If your garage feels drafty or you notice bugs creeping in around the edges, worn weather stripping and seals are the culprit. A damaged bottom seal or threshold lets conditioned air escape, drives up utility bills, and invites rodents inside. The good news: replacing weather stripping & seals in Mountain View is one of the cheapest fixes you can make.
Your garage door's seal system takes a beating. Sunlight breaks down rubber. Temperature swings from Mountain View's mild winters to warmer summers cause expansion and contraction. Dust accumulates. After five to seven years, most seals start cracking or peeling away from the frame.
A failing bottom seal is the biggest culprit. This rubber strip sits at the lowest point of your door and absorbs the most stress. When it deteriorates, you lose thermal efficiency fast. In a climate like ours, that might not mean freezing pipes, but it does mean higher cooling costs when summer heat creeps in.
Beyond comfort, a compromised threshold invites pests. Gaps wider than a quarter inch give insects and rodents direct access to your garage and potentially your home.
Not all seals fail at the same rate. Understanding which ones matter most saves you money on unnecessary work.
Bottom seal: Wears out fastest. Expect replacement every 5 to 7 years if you open and close your door daily. Cost is usually $150 to $300 for parts and labor.
Side seals: Run along the vertical edges. These last longer (8 to 10 years) because they bear less direct stress. Replacement typically costs $100 to $200 per side.
Top seal: Sits above the door. Rarely fails first, but when it does, water can seep into your garage during heavy rains. Less common in Mountain View's dry climate, but worth checking.
The threshold (that metal or rubber piece at ground level) also wears out and may need replacement if it's warped or missing chunks.

Check your seals yourself first. Open your garage door and look for visible cracks, peeling rubber, or gaps. Shine a flashlight along the bottom seal and around the sides. If you see daylight streaming through, replacement is overdue.
Feel around the threshold for soft spots or separation from the door frame. If it moves when you push on it, it needs attention.
Another telltale sign: drafts or unexplained humidity in your garage, especially after rain. These point directly to seal failure.

You can buy replacement seals online for $30 to $80 and attempt installation yourself. If you're handy and comfortable working around a garage door, it's doable. Most seals slide into grooves or attach with adhesive.
However, there's a catch. If your door isn't perfectly level or the tracks are bent, new seals won't seal properly. Improper installation wastes money. Professionals ensure the door sits true before installing seals, guaranteeing they actually work.
For most Mountain View homeowners, hiring a pro makes sense. Same-day availability means you're not waiting weeks, and the labor cost is modest compared to energy waste.
Seals are just one part of garage door maintenance. Regular lubrication, spring inspections, and threshold checks prevent bigger problems down the road. If your door has never had a maintenance tune-up, now's a good time. Our garage door maintenance guide covers what to check quarterly.
Replacing worn weather stripping & seals is preventive maintenance at its finest. You spend a little now to avoid drafts, pests, and energy waste later. It's the budget-conscious move every homeowner should make.

How long do garage door seals last? Most seals last 5 to 7 years depending on climate and door usage. Mountain View's temperature swings accelerate wear. Inspect seals annually and replace when you notice cracks, peeling, or visible gaps around the frame.
Can I replace just the bottom seal without replacing the sides? Yes. The bottom seal typically fails first and can be replaced independently. However, if side seals are also cracked, replacing everything at once is more cost-effective and ensures uniform protection against drafts.
What's the difference between a bottom seal and a threshold? The bottom seal is the rubber strip attached to the bottom of the door itself. The threshold is a metal or rubber piece mounted on the garage floor where the door closes. Both are essential for a tight seal.
Will new seals fix my drafty garage? If drafts are caused by worn seals, yes. But if your door is misaligned or tracks are bent, new seals alone won't solve the problem. A professional inspection identifies the root cause before you spend money.
Is weather stripping maintenance covered in a garage door service plan? Some plans include inspections. Others charge separately for replacement. Ask about this when getting an estimate so there are no surprises on the invoice.
