Frequently Asked Questions
Yes, particularly for older homes or complex projects. Wedge's 44 years means they've worked through multiple generations of building codes, material transitions, and regional weather patterns. This matters when tear-off reveals unexpected dry rot, outdated ventilation, or structural issues requiring experienced judgment calls. Sterling's 21 years is respectable, but their limited documented project diversity makes it harder to confirm they've encountered situations similar to yours.
This could reflect several scenarios: they may work primarily through repeat commercial clients or referral networks that don't generate public reviews, they may operate at smaller scale, or their online presence may simply be minimal. The concern isn't necessarily quality—it's that you're making a major investment without the customer verification patterns that Wedge provides. Ask Sterling directly for references and how they typically receive new business.
It depends on what you value. High owner involvement can mean personalized attention and direct accountability, but it may also indicate limited crew depth or capacity constraints. Wedge's feedback suggests they've built systems that deliver consistent quality without requiring the owner on every job. If your project has tight timelines or you value documented reliability over personal relationships, Wedge's organizational approach is advantageous.
If you need a full replacement, yes—ask Sterling directly about their experience with projects matching your scope. Leak repair requires different skills than coordinating multi-day tear-offs, disposal, material delivery, and crew scheduling. Wedge's feedback explicitly mentions full replacements, re-roofing, and complex projects completed on schedule. Don't assume capabilities; verify Sterling has recent, comparable projects they can reference.

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.
