Extreme Seal Coating & Paving

I'm very disappointed in how everything went. When they showed up, I talked to the owners son who was there to supervise the workers. I pointed to a section that needed a bit of filler and he told me he would fix it if I gave him a nice tip. That's incredibly unprofessional; if that particular item wasn't included in the original agreement he should have just said so.
Part of a good sealing job is filling all cracks so water can't get in and freeze during the winter. Despite crack sealing being clearly listed on the agreement, none of the cracks were filled. I specifically asked the supervisor if he filled the cracks after they said they were done with the whole job and he assured me they did.
Once the driveway dried and I could inspect it, I was shocked at how only the most basic of sealing was done. I contacted Extreme and explained how I was very upset with the work. The owner claimed he would send someone out in 2 days but I got a text that day saying they might have to delay due to weather. Fine, I can wait. Now I've waited for a week and a half with near perfect weather and nothing has been fixed.
Given the service I received, I cannot recommend Extreme Seal Coating & Paving in any way.

I contracted Extreme Sealcoating to seal my residential driveway.  Had to pay in advance.  Company came to the house 2 hours late causing me to miss too much work.  Company did not complete job, stating they ran out of material, and would be back in an hour.  After 2 hours, I called and was told that everyone had gone home for the evening.  After a considerable number of calls over the next few weeks, Extreme Sealcoating stated they would be out again, and gave me a specific date and time.  I took off work to be there, but the company never showed up, and I could not get anyone on their phone.  This happened again 4 times over a period of 2 years.  Extreme Sealcoating never completed the job, refused to return my money.  They are an unethical company in my opinion.
Extreme Sealcoating has a written 2 year guarantee for all workkmanshipo and materials, but they do not live up to this guarantee.  Do not believe anything they tell you, and do not pay in advance of a complete job, if you do contract them.  
I ended up cpontracting with another driveway sealing company that did an excellent job.  
Do not use Extreme Sealcoating - this is my opinion from my experiences with them.

It went well. I wasn't there when the work was performed, but they communicated well and were knowledgeable.

Everytime we have called to get the payment that was due at time of service, Mr. Wanko lies by saying that he mailed it.  It has been very hard as we count on getting paid to put fuel in our semi.  When we get cheated, it makes it difficult to keep the truck running.
