Kathay Plumbing Supply Corp.

New York has 662 building supply store listings on this page, which is enough that scrolling top to bottom isn't the fastest way through it. Narrow by ZIP instead. Long Island City's 11101 carries 17 entries, the most of any ZIP here, followed by 11218 with 12 and 10309 with 11. A handful of others, including 10001, 10018, and 11230, sit around 10 each. Picking your neighborhood first, then working the list, beats reading straight through hundreds of records.

Most of these listings come with a phone number, 655 out of 662, so calling ahead to check stock or hours usually works. Fewer carry a working website, 566 of them, so don't count on finding one for every shop. Paid placements are labeled Sponsored, and none currently appear in this category, meaning the order here is unpromoted directory data, not a curated or bought ranking. If you manage one of these stores and the ZIP or phone number is off, you can claim the listing and correct it yourself, which keeps the record useful for the next person searching.
