"We write this review as a sigh of relief now that our renovation project with River View is finally complete. The quality of the final work is excellent, and the construction crew, architect, and county inspector were all great to work with. The original crew we worked with, led by Edwin, were so hardworking, friendly, thorough, and fast. That's what really pushed us from 2 to 3 stars. However, the process getting here was frustrating and unnecessarily chaotic. Timeline & Communication Issues: Initial promise: We were clear that the renovation had to allow us to live in our home during construction and be completed before Christmas. Early communication: Our original project manager, Cris, was personable, and early communication seemed fine, if a bit informal and sometimes inappropriately personal. Major miscommunication: Near the holidays, we discovered that the plans submitted included cutting into the roof — something we explicitly said we didn’t want. This contradicted verbal assurances and caused major last-minute changes. Project Management Failures: Poor planning and oversight: Cris and the architect’s plan didn’t align with the construction work. We had to get involved directly with the county to fix errors. Paperwork errors: Incorrect submissions to the county added delays and confusion, which we had to monitor ourselves. Last-minute scramble: We were cleaning up dust on Christmas Eve due to these planning failures. Personnel Turnover & Lack of Handoff: Cris leaves the company: No proper handover to James, the new PM, who was unfamiliar with our project. Crew replaced: The original crew, who were great, were gone; new crew had no context or direction. James leaves: Another handoff with no context — the third PM had no idea about our project or its outstanding items. Escalation mishandled: When we raised our concerns with Kyle, the CEO, the response felt dismissive, with no accountability for the previous missteps. In summary, it's a beautiful end result... but we’re glad it’s over. The process left us frustrated, confused, and frankly, exhausted."

"I recently hired Solid Foundation Construction LLC to replace my carpet with vinyl flooring, and the results are absolutely perfect. I’m a very detail-oriented, high-maintenance client who is rarely fully satisfied — yet this project exceeded all my expectations. The quality of the work is outstanding. The crew worked incredibly hard from morning until evening, moved quickly without sacrificing precision, and delivered flawless results. My floors look stunning, and I truly couldn’t be happier. The owner is also a pleasure to work with — professional, responsive, and genuinely committed to making sure everything is done right. I would recommend Solid Foundation Construction to absolutely anyone looking to improve their home. Do not hesitate to hire them. I already can’t wait to work with them again on my next project!"

FAQs for basement remodeling projects in Windsor Mill, 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.
