What Does It Cost to Replace Garage Door Weather Stripping?
For most homeowners, replacing garage door weather stripping costs $45 to $180 for a single door and $80 to $300 for a double-wide door when a pro handles it, materials included. A simple bottom seal swap is on the low end; a full package with new bottom, side, and top seals lands higher, typically $200 to $450 for a complete job on a double door. If you do it yourself, you're mostly paying for materials, usually $30 to $150 depending on the type.
Step by step
-
1
Figure out which seal you actually need
There are three different seals and they're not interchangeable. The bottom seal (the rubber strip on the bottom edge of the door) is the most common culprit and usually $30 to $60 in materials. The side and top seals, often called the stop molding or jamb seal, run $40 to $80 for the sides and $20 to $40 for the top. Match the bottom seal to your door's retainer: U-shape, T-style, and bead/double-bead all use a specific groove. Snap a photo of the channel before you buy.

Measure your door width and double it
You need enough material to cover the full width plus a little extra. A standard single door is about 8 to 9 feet wide; a double is 16 feet. Bottom seal kits are sold by the foot or in pre-cut lengths, so buy slightly long and trim. This is the single biggest factor in your total, a double door simply needs twice the material and twice the labor.

Decide DIY versus pro honestly
Replacing a bottom seal that slides into an existing track is genuinely a 30-to-60-minute DIY job and costs you only materials, $30 to $150. But if the retainer track itself is damaged, or you're replacing side and top molding that's nailed to the frame, the labor adds up. Pros charge roughly $50 to $150 per hour, and most weather-seal jobs are billed as a flat $150 to $250 service call including parts.

Get an itemized quote, not a lump sum
Ask the company to break out parts versus labor and to confirm whether the price covers all three seals or just the bottom. A quote of $200 to $450 on a double door is normal for a full package; a single bottom seal alone should be well under $180 installed. If a quote comes in much higher, ask what's driving it, sometimes it's a new retainer track or a trip charge bundled in.

Budget a little extra for surprises
The most common add-on is a new bottom retainer (the aluminum channel the rubber slides into), which adds $20 to $50 if yours is bent, rusted, or the wrong profile. Concrete that's heaved or cracked under the door can also mean you need a thicker threshold seal, which is a separate product. Padding your budget by $50 covers most of these.
When to call a pro
Call a pro if your door is wider than a standard single, if the bottom seal sits in an aluminum retainer track that's bent or corroded, if you'd be working on a ladder for the side and top seals, or if you also notice the door isn't closing level or sealing evenly, which can point to a track, spring, or alignment problem rather than just worn rubber.

Can I replace just the bottom seal myself to save money?
Yes, and it's one of the most beginner-friendly garage door fixes. If your door has an aluminum retainer track, you just slide the old rubber out, spray the channel with a little soapy water or silicone, and feed the new seal in. You'll spend $30 to $60 on the seal and about half an hour. The job gets harder, and more worth hiring out, if the track is damaged or your seal is the older nailed-on style instead of the slide-in type.
How often does garage door weather stripping need replacing?
Most bottom seals last about 3 to 7 years, though sun exposure, road salt, and extreme temperature swings shorten that. Signs it's time: visible cracks or flattening in the rubber, daylight or drafts under the closed door, water seeping in, or leaves and bugs getting through. It's an inexpensive part, so replacing it early is cheaper than dealing with water damage or higher energy bills later.
Why is a double-car garage door more expensive to seal?
It comes down to material and labor. A double door is roughly 16 feet wide versus 8 to 9 feet for a single, so you need about twice the seal length, and the side and top runs are longer too. That's why a single door might run $45 to $180 installed while a double commonly lands at $200 to $450 for a full weather-seal package. The per-foot price is the same; there's just more of it.
Will new weather stripping actually lower my energy bills?
If your garage is attached or conditioned, or shares a wall with living space, then yes, sealing the gaps helps. Worn weather stripping lets in outside air that your HVAC system has to fight, especially through the big gap a failed bottom seal leaves. It won't transform your bill, but at $30 to $180 to fix, a good seal usually pays for itself in comfort and reduced heating and cooling loss, and it keeps out water, pests, and dust as a bonus.
