How much does garage door repair cost?

Garage door repair costs vary depending on the issue. Simple repairs like replacing a remote or adjusting sensors typically range from $75-$150. Spring replacement usually costs $150-$350 for a single spring or $250-$500 for a pair. Panel replacement can range from $200-$800 depending on the door type. At Garage Door Company Covina, we provide free estimates so you know exactly what to expect before any work begins. We also offer competitive pricing and stand behind our work with a lifetime warranty on all repairs.

How long does it take to replace a garage door?

A standard garage door replacement typically takes 3-5 hours from start to finish. This includes removing the old door, installing the new door and tracks, setting up the opener, and testing all safety features. More complex installations, such as custom doors, doors requiring structural modifications, or commercial installations, may take a full day or longer. Our experienced technicians work efficiently to minimize disruption to your schedule while ensuring quality installation.

Should I repair or replace my garage door?

The decision to repair or replace depends on several factors: the age of your door (doors over 15-20 years old often benefit from replacement), the extent of damage, energy efficiency needs, and your budget. Minor issues like broken springs, worn cables, or opener problems are usually worth repairing. However, if you're facing multiple repairs, significant panel damage, outdated safety features, or poor insulation, a new door may be more cost-effective long-term. We're happy to assess your door and provide honest recommendations based on your specific situation.

Weather Stripping & Seals in Covina: Why Your Garage Door Leaks (And How to Fix It)

2026-06-15 7 min read A2Z Garage Doors

A customer called last Tuesday with a flooded garage and a mystery draft that'd been costing her hundreds in energy bills. Within minutes, we found the culprit: deteriorated weather stripping around her bottom seal had cracked and separated from the frame. Water was pouring in during Covina's rare heavy rains, and conditioned air was escaping year-round. Weather stripping and seals are the unsung heroes of your garage door, and when they fail, the damage compounds fast.

Why Weather Stripping Fails (And Why You Should Care)

Your garage door's weather stripping and bottom seal create a barrier between the outside world and your interior space. These rubber or vinyl strips sit where the door meets the frame, the threshold, and the bottom edge. They block wind, rain, insects, and temperature swings.

Here's the problem: weather stripping degrades. UV exposure, repeated door cycles, temperature fluctuations, and moisture all wear the material thin. In Covina's hot summers and occasional winter cold snaps, thermal stress accelerates breakdown. Most weather stripping lasts between 5 and 8 years before cracking, hardening, or peeling away entirely.

I've seen homes where ignored weather stripping led to rodent infestations, structural water damage, and utility bills 40 percent higher than they should be. The cost of a replacement seal? Usually under $300. The cost of mold remediation or pest control after months of neglect? Thousands.

Signs Your Weather Stripping Needs Replacement

Visual inspection is your first line of defense. Open your garage door and look at the rubber or vinyl strips running along the sides and top. Are they cracked, compressed flat, or peeling away from the frame? That's a red flag.

Next, feel for a draft. On a breezy day, hold your hand near the threshold and around the door frame. You shouldn't feel outdoor air flowing inside. If you do, your seals are compromised.

Water stains on your garage floor, especially after rain, point directly to a failing bottom seal. Insects or spiderwebs clustering near the door frame suggest gaps where pests are entering. Check your heating and cooling costs too; a sudden spike in your utility bill often traces back to weather stripping failure.

We recommend an inspection every 2 to 3 years, especially if you're in an area with extreme temperature swings. Covina homeowners should particularly watch for wear during late summer, when months of heat exposure take their toll.

Types of Seals and When to Upgrade

Standard rubber weather stripping is affordable and effective for most residential doors. It's flexible, forgiving, and easy to replace. Vinyl alternatives offer better durability in high-UV environments and tend to last 8 to 10 years.

Silicone-based seals cost more upfront but resist cracking in extreme heat and cold. If your garage door opens into an unheated workshop or faces direct afternoon sun, silicone is worth the investment.

The bottom seal deserves special attention because it takes the most abuse. Traditional rubber seals compress and flatten. Bulb-style seals (shaped like a hollow tube) compress too but spring back slightly, offering longer life. Some advanced threshold seals include a drip edge that channels water away from your concrete floor.

If you're upgrading your entire garage door or recently installed a new one, this is the perfect time to invest in premium seals. Proper installation matters as much as material quality. Seals installed with gaps or misalignment fail faster and perform worse.

Our team at Garage Door Company Covina has replaced hundreds of seals and can recommend the right type for your specific door, climate exposure, and budget. We'll assess the draft, inspect the threshold, and provide a transparent estimate before any work begins.

DIY vs. Professional Replacement

Replacing weather stripping yourself is possible if you're handy. Most hardware stores stock generic seal kits. However, precision matters. Misaligned seals create gaps that defeat the entire purpose. Springs and tracks can be damaged during removal if you're unfamiliar with door mechanics.

We've seen DIY jobs go wrong when someone accidentally bent a track or overtightened fasteners, damaging the door frame. A professional replacement takes about 30 to 45 minutes and comes with a warranty. For that peace of mind, plus the guarantee that your seals are installed correctly, the cost difference is usually minimal.

Frequently Asked Questions

How often should I replace garage door weather stripping? Most weather stripping lasts 5 to 8 years depending on climate and UV exposure. Inspect annually and replace as soon as you notice cracks, compression, or peeling. Covina's heat accelerates wear, so plan on replacement sooner rather than later.

Can I replace the bottom seal myself? Yes, if you're experienced with basic home repairs. However, misalignment is common, and accidental track or frame damage can occur. Professional installation ensures proper fit, warranty coverage, and correct alignment every time.

What's the difference between a bottom seal and a threshold? The bottom seal is the rubber or vinyl strip attached to the bottom of the door itself. The threshold is the metal or rubber strip mounted on the floor where the door closes. Both must seal tightly to block drafts and water.

How much does weather stripping replacement cost? A standard replacement typically ranges from $150 to $400 depending on door size and seal type. Premium silicone seals cost more. Call us for a specific estimate based on your door.

Why is my garage door leaking water if the seals look okay? Seals can appear intact but have invisible micro-cracks or gaps at corners and joints. Water pressure during heavy rain exploits these weak points. A professional inspection reveals damage that visual checks miss.
