"From the time of our first conversation to our consultation and throughout our entire project Demetrius was there every step of the way. We had a vision of what we wanted for our patio and deck, Demetrius made sound suggestions and the project was implemented. Project completion time was estimated to be 2 weeks, weather permitting. Demetrius and his team completed the job with efficiency and kept us totally informed as to what phase his team would be working on each day. We are so in awe of our new outdoor space and will definitely be utilizing our outdoor space more often. We are so pleased with our new backyard. What a big difference this has made! Thank you for an extremely pleasant experience! We would definitely recommend Simmons Handyman Service for your remodeling needs and certainly will be using them again when we are considering another project."

"Melvin and his crew are outstanding! I was amazed by his skills, professionalism, honesty and care. I reached out to him desperately on a Sunday, after the first person I hired did not come with the proper equipment to paint the interior of my home. Melvin came out to do the job THE SAME DAY. I gave him more to do when I realized he had a broader skill set. He wrapped up the entire project: painting, lighting, cabinetry AND custom shelves in two days. I will definitely hire him again as I map out other home improvements projects I’ve got left to do."

"We had a complete bathroom remodel including tub removal and install shower with tile and glass doors. Workmanship was excellent and contractor easy to work with. Communication was great and we are happy with the remodeled bathroom. It dazzles! We have had some additonal work done in our basement knowing Dreamville would do the same high quality work. We're very satisfied with this project as well."

"I highly recommend Alex and his team. APX Home Improvement did marvelous work with several renovations to my house. Alex consulted closely with me on a number of options and made numerous helpful suggestions, creating an outcome that was even better than I originally envisioned. The finished basement has been transformed into a larger and attractive living space. APX did an excellent job with renovations on the basement, an addition, the stairwell, two bathrooms, a kitchen, and replaced windows, numerous internal and external doors, and over half the flooring in the house. Their exterior work on the patio was the same high quality as the interior work. And the price was very affordable. I am delighted with the results."

"We hired General Remodeling Group to renovate our DC home and add master bedroom and mudroom additions. They handled everything from the design and permitting (via their architect), to building the foundation, framing, additions, remodeling a bathroom, widening hallways, installing flooring, drywall, HVAC, electricity, plumbing, installing pavers outside and pouring concrete driveway, installing a wheelchair lift, and more. They handled unexpected setbacks well, communicated effectively during the project, and finished the project on-time and on-budget. I would definitely hire them again, and recommend them to anyone doing a home renovation or addition."

"Francisco, Honika and the HomeBreakthorugh team always do a wonderful job in coming up with ideas and designs that we wouldn't think of, and which often will save us money. They are also very responsive to requests, questions, and concerns. We are very happy with our basement. Home Breakthrough has also done a bathroom and a kitchen reno for us as well. Very good work, and reasonably priced."

FAQs for basement remodeling projects in Bethesda, 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.
