Cornerstone Brickworks did excellent work on my Aunt's chimney.
They showed up on time.
They kept the work-site tidy and safe.
The masonry work was professional, clean and well done.
The chimney cap was a precise fit as were the covers for the flues.
My only criticism would be that the flues were not precisely itemized in the original quote for the work. I would recommend that Cornerstone include them in future in their standardized quotes in order to avoid misunderstanding.
Overall, a job very well done. I would highly recommend them.
