Is Columbia Deck Builder the contractor?
No. This is an independent matching service; a local provider does the actual construction.
Is a callback guaranteed?
No — provider availability across Richland and Lexington counties shifts with demand.
Can this site give me an exact number?
No. Soil, drainage, and material choice all move the price, so treat anything here as a range, not a quote.
Is it worth gathering more than one estimate?
Usually — comparing written scopes side by side tends to expose real differences in approach and materials.
Who confirms licensing and insurance?
The homeowner does. Ask for documentation before any deposit is paid.
