Domco Plumbing
They say problems come in threes. Ours arrived two weeks ago: first, the kitchen faucet decided hot water was overrated. Next, the waste disposal unit gave up on life. And when I went to investigate, ...
Domco installed an auto water and gas shut off for us. Justice was quick to provide an estimate. He even checked to see if a more cost effective solution could be done for the gas shut off. When he c...

Consider Domco Plumbing if...
- ✓ You need emergency plumbing service or value same-day availability, especially during weekends and holidays when Domco's rapid response record is strongest
- ✓ Your property requires workers compensation coverage for liability protection, which Domco maintains on file
- ✓ Your project involves older infrastructure where Domco's 22 years of experience diagnosing hidden damage and complications provides greater confidence
- ✓ You're in Folsom specifically, where Domco has established its primary service focus and community relationships over two decades
Consider Serieux Plumbing if...
- ✓ You're comfortable verifying liability coverage details directly and confirming your homeowner's policy adequately protects you during contractor work
- ✓ Your project is a planned remodel or repiping job where Serieux's demonstrated strength in complex bathroom renovations and whole-house repiping aligns well
- ✓ You value a highly educational approach and want a contractor who prioritizes explaining systems and preventive maintenance strategies
- ✓ Scheduling predictability matters more than emergency availability, as Serieux earns consistent praise for punctuality and organized scheduling
Questions to Ask Before Hiring
- → For Serieux: Ask specifically about liability coverage and confirm whether your homeowner's insurance would be primary if a worker is injured on your property, then verify this with your insurance agent before signing a contract
- → For both: Request references from projects similar to yours in scope and complexity, particularly if your home is older or the project involves hidden conditions
- → For Serieux: Ask how long their current crew has been together and what experience level the technicians carry, given the company's 8-year history
The Bottom Line
For most homeowners, Domco Plumbing is the safer choice. The combination of workers compensation coverage and 22 years of experience provides substantially better protection and expertise, particularly for emergency situations or complex projects where hidden issues may emerge. Serieux offers solid work and an educational approach, but the lack of workers comp creates real liability exposure that most homeowners should avoid. If you're drawn to Serieux for a planned remodel, have your insurance agent confirm your coverage for contractor injuries in writing before proceeding. Otherwise, Domco's veteran status and complete insurance coverage make the decision straightforward.

Frequently Asked Questions
For simple replacements in accessible locations, both contractors should handle the work competently. The experience gap becomes more valuable when complications arise—corroded connections, code violations in existing installation, or venting issues that require problem-solving. Domco's 22 years means they've likely encountered and resolved nearly every complication multiple times.
If a worker is injured on your property and the contractor lacks workers compensation, your homeowner's insurance may become the primary coverage for medical bills and lost wages. This could result in claims against your policy, potential rate increases, and personal liability exposure depending on your coverage limits. Contact your insurance agent to understand your specific policy's protections before hiring any contractor without workers comp.
Customer feedback suggests Serieux does emphasize explaining systems and preventive maintenance more explicitly than Domco. If you want to understand your plumbing and prevent future issues through education, this appears to be a genuine strength. However, this benefit shouldn't outweigh the workers comp consideration unless you've confirmed adequate liability protection.
Both companies receive consistent feedback characterizing their pricing as fair and transparent. There's no indication in customer reviews that Domco charges premium rates for their emergency availability. Same-day service doesn't necessarily mean emergency pricing if it's part of their standard operating model.

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.
