CrawlSpace-Seal Patented Wood Protection Sealer — 5 Gallon Orange Tint

Patented Crawlspace Protection. One Spray. Forever Dry.

The wood subfloor is what matters. Tarps fail. Dehumidifiers run up electric bills. CrawlSpace-Seal seals the wood itself—protecting against moisture, mold, and structural damage for 50+ years.

The Problem

Wet crawlspace wood creates a cascade of damage: mold, mildew, bouncy floors, sagging beams, cracked tile, hardware rust, and potential health issues for your family. Tarps tear. Dehumidifiers mask the problem without protecting the wood. By the time inspectors discover it, you're facing thousands in repairs and a major home value hit.

The Solution

Like shrink-wrap for every inch of your wood. The breathable, transparent orange-tinted seal allows proper moisture release while keeping water and mold out. Proven to dry subfloor moisture from 24% down to 8–10% MC—the structural safety level. One spray application. One day to complete. Water-based cleanup. No odor. No off-gassing.
