Firstly, I paid the down payment in June of 2018, and the driveway got pave in June of 2019.
Secondly the down payment was more than $13,000, because the project is big. They promised that they got it done in 2018, but they couldn't.
Thirdly, they're not professional to do a large job. The leveling was very badly designed for the main part of driveway (similar to a parking lot) on the front of garages. This will cause a lot of issues during freezing winters.
Fourthly, the connection section between the public road and my private parking lot was paved without shoulder. The asphalt is about 3 inches higher than the road base on both sides. On some parts, the pavement didn't align with the existing driveway and go off the road. It created more than 20 cm drop from the edge of asphalt pavement.
At the last, Black Tar claimed all of these are normal, and they don't want to fix any.
