Frequently asked questions
How should I choose a siding contractor in San Francisco?
Look for contractors with strong, recent local reviews, proper licensing and insurance, and relevant experience with your siding material. Ask for multiple written estimates, verify references, and confirm who will pull permits and handle inspections.
What factors affect the cost of siding replacement?
Cost depends on material type, the size and height of the house, the condition of the existing substrate, and labor complexity such as trim work or structural repairs. Get itemized quotes and compare material warranties and installation details rather than picking solely on price.
What should I check before signing a contract?
Ensure the contract lists scope of work, materials, start and finish dates, payment schedule, and warranty terms. Confirm the contractor’s license and insurance, and insist on retainage or final payment only after a satisfactory inspection and any required permits are closed.
