How to Replace Weather Stripping & Seals in New Braunfels: DIY vs. Professional
2026-08-03 7 min read A2Z Garage Doors
Most people don't think about their garage door until something stops working. Weather stripping and seals are no exception. But here's the truth after 15 years on the job: replacing them early saves you money on energy bills and prevents bigger headaches down the road. The short answer is yes, you can DIY basic bottom seal replacement, but the threshold seal and perimeter stripping often need professional attention.
Why Weather Stripping Fails (And What Happens When It Does)
Your garage door's weather stripping takes a beating. In New Braunfels, we see intense sun, humidity swings, and occasional cold snaps. The rubber and vinyl seals degrade from UV exposure, temperature shifts, and constant opening and closing. Most seals last 5 to 7 years before they crack, shrink, or lose their compression.
When they fail, you get drafts. Cold air sneaks in during winter. Hot air escapes your cooled space in summer. Your HVAC works overtime. The energy loss adds up faster than most homeowners realize, especially in a Texas climate where cooling costs spike fast.
If you've noticed visible cracks, gaps, or daylight showing under your garage door, it's time to act. We covered signs your weather stripping and seals are failing in New Braunfels in detail before, so check that out if you're unsure whether your door needs work.
The DIY Route: Bottom Seal Replacement
The bottom seal (also called the bottom weatherstrip) is the easiest piece to replace yourself. It's the rubber blade that runs the full width of your door at the bottom. Here's what you need:
1. A new bottom seal kit (usually under $50) 2. A socket wrench or screwdriver set 3. About 30 minutes of time
The process is straightforward. Open your garage door halfway. Remove the bolts holding the seal track to the bottom of the door. Slide out the old rubber seal. Insert the new one into the track. Bolt it back down. Tighten everything and test the door operation.
One tip from my years in the field: don't skimp on the replacement seal quality. A cheap threshold product will shrink and fail faster. Mid range seals from reputable manufacturers hold up better in our Texas heat.

When to Call a Professional
The perimeter stripping (top and sides) is trickier. It's glued to the door frame, and removal often damages the frame. You'll need to scrape, clean, and reapply adhesive properly. Gaps here let in rain and rodents, not just drafts. One bad install costs you more in repairs than a professional job would have.
The same goes for threshold seals on the floor. These take intense wear from foot traffic, wheels, and weather exposure. Installation requires precise alignment and proper fastening. If it's not perfect, you'll get standing water after rain or uneven wear on your door's bottom.

Frequently Asked Questions
Can I replace weather stripping myself on a sectional garage door? Bottom seals, yes. Perimeter stripping, rarely. Sectional doors have multiple panels, and the stripping alignment must be perfect across all seams, or drafts persist. Professional installation ensures no gaps between sections.
How long does professional weather stripping installation take? Most jobs take 2 to 4 hours depending on your door size and how much old adhesive needs removal. We often complete it same-day, so you're sealed up before evening.
What's the difference between a bottom seal and a threshold seal? The bottom seal is the rubber blade in the track at the door's bottom. The threshold is the floor piece underneath. Both are critical, but the threshold takes more wear and requires precise installation.
Will replacing seals reduce my energy bill? Yes, noticeably. Sealing drafts can cut heating and cooling costs by 10 to 15 percent, depending on your door's condition and your current thermostat settings.
Do weather seals come with a warranty? Most quality seals carry 3 to 5 year warranties. Professional installation usually adds a labor warranty too. Check your receipt for details.
