Frequently Asked Questions

  • When should you consider whole-home repiping?

    Whole-home repiping is ideal for aging homes with frequent leaks, low water pressure, or discolored water. It's also recommended before major remodels to avoid disrupting new finishes. At Cervantes Construction, we recommend inspections before renovation projects to assess your plumbing system's condition.
  • What's the difference between tankless and standard water heaters?

    Tankless water heaters provide hot water on demand and are more energy-efficient, while standard tank systems store heated water for immediate use. Proper sizing based on household demand is critical for either option. Cervantes Construction helps San Jose homeowners choose systems that integrate seamlessly with existing plumbing.
  • How does copper repiping improve water quality?

    Copper repiping eliminates corrosion and buildup from aging pipes, improving water pressure, taste, and clarity. It's a durable, long-term solution that meets current code standards. At Cervantes Construction, we specialize in copper for its reliability and value in South Bay homes.
  • What affects the cost of a kitchen remodel with plumbing changes?

    Cost factors include layout changes, the number of fixtures, appliance upgrades, and water line rerouting. Moving sinks or adding islands increases complexity and labor. Cervantes Construction provides transparent pricing and manages both plumbing and construction to avoid surprises.
  • Can you add a bathroom during a home addition?

    Yes, adding a bathroom during a home addition requires new plumbing lines, drainage, and proper integration with existing systems. All work must meet local code for water and waste connections. Cervantes Construction coordinates plumbing, structural, and finish work from foundation to completion.
  • What's the biggest mistake homeowners make with repiping?

    Many homeowners delay repiping until after a remodel, which can damage new finishes and increase costs. Assessing plumbing before renovations prevents disruption and costly rework. At Cervantes Construction, we recommend thorough inspections before major projects to plan efficiently.
  • How do you size a tankless water heater for a household?

    Tankless water heater sizing depends on the number of fixtures, simultaneous usage, and flow rate requirements. Undersizing leads to insufficient hot water during peak demand. Cervantes Construction calculates proper sizing based on household needs and ensures safe gas and water connections.
  • Why is gas line work best done by experienced professionals?

    Gas line installation requires precise connections, code compliance, and safety testing to prevent leaks and hazards. Improper work can endanger occupants and fail inspections. Cervantes Construction brings 19+ years of experience handling gas lines for appliances, additions, and remodels in San Jose.
  • What plumbing upgrades work best in older San Jose homes?

    Older San Jose homes benefit from copper repiping, water heater replacements, and updated gas and water lines. These upgrades improve pressure, efficiency, and reliability while meeting current codes. Cervantes Construction specializes in modernizing aging systems without disrupting daily life.
  • How long does a full home repipe typically take?

    A whole-home repipe usually takes several days to a week, depending on home size and complexity. Work is organized to minimize disruption and maintain clean job sites. Cervantes Construction coordinates scheduling clearly and focuses on efficient, high-quality copper installations.
  • Do bathroom remodels require new plumbing if fixtures move?

    Yes, moving showers, tubs, or sinks requires rerouting water supply and drain lines, plus code-compliant venting. Structural access may also be needed. Cervantes Construction handles plumbing and structural changes together, ensuring water efficiency and long-term durability.
  • What should homeowners prepare before a kitchen plumbing upgrade?

    Clear countertops, remove items under sinks, and plan alternative cooking arrangements if water or gas will be shut off. Communicate layout preferences and appliance specs early. At Cervantes Construction, we provide clear timelines and coordinate plumbing with your kitchen remodel schedule.
