4 Contractor Pitfalls & Red Flags to Avoid in Boston

Watch Out

When requesting quotes for composite decking installation in Boston, 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 (~$430)

Some contractors skip filing the official Boston 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.
