"Five Stars. Background: we hired ARMS Home Improvement to completely remodel two bathrooms: Master and Hall (remove tub and create walk-in shower). Required plumbing, electrical, paint, framework, waterproofing, flooring, and problem-solving for issues that arose in both. Allen worked diligently and patiently with us to provide the bathrooms we designed and envisioned. Provided us with vendors. Worked with us on scheduling. Left the workspaces clean and tidy EVERY day. Gave us options on many decisions for component placement and honored our choices and explained why it would or wouldn't work. Allen respected our community surroundings (parking, trash, etc.) and integrated the work seamlessly into our daily lives. We felt the price paid for the scope of work delivered was of great value. We recommend ARMS Home Improvement very highly for virtually any home improvement project you want to do."

"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!!!"

"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."

"PI Kitchen and Bath finished our basement and completely transformed a space that we really were not getting much use out of before. We wanted the basement to feel like an actual extension of our home rather than just extra unfinished space, and that is exactly what we ended up with.The process involved a lot of different pieces, so having one team coordinate everything made it much easier for us. Communication was consistent, questions were answered along the way, and the crew did a great job with the details. We especially appreciated that they listened when we had questions or wanted to make adjustments rather than making us feel like we were slowing down the project.Now the basement is one of the most useful areas of our home. We are very pleased with the transformation and would recommend the PI Kitchen and Bath Frederick team."

"Basement Masters recently performed a remodel on our basement and did an excellent job. Our split foyer home had a basement that was in desperate need of modernization and we needed more space for our growing family. They gutted our entire basement including the bathroom to provide us with a beautiful new space that meets all our needs. From the start they were the clear contractor of choice. We solicited about three bids, including Basement Masters, for the work that needed to be done. Of the three, it was clear that Basement Masters knew basement remodels inside and out. Their pricing was easy to understand, clear, and quite honestly a better value than the other two contractor bids. Pavel, the owner, was very knowledgeable with our questions and gave advice where solicited. Throughout the bid and initial scoping process I always felt his and his team’s desire to be honest and provide the best service and value possible. It seems to me they operate off of pride of doing a great job and satisfying the customer and the fact that they are being paid to do it is just a benefit. The team started on time and were always professional and respectful of our home and time. I believe they even finished early. If there were any hiccups or questions the communication between myself and the project manager, Elena, or the construction team was always timely and all parties seeked to resolve the issue. I never felt we were being blamed or treated as if it was our problem and not theirs. And to clarify there were very little hiccups or issues. In fact we were blessed with a pretty smooth remodel. However, nothing is without a little bump or date push or whatever and anything like that was always handled well. It was our first major remodel and a significant amount of money to spend for us. We had huge concerns about the existing sump pump system and the Basement Masters team endured all our questions and concerns. They understood although it was common place to them, to us it was not. Again they always communicated and answered our questions around this issue. And I appreciate them putting us at ease as well as doing an outstanding job. In summary our basement has turned out beautifully. I honestly don’t think anyone could have done a better job and I would recommend Basement Masters 10 times out of 10 to any person looking for a contractor to remodel their basement. My only wish is they were the “masters” of everything, but I understand they are the Basement Masters because that is what they focus on and as such are able to really provide quality work and perform masterfully. Thanks again to Basement Masters."

FAQs for basement remodeling projects in Jefferson, 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.
