Why Transform Your Basement?

SeaTac basement wall framing starts at $6,000 🛠️

Upgrading your basement offers numerous benefits for your SeaTac home. Whether you aim to boost resale value or gain extra living space, a functional basement is always an advantage. RENOVA in SeaTac excels in basement renovations, often making it a smoother project compared to other home remodels. Complexities arise when adding a basement bathroom, requiring trenching and breaking through cement. However, our licensed plumbers handle permits and specialized equipment, making this manageable. Waterproofing and proper insulation are crucial for any basement. Adequate insulation and the installation of energy-efficient windows can prevent drafts, keeping your home warm in winter and cool in summer.

We offer more than just basic renovations; we provide services like basement finishing to add those final touches, making it cozy and inviting. You might consider installing an entertainment center for movie nights or hosting guests. Our services also include basement window and flooring installations to complete your space. If you're unsure where to start, our complimentary interior designer will guide you through selecting fixtures, colors, and finishes, bringing your vision to life. We ensure minimal disruption to your daily routine during the remodeling process.

SeaTac basement lighting installation starts at $3,000 💡

Basement remodeling presents unique challenges. At RENOVA SeaTac, we plan meticulously to avoid and address problems efficiently. Moisture control is a primary concern due to the basement's below-ground level, which can lead to dampness. A robust waterproofing solution, like Drylok, is essential. Increasing sunlight through our window installation service also helps reduce dampness. Poor natural lighting can be solved by installing larger windows, layered lighting with ambient, task, and accent lights, and using light colors and reflective surfaces to brighten the space. You can tailor your basement design to meet your specific needs and preferences.

If turning your basement into an entertainment hub, consider soundproofing. Effective noise reduction involves installing soundproof insulation in walls and ceilings, using insulated drywall, and adding acoustic panels. Carpeting also helps absorb sound. Sealing gaps around doors, windows, and utility areas with acoustic sealant or weatherstripping can prevent noise leakage. Renovating your basement will significantly enhance its appeal, making it a pleasant space for you to use frequently.
