"Frank did a great job! He was careful to protect surfaces so that there was not a lot of dust and dirt. He replaced a drywall section and plastered and painted. I am very happy with the results. I will hire him again! "

"I donâ  t know where to begin to say how satisfied I am with A & J Contracting! 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!!"

"From the initial estimate and quote to the actual execution of the work, Pedro and his team did a fantastic job. They were diligent, consistently on time, accommodating of our requests, and completed the basement finishing—approximately 700 sq ft—in just three weeks. We couldn’t believe the pace of their work. The quality was excellent. Keep up the great work, Pedro!"

FAQs for basement remodeling projects in Irwin, 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.
