Hello RD,
We were shocked by your review and we are sorry that you feel this way. The pictures of your project look beautiful! When we sent Bruce to inspect your original tree root concern, you did not make mention of any other concerns to him. You live in a neighbourhood made beautiful by an abundance of mature trees. It is simply not true that they can only cause cracking less than 5 feet away. In fact, tree roots extend 2-3 times the width of the dripline.
35 years ago, we developed our warranty using the Ontario Ministry of Consumer and Commercial Relations guidelines for residential paving. In their brochure "A Guide to Residential Driveway Paving", it states that a good contractor should offer a one year warranty and they state "Contractors cannot be held responsible for damage caused by such things as tree roots, oil or gas spillage, high heels, ladders, lawn chairs or bicycle kickstands."
Although your tree root issue is not covered by any industry warranty, as a gesture of goodwill we indeed offered to repair it for you. At the moment it is only a hairline crack and too small to treat but if it becomes larger we have already offered to repair it. It can be filled with a rubber crack filler if you prefer but we find it unsightly and the polysand is more discrete. We can use the crack filler if that is your choice.
You questioned our expertise on diagnosing tree-roots. We made you the offer of cutting out the area and excavating the base and subgrade to investigate and expose the root but clearly there would be a cost associated with it if tree roots are discovered. Tree roots are a very sensitive issue and if they are to be cut, an arborist report must be submitted to the City beforehand to ensure the health of the tree won't be affected.
With regards to your further concerns about the depth of base materials on your patio, you must have dug your fence posts prior to our team installing the stonework when the sub-base only was installed. The final bedding layers are installed along with the interlocking stone.
The stone on your contract for the window wells was chosen to match the step and it is a new linear stone design trend and not meant to curve.
We will call you and set up an appointment for you to address your further concerns with Bruce and you can discuss it with him.
