"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."

"We have used The North Star Companies for several jobs in the past, with the most recent being the largest. We hired them do a complete renovation of our home in Severn. The job grew larger as demo began and turned into a job requiring the rebuild of exterior walls, demo of concrete slabs - basically the house had to be rebuilt from the ground up. All new plumbing, electric, framing, windows, siding, roof, etc. I have known Chris for 20+ years and was confident that our forever home would be solid and done right. We had a few hiccups throughout the process - as this was done during Covid, so there were supply issues, delays and so forth, but Chris and his guys did an amazing job. We couldn't be happier and are continuously getting compliments on our beautiful home. Chris has been and will continue to be our go-to for any construction needs for us and our family and friends."

"Initial rep was great and informative. Felt comfortable with initial sale. Hardly had any contact from customer service except for the payments. There were several delays that we were not informed about unless we called to ask. Took 7 months before they showed up to begin project. Only 1 person was sent to build steps. Took a week. Hard worked, hardly took a break. Had to call again to see when they would come to pour patio. Never knew when they were coming, they just showed up. Hardly spoke with the homeowners. Inspection paperwork was just left on porch. Additional paperwork that is "required by the County" had to be completed by homeowner and taken to Court house to be notarized and filed and also provide a copy back to Long Fence. Time sensitive materials which added to homeowners to-do list. Gave this contract to LF on the surface of their history and appearance of a 'good local company' but should have stayed with original contactors in VA. Puddle of water forms when it rains"

"Excellent, no problems. My car was new the first year I used the service and there has never been any damage during the transports. The men picking up and delivering the car have always been pleasant and cooperative. Both Ely and Guy at United Transport has been highly responsive to my needs. I would highly recommend this company."

FAQs for basement remodeling projects in Great Mills, 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.
