How to choose insulation contractors in Sunnyvale
- Compare scores, not star counts. A 5.0 from nine reviews is weaker evidence than a 4.7 from four hundred across six sources - the RHAWK Score already accounts for that.
- Check recency. Companies change hands and crews. Reviews from the last twelve months carry the most weight in our ranking for exactly that reason.
- Ask for three quotes. Sunnyvale pricing varies widely by scope and access; three ranked quotes give you a real market range.
- Confirm licence and insurance. We publish what public sources report - verify it directly before work starts.
How we research insulation contractors in Sunnyvale
Our crawlers read what real customers already wrote in public, then apply one identical formula to every company. No surveys, no self-reported data, no paid placement.
We scan up to 8 public review sources
Google, Yelp, Facebook, BBB, Houzz, Angi, HomeAdvisor, Thumbtack, Nextdoor, HomeStars and industry-specific sites - not one platform's opinion.
Every company gets the same 0-100 score
Rating quality (30), review volume (20), source breadth (15), recency (12), consistency between sources (10), owner responsiveness (8) and data completeness (5).
Nobody can buy a position
There is no paid placement in this ranking. Companies can claim their profile to keep data current, but claiming never moves them up.
Rankings refresh continuously
Our crawlers re-scan businesses on a rolling schedule, so a company that starts collecting bad reviews drops - usually within days.
