Professional Basement Renovation Services

More Space, More Value, More Function

Your basement doesn’t have to be that place where you store holiday decorations and old furniture. When finished properly, it becomes the space your family gravitates toward.

Think about it: a comfortable family room where kids can play without waking the baby upstairs. A home office where you can actually focus. Maybe a guest suite that doesn’t feel like you’re sticking visitors in a dungeon.

The right basement renovation adds real square footage to your living space and genuine value to your home. But it only works when it’s done right the first time, with proper moisture control, insulation, and finishes that can handle the unique challenges basements present.

What's Included in Your Basement Project

Basement remodeling isn’t just about slapping up some drywall and calling it finished. We handle the full scope: moisture control, proper insulation, electrical work, flooring that can handle basement conditions, and finishes that look good and last.

In the Seattle area, moisture management is critical. We make sure your basement stays dry and comfortable year-round. That means proper vapor barriers, drainage considerations, and choosing materials that won’t warp, mold, or fail when humidity levels change.

We also understand that basement ceilings present unique challenges. Whether you need full drywall ceilings or prefer to keep access to utilities, we’ll design a solution that works for your space and your future maintenance needs.

How long does a typical basement remodeling project take to complete?

Most basement renovations take 3-6 weeks depending on the scope of work and size of the space. A basic finish with flooring, walls, and ceiling typically runs closer to 3-4 weeks. More complex projects with bathrooms, kitchens, or extensive electrical work can extend to 6-8 weeks. We give you a realistic timeline upfront and keep you updated if anything changes. Weather delays are rare since we’re working indoors, but permit approvals or material delivery issues can occasionally push schedules back.

What's the best flooring option for finished basements in this area?

In the Seattle area, we typically recommend luxury vinyl plank, polished concrete, or ceramic tile for basement floors. These materials handle moisture well and won’t buckle or warp if humidity levels fluctuate. Carpet can work in bedrooms or family areas if you have excellent moisture control, but we usually suggest area rugs over hard surfaces for comfort. Hardwood and laminate often have problems in basements due to moisture, even with proper preparation. We’ll assess your specific basement conditions and recommend what makes the most sense for your space and budget.

Do I need permits for basement remodeling in Pemrose?

Yes, most basement renovations require permits, especially if you’re adding electrical, plumbing, or changing the layout significantly. Even basic finishing work often needs permits to ensure everything meets current building codes. We handle the permit process for you, including applications, inspections, and making sure everything passes the first time. The permit costs are separate from our construction costs, but we include them in your project estimate so there are no surprises. Trying to skip permits might save money upfront, but it creates problems when you sell your home.

How do you prevent moisture problems in finished basements?

Moisture control starts with proper preparation before any finishing work begins. We check for existing water issues, ensure proper drainage around the foundation, and install vapor barriers where needed. We use moisture-resistant materials and leave appropriate gaps for expansion. Proper ventilation is also critical – we make sure air can circulate and humidity doesn’t build up. If your basement has had water problems in the past, we address those issues first before doing any cosmetic work. Rushing into finishes without solving moisture problems just creates expensive problems later.

What's a realistic budget range for basement remodeling?

Basic basement finishing typically runs $25-40 per square foot, while more complex renovations with bathrooms or kitchens can reach $60-80 per square foot or more. A 600 square foot basement might cost $15,000-25,000 for basic finishing, or $35,000-50,000 for a full renovation with multiple rooms and upgraded finishes. The wide range depends on your material choices, electrical needs, plumbing requirements, and how much prep work your basement needs. We provide detailed estimates after seeing your space, so you know exactly what you’re paying for.

Can you add a bathroom during the basement renovation?

Yes, we can add bathrooms to basement renovations, but it requires additional planning for plumbing and drainage. In many basements, we need to install a sewage ejector pump since the bathroom will be below the main sewer line. This adds to the cost and complexity, but it’s definitely doable. We also need to ensure proper ventilation to prevent moisture problems. Adding a bathroom typically adds 2-3 weeks to the project timeline and requires additional permits and inspections. We’ll assess your basement’s plumbing access and give you realistic options during the planning phase.
