J & J Plumbing & Heating LLC.

Washington's workers'-comp classes for J & J cover plumbing with sewer pipe cleaning and HVAC-R installation, service and repair, which matches the two halves of the business name. The jobs that come up most are household ones: water heaters, toilets, sinks disconnected and reconnected, dishwashers and disposals hooked up. The firm also holds Washington's lead-safe renovation certification, relevant in older Spokane-area homes where painted surfaces get disturbed during pipe or duct work. The crew sits in the 11-to-20 band, and the state lists Thomas Collins as a principal since 2021 and Shirley Collins since 2023. This is a residential service shop that grows through referrals and repeat customers. It suits a homeowner in Spokane Valley, Liberty Lake or Spokane replacing an aging water heater, clearing a sewer line or swapping fixtures during a kitchen refresh. Large commercial HVAC jobs and whole-house re-pipes sit outside the work it's known for, so those projects are better matched to a firm built around new construction and rough-in. Before comparing plumbing or heating quotes, write down the specifics: the age, fuel type and capacity of the water heater or furnace, where it sits, and whether venting or gas lines need changing. For sewer problems, note the symptoms and any past cleanouts. Ask each contractor whether the quote includes the permit, haul-away of old equipment, and any drywall or flooring access. Bids written to the same scope are the only ones worth comparing side by side.
