OUR BASEMENT REMODELING SERVICES IN BELLEVUE

Full Basement Finishing

We turn cold, unfinished basements into polished, livable environments. Our full basement finishing services include structural framing, insulation, drywall, recessed lighting, LVP or hardwood flooring, and heating upgrades.

Whether you want a playroom, guest suite, or casual hangout space, we design for beauty, durability, and seamless flow with the rest of your home. Every detail—from layout to final coat of paint—is crafted for comfort and performance.

Looking to add rental income or accommodate long-term guests? We design and build full ADUs in Bellevue basements with private entries, full kitchens, bathrooms, laundry hookups, and egress windows.

These code-compliant units are great for multigenerational families, college-aged kids, or Airbnb use. We manage the entire process—from zoning review to final inspection—so you can focus on how to use the space.

Turn your basement into an entertainment retreat. We build custom media rooms with soundproofed walls, smart lighting, built-in surround sound, and tiered seating.

Home Offices, Gyms & Studios

Basements offer ideal privacy and quiet for high-focus and high-energy activities. We create home offices with ergonomic layouts, charging stations, and acoustic treatment for remote work. Our gym builds feature rubber floors, mirrors, mounted TVs, and proper ventilation for high-performance fitness.

We also construct custom art, music, and hobby studios for Bellevue homeowners looking for a space to unwind or express themselves.

Basement Bathrooms & Utility Rooms

We upgrade laundry areas, utility rooms, and basement storage spaces with smart, long-lasting design. Our updates include energy-efficient washers and dryers, deep sinks, folding counters, ventilated shelving, and moisture-resistant cabinetry.

Whether you're looking for a better laundry workflow or a streamlined utility room with modern finishes, we bring order and durability to the most practical parts of your basement.
