4 Contractor Pitfalls & Red Flags to Avoid in San Antonio
When requesting quotes for double-pane vinyl window replacement in San Antonio, unethical contractors frequently use these 4 tactics to inflate final invoices:
The "Low-Ball Upfront Quote" & Change Order Trap
Contractors submit an artificially low baseline bid, then slap $2,000–$4,000 in mandatory "unforeseen decking repair" or "underlayment upgrades" midway through installation. Always demand a fixed per-sheet plywood replacement cap written into the contract.
Skipping Municipal Permit Filing (~$195)
Some contractors skip filing the official San Antonio building permit to save time and pocket the permit fee. Unpermitted work voids manufacturer warranties and triggers heavy municipal stop-work fines during property resale inspections.
Reusing Old Flashing & Drip Edge
Reusing rusted chimney flashing, step flashing, or worn boots saves contractors $350 in materials but guarantees leaks within 24 months. Demand 100% brand-new flashing and ice barrier membrane in your scope of work.
Excessive Deposit Demands (>33% Upfront)
Never pay more than 20% to 33% upfront before materials are physically delivered to your home. Reputable contractors carry supplier credit accounts and draw progress payments only after passing key inspection stages.
