# Weatherstripping: A Complete Guide for Homeowners
Weatherstripping is one of the most important yet often overlooked components of your garage door system. Proper weatherstripping keeps out rain, snow, dust, pests, and drafts while helping to regulate temperature and reduce energy costs. At Elkton Garage Doors, we've seen how proper maintenance of weatherstripping can save homeowners thousands in energy costs.
Why Weatherstripping Matters
Your garage door is likely the largest moving part of your home, and the gaps around it can let in significant amounts of outside air. Quality weatherstripping:
- Reduces energy costs by preventing heat loss in winter and keeping cool air in during summer - Protects against moisture that can damage stored items and promote mold growth - Keeps pests out including insects, rodents, and other unwanted visitors - Reduces noise from outside traffic and neighborhood activity - Prevents dust and debris from entering your garage
Types of Garage Door Weatherstripping
Bottom Seal (Astragal)
The bottom seal attaches to the bottom of your garage door and creates a barrier between the door and the floor. There are several types:
- T-style seals: Fit into a retainer attached to the door bottom - Bulb seals: Round or beaded design that compresses against the floor - Threshold seals: Attach to the floor rather than the door
Side and Top Seals
These seals attach to the door frame and compress against the door when closed:
- Vinyl or rubber strips: Most common and affordable option - Brush seals: Made of dense bristles, good for uneven surfaces - Foam tape: Easy DIY option but less durable
Signs You Need New Weatherstripping
Watch for these indicators:
1. Visible gaps between the door and frame when closed 2. Light coming through around the edges 3. Water or snow entering the garage 4. Increased energy bills without other explanation 5. Cracked, brittle, or missing sections of existing weatherstripping 6. Pests entering through the garage
Installation Tips
While weatherstripping replacement can be a DIY project, proper installation is key:
1. Measure carefully before purchasing materials 2. Clean surfaces thoroughly before applying new seals 3. Replace retainers if damaged rather than just the seal 4. Test the door operation after installation 5. Consider professional installation for bottom seals
Maintenance
Extend the life of your weatherstripping with regular care:
- Inspect seasonally for wear and damage, Clean with mild soap and water, Apply silicone lubricant to keep seals flexible, Address damage promptly before it worsens
