Customer Reviews
Dollens Electric
Great Company, very happy every time they do work for us.

Consider Dollens Electric if...
- ✓ You need electrical work specifically: panel upgrades, generator installation, EV charging station, whole house rewiring, or solar integration
- ✓ Your project is primarily electrical and you want a specialist who focuses on this trade daily rather than subcontracting it out
- ✓ You value quick response times for electrical troubleshooting or repairs, which reviews consistently highlight
- ✓ You want detailed technical explanations about your electrical system from technicians who specialize in this field
Consider Sigura Construction if...
- ✓ Your project involves construction or remodeling: kitchen renovation, bathroom addition, bedroom extension, or structural modifications
- ✓ You need a general contractor who coordinates multiple trades (plumbing, electrical, framing) rather than hiring each separately
- ✓ Your project requires complex building permits and coordination with municipal agencies, which reviews indicate they handle effectively
- ✓ You're dealing with insurance claims for fire, water damage, or emergency repairs where construction management experience is valuable
Questions to Ask Before Hiring
- → If hiring Dollens for electrical work that might reveal structural issues: Ask who they recommend for construction coordination if the project expands beyond electrical scope
- → If hiring Sigura for a remodel with significant electrical components: Ask whether electrical work is performed in-house or subcontracted, and who specifically will handle panel upgrades or complex electrical installations
- → For either company: Request references from projects similar in scope to yours—electrical specialty work for Dollens, full construction projects for Sigura
The Bottom Line
Choose based on project type, not subjective preference. If your project is electrical—panel upgrades, generators, EV charging, rewiring, or solar—hire Dollens Electric directly. If your project is construction or remodeling—kitchens, bathrooms, additions, structural changes—hire Sigura Construction to manage the entire scope including coordinated electrical work. Both are veteran contractors with equivalent licensing, insurance, and bonding. The question isn't which is better, but which trade should lead your specific project. Don't hire a general contractor for standalone electrical work, and don't expect an electrical contractor to manage a multi-trade remodel.

Frequently Asked Questions
Dollens Electric can handle all electrical components of a kitchen remodel—new circuits, recessed lighting, appliance connections, and panel upgrades if needed. However, they don't perform the general construction, cabinet installation, plumbing, or tile work. You would need to coordinate other trades separately or hire a general contractor.
Sigura Construction can manage a panel upgrade as part of a larger remodeling project, but as a general contractor, they would typically coordinate this work through an electrical subcontractor rather than performing it with in-house electricians. If your project is exclusively electrical, a specialized electrical contractor would be the direct hire.
Dollens Electric is the appropriate choice for electrical emergencies like power outages, sparking outlets, tripped breakers, or burning smells from electrical components. Their reviews specifically mention quick response times for troubleshooting. Sigura Construction handles construction emergencies like fire damage or structural issues, not electrical service calls.
Sigura Construction should lead a bedroom addition since it involves structural work, framing, permits, and coordinating multiple trades. They can coordinate the electrical portion through their process. If you wanted to self-manage trades, you could hire Sigura for construction and Dollens for electrical separately, but this increases your coordination burden.

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.
