A number of years ago we had A1 pour a sidewalk from the front of our home to the rear walkout patio. At about one year, the sidewalk pulled off of the house from a centimeter to about an inch and a half the entire way. I called A1 who sent out three different representatives who said that was normal. After inspecting a number of other sidewalks I recognized that this space was not normal in my opinion. After agreeing to come seal the gap on three occasions they failed to show or complete the seal. Fast forward a few years when I was selling my house. I called the company on numerous occasions and left messages asking for help to seal the area as the new buyer placed a condition that this be completed before the sale. To this day, NOBODY has returned any of my messages. The reason that I am writing this review is that they are very friendly when they want to get paid; however, when it comes to helping afterwards they will not return phone calls. All I was asking for was the gap to be sealed. The funny part is that I would have gladly paid them for the job. Instead, I went to Northland Concrete and bought sealer and completed the job myself. I would carefully your options and the possible warranties on any concrete products that you purchase.
