Why Contractor-Supplied Equipment May Cost More Than Store Pricing
When a contractor supplies equipment, the installed price may include more than the retail shelf price because the contractor is also handling procurement, transportation, installation materials, and business overhead associated with providing the product. This typically covers product sourcing, ordering, pickup or delivery, handling, time spent obtaining materials, returns or exchanges when necessary, and warranty administration where applicable.
Before Calling a Plumber…
A few safe, simple checks may save you a service call:
- ✓If your current disposal jams frequently or is very loud, upgrading to a higher HP unit can solve both issues
Garbage disposals typically last 8–12 years in Knoxville homes. Hard water and heavy use accelerate wear. When replacing, a higher horsepower unit handles more waste and jams less — worth considering for larger households.
