"I will never hire them again or recommend them to anyone. While the quality of the material purchased to do the porch was very good, their attention to detail was quite lacking. There was never any trim put around the base of the porch, the holes were not even filled in properly where the concrete piers were placed. The roof repair, which was supposed to be done, consisted of adding several 90° elbows to each of the roof vents, which did seem to fix the issue, but the $1,000 charge for that is a little excessive. The last little bit was the relocation of an outdoor water faucet, which appears to have been done, at least from the outside, but none of the plumbing was ever done inside to hook up that attachment, so it is nothing more than decorative at this point. I feel like I was excessively overcharged for some of this work and some of the work was never even completed."

FAQs for basement remodeling projects in Northumberland, PA

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.
