"When we asked all our friends/family/coworkers for a good contractor recommendation all we heard were horror stories. But thank god for Angies List and Carmen! We got a few estimates for our job before hiring Carmen, but Carmen stood out as the most detail oriented and attentive contractor we met with by far. His quote wasn’t the *lowest* estimate we got, but it was definitely the best justified based on the time and attention he gave us in reviewing all aspects of our job and answering all our questions. His attention to detail and genuine care for the quality of work he does carried through our entire renovation. From the temporary shower he built in our basement (to use while our only bathroom was under construction) to the perfectly aligned tile in our shower enclosure - everything was expertly planned and executed. Carmen was great about communicating next steps as the project progressed and we felt confident about his work during the whole process. On top of being great craftsmen, Carmen (and his helper Ryan) are just all around friendly guys that were a pleasure to have in our home for a few weeks. We’re so happy we found Carmen and now we finally have a great contractor to refer to others!!"

"The owners (Chris and Cal) did an excellent job on our remodeled project. They were personally involved with the project and worked directly with us during the entire planning and implementation of the work. They were true craftsmen. We wanted a contractor who could do the entire project and C&C fit the bill. They performed the drywall, flooring, windows, painting, electrical, and structural part of the job. We would highly recommend them ."

The arrived 10 minutes later evaluated what needed to be done and told me they would come back later that day. They came back when they said they would and repaired my steps. They look great! I would definitely rehire them! Courteous, no double talk and, they listened to what I wanted!"

"I hired him to do a pretty significant remodel on a duplex investment property. The building was old and had a lot of subpar work done by the previous owner that had to be fixed. He worked with my budget and stood by his work as he actually fixed a leak in the roof 2 months after the work had been completed. Anthony was a great partner as he told me exactly what to expected and helped me save money where possible. His knowledge of the investment/rental perspective helped me reach my goals with the duplex. I plan to buy again and will definitely be using Anthony and team for any work needed."

FAQs for basement remodeling projects in West Mifflin, 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.
