Key Differences

The most meaningful difference between these contractors is Water Heaters Express's documented customer track record versus Complete Plumbing Works' limited feedback history. Water Heaters Express has established clear patterns of rapid response to emergencies, competitive pricing, and professional installation quality across tank and tankless systems. Their 18 years of licensed experience edges out Complete Plumbing Works' 16 years, but more importantly, they've focused that experience exclusively on water heater services, developing specialized expertise in emergency response and quick turnarround installations. Complete Plumbing Works offers broader plumbing capabilities beyond water heaters, which could matter if your project involves additional plumbing work, but without customer feedback to verify their service quality, responsiveness, or pricing, you're making a decision with less information. Both companies' lack of workers compensation creates identical liability concerns that you'll need to address regardless of which contractor you choose.

Consider Complete Plumbing Works if...

  • You need plumbing work beyond just water heater service, such as pipe repairs, drain issues, or fixture installation that could be bundled into one project
  • You're willing to conduct additional due diligence by requesting recent references and verifying their current service quality directly
  • Your project timeline is flexible and doesn't require the documented rapid response that emergency water heater situations often demand

Questions to Ask Before Hiring

  • Ask both companies to confirm their current workers compensation status and request a certificate of insurance; if neither carries it, consult your homeowner's insurance agent about liability coverage for contractor injuries on your property
  • Ask Complete Plumbing Works for references from recent projects similar to yours and contact them to verify service quality, responsiveness, and pricing
  • Ask Water Heaters Express whether your specific plumbing issue falls within their water heater specialty or if you'd be better served by a general plumber
  • Request detailed written estimates from both companies to compare pricing, scope of work, and timeline commitments

The Bottom Line

If your project involves water heater replacement, repair, or tankless installation, Water Heaters Express is the stronger choice based on their specialized focus, documented rapid response times, and consistent customer feedback about competitive pricing and professional work. Their 18 years of experience concentrated solely on water heaters provides exactly the expertise these projects require. Choose Complete Plumbing Works only if your project extends beyond water heaters into general plumbing work that justifies their broader capabilities, but request and verify recent references first. Regardless of which contractor you select, address the workers compensation gap immediately by contacting your homeowner's insurance agent about liability coverage before any work begins.

Frequently Asked Questions

For straightforward water heater replacement, Water Heaters Express's specialization offers advantages: 18 years focused exclusively on water heaters means they've handled more installations and can likely work faster. Their customer feedback confirms rapid response and competitive pricing. However, if your water heater issue might involve broader plumbing problems like main line issues or extensive repiping, Complete Plumbing Works' general capabilities could prevent you from needing a second contractor.

This is a legitimate concern that requires action on your part. If a worker is injured on your property and the contractor lacks workers comp, you could be held liable for medical expenses and lost wages. Before hiring either company, contact your homeowner's insurance agent to understand your coverage and consider requiring the contractor to add you as an additional insured on their general liability policy. Some homeowners choose to only work with contractors who carry workers comp to avoid this risk entirely.

The absence of documented customer feedback for Complete Plumbing Works doesn't necessarily indicate poor service, but it does mean you're making a decision with less information. They may serve primarily commercial clients, rely on repeat customers, or simply not actively collect reviews. Before hiring them, request and contact recent residential references directly to verify their current service quality and responsiveness.

The gap between 16 and 18 years is minimal when both are veteran contractors. What matters more is how they've applied that experience: Water Heaters Express has focused their 18 years on perfecting water heater services with documented rapid response capabilities, while Complete Plumbing Works has spread their 16 years across general plumbing. For water heater work specifically, the specialist's focused experience likely outweighs the small time difference.

How We Compare Contractors

License Verification

All license data is sourced from official California CSLB records and verified regularly.

Review Analysis

Customer reviews are aggregated from Google and analyzed to identify patterns in service quality.

Detailed Comparison

We analyze credentials, insurance, experience, and feedback to highlight meaningful differences.

Not all licensed contractors are created equal. While a valid license is the baseline requirement in California, contractors can vary significantly in experience, insurance coverage, and customer satisfaction.

  • Experience matters: A contractor with 15+ years of experience has likely encountered and solved problems that newer contractors haven't faced yet.
  • Workers' compensation protects you: If a contractor without workers' comp insurance has an employee injured on your property, you could be held liable.
  • Reviews reveal patterns: Individual reviews can be misleading, but patterns across many reviews often reveal a contractor's true strengths and weaknesses.
  • Bond amounts vary: A contractor's bond provides financial protection if they fail to complete work as agreed. Higher bonds offer more protection.

Taking time to compare contractors on these factors can save you from costly mistakes and help ensure your project is completed by a qualified professional.
