If you have a garage, chances are that you also have at least one garage door opener. Your garage door opener is one of those things that runs day in and day out for years..until it doesn’t.
We had a lot of snow this past winter and apparently the load exceeded the design specifications of this garage roof. Or maybe deferred maintenance caught up with structure. Whatever the case, it appears this garage is near the end of it's useful life ;-).
Your home inspector saw this as I was passing by and couldn't resist stopping and taking a picture.
In the attached video of a cracked garage door top panel. I come across this defect quite often during home inspections. Improper adjustment of the garage door tracks and/or the drive chain can result in jerking of the door during operation.
Quite often during a home inspection I will note a gap between the concrete driveway and the garage slab on the inspection report. Taking the time to fill the gap will be worth the effort. Excess water under the slab will cause the slab to raise in the winter as the ground freezes. The gap can be closed using a filler/backer rod and a self leveling sealant filler material.
The first step is to clean the gap, blowing away all dust and debris. If there is any depth to the void you will need to fill it with a filler material, sometimes called backer rod, or backer rope. This is typically a closed cell synthetic material that looks like one of those float noodles that the kids use in the pool. But a size that is slightly wider than the opening you are trying to fill. Your local Rochester, or Southeastern MN building materials store will have these materials.
Next, force the backing materials into the opening using a putty knife until you have about ¾-1 inch below the concrete surface. The backer rod material will support the filler sealant and will expand and contract as the seasons change. It also provides a surface that will not stick to the filler sealant. If the filler sealant is attached to three surfaces, it may not expand and contract properly and pull away from the concrete.
After the backer rod is installed, add the self leveling concrete filler or urethane type caulk. This material will fill the void and is self leveling. This material is designed to adhere well to concrete and will expand and contract with the seasons. Always follow the manufacturers directions for installation and cure time. Proper installation will give you a great result that will keep the gap filled for years to come.
At first glance, an old leaky garage door may not seem like something that would contribute to your rising home utility bills, but just might be worth thinking about. A new, insulated garage door can reduce energy loss through the garage door by up to 71%.
Most homeowners have automatic garage door openers to save themselves and their vehicles from the extreme Southeastern MN. weather conditions. It's a great convenience and one that is often taken for granted until the day you lose all electrical power.
