The owner is on the job

Diamond Epoxy is Mark Costello's company. Mark is on site for most jobs himself, so the person who talks through your floor is the person who makes sure it gets done right. This business is his life, and he treats every floor that way.

Built to last, and backed for 20 years

Every floor uses commercial grade materials, and our floor coatings are backed by a 20 year warranty. Commercial and industrial floors get 20 year industrial systems made for heavy use.

Most garages done in one day

A garage floor should not take over your week. Most of the garages we coat are finished in one day, so you are parking on a finished floor fast.
