What Insurers Review About Electrical and Plumbing Systems in Oshawa
These figures describe properties in the Oshawa quote set and do not produce automatic price changes.
Most homes in the Oshawa sample have copper wiring, breaker panels, and copper plumbing. For an older property, document updates, disclose original or mixed systems when requesting a quote, and ask whether the insurer requires an inspection or licensed-trade report.
| System | What We Saw in Oshawa Quotes | Why Insurers Ask |
|---|---|---|
| Electrical wiring | The wiring is approximately 99% copper, approximately 0% mixed material and approximately 1% aluminum. | If a home has aluminum wiring, a combination of electrical wiring or other older electrical systems, insurers could ask for more information or require an inspection. |
| Electrical panel | About 100% of the panels are breaker panels, while 0% are fuse panels. | Insurers may require an electrical inspection where properties contain fuse boxes or other out-dated electrical systems as there may be fewer insurers prepared to insure such properties. |
| Electrical service | Around 80% had 100-amp electrical service whereas 20% had 200-amp electrical service. | Insurers also consider whether the electrical service can adequately power the home and its appliances. |
| Plumbing | PEX, copper/ABS, and PVC account for a minority of the total. Copper makes up the greatest proportion at approximately 71%, followed by copper/PVC (16%). | The system’s material, physical condition, and age may increase its vulnerability. Older or mixed-material systems may face a greater risk of leaks. |
