"After obtaining quotes from several contractors, we selected BNQ to finish our 1800SQFT basement and put in a bathroom around a roughed in full bath. The team was punctual, professional and left the job site clean every day. The work was done on schedule, and as issues were uncovered (as any project has), they were communicated to us and we worked together to come up with any plan forward. Having used other contractors in the past, I couldn't be happier with BNQ's quality, responsiveness and overall quality of the job."

"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 ."

"After living in our house for 10 years, we had been looking to repair our leaking roof and cover the deteriorating wood paneling on the outside of our house. We started our search at the 2019 Pittsburgh Home and Garden show. We met with a few roofing companies and decided to go HomePro Remodelers. Roberto met with my wife and I and explained the process of replacing the roof. After signing with them, they got started quickly. The crew that replaced the roof were very professional and courteous. They did a good job with the roof and cleaned up the area before they left. The crew leader Marvin was very easy to talk too and answered any questions as they came up. This year we went through the process of meeting with different companies to get quotes to put vinyl siding on the house. After meeting with Roberto, we decided to go with HomePro Remodelers again since they did a good job on the roof. The day after signing up with them, they were already bringing over equipment. Once again it was Marvinâ s crew who did siding, and they did not disappoint. They were courteous and entertained any of our questions. They cleaned up the worksite and the house looks great. After 2 separate jobs with Roberto and Marvinâ s crew I would highly recommend HomePro Remodelers."

I needed my basement renovated ASAP and Mr. Anthony met with me in a timely manner explaining in great detail the work he would perform and how pleased I would be! Let me tell you he did NOT disappoint because he and his partner Mark performed what I call a â  miracleâ  in renovating my basement and went above and beyond my expectations!!!! Iâ  ve shown many the before and after pictures of what I now can call my family room and the response each time was how â  beautifulâ  of a job Anthony did!! If you are in need a great contractor donâ  t look anywhere else but A & J Contractor and call Anthony NOW! My family still canâ  t believe what A & J Contractor did with that old and in bad shape basement!! Very professional and the many years of experience really was on display!! Thank you again Anthony and Mark for restoring our basement!! Iâ  ll definitely be utilizing them in the future and wonâ  t have to look elsewhere!!"

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.
