Your Questions, Answered Clearly


  • How much to replace a kitchen faucet?

    Pricing depends on the faucet type and installation complexity. We provide flat-rate pricing before starting, so there are no surprises.

  • Why is my toilet constantly running?

    A worn flapper, faulty fill valve, or improper adjustment often causes constant running. These issues are usually quick to fix with the right parts.

  • Can you install a new sink and hook up everything?

    Yes. We install new sinks, connect drain assemblies, water lines, and related components to ensure proper drainage and no leaks.

  • Is it worth fixing a leaky faucet or replacing it?

    If the fixture is in good shape, replacing cartridges or seals is often enough. If it’s outdated or heavily corroded, replacement may provide better long-term value.
