"Josh and his team did an amazing job with my bathroom. This was a complete renovation - totally gutted and renovated the entire room, including the floor, walls and window removal. I could not imagine the room as it is now. They were always professional, friendly and extremely efficient. They are hard working and always clean and neat removing all trash and debris at the end of the day. I look forward to my next project with Josh and All In One Remodeling."

"Absolutely fantastic experience with Mario and Lauren! They recently completed a full remodel of my house, and I couldn't be happier with the results. From the initial consultation to the final touches, their professionalism, attention to detail, and craftsmanship were outstanding. The team was communicative, respectful of my home, and truly dedicated to bringing my vision to life. My house has been completely transformed, and I highly recommend them for any remodeling project. Five stars well-deserved!"

"We were very impressed by Lux Renovations from the very beginning. The design and quoting process for our basement gym project was well conducted and professional, easy to follow, and thorough. Unlike other contractors we had an estimate the project, a detailed drawing, selected all materials and colors, and had a detailed cost and timeline while the Lux representative was at our house. The Project Management and build team was excellent to work with. Their work was top notch, clean, and completed on time and budget. We couldn't be happier with our basement home gym."

"I live in Stafford, Virginia and Brian came down and did the work for me when he normally works in Maryland only. I’m so thankful and love you. He came to do what he did and went above and beyond. I bought my house 10 years ago almost 11 now and he has helped me enjoy it so much. There was never a top level porch and Brian created our sanctuary. My husband was super impressed with his work. Thank you for helping us enjoy our home more!"

FAQs for basement remodeling projects in Baltimore, MD

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.
