J & J Plumbing & Heating LLC.

The state insures J & J under workers'-comp classes for plumbing with sewer pipe cleaning and for HVAC installation, service and repair, which matches the services it lists. The crew falls in the 11-to-20 range. Washington records the business from 2021, and the state lists Thomas Collins as a principal since 2021 and Shirley Collins since 2023. On the Idaho side it holds a contractor registration with the Division of Occupational and Professional Licensing. Most of its work comes through referrals and repeat customers. This is a residential service outfit. It suits jobs like swapping out a tired water heater in an older house, clearing a sewer line, or hooking up a dishwasher and disposal during a kitchen update. The lead-safe certification matters for pre-1978 homes, where disturbing old paint around pipes or ductwork calls for it. Large commercial HVAC systems and whole-house re-pipes fall outside the repair, replacement and hookup work this business centers on. Spokane-area winters set the calendar for plumbing and heating. Furnace service and any HVAC replacement are best scheduled in late summer or early fall, before the first hard cold puts every heating contractor on emergency calls. Freeze-thaw cycles stress exposed supply lines and outdoor spigots, so disconnecting hoses and checking crawlspace pipes before November saves trouble. Sewer lines in older neighborhoods often draw tree roots that grow aggressively through the dry summers, which makes fall a sensible time for a cleaning. Water heaters work hardest in January, when incoming water is coldest, so an aging tank tends to fail then.
