Subfloor Installation & Prep in Rapid City, SD

Our team conducts a thorough inspection using moisture meters and visual assessments to detect hidden damage such as rot, mold, or warping. Small areas with minor damage can often be repaired using patching or reinforcement methods. However, when damage is widespread or compromises structural integrity, we recommend a full replacement. This approach guarantees a safe and durable base, avoiding future costly issues.

We primarily use high-quality plywood or oriented strand board (OSB) panels that comply with or exceed industry standards. These materials are selected for their strength, moisture resistance, and compatibility with the flooring type being installed. For certain projects, especially where moisture is a concern, we may also use specialized underlayments or vapor barriers to protect your subfloor and flooring.

We are experienced working with both wood subfloors and concrete slabs. When installing over concrete, we add appropriate moisture barriers and underlayment materials to prevent moisture-related problems and ensure a stable base. This allows us to install a wide range of flooring types, including tile, engineered wood, and laminate, over concrete foundations safely and effectively.

The timeline varies depending on the size of the project and the condition of the existing subfloor. Simple repairs or preparations might take a day or two, while full subfloor replacements can take several days. We provide clear timelines during the consultation phase and always work efficiently to minimize disruption to your home and daily routine.

While subfloor preparation is an additional cost, it’s an essential investment in the longevity and performance of your floors. Proper prep helps avoid costly repairs, squeaks, or premature flooring failure down the line. It protects your overall flooring investment and ensures the final result is beautiful, stable, and long-lasting—saving you money and hassle in the future.
