"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"

"We hired Frank and his team to finish our basement, and we are glad we did! They did a great job framing out the basement, hanging drywall and laying a cement floor. He also added high hat lighting. Frank had a lot of good ideas throughout the project, including making a utility closet. They finished in four weeks like they said and did high-quality work. Best contractors we have worked with!!"

"Wally and his crew do incredible work, are professional, pleasant and conduct themselves as gentlemen. Wally discovered significant water and termite damage during the onset of a home remodeling project. Wally was transparent, supportive and most of all reliable when giving us options. We're very pleased with the work thus far. Wally has reinstilled my trust in the General Contractor industry. I highly recommend Wally and his team. I plan to utilize their services again in the future once these initial projects are complete."

"Brian was with us from start to finish with our combined garage, powder room, laundry room remodel. He has an incredible attention to detail and he really cares about the quality of his work. There are very few problems that Brian cannot solve. He is also very creative, practical and talented. He works with great subs who showed up on time and did great jobs with the remodel. He and his crew were a pleasure to work with. Thanks Brian."

"The crew did a wonderful job, turning a bare cement basement into a cozy getaway. They framed up and insulated the walls and painting the ceiling black to make it seem larger. They also fixed some rotted railings and installed two new basement windows. Very professional, and were careful to keep things clean."

"I recently hired Diamond Interiors to remodel my home, and I couldn’t be happier with the results. From start to finish, their team was professional, detail-oriented, and truly committed to delivering top-quality work. Every step of the project was handled with care, clear communication, and craftsmanship that exceeded my expectations. The transformation of my home is incredible—beautiful finishes, clean lines, and thoughtful touches throughout. They stayed on schedule, kept the workspace tidy, and made the entire process stress-free. It’s rare to find a contractor who combines skill, reliability, and pride in their work the way Diamond Interiors does. I highly recommend them to anyone considering a remodel. Outstanding job—thank you, Diamond Interiors! From Dan W."

FAQs for basement remodeling projects in Philadelphia, 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.
