Contractor sells waterfront Key Biscayne house for $16M during slow season

Florida Surface Pro founder Douglas Secrest and his wife, Carmen D’Ambrosio, sold their waterfront Key Biscayne home for $15.7 million during South Florida’s slow season. 

Records show Secrest and D’Ambrosio sold the house at 1020 Mariner Drive to CBSB 0208 LLC, a Delaware entity. The true buyer is unknown.

Maureen Jauregui with Coldwell Banker Realty had the listing, and Kaylee Leon with Top Tier International Realty brought the buyer.

Secrest is the founder and owner of Florida Surfaces Pro, a Fort Lauderdale and Tampa-based exterior home detailing business with operations across much of the state. 

The couple bought the Key Biscayne house for $9 million in 2021, property records show. Built in 2013 on 0.3 acres, the 5,800-square-foot house has four bedrooms, five bathrooms, one half-bathroom, a pool and a dock, according to records. Miami architect Cesar Molina designed the home, and it was renovated in 2022, the listing shows. 

It hit the market for $20 million in August of last year, according to Realtor.com.

Key Biscayne has become a magnet for wealthy buyers in recent years, with many purchasing pricey teardowns in the island community. In May, medical device boss Gerald Slemko sold a waterfront teardown for $19.3 million. In March, the son of the late former Miami mayor Maurice A. Ferré sold a waterfront teardown for $16.5 million. The former CEO of Telemundo sold a waterfront home for $18 million in April.
