Top notch mechanical contractor. Very professional.
Consider Craft Builders Construction if...
- ✓ You need typical residential work like kitchen remodeling, roof replacement, electrical upgrades, or solar panel installation that homeowners commonly hire contractors to perform
- ✓ You want a contractor experienced in communicating with homeowners and explaining project options in accessible terms, as reflected consistently in their customer feedback
- ✓ You value established experience with residential building codes and working in occupied homes, which Craft Builders has developed over 11 years
- ✓ Your project requires coordination across multiple trades like electrical, structural, and finish work that a residential general contractor typically manages
Consider Therma if...
- ✓ You need custom HVAC duct manufacturing or specialty metal fabrication components for a commercial property or industrial application
- ✓ Your project involves commercial mechanical systems like medical gas installation, steam systems, or process equipment that requires specialized expertise
- ✓ You're managing a facility in Silicon Valley and need a mechanical contractor with high-volume manufacturing capacity and precision fabrication capabilities
- ✓ You have a unique residential mechanical need requiring custom metalwork that standard residential contractors don't typically fabricate in-house
Questions to Ask Before Hiring
- → Confirm with Therma whether they actually take on residential projects, and if so, ask for specific examples of homes they've worked in and references from homeowners rather than facility managers
- → Ask Craft Builders about their experience with any specialized mechanical work if your project has unusual HVAC or fabrication requirements beyond standard residential scope
- → If considering Therma for residential work, ask how their pricing and minimum project requirements compare to residential contractors, as commercial contractors often have different cost structures

Unless you need commercial mechanical fabrication, custom industrial ductwork, or specialized process equipment, Craft Builders Construction is the appropriate choice for residential work. With 11 years serving homeowners on kitchens, roofing, electrical, and solar projects, they operate in the residential market with customer feedback emphasizing helpful communication and professionalism. Therma is a commercial mechanical contractor focused on manufacturing and industrial systems. For typical home improvement projects, contact Craft Builders.

Frequently Asked Questions
You probably wouldn't unless you have a very specific mechanical fabrication need. Craft Builders serves homeowners with standard residential projects, while Therma manufactures ductwork and fabricates metal components for commercial facilities. If you're a homeowner planning a kitchen remodel or roof replacement, Therma isn't designed for your project type.
Not necessarily, and Therma may not even take residential projects. Commercial mechanical work involves different codes, materials, scale, and customer relationships than residential construction. Craft Builders' experience communicating with homeowners and navigating residential permitting is more relevant for home projects.
No. Years licensed and bond amounts don't indicate they serve the same market. Craft Builders' 11 years are spent on residential projects with homeowner customers, while Therma's 9 years focus on commercial facilities. Their actual project portfolios show completely different specializations.
Possibly, since they manufacture custom ductwork, but you'd need to confirm they work on residential projects at all and compare their pricing to residential HVAC contractors who also do custom work. Their business model is built around commercial volume manufacturing, which may not align with single-home project economics.

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.
