What Our Clients Say
"Construction process was smooth, much quicker than anticipated, and the crew was extremely skillful with expertise in all aspects of the work—carpentry, plumbing, electrical, and tile. We are extremely happy with the end result—the kitchen is bright and feels bigger than we had anticipated."
"When Talha came over for his initial meeting, he didn't immediately ask about our budget like everyone else. He just listened to what we wanted. The renderings he created were so accurate—what we saw in the pictures is exactly what we got. Every single day when we walk into this kitchen, we smile."
"What stood out about Boss Design was that they weren't just contractors—they were designers first. The kitchen they created for us is exactly what we wanted, with plenty of cabinet space and better flow than we thought possible. They finished on time and on budget. Having one company handle everything made such a difference."

Frequently Asked Questions
A full basement remodel averages around $150,000 in our market. Adding a full bathroom brings the typical investment to approximately $180,000. Your specific cost depends on the size of your basement, whether you’re adding plumbing, and the finishes you select. During our free cost appraisal, we’ll discuss your vision and budget to give you a realistic number before you commit to anything.
On average, homeowners recoup about 70 cents for every dollar spent on basement finishing when they sell. That’s a solid financial return. But the real value is the years you spend enjoying that space, whether it’s a home theater, guest suite, or dedicated office. We encourage clients to finish their basements sooner rather than later to maximize that enjoyment.
Yes. We obtain and manage all necessary permits: building, electrical, plumbing, whatever your project requires. You don’t need to visit any permit offices or coordinate with inspectors. We handle applications, fees, and scheduling inspections. That’s part of our design-build service, and it’s one less thing for you to manage.
Absolutely. Basement bathrooms are one of the most popular additions because they make the space truly functional as a guest suite or independent living area. We handle all the plumbing rough-in required for toilets, sinks, and showers. Adding a full bathroom typically brings the project investment to around $180,000.
Proper moisture management is essential for any basement project. We assess your current conditions, install appropriate barriers and drainage systems, select moisture-resistant materials, and ensure adequate ventilation. If there are existing water issues, we address them before finishing work begins.
Timeline varies based on scope. The design phase typically takes 1-2 months, followed by 4-6 weeks for permitting and scheduling. Construction duration depends on the size of your basement and complexity of the project. During your consultation, we’ll provide a specific timeline for your situation.
Yes. That’s the point of our fixed-rate contracts. During the design phase, you select every material: flooring, lighting, fixtures, paint colors. Because every detail is decided upfront, we can give you an exact price. No allowances that turn into overages later.
Common uses include home theaters, guest suites, home offices, recreation rooms, fitness spaces, and entertainment areas with bars. Many clients combine multiple functions in one space. We design based on how your family will actually use the space, not generic layouts pulled from a catalog.
