Drive Way Sealer
 

A few questions:

1) What should this service cost per square foot, etc; My driveway is approximately 125 feet long with room to park 15 or so cars at the top.

2) Is there a difference between water based and oil sealers;

I received my first quote of $1,400 for "oil" based sealer. This quote seems through the roof.

I paid $0.10/sq ft for both water based and oil based. The oil based got into the minor cracks and survived much longer. Last oil based application was 2 years ago and stiil looks decent.

In the northeast, the average cost for driveway sealing is typically between $.10-$.16 per square foot. Anymore then that could mean that they might have to do something else to prep the driveway before sealing, i.e., pressure wash, fill large cracks, touch-up the sides, etc... or maybe you live a long distance from the sealing company.
If you have a 5000 square foot driveway, and it is ready to be sealed, then it shouldn't cost you anymore then $800 to have it done.

Good luck.

Thanks for the help Rusty and bclaker. I have about a 5700 square foot driveway. There is a rock wall that runs the length on one side and I have a brick paver apron so there is some detail work necessary. That being said, it seems to me $1,000 is the max these quotes should be coming in at. I'll keep you posted.

There is a guy that I've met that does a great job of filling cracks and sealing driveways. I do not know his name but maybe someone from Southdown can help you. He seals many of the association roads throughout Southdown and from the reports I've heard his work sealing driveways is great.
He uses oil based sealer of commercial grade not the stuff you buy in the 5 gallon pales.
Wish I had one of his cards.
Good luck.
