An existing finish can be retained, matched, or replaced, and each choice needs a different description. S-Line Contractors provides commercial and residential construction in San Marino, CA, including new buildings and renovations shaped around the owner’s intended use.

Document the finishes you want to keep. For a San Marino renovation, photograph existing features and identify materials that should be retained, matched, or replaced. Review that list with the proposed layout and system changes. Clear preservation preferences help the team discuss construction details without assuming every existing surface will be removed.

Be specific about what matching means

If you want new work to relate to an existing surface, identify the detail that matters: color, texture, size, or pattern. Record where the original material remains and where replacement is proposed. Ask which choices need samples or closer review. A clear reference makes the discussion more useful than an instruction to make everything look the same.
