Supreme Sealcoating Inc.

Supreme Sealcoating, Inc. is an owner-operated asphalt maintenance company based in Delray Beach, Florida, serving Broward and Palm Beach counties. Jim Williams founded it in 1987 and still works every job personally, and the company takes one project at a time so that scheduling holds, weather permitting.

Sealcoating is the main service. The company uses Star Seal products blended with sand and additives for a non-skid finish and longer life, applied by spray or brush from a rig whose pump handles heavy sand loads. Its standard is a two-coat spray application, which it presents honestly: it does not hide cracks, and while a heavy sand squeegee coat can fill them temporarily, the cracks return within a year or two, so most customers choose the more economical spray. Jobs range from ten-space lots to properties with a million square feet of pavement, and large sites such as shopping centers are done in sections so tenants stay open, with a 16-building condominium complex and a 50,000-square-foot lot completed in two 36-hour halves cited as examples.

Asphalt repair uses saw-cut removal and hot mix, as on a hotel lot in Delray Beach where clusters of potholes were cut out and replaced before coating. Striping covers stall lines, arrows, accessible spaces, fire lanes and no-parking areas, curbs and car stops using fast-drying acrylic traffic paint through a laser-guided striper, and the company also installs car stops, speed bumps and road signs.

Estimates are free, and the company's site notes it remains in operation as of 2023 with a portfolio of before-and-after photos going back to its first commercial jobs in the late 1980s.
