Coastal-to-inland climate transition — hardware choices matter
Homes west of Melrose Drive get enough marine air to make salt corrosion a real factor over 8–10 years, even if it's not as aggressive as a Del Mar bluff top. Homes east of Twin Oaks Valley Road see inland heat and cold-swing conditions that stress springs and shrink weather seals.
For western Vista we upgrade to galvanized cables and sealed-bearing rollers as a mid-tier install, not full coastal spec. For eastern Vista we prioritize high-cycle springs rated for temperature range and quality weather stripping that doesn't shrink out of shape in the first summer. Same city, meaningfully different install specs by neighborhood.
