Top notch mechanical contractor. Very professional.
Consider Craft Builders Construction if...
- ✓ You have a residential project like a kitchen remodel, roof replacement, electrical upgrades, or solar panel installation that requires a general contractor familiar with homeowner needs
- ✓ You value detailed communication and guidance through the decision-making process, as reviews consistently mention helpful explanations and customer service
- ✓ You prefer working with a contractor who has demonstrated experience managing the types of projects homeowners typically undertake
- ✓ Your project is in Morgan Hill or nearby Santa Clara County areas where they have established local presence
Consider Therma if...
- ✓ You need commercial mechanical contracting services, HVAC duct manufacturing, or industrial process equipment fabrication rather than residential work
- ✓ Your project requires custom metal fabrication with precision manufacturing capabilities, such as specialty ducting components or custom electrical gutters
- ✓ You're working on a commercial or industrial facility that needs plumbing systems, medical gas systems, or complex HVAC installations
- ✓ You need a contractor with high-volume manufacturing capacity and technical expertise in mechanical systems for commercial applications
Questions to Ask Before Hiring
- → Ask Craft Builders for references from residential projects similar to yours, particularly if you're planning a complex remodel or solar installation
- → Ask Therma whether they take on residential projects and if they have the customer service structure to support homeowner clients, as their focus appears primarily commercial
- → Confirm project timelines with each contractor, as commercial-focused companies may have different scheduling approaches than residential contractors
- → Ask about warranty terms and service availability after project completion, particularly important given their different market focuses
The Bottom Line
These contractors serve different markets, so your choice should be straightforward based on project type. If you're a homeowner planning a kitchen remodel, roof replacement, electrical work, or solar installation, Craft Builders Construction has the relevant residential experience and customer service approach your project requires. If you need commercial mechanical contracting, custom metal fabrication, or industrial HVAC systems, Therma has those specialized capabilities. Don't hire a commercial contractor for residential work or vice versa unless they explicitly confirm they serve your market and have relevant project examples to share.

Frequently Asked Questions
Therma's reviews and project history emphasize commercial mechanical work and industrial fabrication, not residential HVAC service. While they have the technical capabilities, their business model appears focused on commercial clients. Ask them directly if they take residential projects and whether they have processes in place for homeowner communication and scheduling.
Craft Builders' 11-year track record centers on residential work including kitchen remodels, roofing, and solar installations. Their reviews highlight customer service and communication approaches typical of residential contractors. If you have a commercial project, they may not be the best fit compared to a commercial-focused contractor.
This depends on project complexity. Craft Builders' residential experience means they understand homeowner needs and communication, though HVAC isn't listed among their primary services. Therma has deep HVAC expertise but focuses on commercial work. Ask Craft Builders if they perform residential HVAC installations, and ask Therma if they service residential clients.
The two-year licensing difference is less significant than their completely different market focuses. Craft Builders' 11 years in residential work versus Therma's 9 years in commercial mechanical contracting means they've developed expertise in fundamentally different project types, client relationships, and technical specializations.

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.
