Hello Everyone,

And thanks in Advance for your advice, I recently purchased a 50's ranch style home. The driveway was in bad shape, cracked and peeling concrete two lanes wide and about 30 feet long. I hired a company to blacktop the driveway, The company cleaned up the concrete and layed aspahlt over the concrete. The black top looks good but here is my question.The company did not seal the driveway, Should I have the driveway sealed now? and if i should should i buy a commercial product or have a company do it? My attempts to research this have only confused me

Sorry even further, but in my opinion the asphalt should have never been placed over the concrete.

Asphalt is most properly installed by removing concrete, installing a reauired layer of stone, sub-base and then your final coating(s) of asphalt.

Installing asphalt over concrete only creates additional problems of cracking where concrete joints exist.

Sealing the asphalt is the least of your worries at this point.

Asphalt can be laid over existing concrete provided proper preparation is done. The contractor probably place a layer of oil or tar to make the two layers adhere. It will be fine, don't worry about it.

Sealing should be done this fall before wet cold weather hits. The asphalt needs to cure before being sealed. 3 to 6 months will allow the asphalt to fully cure and will allow the sealer to penetrate. Most driveway sealers include this advice. It would not be good practice to seal a freshly laid asphalt drive at the time of installation. Your contractor can advise you of his recommendations, and probably offers the service.
