Common Questions
Do you offer help with plumbing inspections for older homes in St. Louis?
Yes. Given the age of many homes in our area, our showroom specialists are well-versed in the common plumbing configurations found in St. Louis houses. While we don't perform on-site inspections, we provide detailed client prep worksheets to guide you through what to look for. We can then recommend the right replacement parts or upgrade options from our broad selection to address issues specific to older plumbing systems, helping you plan your project effectively.
I need to replace a sink. Can you help me choose one and get the right installation parts?
Absolutely. Sink installation and replacement is a core service we support. Our specialists will help you select a sink that fits your space, style, and budget from our extensive showroom collection. More importantly, we'll ensure you leave with all the necessary mounting hardware, faucets, drains, and supply lines specific to your new sink and existing St. Louis plumbing, preventing multiple trips to the store.
My basement flooded after heavy rain. What plumbing products do you carry to help prevent this?
Basement flooding is a common concern here. We stock a range of products to help mitigate water issues, including sump pumps, backup systems, specialty drain pipes, and waterproofing supplies for fixtures. Our team can discuss the different options based on your home's setup and help you gather the quality materials needed for a durable solution, whether you're making repairs or installing a new prevention system.
