The company
Northeast Ohio's court builders, family owned since 1957.
Industrial Surface Sealer, Inc. builds, resurfaces and repairs tennis, pickleball and basketball courts for the cities, schools, colleges, clubs and homes of Northeast Ohio: more than 1,200 courts in the last thirty years, by our own count, as SportMaster's authorized installer and a member of the American Sports Builders Association. The sealcoating the company started with in 1957 is still done every season, by the same crews. The yard is at 4000 East 86th Street. The president still walks every site.
Seventy years, in four paragraphs
Courts are the business. Tennis courts for schools and colleges, park courts for cities, pickleball banks for everyone, basketball courts from the Flats to the suburbs: built from the stone up on asphalt or post-tensioned concrete, or brought back with crack repair, an acrylic resurfacer and two color coats. We learned the acrylic systems when they were new, joined the American Sports Builders Association, became SportMaster's authorized installer for the region, and had been building and resurfacing courts across Northeast Ohio for decades by the time SportMaster came to film our crew at Kent State. The Oberlin College complex, the Hudson and Strongsville banks and the Parma Heights rebuild are on the project pages with the rest.
Then pickleball happened. Now the calls are for dedicated pickleball courts and for tennis courts converted to them, from cities, park districts, schools, clubs and homeowner associations across the nine counties, and the courts at Hudson, Richfield, Strongsville and Parma Heights are the ones on the home page and the videos page. The surface is the same acrylic, the lines are still hand taped and hand painted, and the siting has a new word in it: noise.
The name says where we started: Industrial Surface Sealer, sealing the lots of the factories, churches and schools of Cleveland's east side at a time when every sealer was coal tar. Courts came because the same owners had courts, and the courts took over. Sealcoating, crack filling and striping are still done every season, about three million square feet a year, by the same crews with the same discipline: clean it, fill the cracks, two thin coats, lines, come back in three years. It is the second business now, and a good one.
What has not changed: one yard, a president who walks every site and writes every proposal, crews that do the whole job, and the knowledge of what a Northeast Ohio winter does to a surface that was rushed. Draft for Carl to correct: the family history, the names and the dates belong here.
The people
Who you will deal with.
A small company on purpose.
Carl J. Gedeon
President
Walks every site, writes every proposal, and has been building courts and sealing lots in Northeast Ohio for most of his life. The articles on this site are his. carl@industrialsurface.com

The crews
Base, coating, sealing, striping
The same people from the first lift of stone to the last line. Several have been with the company for decades and have resurfaced the same courts twice.
What we build with
The materials and the memberships.
SportMaster acrylic surfaces
Made by ThorWorks in Sandusky, Ohio, an hour west of the yard; 100 percent acrylic resurfacers and color coats with fade-resistant pigments, the system in every court photograph on this site. SportMaster filmed our crew on a Kent State job to show how it is applied.
membrane crack repair
A membrane system that bridges a crack instead of filling it, so the court surface above stays whole through the freeze-thaw cycles that reopen filled cracks. On every court we repair.
American Sports Builders Association
The trade association for court and field builders; its construction guidelines for asphalt courts are the ones in the resources section and the ones we build to.
Our own equipment
Sealer rigs, crack kettles, striping machines, squeegees and the hands that know how to pull them, lasers and levels for the plane, and the trucks to move stone. Nothing on a job is rented from someone who does not know the trade.

How we work
Four rules, kept since 1957.
The president walks every site
Carl Gedeon measures, maps the cracks and writes the proposal himself. The person who quotes the job is the person responsible for it; Bay Village's staff put it this way when they hired us again: "Carl Gedeon would be the point person on this project like the other jobs they've done for the city."
One crew, start to finish
The crew that prepares the base is the crew that coats it. Nobody hands a court to a subcontractor who has never seen it.
The weather decides the schedule
Coatings and sealers only work in warm, dry weather, so the calendar is the weather's. We tell you where your job sits in it and we do not start a coat we cannot finish.
The honest alternative is on the proposal
Repair now and resurface later, or the other way round; sealcoat or patch; asphalt or concrete. Both prices, both reasons, your choice.
Public work, the public way
Competitive bids above the threshold, quotes below it, and cooperative purchasing: we are SportMaster's authorized installer under the Equalis Group contract (COG-2138B), so a member city or school can buy court work at the contract's rates without running its own bid. Normal wage rates, bonded and insured, a two-year limited warranty on coatings and one year on asphalt, payment at the end of each stage.
The work
Three jobs that say what we do.
Parma Heights: three tennis and seven pickleball courts at Greenbrier Commons
A city's whole court complex rebuilt in one season, bought through the SportMaster cooperative contract without a separate bid. The biggest job on the public record.
The project
Strongsville: twelve pickleball courts, four tennis courts and a basketball court at the Town Center
A new park's courts and players waiting at the gate before the crew had loaded the truck.
The project
Richfield: six pickleball and three tennis courts behind the Village Hall
A village that built pickleball and tennis together, behind the hall, in one go.
