"Hired them for 3 projects I have installed this basement waterproofing solution in 2 homes. System speaks for itself. Nothing better on the market. Work was first rate. Expectations were presented prior to the project. Details on what would happen and how the project would go. Would not hesitate to use again ERV installed New basement egress. This project did not go as planned, but not at the fault of basement systems. Was originally supposed to get a BILCO door but due to unforseen issues, that was not able to happen. They ended up installing a new staircase from my basement to ground level. Work was first rate and ended up better than a bilco door. Company re landscaped and everything is as it was. All work performed was top notch and no issues on anything they have done"

"The job turned out great and we are very pleased. We have been using this contractor for many years and have always been completely satisfied with the work done. Before we moved to a condo, we had a three story house and he did many jobs for us from replacing the roof, to installing a sump pump in the basement."

"Bob and the crew really did a great job with painting our living room and updating our basement family room. The family room project included painting, new ceiling tiles and updated LED lighting. They paid attention to details and provided excellent suggestions that really made a difference. They are locally based in Aston . We will definitely hire again for future projects."

"This was an amazing experience, we had never done a renovation like this before and it was due to a pipe exploding in our basement. Not only did Perry and his team do an incredible job, they were unbelievably patient and understanding as we dealt with the insurance company and all the hassles they create. Their experience, craftsmanship, and tremendous customer service made this a wonderful experience and our new basement looks incredible! Thank you all again! We will definitely be using these guys for any future renovations/contracting work."

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.
