"I highly recommend Lux Renovations/Owens Corning Basements for refinishing basements. The initial consultant was highly professional and it never felt like he was a ‘salesman’ with high pressure tactics just trying to get his commission. I have never refinished a basement before and assumed it would be the same as any other room in the house but I felt extremely reassured about the materials and methods used to keep the basement in the best condition as possible. When it came to the instillation, I cannot speak highly enough of the people that made it happen. They were prompt, hardworking, considerate, and there was never a moment we were concerned about having people we didn’t know in our home. The results are wonderful. Our basement was feeling like a dingy place we just put stuff but now it is open, clean, and an enjoyable place to be."

The same highly skilled crew has worked at our house for all projects. They are polite and clean up daily. While Liberty Construction has completed three bathroom remodels for us, the pictures below are before/after photos of our latest project, a kitchen remodel. This project involved a complete demolition and moving walls and doorways. The results are beautiful! Thank you, Liberty Construction - we love our new kitchen!"

"I had my 1960s paneled and drop ceiling basement room remodeled. I cannot tell you how pleased I am at the upgrade. Along the way Gary answered many emails and calls in a timely manner, usually within the hour. He gave me updates of when certain parts of the project would be worked on and made suggests on things that I hadn’t thought about ( like replacing the drafty original windows while construction was happening). He picked out doors and ceiling fans that were perfect since I am not good at decorating. Because GJP has all their own contractors there was no wait time between the remodeling of the walls and the electrical work that needed to be done. All the workers were do polite and diligent and cleaned up the area. I cannot put into words how wonderful the whole process has been and have already given references to friends. "

FAQs for basement remodeling projects in Swarthmore, 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.
