"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."

"I cannot give enough kudos to the Conrad Homes crew. Mike West, John and Brian did a thoroughly professional job finishing part of our unfinished basement. The work is well done and finished very nicely; they were efficient and friendly. Work included framing, drywall, trim, suspended ceiling and painting, plus installation of several electrical outlets and ceiling fixtures."

"I would absolutely recommend Best Homes LLC. Jonathan and Jeffrey did an excellent job on my basement remodel. I was on a time crunch to sell my house and urgently needed to remodel my basement by building a full kitchen with wet bar, installing wood floor and stairway, interior painting, and light fixture replacements. They promised to complete this in a month, but got it done in less than 30 days, all without sacrificing quality. It was so stunning, just one week after they finished, I got an offer on my home. I have never seen a group of people work in such a coordinated, efficient, and diligent manner. His separate teams for plumbing, electricity, carpentry, flooring, and cabinet and appliance installation were extremely punctual, professional, and dedicated, sometimes working well into the evening. They never missed a schedule. The quality of their work was supreme. All county inspections passed. Jonathan also went above and beyond to accommodate my change orders along the way, and turned out very nicely. Above all, their pricing was very reasonable and more competitive than most quotes I got. I want to say thank you to Jonathan and the team and wish Best Homes LLC continued success!!!"

"Jeff is my go-to guy now for any remodeling project. He completed a 1400 sq ft basement complete with a full bath. My favorite thing about working with Jeff was he truly listened to our goals and preferences. Any time steps in the projects did not meet our goals, he would communicate with us to make adjustments. This ensured that our basement was absolutely perfect when it was completed. Jeff was very aggressively good when it came to his pricing to ensure it was fair for both parties. He also allowed us to adjust pricing to buy our own materials that matched our design preferences."

"Wow! Not sure how to say it more...just wow! Edwin, Leo, and the Pena team are amazing. They painted the exterior and interior of my home. Took about 2-weeks which isn't bad for such a big job. They were pleasant, experienced, and went over and beyond my expectations. On the exterior of my home, they found rotten wood behind my chimney (which I never would have seen) and replaced the wood immediately. In the interior of my home, they moved heavy furniture to paint behind. Absolutely amazing! I chose wisely with Pena Brothers. I would hire them again without hesitation. I highly recommend Pena Brothers Construction. Thank you Edwin and team for a job well done. Extremely pleased with the outcome."

"From the start to finish, we were very pleased. When Custom Home Creations Partner Garrett arrived, we were impressed with his thorough assessment of what work was needed and what we wanted done. His proposal was right on point with what we expected. The construction team arrived on time, were professional and they efficiently completed the project within the time frame we were quoted. We now have a beautiful, safe and secure pressure-treated wood deck and stairs and we look forward to staining it in early Spring. Here's our "Before and After" photos! We would definitely hire and recommend Custom Home Creations for future projects!"

FAQs for basement remodeling projects in Knoxville, 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.
