"I have been a real estate professional in Howard County for over 40 years, first as a realtor and then as an appraiser. In my career I must have seen conservatively over 4,000 houses. I have seen all kinds of renovations and updates to existing properties. I have seen workmanship at all levels, from DIY disasters to premier craftsmanship. I want to share with you an experience I have had with a basement renovation company called GloRem LLC (gloremllc.com). I was first involved with this company 10 years ago when the company was a new venture for the owner, Evgeny Chernousov (â Eugeneâ ). At that time, I found the company through Angieâ s List and took a chance on a young and eager contractor whose bid to remodel 3 bathrooms was competitive in the market. What a serendipitous decision that became. Eugene and his workmen, from tile experts to framers to electricians to plumbers to painters were true artisans, and Eugene was involved every step of the way. He made sure there was a minimum of construction dust and unnecessary clutter. His insistence on expert execution of every task was consistent with what I discovered to be his perfectionist personality trait. After enjoying his exceptional work on my bathrooms for a decade, it became time to both renovate my basement and add a bath. I was delighted to discover that Eugene and his company, GloRem LLC, had become a premier basement remodeling company. After asking him to see my basement and give me a bid, his pricing was still, despite his considerable success, competitive. I was delighted to discover that, a decade later, not only was his work ethic unchanged, but, in addition, Eugene has become a sophisticated version of his enthusiastic and talented younger self. His bid was detailed and easily understood with each expense described. His work, on my second encounter with him, was just as enjoyable as my firstâ ¦all work was completed ahead of schedule in impeccable fashion. I write all of this just to give any of you who are considering home renovations a heads up from a real estate professional who, in 40+ years, has truly â seen it allâ and is delighted that true quality and pride of workmanship still exists."

FAQs for basement remodeling projects in Rockville, 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.
