I had my walkway done in 2011. That winter it heaved and the stones had to be releveled which Masella Inc. did In 2012.In 2012, the walkway did not heave but some of the stones sunk. I contacted Masella Inc about it but they never came even though I had a 2 year guarantee. I contacted them again in 2013. They said they would pass by and fix it but they never came. I contacted them again in 2014 and 2015 but to no satisfaction. I wish they would just pass by and look at the job on my walkway and admit that something went wrong.
