Situation

DIY Fix Options

Call a Plumber If…

Slow draining water Boiling water, baking soda + vinegar, plunger Problem returns quickly or gets worse
Standing water Remove plug, pull out hair/scum, plunge Water doesn’t shift after several tries
Hair/soap build-up in P-trap Unscrew, clean, and reconnect P-trap is cracked or badly corroded
Deep blockage in pipes Use a drain snake or wire hook DIY methods don’t reach or clear the clog
Persistent foul smell Baking soda + vinegar rinse Smell continues, may indicate deeper drain issue

HomeService.Insure Safety Disclaimer

At HomeService.Insure, we encourage safe and sensible DIY, but your safety always comes first.

  • Only attempt basic checks and fixes if you feel confident.
  • Stop immediately if you notice burning smells, scorch marks, leaks, or anything that looks unsafe.
  • Never attempt electrical or gas repairs beyond simple resets or checks.
  • For complex, repeated, or potentially dangerous problems, always call a qualified Gas Safe engineer (for heating) or a certified electrician (for electrics).

By following this guidance, you reduce risks — but professional help should always be your first choice if there’s any doubt.
