"Had basement windows installed. Great job, explained everything. The windows were the original ones. They covered the floors and the basement steps, cleaned up everything afterwards."

"I reached out to this company for a sump pump upgrade and a cracked wall repair. The technician who did my install was very polite and informative. We've had several big storms since my installation was done and I'm happy to say my basement has remained totally dry. I'm very glad I chose this company, I would recommend them to anyone in need of help with their basement!"

"Highly recommend Top Remodeling for their outstanding GENERAL CONTRACTING services. I completely trusted them with my Bathroom remodel, and the results exceeded expectations. We needed a Home addition, and their team executed it flawlessly. I requested a Kitchen remodel, and the attention to detail was impeccable. Wonderful experience from start to finish!"

"AES Builder & Home Improvements Inc. was absolutely amazing to work with from start to finish! They remodeled our original kitchen, and the results are beyond beautiful. From our very first meeting to the day we spent picking out custom design materials, the entire process was organized, collaborative, and enjoyable. Their coordination and communication throughout the renovation were top-notch! Every contractor who came into our home was professional, respectful, and genuinely cared about their work. They answered all of our questions and kept us informed every step of the way, even when there were small delays. The quality of the craftsmanship truly shows, and our new custom kitchen makes me smile every single time I walk in to cook. We couldn?t be happier with how everything turned out. If you?re considering a remodel, I can?t recommend AES Builder & Home Improvements enough! Thank you to Stephen, Shawna and the entire AES team!"

"Jon and his team just completed my basement remodel which included digging out the foundation, installing a sump pump as well as all the work to convert it from a dark cave to a bright, beautiful home office and gym. Since the day they started Jon over communicated, made sure I understood every step and patiently answered my endless questions. He was onsite frequently to ensure things went well and made the process significantly less stressful. The end result surpassed all my expectations, I can’t recommend him and his team enough. Everyone from his office manager, to each crew member went above and beyond. Thank you all for a job well done!"

"I had a great experience working with Guillermo, the owner of D&V Remodelling, for remodelling the bathroom in my condo. He was very knowledgeable and gave me great advice, recommendations, and feedback on the project. When we had unexpected plumbing problems he worked with me to sort it out and still managed to finish the project just one day longer than the estimated timeframe for the project. I would happily work with him again on future projects."

FAQs for basement remodeling projects in Severn, 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.
