Bottom seals and thresholds — the overlooked weatherproofing point

The bottom seal is the most frequently replaced component on a residential garage door because it contacts the floor on every cycle, compresses under the door's weight, and endures abrasion, UV exposure, and freeze-thaw stress season after season. When it hardens, tears, or fails to contact the floor across the full width of the door, the result is visible: a gap that admits water during rain, drafts in winter, insects in summer, and leaves that blow under the door year-round. BSD Garage Door replaces bottom seals and installs threshold systems across MA — most replacements completed in under 30 minutes. Bottom gasket and threshold seal replacement for Franklin garages. Stops water, leaves, and drafts at the floor line — quick replacement that restores weather protection without full door removal.

For garages with uneven concrete slabs — which is common in MA homes older than 20 years where frost heave and settling have created low and high spots — a standard T-slot gasket may not close the gap uniformly across the full door width. In those cases, a threshold seal provides a secondary barrier by raising the surface on the slab side. We assess the floor profile during the service call and recommend the seal configuration that closes the gap correctly without over-compressing the bottom section when the door is down.

Seal and threshold selection guide

• T-slot EPDM gasket (4.5-inch) — the standard replacement for most residential sectional doors. Fits the aluminum retainer on the door's bottom section. Correct spec depends on door manufacturer and retainer profile.
• T-slot vinyl gasket — slightly more resistant to extreme cold temperatures than EPDM; maintains flexibility at sub-zero conditions common in northern MA winters.
• Threshold seal — a foam, rubber, or vinyl strip adhered to the concrete floor. Provides a secondary air and water barrier under the door, particularly effective when the slab has low spots the door gasket cannot compress against.
• Combination system — a threshold seal combined with a new bottom gasket provides the most complete protection and is recommended for garages where water intrusion has been an ongoing problem.

In MA winters, a bottom seal that is frozen to the concrete slab when the opener activates will tear itself free — or the gasket retainer will be ripped from the door section. The fix is replacing the seal before it fails this way, not after. BSD Garage Door inspects the bottom seal condition at every tune-up visit and quotes replacement when the material has hardened past its designed compression range.
