Common Door and Window Problems in Contra Costa County Homes
From inland heat in Brentwood and Antioch to coastal damp in Orinda and Lafayette, Contra Costa homes face a mix of climates. These are the issues we see most often.
Drafty windows during hot inland summers
East county heat and Diablo winds expose tired seals and old single-pane glass — comfort and energy bills suffer.
Old aluminum windows with poor energy performance
1970s and 80s aluminum frames conduct heat and cold and rarely meet today's Title 24 standards.
Failed glass and fogging between panes
Broken seals on dual-pane units cause permanent fog, water spots, and lost insulation value.
Front doors with daylight gaps or damaged jambs
Warped slabs, sagging hinges, and weatherstripping gaps let in light, air, water, and pests.
Patio doors that are hard to slide or poorly sealed
Worn rollers, bent tracks, and failed weatherstripping on aging sliders waste energy and feel unsafe.
Security concerns at front entries and patio openings
Weak strike plates, single-cylinder locks, and exposed sliders are common entry points worth upgrading.
Dry rot or exterior damage around openings
Failed flashing, stucco cracks, and rotted trim around windows and doors require proper repair before replacement.
Outdated curb appeal in older neighborhoods
Original builder-grade doors and windows hold back the look — and resale value — of established Contra Costa homes.
