Bottom Seal/Astragal Replacement in Orange County, CA
A worn bottom seal (astragal) lets in wind, water, and critters—and makes your garage louder and draftier. Urgent Garage Doors replaces bottom seals and aluminum retainers with the right profile for your door and slab—leveled, trimmed, and silicone-sealed for a tight, durable fit.
✓ Coastal-ready: Materials and fasteners that stand up to salt air.
✓ Right profile for your door: T-style, bulb, U-channel, and beaded seals.
✓ Cleaner close: Quieter landing, fewer drafts, and better energy control.
✓ Add-ons available: Aluminum retainer kits and threshold ramps for uneven slabs.

What our Clients think about us
Your satisfaction is our priority.
What Is a Bottom Seal/Astragal Replacement?
A swap of the flexible weather strip at the door’s bottom edge (and aluminum retainer if damaged).
We choose a seal profile that matches the door’s track and your slab conditions, then trim and silicone-seal ends to block capillary leaks—finishing with a travel/force tune so the door closes cleanly.
Why Choose Urgent Garage Doors
One accountable team: Inspect → measure → replace → tune under a single tech/PM.
Every configuration: Single/double doors, tilt-up or sectional, wood/steel/composite.
Occupied-space pros: Floor protection, debris capture, and same-day cleanup.
Door-first approach: We check balance and limits so seals seat correctly and openers aren’t overworking.
Immediate Actions (What to Do Now)
Check daylight under the door—note which corners leak and any gaps > ¼".
Snap photos of the existing retainer (aluminum track) and seal profile.
Tell us if the floor is uneven or has a settle dip—we may recommend a threshold.
Call our team—we’ll confirm your seal type, width, and retainer condition and schedule a quick service window.
Common Scenarios We Handle
Water tracks after rain, especially at corners or low slab spots
Daylight and drafts under older insulated steel or wood doors
Rodent/bug intrusion through torn or shrunken seals
Corroded retainers near the coast that snag or tear new seals
Noisy “slam” because a hardened seal won’t compress
Inspect & Measure
Identify retainer type (T-slot, U-channel, beaded), door width/thickness, slab flatness, and corner gaps; document with photos.
Spec the Seal
Choose bulb vs. T-style vs. U-channel; select rubber, EPDM, or vinyl (EPDM preferred for UV/salt); add threshold/shims if floor is uneven.
Remove & Prep
Lift door, de-tension pressure on the seal, remove old strip, scrape debris, clean retainer grooves; replace retainer if bent/corroded.
Install New Astragal
Feed new seal evenly, lubricate slots as needed, align center marks, trim to width; silicone-seal cut ends and fastener holes.
Tune & Test
Set opener travel/force limits, verify photo-eye operation, cycle door to check compression and eliminate daylight.
Cleanup & Care
Wipe bottom panel, remove debris, and provide care tips (light silicone wipe 1–2x/yr).
What’s Included
Gap/retainer assessment and measurements
Premium bottom seal (profile/material matched to your door)
Aluminum retainer repair/replacement if required (quoted if damaged)
End sealing (silicone) and corner fitment for uneven slabs
Opener tune & safety check (limits, force, photo-eyes)
Cleanup + care guide with replacement date recorded
Costs & Timelines (What to Expect)
Typical duration: 25–60 minutes per single/double door; add time for retainer replacement or threshold install.
Key cost drivers: Door width, seal profile/material (EPDM lasts longer), retainer condition, slab unevenness (threshold ramps), and coastal hardware upgrades.
Estimate clarity: Line items for seal, retainer (if needed), installation, and optional threshold.
Insurance & Claims Help
After storm/flood events, we can document before/after photos and materials used.
Separated scopes: Temporary drying/cleanup vs. seal/retainer replacement priced clearly.
(Coverage varies by policy; not financial advice.)
Risks of Waiting (Why Act Now)
Water intrusion leading to mold/odor, damaged finishes, or rusting track hardware
Pest access through gaps at corners and center dips
Higher energy loss and uncomfortable drafts in attached garages
Premature opener wear from slamming against hardened seals
Methods, Materials & Quality Standards
Materials: EPDM for UV/salt resistance; quality vinyl as value option; co-extruded seals for long wear.
Profiles: Bulb for uneven slabs; T-style for standard retainers; U-channel/beaded for specific manufacturers; dual-fin where extra sweep helps.
Retainers: Anodized/powder-coated aluminum; stainless fasteners for coastal installs; straightness verified before feeding seal.
Thresholds (Optional): PVC/EPDM ramps adhered to slab to fill dips; beveled edges for trip resistance; compatible adhesives only.
Seal Ends: Silicone-locked to prevent capillary leaks and shrink pullback.
Compliance: Opener UL 325 force/travel re-check; photo-eye alignment confirmed.
Frequently Asked Questions
Which seal profile do I need?
We match to your retainer type and slab. Bulb handles uneven floors; T-style fits common retainers; U-channel/beaded for certain brands.
How long do seals last?
Typically 2–5 years; EPDM lasts longer in sun/salt. We can set reminders for seasonal inspections.
Do I need a new retainer?
Only if bent/corroded. A new retainer protects the new seal and feeds smoothly.
What if I still see daylight after replacement?
We can add a threshold ramp or adjust panel alignment/balance; we’ll inspect and advise.
Will this make the door quieter?
Yes—fresh, soft seals cushion the landing and reduce vibration.
Is this DIY?
Feeding seals can seem simple, but mis-set opener limits or damaged retainers cause leaks/noise. We install, tune, and warranty the work.
