Weather Stripping & Seals Repair Cost in Startup: What You'll Actually Pay
2026-06-29 7 min read A2Z Garage Doors
Weather stripping and seal replacement typically runs $150 to $400 in the Startup area, depending on which seals need work and your door's condition. Bottom seal replacements alone cost $100 to $250. The real answer depends on what's actually failing, not what a salesperson thinks sounds good.
I've been running Garage Door Startup for years, and I see homeowners overpay for seals constantly because they don't know what to ask for. Let me cut through the confusion about weather stripping and seals so you can make a smart decision for your garage.
Understanding the Real Problem
Your garage door has multiple seals. The bottom seal keeps rain and pests out. The threshold sits below that. Side seals run vertically. Top seals sit above the door opening. Each one serves a job, and each costs different money to replace.
Most homeowners notice a problem only when they see water pooling, feel a draft, or spot critters. By then, you've been losing heat or cooling for weeks. A quick inspection catches these issues before they get expensive.
Bottom Seal and Threshold Costs
The bottom seal takes the most abuse. It flexes every time your door opens and closes. After 5 to 7 years, rubber hardens and cracks appear. Replacing just the bottom seal costs $100 to $180 near Startup.
If your threshold is damaged too, add another $80 to $150. Many garage doors have both issues at once because they wear together. A threshold that's cracked or warped lets drafts straight in, making your HVAC work harder.
We often see homeowners try to patch these with caulk or tape. That's a band-aid. A proper bottom seal replacement takes two hours and gives you years of protection.
Side and Top Seal Pricing
Side seals are cheaper because they take less wear. Expect $60 to $120 per side if you need both replaced. Top seals run $80 to $150 depending on your door width.
If you're replacing multiple seals at once, ask about a package estimate. Most shops, including ours, will discount the labor when you're doing three or four seals in one visit. Same-day service is possible if you call early in the morning.

What Affects Your Cost
Door size matters. A 9-foot-wide door costs more to seal than an 8-foot door just because there's more material. Material type affects price too. Rubber seals are standard. Silicone or foam options cost a bit more but last longer in harsh weather.
If your door frame is bent or the panels are warped, sealing becomes harder. We might need to check your track alignment before sealing. That's extra time and occasionally extra cost, but it's the right way.
Your door's age and condition also plays a role. Older doors sometimes have discontinued seal styles. We stock common ones, but specialty seals might take a day or two to source.
How to Get an Accurate Estimate
Don't guess. A proper estimate requires an on-site look at your door. We'll check which seals are actually failing, measure your door, and quote you honestly. No padding, no upsells.
If you're already planning new garage door installation, seals come standard with a new door. If your current door is still solid but seals are failing, repair is the smarter move.

Frequently Asked Questions
How long do garage door seals last? Most rubber seals last 5 to 7 years in the Pacific Northwest climate. Silicone versions can stretch to 8 to 10 years. Regular cleaning and checking extend life further.
Can I replace seals myself? Simple bottom seals are possible for handy homeowners. Side and top seals need more care. If your door is under tension from springs, leave it to a pro. Injuries happen fast.
Will new seals reduce my heating bill? Yes. A failing bottom seal or threshold lets heated air escape. Replacing seals can cut garage heating loss by 30 to 50 percent depending on current condition.
What's the difference between a seal and weather stripping? They're often the same thing. Weather stripping is the broader term for any material that seals gaps. Garage doors use rubber or foam seals specifically designed for the repeated movement.
Should I replace all seals at once? Not necessarily. Replace what's actually failing. If only the bottom seal is cracked, fix that. If multiple seals are worn, a package repair makes sense and saves labor cost.
