"Hired them for 3 projects I have installed this basement waterproofing solution in 2 homes. System speaks for itself. Nothing better on the market. Work was first rate. Expectations were presented prior to the project. Details on what would happen and how the project would go. Would not hesitate to use again ERV installed New basement egress. This project did not go as planned, but not at the fault of basement systems. Was originally supposed to get a BILCO door but due to unforseen issues, that was not able to happen. They ended up installing a new staircase from my basement to ground level. Work was first rate and ended up better than a bilco door. Company re landscaped and everything is as it was. All work performed was top notch and no issues on anything they have done"

"Penate Tile is great, I had them refurbish a basement room and build a screen porch and both projects were excellent. On time, affordable, and great craftsmanship."

"While we have not done the project the team was helpful with getting things sorted out until we are ready to pull the trigger. Mike Walsh was particularly helpful and responsive. When we do the basement we will reach out to Dewar again to actually perform the work."

"Eugene and his team did a fantastic job finishing our basement! The quality of their work was top notch, and their prices were reasonable compared to other contractors. They were extremely responsive throughout the entire process with any changes we requested or questions we had. The work was completed on time, and included a beautiful half bath and wall-mounted desk. They even did other small favors around our house that were outside of the finished basement, which was very convenient for us. Despite challenges presented by working through the middle of a pandemic, this did not affect their schedule at all, and we came in right at our budget. We cannot recommend Glorem enough, and would absolutely use them for any future remodeling projects!"

"I love my basement now! They removed all of the asbestos flooring, adhesive etc. and installed my new floor in 2 days. The employees were very respectful and worked efficiently. They had said 3 days but they hustled and did it in 2."

"A&N have been wonderful! They did a great job on the bathroom remodel I needed done on a typical cramped 1950s style bathroom to make room for my mother with her walker. They were able to create so much more space and put in a beautiful walk in shower that works perfectly!"

"Willie and his All Things New team did beautiful work for us on a large remodeling project (kitchen & bath) in 2017, so when we decided to do additional repairs and add a second-floor bathroom to our Fellâ s Point townhouse, he was our first choice. We were not present for most of the work period, and we knew we could trust him entirely â both to carry out the remodel and to supervise other professionals (e.g., a stonemason, electricians and plumbers) to do good work at a fair price, on time. The results exceeded our expectations. Willie brings formidable expertise and management skills to his work. He gave us excellent advice on design, and went far beyond his formal responsibilities (and the original contract) to create a beautiful and functional space at a price we could afford."

FAQs for basement remodeling projects in Gwynn Oak, 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.
