Verify the legal businessMake sure the business name on the estimate, contract, applicable registration or license record, insurance evidence, payment request, and warranty paperwork is consistent.
Ask for current insurance evidenceRequest current liability insurance and applicable workers’ compensation information. Confirm the named business, dates, coverage, and subcontractor responsibility for the project.
Get the exterior scope in writingAsk the installer to identify product, removal, disposal, wall preparation, wrap, flashing, trim, repairs, permits, access, schedule, cleanup, and warranty details.
Control changes before work beginsUse a written payment schedule and a written change-order process. Questions about unexpected conditions should be documented before extra work proceeds.
Unverifiable identityThe business will not provide stable identifying information, applicable registration or license detail, or current insurance evidence.
Thin or shifting scopeThe proposal gives a total without explaining material, preparation, water management, removal, repairs, permits, cleanup, or warranty responsibilities.
Pressure before comparisonYou are asked to sign before the written scope, payment, permit, and change-order questions are answered.
