How does Bonita's climate affect this service?
Bonita sits 5 miles inland of the bay along Sweetwater Valley. Salt influence is moderate, summer heat is real, and larger lots mean more two-car and three-car garages than the rest of South Bay.. South Bay seals handle coastal moisture in the west and dust in the east.
How often do garage door seals need replacement?
Bottom U-seal: every 5 to 8 years in San Diego's UV and coastal-salt conditions. Perimeter seals: 8 to 12 years. If you're seeing daylight at the edges when the door is closed or water puddles inside after a storm, the seal is done regardless of age.
Can I replace the bottom seal myself?
On most doors, yes, the U-seal slides into a track on the bottom panel and it's a 20-minute job. Where it goes sideways: an old corroded aluminum retainer that needs to come off and be replaced (that needs the door tension neutralized), or a custom profile that isn't a standard U. If you're not sure which you have, we can do both.
