Exterior Waterproofing in Sarasota

Sarasota's Gulf Coast location creates demanding waterproofing conditions: direct salt spray from Gulf winds, 54+ inches of annual rainfall, high humidity year-round, and sandy soils with variable water tables. Properties on Longboat Key, Lido Key, Siesta Key, and along the Sarasota bayfront face accelerated deterioration from constant salt exposure. Proper waterproofing protects property values—especially important given Sarasota's premium real estate market.

FCS provides exterior waterproofing throughout Sarasota County including Downtown Sarasota, Longboat Key, Lido Key, St. Armands Circle, Bird Key, Siesta Key, Gulf Gate, Palmer Ranch, Lakewood Ranch, and University Park. We serve luxury condominiums, waterfront estates, commercial buildings, cultural facilities, and hospitality properties throughout the region.

Sarasota waterproofing costs vary by application: building envelope/wall waterproofing typically runs $5-$18/SF (luxury specifications increase costs), foundation waterproofing ranges from $8-$25/SF, parking deck waterproofing costs $15-$35/SF, and premium residential waterproofing for luxury properties costs $10-$30/SF. Barrier island properties require marine-grade systems. Complete condominium waterproofing projects range from $50,000 to several million dollars.

For Sarasota's barrier island properties (Longboat Key, Lido Key, Siesta Key), FCS specifies marine-grade systems: high-performance polyurethane membranes with enhanced salt resistance, crystalline waterproofing for concrete in brackish environments, traffic-bearing coatings with UV stabilizers, and specialized systems for elevated structures. All systems are selected for Gulf exposure with extended manufacturer warranties.

Yes, luxury condominium waterproofing is a specialty for FCS. Sarasota's downtown has experienced significant high-rise development, and these premium properties require correspondingly high-quality waterproofing. We work with condominium associations on building envelope restoration, balcony waterproofing, parking structure waterproofing, and common area protection. Our team coordinates with building management to minimize resident disruption.

Sarasota's sandy soils, particularly on the barrier islands, present unique challenges: rapid drainage but susceptibility to erosion, variable water tables influenced by tides and rainfall, and potential for saltwater intrusion. FCS designs foundation waterproofing systems specifically for these conditions, including proper drainage, marine-grade membranes, and protection against both freshwater and saltwater exposure.

Yes, FCS has experience waterproofing Sarasota's historic and architecturally significant buildings including properties in the Burns Court area and along Palm Avenue. We use sympathetic waterproofing approaches that protect historic materials while maintaining architectural integrity. This includes breathable systems for masonry, period-appropriate drainage solutions, and careful attention to visual aesthetics.

FCS provides a 10-year workmanship warranty on exterior waterproofing installations in Sarasota, backed by manufacturer material warranties of 10-20 years. Barrier island properties face accelerated exposure—we recommend annual inspections and offer maintenance programs. Our warranty covers both materials and labor for any leaks resulting from waterproofing system failure, with complete documentation for condominium association records.
