About Blackfish Sealcoating

We are a small family based company that pays strict attention to detail. We treat every customer as if we were them. Every job is tailored to meet the specific needs of that customer. We have the equipment to properly complete the job without any hassles or unexpected problems.

We use hot pour crack filling instead of cold which fills the cracks better and lessens the chance of water damage to the pavement. Our sealer is better because we are still using coat tar emulsion and the competition is often using asphalt emulsion. Asphalt emulsion is not recommended for our climate because of premature wear. 

We are able to apply the sealer by squeegee machine to provide the best protection. We offer a spray application to help those customers with a strict budget. We are also a member of the Better Business Bureau in west central Ohio. We are fully insured and have professional, knowledgeable employees to answer any questions or concerns that may arise.
