We are a locally owned and operated small business based in Columbia MD. We value honesty and integrity, and treat your home as if it were our own. Our services are customized to the individual project, and we pride ourselves on the quality of our work and commitment to outstanding results. We started our construction business in 2018 as a division of Restoration 1 of Columbia - College Park - Annapolis, a Water/Fire/Mold Damage Restoration franchise. We have been operating as Zahlis Renovations since selling the restoration business in 2022. We have completed hundreds of construction projects since 2018, ranging from major additions down to small remodels. We look forward to serving you with the same level of care and craftmanship from which we earned our 5-star reputation.

"Chris and his team did a fantastic job. What started as, what we thought was, a small project of repairing some water damage and replacing a sliding door turned into a much larger mold remediation and replacement of the entire ceiling in the room. Chris was thorough with his inspection to ensure no mold was left, and his team did great work. They were flexible with our schedule with a toddler, completed the work as quickly as they could, and left the room nicer and safer than it was before. We are so grateful to Chris and his team and would happily hire them again for any future work. "

Looking for a professional that will give you an honest price and the best craftsmanship around? Armour Construction is the company for you! Call us today, we look forward to speaking with you (301) 570-8041 or (410) 489-6004! (Please note that we only do complete remodels and not single item projects).

"I posted my urgent request for same day dry wall repair service on Angi and Armour was one of the first to respond. They confirmed availability and quoted a fair price. Their qualified drywall repair person (Luis) arrived in less than 2 hours, and he did the work efficiently and with excellent quality. He also demonstrated courteousness and respect for my home by covering all floor areas before starting work and cleaning up after himself when done. The drywall and painting work was done so professionally that you'd never know the wall was ever damaged (see sample before and after photo attached). Based on this experience, I would highly recommend Armour Construction."

FAQs for basement remodeling projects in Columbia, 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.
