## What to Know Before You Hire

Bathroom renos in St. Catharines split into two very different jobs. In the century homes downtown and around Yates Street, the work is as much surgery as renovation — galvanized supply lines that should be replaced to the stack, out-of-plumb walls, and floors that need structural attention before tile goes down. In the post-war bungalows of Grantham, Merritton and Western Hill, it’s the classic 4-piece refresh — and increasingly, a second bathroom added in the basement, where waterproofing and proper venting decide whether the addition is an asset or a liability.

Whatever the vintage, insist on a written scope for waterproofing behind the tile and ask how surprises are priced before demolition starts. The specialists below are listed on NRCH with reviews from local homeowners.
