Bottom seals on garage doors

 Bottom seals on garage doors are an important component that helps provide a barrier against external elements, such as dust, drafts, insects, and water. They are designed to seal the gap between the bottom of the garage door and the floor, preventing unwanted elements from entering the garage and ensuring energy efficiency.

Here are some key points about bottom seals on garage doors:

  1. Types of Bottom Seals: Garage doors typically use one of the following types of bottom seals:

    • Threshold Seals: These are rigid strips made of durable materials like aluminum or vinyl. They are installed directly on the floor in front of the garage door, creating a seal when the door is closed.
    • Retainer and Seal Combination: This type of bottom seal involves a flexible seal attached to a metal or PVC retainer. The retainer is installed on the bottom edge of the garage door, while the seal extends down to contact the floor when the door is closed.
    • Bulb Seals: Bulb seals consist of a flexible bulb-shaped seal attached to a retainer strip. The retainer is installed on the bottom edge of the door, and the bulb seal compresses against the floor when the door is closed.

  2. Function and Benefits: The primary function of a bottom seal is to provide a weather-tight seal between the garage door and the floor. Some benefits of properly installed bottom seals include:

    • Protection against drafts: Bottom seals help prevent drafts from entering the garage, thereby improving energy efficiency and reducing heating or cooling costs.
    • Keeping out debris and pests: They help keep dust, leaves, insects, and small animals from entering the garage.
    • Moisture barrier: Bottom seals help prevent water or rain from seeping into the garage, keeping the interior dry and preventing water damage to stored items.
    • Noise reduction: A good bottom seal can help reduce noise transmission, blocking out some of the external sounds.

  3. Installation and Maintenance: Installing a bottom seal typically involves attaching the appropriate retainer to the bottom edge of the garage door and then fastening the seal to the retainer. Threshold seals are installed directly on the floor in front of the garage door. It's important to ensure proper alignment and sufficient compression for an effective seal. Regular inspection and maintenance are recommended to check for wear, damage, or deterioration. If the bottom seal becomes worn or damaged, it should be replaced to maintain its effectiveness.

It's worth noting that different garage doors may have specific bottom seal requirements, so it's best to consult the manufacturer's instructions or seek professional advice to ensure the correct type and installation method for your specific door.

When changing a broken garage door spring should i change both?

Image
  Yes, it's generally recommended to change both garage door springs when one of them breaks. Here's why: Balance: Garage doors are designed to operate with a balanced spring system . When one spring breaks, the balance is disrupted, and the remaining spring will have to bear the entire weight of the door. This can put extra stress on the working spring and lead to its premature failure as well. Symmetry: Having two springs ensures even torque force distribution on both sides of the garage door tube. This helps prevent unnecessary strain on components like the end bearing plates. Safety: A balanced spring system contributes to the safe operation of the garage door. When both springs are functioning correctly, the door is less likely to become misaligned or suddenly drop, reducing the risk of accidents or injuries. Cost Efficiency: Replacing both springs at the same time can be more cost-effective in the long run. If you replace only one spring and the other one fails shortl...
