had no problems since I am just excited to recommend them to anyone needing roofing assistance, very professional team who got the job done in one day in winter might I add."

"I cannot say enough great things about this company. They came in to work on our bathroom and immediately they had a great idea on how to change the layout and make it look bigger. They were able to start immediately, they were respectful of our space, and they got the job done so quickly and efficiently. The best part is our bathroom is gorgeous! We are so happy with the work they've done and highly recommend them."

FAQs for basement remodeling projects in Lambertville, 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.
