"Mr. Riaz and his certified team provided great value over our entire experience with them. We recently renovated our condo and they did an outstanding job! Mr. Riaz and his team were very easy and pleasant to work with; he personally designed and gave various options with our ideas in revamping our home. Lonestar Contractors completed an entire renovation of our condo, specifically our kitchen which included new flooring, backsplash, custom work for newer technologies, cabinets, and granite countertops. Throughout the renovation, Mr. Riaz was always accessible and is very knowledgeable with our many questions and provided prompt responses. Him and his team were very professional and delivered on all agreed work within the scheduled timeline. Overall, I would highly recommend using them if you want top professional services with honest pricing and top quality work!"

They communicated everything clearly and the additional costs were handled separately and transparently. They also cleaned up after the work was done. I would hire them again."

FAQs for basement remodeling projects in Ashburn, VA
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.
