How do you know if your garage door needs to be replaced or if you can simply repair it? What can you do to keep your garage door running at peak efficiency?

Signs That It May Be Time to Replace Your Garage Door:

Peeling or cracked paint.

Wood garage doors will need to be refinished periodically in order to protect them from the elements. The painted or stained finish can break down over time, which causes the wood to rot. The finish can also discolor or fade due to UV exposure from the sun. If you find the wood has cracked, there are holes in your door or moisture has wicked up from the bottom, it is time to replace it.

Dents and Dings.

Steel garage doors can accumulate dents and small dings over time, which greatly detracts from the door's appearance. To help minimize unsightly dents, Clopay® garage doors are constructed with true 24, 25, or 27-gauge steel. Thicker steel lasts longer and dents less. The lower the gauge, the thicker the steel. However, a "sandwich" constructed steel garage door with two 27-gauge steel skins and a bonded insulating core will be stronger than a "steel frame" door with a single layer of 24-gauge steel.

With non-insulated garage doors you may be able to push out the dings from the inside of the doors. If you are unable to do this, you may need to replace the dented sections or the entire garage door. Clopay sells replacement sections for most models. Check with your local Clopay Dealer or Retailer for details.

Sagging or bent garage door sections.

Wood garage doors have a tendency to sag over time if they are not properly maintained. When the door is closed, you'll see large gaps under the ends of the door. If your wood garage door is sagging, we recommend replacing it. Door sections can also be damaged by an automatic opener if they are not adequately reinforced.

Rising energy bills.

Older garage doors or doors installed on new homes may not be well insulated or may not have full perimeter weatherstripping to seal out the elements. An insulated, well sealed door is especially important if you have living space above or adjacent to the garage. The insulated garage door will help keep those rooms warmer in the winter, cooler in the summer, and can also help reduce energy bills. Clopay® offers insulated garage doors with R-values up to 17.2 (R-value is a measurement of thermal efficiency of a door, or how well it insulates) Click here for an overview of our products.

Your door is excessively hard to open and close.

Garage doors have a lot of moving parts, and if your door is opened and closed frequently, many of those parts will wear out. If your garage door springs are broken or improperly tensioned, the safety of your door is compromised, and your door will not function correctly. This condition will also put additional stress on your garage door opener, causing it to break or malfunction. Here are some components to check:

  • Spring(s): Are they broken? You can test the spring tension of your door. If you have an automatic opener, close your door and pull the string on your opener to disconnect it. Then open the door halfway. If it does not remain still, your spring(s) are either broken or need to be adjusted. Do not adjust or remove standard torsion springs yourself. Contact a qualified garage door repair professional.
  • Cables: Are there any worn strips hanging loose on the sides of your garage door? Are the cables frayed? If so, they are in danger of breaking and could cause serious injury or property damage. Contact a garage door repair professional to replace the cables.
  • Rollers: Do the rollers on the ends of your door move smoothly and quietly? If not, they may require lubrication or replacement. Clopay recommends a high quality nylon roller for the smoothest and quietest operation.
  • Sections: Look for peeling or fading paint, rust or dented sections.
  • Track: Are the tracks on either side of your garage door bent or twisted? Are they securely attached to the door jambs, and the ceiling via the rear track hangers?
  • Hinges: Are the hinges that join the door sections bent or broken? If so, they should be replaced.
  • Caution: The bottom brackets on all garage doors must not be removed while the door is under tension. Clopay recommends contacting a garage door maintenance professional to replace your hinges.

How to get the most out of your new garage doors:

Painting and staining.

Wood garage doors will need to be checked every year for cracking, peeling paint or fading. Wood garage doors must be painted or stained on all sides before installation, and refinished every few years depending on the exposure and weather conditions in your area. Steel, composite or aluminum garage doors do not need to be repainted unless you want to change the color. Click here for painting instructions.

Lubricate your garage door hardware.

Lubricate door hinges, rollers (except nylon rollers), sheave bearings, torsion springs, and the lift cables at the bottom corners of the door annually with light household 3-in-1 oil.
