Common questions before the walkthrough.
These answers preserve the live FAQ intent while using the current approved phone, warranty, financing, and claim standards.
How much is a typical project?
Every estimate is built around the scope, surface condition, access, prep, and finish system. Residential projects over $5,000 can review financing options through Wisetack.
Can I receive an estimate over the phone?
It is hard to give a meaningful painting estimate by phone alone. A.G. Williams reviews the property, surfaces, access, and prep needs before preparing a written scope.
What does the 5-year warranty on workmanship cover?
Published warranty language is a 5-year warranty on workmanship for residential projects. Current warranty terms remain the source of truth for coverage, exclusions, and claim handling.
How messy is painting work?
Crews plan protection before work starts, including floor protection, furniture covering, masking, and jobsite cleanup. Older homes are reviewed for Lead-Safe + RRP requirements.
What if I have not picked colors yet?
A.G. Williams can help narrow color decisions around the room, light, trim, flooring, and finish goals before materials are ordered.
Do I have to be home?
Access, communication, and walkthrough timing are coordinated before work begins. The estimate and project plan should make those details clear before the crew starts.
