5 Signs You Need Plumbing Repairs

Even small plumbing issues can create a huge problem. Knowing immediately that you need plumbing repairs can help save your time, money, and property. Here are five signs it’s time to call a professional plumber:

  1. Dripping faucets: A dripping faucet wastes water and increases utility bills. It can mean you have worn-out components.
  2. Slow drains: Clogs don’t have to create a complete blockage. If water takes longer than usual to drain, it’s often from a clog caused by grease, soap buildup, or debris.
  3. Low water pressure: Sudden, lower water pressure could mean there’s a hidden leak or buildup in your pipes.
  4. Unusual noises: Gurgling drains or banging pipes could be trapped air, blockages, or loose connections.
  5. Water stains or wet spots: Damp areas on walls or ceilings are signs of a hidden leak.

If you’ve noticed any of these issues, don’t wait. Professional repairs can prevent bigger problems later.

Garrett and Stephen came out and quickly and professionally replaced our 70-year-old sewer plumbing after it cracked. They worked super hard and ensured we had working plumbing each night and through the weekend. They finished and cleaned up and I would highly recommend them.

Chris was a very professional, knowledgeable, polite and patient plumber. They said he'd be here within the hour, he was here in 20 minutes.

Once we had all the parts, he installed it…
