Customer Reviews
Thermoscape
Professional service, on time and effective. Always will recommend for their services. Complete mold restoration.
Comet Plumbing And Sewer
Comet plumbing did a excellent job at my home . A fair price, competent, knowledgeable, efficient , clean and professional! Thank you Andy, I will be calling you for future issues if needed.
We had a drain issue right around the holidays and Andrew fixed it that same day. He and his team have always done great work at a fair price!
Andrew from Comet Plumbing was wonderful! He helped install two clean-outs and fixed a root infested pipe for a reasonable price (plus nice discount). I'll definitely be using them again!
Consider Thermoscape if...
- ✓ You have confirmed mold growth requiring professional remediation rather than a plumbing leak causing moisture issues
- ✓ Your project involves mold restoration work where 28 years of specialized experience provides meaningful advantage in handling complex contamination scenarios
- ✓ You value a company with nearly three decades navigating evolving mold remediation standards and protocols
- ✓ Punctual, professional service delivery matters more to you than same-day emergency response for this type of scheduled remediation work
Consider Comet Plumbing And Sewer if...
- ✓ You need plumbing diagnostics, repairs, or installations—from quick fixes to complete system replacements—rather than mold remediation services
- ✓ Fast response is critical, particularly if you're dealing with a plumbing emergency that needs attention within hours or on weekends
- ✓ You want high owner involvement with Andrew Rhodes personally handling your project and providing detailed explanations of problems and solutions
- ✓ You value clear communication throughout the project, including camera inspections to identify underlying plumbing issues that might be causing moisture problems
Questions to Ask Before Hiring
- → If you have both water damage and mold, ask Thermoscape whether they identify and repair plumbing sources or only handle remediation after plumbing is fixed
- → Ask Comet whether they coordinate with mold remediation contractors if plumbing repairs reveal contamination requiring specialized cleanup
- → Confirm with each company whether your specific problem falls within their service scope, particularly if you're uncertain whether you need plumbing repair or mold remediation
- → Ask both contractors to inspect your situation and explain whether the issue requires plumbing work, mold remediation, or both in sequence
The Bottom Line
This comparison only makes sense if you have both plumbing and mold issues requiring separate specialists. For plumbing problems—leaks, replacements, drain issues—Comet Plumbing is the clear choice with 15 years of focused plumbing experience, same-day response, and high owner involvement. For mold remediation after moisture sources are controlled, Thermoscape brings 28 years of specialized experience in that distinct field. If you're uncertain which problem you have, start with Comet for plumbing diagnostics since water intrusion must be stopped before effective remediation can occur. Don't hire a mold company for plumbing work or vice versa.

Frequently Asked Questions
These are separate trades requiring different licenses. If you have a plumbing leak causing mold growth, you'll typically need Comet to fix the water source first, then Thermoscape to handle mold remediation. Ask each company directly whether they coordinate with the other trade or provide referrals to ensure proper sequencing of work.
For mold remediation specifically, yes—28 years means Thermoscape has worked through multiple generations of remediation protocols and likely encountered more complex scenarios. However, if your primary issue is a plumbing failure causing moisture, Comet's 15 years of plumbing expertise is more directly relevant to preventing recurrence.
Call Comet first to diagnose and repair the plumbing source of moisture. Continuing mold remediation without fixing the water source is ineffective and wasteful. Once the plumbing is repaired and dried, then contact Thermoscape for proper mold assessment and remediation if needed.
You may be unsure whether your problem is active plumbing failure or resulting mold contamination, or you need both services and want fully licensed, insured contractors for each. These companies serve sequential needs in water damage situations rather than competing for the same work.

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.
