Red Flags When Choosing Vent Installation & Repair in San Lorenzo
Protect your San Lorenzo home and wallet by watching for these warning signs:
- Unrealistically low prices — "Whole house for $99" usually means aggressive upselling once inside your home
- No NADCA certification — The industry's minimum standard; companies without it may lack proper training
- Refusal to provide written estimates — Reputable companies document pricing before work begins
- No before-and-after documentation — If they can't show the difference, how do you know they cleaned?
- Pressure tactics — Legitimate companies give you time to decide
- No physical business address — Be cautious of companies operating only from unmarked vehicles
