Here's How We Handle Your Project

We start with an honest assessment of what you’re working with. Every basement is different, and yours might have moisture issues, structural concerns, or layout challenges that need addressing before we can make it beautiful. We’ll tell you what needs to happen and why.

Next comes the planning phase where we work out the details that matter – electrical placement, flooring selection, insulation requirements, and how to handle any moisture control. This isn’t where we upsell you on things you don’t need. It’s where we make sure the finished space actually works for how you want to use it.

Then we get to work. We handle everything from permits to cleanup, keeping you informed about progress and any issues that come up. When we’re done, you get a finished basement that feels like it was always part of your home, backed by our warranty and built to last in Pacific Northwest conditions.

What's Included in Your Basement Renovation

Your basement remodeling project covers everything needed to transform the space properly. We handle moisture control and waterproofing because that’s non-negotiable in our climate. Proper insulation and drywall installation. Electrical work that gives you adequate lighting and outlets where you need them.

Flooring is a big decision for basements, and we’ll walk you through options that actually work below grade – luxury vinyl plank, engineered hardwood, or polished concrete, depending on your space and budget. We can install drop ceilings or drywall ceilings based on your access needs and height requirements.

If your basement renovation includes a bathroom, wet bar, or kitchenette, we handle the plumbing integration too. The goal is a finished space that functions like any other room in your house, not a basement that feels like a basement. Every project comes with our warranty because we’re confident in the work we do.

How long does a typical basement remodeling project take in Hollywood, WA?

Most basement finishing projects take 3-6 weeks depending on the size and complexity of your space. Simple finishing work on a dry, structurally sound basement moves faster than projects requiring moisture remediation, extensive electrical work, or plumbing additions. We’ll give you a realistic timeline during your consultation based on what your specific basement needs. Weather doesn’t typically impact basement work the way it affects exterior projects, so we can work year-round. The key factors that affect timing are permit approval, material delivery, and any unexpected issues we discover once we open up walls or flooring.

What basement flooring options work best in the Pacific Northwest climate?

Luxury vinyl plank is often the best choice for finished basements in our area because it handles moisture well and feels comfortable underfoot. Engineered hardwood can work if moisture control is excellent, but solid hardwood is risky below grade. Polished concrete is durable and moisture-resistant but can feel cold. Carpet is possible in truly dry basements but requires careful moisture management. The right choice depends on your basement’s moisture history, your budget, and how you plan to use the space. We’ll test moisture levels and recommend flooring that makes sense for your specific situation rather than pushing the most expensive option.

How do you handle moisture control during basement renovation?

Moisture control starts with identifying where water is coming from – whether that’s condensation, minor seepage, or actual leaks that need fixing first. We install proper vapor barriers, ensure adequate ventilation, and use moisture-resistant materials throughout the project. This might include waterproof drywall in areas prone to humidity, proper insulation that won’t trap moisture, and flooring materials that can handle occasional dampness. We also make sure your basement has adequate dehumidification and air circulation. Skipping moisture control to save money upfront leads to mold, damaged materials, and expensive repairs later. We’d rather do it right the first time.

Do I need permits for basement remodeling in Hollywood, WA?

Most basement finishing work requires permits, especially if you’re adding electrical outlets, lighting, or plumbing. Even basic finishing work often needs permits to ensure everything meets current building codes. We handle the permit application process because we know what local inspectors look for and how to get approvals efficiently. Trying to skip permits might save money upfront, but it creates problems when you sell your home or file insurance claims. Plus, unpermitted work often doesn’t meet safety codes, which puts your family at risk. The permit process also ensures your finished basement adds legitimate value to your home rather than being considered unpermitted square footage.

What's the typical cost range for basement remodeling in Hollywood?

Basement finishing typically runs $25-60 per square foot depending on finishes, complexity, and what your space needs before we can start the cosmetic work. A basic 800 square foot basement might cost $20,000-35,000 for standard finishes. Higher-end materials, bathroom additions, or extensive moisture remediation increase costs. The biggest variables are usually electrical work, plumbing additions, and dealing with moisture or structural issues. We provide detailed estimates that break down costs so you understand what you’re paying for. Military and first responder discounts are available. The investment typically returns 60-70% when you sell, plus you get years of enjoying the additional living space.

Can you add a bathroom during basement remodeling?

Adding a basement bathroom is definitely possible, but it depends on your existing plumbing setup and local code requirements. If your basement already has rough plumbing or is on a sewer system, installation is more straightforward. Homes with septic systems or basements below the main sewer line might need ejector pumps, which adds complexity and cost. We’ll assess your situation and let you know what’s involved before you commit to the project. A basement bathroom significantly increases the functionality of the space, especially if you’re creating a guest suite, home office, or entertainment area. We handle all the plumbing, electrical, and ventilation requirements to ensure your new bathroom meets code and functions properly.
