Jose and his team provided excellent customer service from the beginning phase through final installation. I will be doing more renovations in my office and will definitely hire him again."

"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."

"It was a pleasure again working with Yosuary Diaz and his team on our unfinished basement renovation. We hired them before for whole house interior painting. I would definitely hire him again for other home renovations. Him and his crew are great and are very skilled at what they do. Diaz was not the cheapest, but also not the most expensive contractor, but overall, well worth it! We had our entire basement gutted out and rebuilt. Diaz and his team rebuilt everything from the sub-flooring, new walls, and plumbing...and other major infrastructure that is not always thought of. We love our new basement with a complete bathroom! We highly recommend Yosuary Diaz and his team if you have a major home project."

"My basement floor was previously engineered hardwood and was ruined from water damage. Ronal had the floor removed and replaced it with tile and new quarter round to finish it off. The project was difficult: Ronal had to coordinate with other contractors in the house and I wasn't on site for any of it. His work was amazing. It exceeded my expectations and they were so fast!"

"Hired to fix the major water leak on the basement. The leakage was severe and the project was big. LFC did a great job: responsible, considerate, well communicated. Tony even did extra mile to help me to deal with the insurance issues. Very much appreciated. All the work was done with good quality."

"I asked for a complete bathroom makeover and left the vision up to Mike — and I couldn’t be happier. From securing the foundation and properly waterproofing the space to the final finishing touches, everything was handled with professionalism and care. The black and white tile design is absolutely beautiful and timeless. The built-in bench and handheld shower add comfort and functionality, and I specifically requested a serene, open space without glass — which was executed perfectly. The entire project was completed with great communication, attention to detail, and at a reasonable cost. I absolutely love the finished product and highly recommend Mike, City Renovations & Remodeling, LLC"

"We hired Camilla to remodel a spare upstairs bedroom closet for a stacked washer/dryer. She estimated the project to last 7-10 days. She was able to get it done in 2 days! We had furniture to move and cover over three floors (basement to 2nd floor) in order to get the electrical and plumbing up to the closet, but being put out only 2 days for such extensive work is amazing! The workers were clean, efficient and courteous. Highly recommended."

FAQs for basement remodeling projects in Gaithersburg, 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.
