Exterior Improvements San Marcos
Exterior work in San Marcos shows up as cracks, chalked paint, and dry-rot fascia long before most homeowners notice. Hillside coastal influence — morning marine layer, warm afternoons, and salt-tinged air on west-facing elevations in San Elijo Hills. A window-and-door project often surfaces stucco cracks that were there but invisible; exterior paint almost always needs to follow because the new trim doesn't match the old.
Why San Marcos homes need a different exterior improvements spec
The San Marcos exterior work that follows a window or door job: stucco crack repair at window corners, a full-elevation repaint where the old color oxidized a full shade lighter than the original spec, and dry-rot fascia repair behind the gutters. We schedule it as a follow-on phase so the house gets addressed once, not twice.
