"They were absolutely amazing to work with. Our house is 118 years old and they hadn't been updated since the 70s. They treated my home like their own. I am beyond happy with the end result"

"Hired company for complete deck tear down and rebuild with framing and trex deck. Deck work is amazing and we love the final product. Overall work was great quality and professional. Did have issues at times with completion dates and trying to contact john at times; however, John always got back to me in a timely manner and explained thoroughly what was going on. He will always get back to you and try to reticfy any issues you have, which was very nice to see and witness first hand. Would not hesitate to use this company for any contracting needs you might have. We have another project already scheduled to complete with John's company this summer."

"Bill and his crew are top-notch professionals. We had them install vinyl siding and replace a few doors. Everything was done perfectly. The crew did a great job making sure everything was cleaned up on a daily basis and at the end of the job. That was very important to us having two children that run around outside. I would highly recommend them to anyone."

"Keith did a large, heavily overgrown land clearing job for me. He was easy to work with, kept me advised at all times regarding start up, progress, issues, etc. His work was excellent, very professional. I would definitely recommend him to anyone who wants a job done, and done right."

"Logan and his crew assisted me with our kitchen demo and remodeling. The project involved several phases as cabinets, fixtures, etc. were delivered. He remained flexible to the various obstacles we encountered and helped me do the things I could, (while telling me to get out of the way for others). This young man is professional and serious about what he does. Need a home? he can do that from the ground up. Demo or remodeling? No problem for them. One of his guys, Aaron, is just a great guy! Look forward to working with them all again in the future."

FAQs for basement remodeling projects in Williamsport, 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.
