Questions to Ask Before Hiring
- → Ask Thermoscape directly: Do you perform electrical work, and if so, can you provide references from recent electrical projects similar to mine?
- → Ask Thermoscape what percentage of their business involves electrical services versus other specialties like mold remediation.
- → Ask Dollens Electric for references from projects matching your specific scope, whether it's panel upgrades, generator installation, or troubleshooting work.
- → If Thermoscape confirms they do electrical work, ask how many years their lead electrician has been performing electrical installations and what types of electrical projects they complete most frequently.
The Bottom Line
If you need electrical work, Dollens Electric is the clear choice based on available data. They're a proven electrical specialist with 20 years focused on the exact services you're likely hiring for, with customer feedback that specifically addresses their electrical knowledge, communication, and project execution. Thermoscape may be an excellent contractor, but their documented expertise is in mold restoration, not electrical work. Don't assume licensing alone equals electrical competency—you need confirmed specialization. Contact Dollens Electric for your electrical project. Only consider Thermoscape if you can confirm they actively perform electrical work and they provide verifiable references from recent electrical projects similar to yours.

Frequently Asked Questions
Not necessarily. More licensing years only matter if they're spent doing the type of work you need. Dollens Electric's 20 years are clearly spent on electrical projects with documented expertise across the full range of residential electrical work. Thermoscape's additional 8 years may involve different specialties. Experience depth in your specific project type matters more than total licensing duration in unrelated fields.
Contractors often hold licenses that allow multiple types of work but specialize in specific services. Thermoscape may focus primarily on mold remediation or the available data may simply not capture their full service range. This is exactly why you need to contact them directly to confirm whether they regularly perform electrical work and can provide electrical-specific references before considering them for an electrical project.
Get a quote from Dollens Electric as they're clearly an electrical specialist. Only get a quote from Thermoscape after confirming they actively perform electrical work and can provide recent electrical project references. Comparing quotes only makes sense when both contractors have demonstrated expertise in the work you're hiring for. Otherwise you're comparing apples to oranges.
Electrical work requires specific code knowledge, load calculations, and safety expertise that differs significantly from other trades. A contractor without established electrical competency may miss permit requirements, create safety hazards, or fail inspections, costing you time and money to remediate. Both companies carry workers comp and bonds, but those protections don't guarantee technical expertise in electrical systems.

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.
