Cascade Pro Inc is a full-service basement remodeling contractor serving Tacoma, Seattle, and communities across Pierce County and King County. With over 15 years of experience in residential construction, we convert unfinished and outdated basements into functional living spaces that add real value to your home. Whether you need a basement apartment, a home office, an entertainment room, or a legal ADU, our team handles every step from design through final inspection.
The most common basement remodel in the Tacoma and Seattle area converts raw or unfinished space into a comfortable living area. This can include a family room, recreation room, or media lounge. We handle framing, insulation, drywall, flooring, electrical, and plumbing to bring your basement up to the same standard as the rest of your home.
A basement ADU (accessory dwelling unit) is one of the most cost-effective ways to generate rental income from your existing property. Washington state legislation has made it easier than ever to permit basement ADUs, and Cascade Pro Inc has the experience to navigate local codes in Tacoma, Seattle, Puyallup, Lakewood, and surrounding cities. A legal basement ADU typically includes a kitchen, bathroom, sleeping area, and a separate entrance.
Remote work is here to stay, and a dedicated basement office or creative studio gives you the separation you need without leaving your property. We design quiet, well-lit workspaces with proper ventilation, soundproofing, and wiring for high-speed internet.
Basements are ideal for home theaters, game rooms, bars, and fitness areas. The below-grade location provides natural sound dampening, and the open floor plans common in basements give you room to work with.
Cascade Pro Inc manages your entire basement remodel from start to finish. Our process includes:
Design & Planning — We evaluate your existing basement layout, ceiling height, egress requirements, and structural conditions. Our team works with you to develop a floor plan that maximizes square footage and meets your goals, whether that is a single open-concept room or a multi-room layout with a bathroom and kitchenette.
Permits & Code Compliance — Basement remodels in Washington state require permits for structural changes, electrical, plumbing, and HVAC work. If you are building a basement ADU, there are additional requirements for egress windows, ceiling height minimums, and separate utility metering. Cascade Pro Inc handles all permit applications and coordinates inspections with local building departments in Tacoma, Seattle, and surrounding jurisdictions.
Construction & Finishing — Our crews handle framing, insulation, vapor barriers, drywall, flooring, trim, paint, and all finish work. We coordinate licensed subcontractors for electrical, plumbing, and HVAC so you have one point of contact throughout the project.
A finished basement is one of the highest-ROI home improvements you can make in the Pacific Northwest housing market. Here is what a basement remodel can do for your property:
Increase usable square footage — Most Tacoma and Seattle homes have significant unfinished basement space. Finishing that space effectively adds another floor to your home at a fraction of the cost of building an addition.
Generate rental income — A basement ADU or rental suite can produce steady monthly income in the strong Tacoma and Seattle rental markets. This is an increasingly popular option as housing demand continues to grow across the Puget Sound region.
Boost property value — A professionally finished basement adds real value to your home. Buyers in this market are willing to pay a premium for a home with finished, usable lower-level space—especially if it includes a legal rental unit.
Solve space problems without moving — Whether you need a home office, a guest suite, a rec room, a gym, or a space for aging parents or adult children, your basement can provide the extra room you need without the cost and stress of relocating.
Basement remodeling costs vary depending on the scope of work, the condition of your existing basement, and the finishes you choose. Every basement is different, and the best way to get an accurate number is through a free on-site consultation.
Basic basement finish — Framing, drywall, flooring, paint, and lighting to create a clean, usable living area. This is the most affordable option and works well for family rooms, playrooms, or home offices.
Mid-range remodel — Adds features like a bathroom, wet bar or kitchenette, quality flooring, and upgraded finishes. This level of renovation turns your basement into a true living space with more functionality.
Full basement ADU conversion — A complete apartment with a separate entrance, full kitchen, bathroom, bedroom, and living area. This is the most involved option but also has the highest return potential through rental income.
Factors that affect your final cost include the size of the space, whether waterproofing or foundation work is needed, the extent of plumbing and electrical additions, and your choice of finishes. We provide detailed, transparent estimates before any work begins. Call us at (253) 338-1693 for your free estimate.

2. Design & Estimate — Our team develops a layout, selects materials, and provides a detailed written estimate with no hidden costs.
3. Permits — We prepare and submit all required permit applications and handle communication with the building department.
