Why Weather Sealing Matters in Plano, TX
Every year, Plano residents prepare for the blistering heat and sudden summer storms that sweep through North Texas. While homes are built to withstand much of this, one often-overlooked area is the garage. Unfortunately, many homeowners do not realize the importance of proper weather sealing until damage has already occurred.
Last summer, one of our customers in Plano experienced significant flooding in his garage following a strong thunderstorm. Despite having a sturdy garage door, water poured in through a cracked bottom seal and a deteriorated side seal, resulting in water-damaged storage boxes and mold growth on the baseboards. A full replacement of the garage door seal system, including a new threshold seal and EPDM rubber bottom seal, solved the problem and helped the homeowner weatherproof his garage for future storms.
According to the National Weather Service, Plano averages more than two dozen thunderstorm days per year. When you combine these frequent storms with intense summer heat, your garage becomes vulnerable to everything from water intrusion and drafts to pest infestations and excessive humidity. Installing proper weather sealing and performing regular seal inspections is essential for protecting your home.
The keyword at the heart of this discussion is weather sealing. This guide will help you understand what it is, why it matters, how to check it before storm season, and how Rayburn Garage Doors Co. can help keep your garage protected.
What Is Garage Door Weather Sealing?
Weather sealing refers to the installation of materials around the perimeter of your garage door to block out rain, wind, extreme temperatures, dust, pests, and debris. These materials include a combination of garage door seals, threshold seals, foam weatherstrip tape, rubber door strips, side seals, and door sweeps. All of these components work together to ensure airtight insulation and protect your garage from external threats.
A well-sealed garage includes a garage door bottom seal made of EPDM rubber or vinyl, a threshold seal that adheres to the garage floor, a door sweep to block airflow under the door, and foam tape or vinyl trim for the sides and top of the door. In some cases, magnetic door strips or adhesive rubber seals are used to improve contact between the door and the frame. Silicone caulk is applied at joints to fill any remaining gaps and enhance moisture resistance.
These materials not only prevent water infiltration but also help regulate the garage’s temperature, especially when paired with garage insulation or a window insulation kit. By combining weatherproofing techniques with thermal curtain installation, air leak repair, and proper sealant application, you can achieve Energy Star-level performance and reduce your energy bills significantly.
Why Is Weather Sealing Important in Plano?
Plano’s summers can be unpredictable and intense, often involving sudden thunderstorms, high humidity, and extreme heat. These conditions can wreak havoc on poorly sealed garages, leading to several major issues.
Water Damage Prevention
When thunderstorms hit, water can seep into your garage through even the smallest gaps if your under-door seal or threshold seal is cracked or missing. Over time, this can cause mold growth, rust on tools, wood rot, and costly damage to stored items. A well-installed garage door bottom seal and threshold system using EPDM rubber and aluminum thresholds can direct water away effectively.
Energy Efficiency Enhancement
Unsealed garage doors allow hot air to enter and cool air to escape, making your HVAC system work harder. This not only increases your energy bills but also reduces indoor comfort. Proper weatherproofing with foam tape, silicone caulk, door trim seals, and thermal barriers improves insulation. Sealing your garage helps maintain a more consistent indoor temperature and supports DOE and ASHRAE energy efficiency standards.
Pest and Rodent Control
Tiny pests like ants, spiders, and mice can enter through gaps in a loose door sweep or deteriorated foam seal. Plano’s warm climate can make garages inviting to these unwanted guests. Magnetic door strips and rubber door strips help block entry points. Ensuring your door sweep kit is snug and secure can prevent pest infestations before they start.
Structural Longevity
Exposing garage interiors to constant temperature swings, moisture, and dust accelerates deterioration. Components like drywall, flooring, and even electrical systems suffer. Sealing gaps with adhesive door seals and applying window caulking or silicone sealant can extend the life of your garage.
How to Inspect Your Weather Sealing
Conducting a thorough seal inspection before the summer season is crucial. Here’s a detailed step-by-step guide that walks you through evaluating your current garage door weatherproofing.
Step 1: Visual and Manual Inspection of Bottom Seal
Check your garage door bottom seal for visible signs of wear, such as cracks, brittleness, or compression. If you can slide a utility knife underneath the seal easily or see light when the door is closed, it likely needs replacing. EPDM rubber is more durable and heat-resistant compared to vinyl and is the preferred material for Plano’s climate.
Step 2: Assess Side Seals and Top Trim
Inspect the side seal and door trim seal for looseness or detachment. Run your hand along the edges to feel for gaps or drafts. If the foam tape or vinyl sweep is hardened or deteriorated, it should be replaced. You can also use a heat gun to test for airflow entering through the seals.
Step 3: Check Threshold and Floor Seal
Look at the floor for signs of water staining or dirt lines near the threshold. If water consistently enters despite a closed door, your aluminum threshold may be worn, or the sealant around it could be compromised. Reapplying installation adhesive with a caulking gun can improve the seal.
Step 4: Evaluate for Drafts and Temperature Swings
On a windy day, stand inside your closed garage. If you feel cold or warm air seeping in, it’s a sign of a compromised air barrier. Consider installing a draft stopper or upgrading to high-performance door sweep kits.
Step 5: Look for Mold or Condensation
Any visible mold, mildew, or moisture buildup inside your garage may indicate seal failure. Condensation prevention begins with identifying where leaks or air exchange are occurring and resealing those areas.
Common Weather Sealing Problems in Plano Homes
Our technicians at Rayburn Garage Doors Co. frequently encounter several weather sealing issues across homes and businesses in Plano.
Cracked or Brittle Garage Door Bottom Seals
Heat exposure causes vinyl and rubber seals to dry out and crack. These cracked seals allow water, dirt, and air to pass through freely. We recommend seasonal replacement with EPDM rubber for enhanced durability.
Loose Door Sweeps or Misaligned Doors
A loose door sweep can occur due to repeated door use or improper installation. When door sweeps detach or shift, they no longer provide adequate coverage. Door sweep kits and vinyl trim can solve this issue.
Ineffective DIY Sealing Attempts
Many homeowners attempt to fix seals using basic foam weatherstrip tape or glue-on rubber strips without proper tools like measuring tape, miter shears, and sealant guns. These quick fixes often fail when exposed to heavy rain or high temperatures. Professional installation ensures a secure and long-lasting fit.
Aged Weatherproofing Materials
Older homes in Plano often have outdated door weather stripping or sponge-type materials that lack durability. Upgrading to modern solutions like magnetic door strips, silicone caulk, and high-grade foam seals can greatly improve performance.
Choosing the Right Materials for Weather Sealing
Selecting the proper weather sealing materials based on climate, usage, and garage type is essential.
| Seal Type | Ideal Application | Materials | Estimated Replacement Cycle |
| Garage Door Bottom Seal | Prevents water entry and drafts | EPDM rubber, vinyl | Every 2 to 3 years |
| Threshold Seal | Secondary floor-level protection | Heavy-duty vinyl, aluminum threshold | 3 to 5 years |
| Side and Top Seals | Stops wind and pests | Foam tape, vinyl trim, door trim seal | 4 to 6 years |
| Door Sweep | Under-door air control | Vinyl sweep, rubber door strip | 2 to 4 years |
| Brush Seal | Commercial and uneven floors | Nylon or polypropylene | 3 to 5 years |
We often recommend Energy Star-rated products and sealing systems compliant with the International Code Council to maximize energy savings and weather resistance.
Should You Repair or Replace Your Garage Seals?
Knowing whether to repair or replace your weather sealing depends on the severity of deterioration and your long-term goals.
You should replace your seals if you observe the following:
- Visible damage such as tears, cracks, or missing sections
- Brittle or compressed seals that no longer rebound
- Frequent water infiltration or pest problems
Consider a repair if:
- Minor sections have peeled or shifted, but are still intact
- You need a quick fix before an upcoming storm
An upgrade is ideal when your current sealing lacks insulation properties or you want to improve garage energy efficiency. In such cases, pairing a garage door bottom seal with foam weatherstrip tape, vinyl sweep, and window insulation film creates a comprehensive barrier.
The Cost of Neglecting Garage Weather Sealing
Failing to maintain or inspect your garage door seals can lead to substantial expenses.
- Water damage repairs can range from $500 to over $2,000.
- Mold remediation often exceeds $1,500.
- Increased utility costs due to energy inefficiency can add up to 20 percent or more to your annual bills.
- Replacing a warped or damaged garage door may cost $1,200 or more.
- Pest control visits range between $150 and $300.
Investing in professional garage weatherproofing using durable materials and expert installation saves money over time and protects your home.

Frequently Asked Questions (FAQs)
1. Can I weather seal my garage door if it’s uneven or sits on a sloped driveway?
Yes, you can still weather-seal an uneven garage door or one that rests on a sloped surface. In such cases, using an adjustable or beveled threshold seal along with a flexible EPDM rubber bottom seal works best. Custom-fitted door sweeps and brush seals can also be tailored to accommodate irregular floor levels.
2. How long does it take to replace all garage door seals professionally?
A professional technician can usually replace all garage door seals in 1 to 2 hours, depending on the size of the door and the extent of deterioration. This includes removal of old material, surface prep, and installation of new seals. Complex commercial doors or those with damage may require additional time.
3. Will weather sealing reduce outside noise coming into the garage?
Yes, properly installed weather seals can help reduce external noise by creating a tighter barrier around the garage door. Using foam seals, rubber strips, and insulated door sweeps can significantly dampen sound. However, for maximum soundproofing, additional garage door insulation may be required.
4. Is there a difference between garage door insulation and weather sealing?
Yes, garage door insulation focuses on temperature regulation by using materials like foam boards or reflective panels, while weather sealing blocks external elements like water, air, and pests. Both work together to improve energy efficiency and comfort. For best results, use insulation along with high-quality weather stripping.
