Top notch mechanical contractor. Very professional.
Consider LP Builders if...
- ✓ You need a general contractor for residential or commercial building construction projects, not specialized mechanical systems
- ✓ Your project involves typical construction work like remodeling, additions, or new construction rather than HVAC manufacturing or industrial fabrication
- ✓ You're working on a straightforward project in Sunnyvale and want a locally-based contractor with general construction capabilities
- ✓ You're comfortable proceeding with a contractor that has limited public review history by asking for direct references
Consider Therma if...
- ✓ You need commercial HVAC duct manufacturing, custom metal fabrication, or industrial mechanical systems rather than general construction
- ✓ Your project requires specialized capabilities like medical gas systems, process equipment, or precision fabrication work
- ✓ You're managing a commercial or industrial facility in Silicon Valley that needs mechanical contractor expertise

Questions to Ask Before Hiring
- → For LP Builders: Ask for references from recent projects similar to yours and inquire about their typical project types to confirm alignment with your construction needs
- → For LP Builders: Request examples of completed projects and how long their current crew has worked together given limited public review data
- → For Therma: Confirm whether they handle residential projects or if their focus remains exclusively on commercial and industrial mechanical work
- → For either company: Ask about project timelines, payment schedules, and whether they'll be the primary contractor or if your project requires coordination with other trades
The Bottom Line
These contractors serve completely different markets and you should choose based on your project type, not comparative ranking. If you need general construction work for a home or building project, LP Builders is the appropriate general contractor—just request references given their limited review history. If you need commercial HVAC duct manufacturing, custom metal fabrication, or industrial mechanical systems, Therma has proven technical capabilities and documented customer satisfaction. Don't hire a mechanical contractor for general construction or vice versa.

Frequently Asked Questions
LP Builders is the appropriate choice for home remodeling as a general contractor. Therma specializes in commercial mechanical systems and industrial HVAC fabrication, not residential construction work. If your remodeling includes HVAC work, LP Builders would coordinate mechanical subcontractors as part of the general construction project.
Therma serves commercial and industrial clients who are more likely to provide formal reviews of technical services. LP Builders' limited review history may reflect a smaller volume of completed projects or a different client base. Before hiring LP Builders, ask for direct references from recent customers and examples of completed work similar to your project.
Both companies qualify as experienced contractors with over five years of licensing. Therma's additional three years provides more time handling complex situations, which matters significantly for specialized mechanical work. For general construction through LP Builders, six years is sufficient experience, but verify they have specific experience with your project type.
Therma has strong capabilities in commercial mechanical work including HVAC systems, medical gas, and plumbing. However, their focus appears to be commercial and industrial facilities rather than residential projects. Contact them directly to confirm whether residential mechanical work fits their business model and minimum project requirements.

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.
