Commercial Waterproofing Lake Mary FL

---

Commercial waterproofing costs typically range from $4 to $10 per square foot, depending on the method used and the complexity of the project. Below-grade foundation waterproofing usually costs more than exterior wall coatings because it requires excavation or interior drainage systems. Factors like building height, accessibility, existing damage, and the type of waterproofing membrane all affect pricing. Getting an on-site assessment is the most accurate way to estimate costs for your specific building.

Common warning signs include water stains on interior walls or ceilings, peeling paint, musty odors, visible mold growth, efflorescence (white mineral deposits on concrete), and dampness in basements or lower levels. You might also notice cracks in foundation walls, deteriorating mortar joints, or pooling water near the building after rain. Addressing these signs early prevents more extensive structural damage and costly repairs down the road.

Quality commercial waterproofing systems typically last 5 to 25 years, depending on the materials used and environmental exposure. Elastomeric coatings generally last 10 to 15 years, while sheet membrane systems can exceed 20 years when properly installed. Florida’s intense UV exposure, heavy rainfall, and humidity can shorten lifespan if inferior products are used. Regular inspections and maintenance, like resealing joints and addressing minor cracks, help extend the life of any waterproofing system.
