ALBERTO CONCRETE

They did paver stone installation and sealing of my home driveway and walkway. The process of installation and completion was quite good.  However,  about a year after the job was completed  stains started to appear in many areas  which, after researching the paverstone manufacturer installation instructions, are likely to be cutting residue fluid  dripping from stones that were cut on-site. The instructions specifically warn against not letting the residue fluid drip on the pavers since it is practically impossible to remove. These stains were presumably masked by the sealant applied, but were exposed as the sealant wore off. I I have contacted Alberto's concrete several times but there has been no action. More recently I am also noticing some pavers that have sunk in.

My experience with this company is that once the job is done you are on your own. They are not professional about warraranty support  and do not not take responsibility for workmanship issues.

The contractor has been cited and was also sued. He wouldn't return his phone calls that were made to him. He discolored my driveway and over sealed and would not fix it. Some of the other work he did was actually good, too.
