I called a few companies for a quote and realized that I should have gotten my porch reno (added interlocking stone) after I got posts installed. Most I contacted gave me quite high a price and said that newly installed stones will need to be removed so they could take the current posts out.
I eventually got in touch with Stefan who said that it wasn't a big deal and the quote he provided was very reasonable for the type of railing we choose. He showed us actual pictures of the railings which made choosing easier.
Installation was done within a few hours (2 week wait to have the railing manufactured). One thing that I highly appreciated was that there a minor chip that happened during the installation and I didn't notice it at all. Stefan pointed it out to me and said that he'll replace that entire piece the next day. The next morning it was already replaced when I stepped out to go to work!
I have had my neighbors come to me to ask who did the railings because they look great. I have already recommended Aztec Aluminum and Stefan to my neighbors and one of my neighbors recently hired Aztec aluminum for their railing. Highly recommended. Thanks Stefan!
