Ed is easy to deal with and honest. He provided me an estimate over the phone ... he asks you for the size of your garage (1- or 2-car) and if you have interlocking around the driveway. He was a little more expensive that the other 2 companies that I've spoken with, but I felt at ease with him. He was only $10 expensive anyway.
I asked him for the procedure and material they use. This is very important as I've seen other companies do it for my neighbours and sadly, the others do it cheaply and haphazardly.
Ed's 2 sons go onsite and do the job. They look like college guys, but don't be deceived, they are courteous and professional. Ed is very flexible with scheduling. I had to move my project because my landscaper had to do more work. On the day of the work, the boys arrived a bit early. Unfortunately, my interlocking stones were a little damp and they didn't want to continue unless it's dry (the tape won't stick). One of the boys said, "I don't want to risk it and ruin your new interlocking stones. We can come back and do it for you tomorrow." It's my fault because I watered a few hours earlier thinking it would eventually dry up. Anyway, I think that was a very good gesture. They were genuinely concerned.
I am so happy with their work. Modesty aside, I think I have the best looking driveway of all my neighbours who sealed this summer.
It's only been a couple of weeks. I am curious to see how this would look like in a few months. If it doesn't hold, I'll write an update here.
