"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."

"Jose and his team were great. They came in with the lowest cost for the conversion of our garage to an ADU and did a great job. It took them a while to get started but once they did the pace was quick and we are very happy with the final product. Due to unforeseen complications having to do with our plumbing the final cost was a bit over budget but the communication about it was good. I priced three other contractors and I am glad I went with J.A.K.E. Renovations."

"Best Homes LLC just finished our basement and we could not be happier! The quality of work is outstanding and the team was always on time, happy to be here and great at communicating. Jefry is a great project manager and always takes your input regarding placement of different aspects and fixtures. It was a lot of fun working through picking out different tiles, flooring, cabinets, colors, etc to make the space how we envisioned it. We even got to choose the placement of extra outlets and things to make the space fit for our use. The price was very reasonable, especially after being quoted nearly double from another contractor. Our basement turned out absolutely gorgeous and now we have a functional, finished space with a full bathroom and wet bar included. The team was incredibly accommodating, gave a generous allowance for tile and flooring, etc. The project was finished with the quoted price and on time, and we will use Best Homes LLC as our go-to for any contracting needs. 10/10!"

FAQs for basement remodeling projects in Germantown, 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.
