Your basement is one of the largest untapped spaces in your home. Cascade Pro, Inc transforms unfinished and outdated basements throughout Tacoma and Pierce County into beautiful, functional living areas — from family rooms and home offices to fully permitted ADU apartments.
We handle every phase of the project: waterproofing, structural work, framing, electrical, plumbing, HVAC, finishes, and final inspection.
Every basement project is different. Here are the most common types of basement remodels we do:
Transforming a completely unfinished basement into a livable space with framing, insulation, drywall, flooring, lighting, and climate control. This is the most common project — turning wasted space into a family room, recreation area, or extra bedrooms.
Converting your basement into a fully permitted accessory dwelling unit with its own kitchen, bathroom, bedroom, living area, and separate entrance. This is a high-value project for homeowners looking to generate rental income or house family members independently.
Renovating a previously finished basement that’s outdated, water-damaged, or poorly done. We gut the old work and rebuild with modern materials, proper moisture control, and updated mechanical systems.
Finishing a portion of your basement while leaving the rest for storage, mechanical equipment, or future work. This lets you add living space on a smaller budget while keeping flexibility.
Every basement remodeling project follows a structured process to keep timelines tight and surprises to a minimum:
Basement remodeling is one of the highest-ROI home improvements you can make — it adds livable square footage without expanding your home’s footprint. Tacoma’s building codes have become increasingly ADU-friendly, and the city’s strong rental market makes property improvements a smart investment. As your local general contractor based right here in Tacoma, we know the permitting process inside and out.
Basement remodeling costs in Tacoma depend heavily on the current condition of the space, the scope of work, and the finishes you choose. A basic finishing project costs less than a full ADU conversion with plumbing and a kitchen.
Key factors that influence your project budget:
We provide detailed estimates after our basement evaluation so you understand the full scope and cost before any work begins. No surprises.
Yes. Finishing a basement into livable space requires building permits for framing, electrical, plumbing, and mechanical work. If you’re creating a separate dwelling unit (ADU), additional requirements apply. We handle the full permitting process.
Moisture is the most common concern with Pacific Northwest basements. We assess your basement’s current moisture levels and drainage conditions before starting any work. Depending on what we find, we may recommend interior drainage systems, vapor barriers, waterproof coatings, or exterior drainage improvements before finishing the space.
Most basement remodels take 2 to 5 months depending on scope. A basic finishing project is on the shorter end; a full ADU conversion with plumbing, kitchen, egress windows, and separate entrance takes longer. We’ll give you a realistic timeline during our initial assessment.
Building code typically requires a minimum finished ceiling height of around 7 feet for habitable rooms. We’ll measure your basement during our evaluation. If ceiling height is tight, there are sometimes options like lowering the floor (underpinning) or adjusting mechanical routing to gain the clearance needed.
In many cases, yes. Basement ADUs are increasingly permitted in the Puget Sound region. The unit needs to meet specific requirements for egress, ceiling height, ventilation, separate entrance, kitchen, and bathroom. We’ll tell you exactly what’s required for your property during our consultation.
Yes. Moisture control is a critical first step in any basement project. We evaluate and address moisture issues before any finishing work begins to protect your investment for the long term.
Stop wasting the biggest unused room in your house. Cascade Pro, Inc transforms basements throughout Tacoma into finished living spaces, rental apartments, and everything in between. We handle the entire process from evaluation to final inspection.
