Owning a home in Houston, Texas is different than living in another part of the country because of this state’s seasonal cycles and climates. One year, Houston residents will receive extremely cold winters followed by the hottest of summers, while the next year they may be welcomed by a cool, wet Summer season. As a foundation repair company in Houston, TX, we know these cycles very well.

This inconsistency leads to the soil’s moisture content to change drastically, and this can greatly impact the foundation of your home. The soil will expand and contract, leading to damage in home foundations that can be expensive to repair. Consider a wire that has been bent too many times – this is how it works.

Of course, engineers have worked toward developing foundations that consider this large problem, but this doesn’t mean your home won’t experience foundation issues such as:

  • Cracks
  • Jammed doors/windows
  • Sloping floors
  • Protruding nail heads from walls
  • Drainage or plumbing problems

Prior to moving into a house, you probably will take these factors into consideration. However, sometimes these damages cannot be foreseen and may creep up over the years. There are so many different variables that can lead to foundation failure. In this post, we want to cover how to repair foundation cracks from outside the home.

Fixing Foundation Cracks From the Outside: How to Patch Minor Cracks

Not only can these issues be stressful, but they may lead to larger problems when left untreated. Your home is most likely your biggest asset, so it’s important to protect your investment as best you can.

Wondering how to repair foundation cracks from outside? For small cracks, you can patch them yourself by gathering the right tools and following these steps:

  1. Inspect the area
  2. Prepare the crack for repair
  3. Begin by repairing hairline cracks
  4. Repair larger cracks
  5. Seal the foundation walls

The Supplies You’ll Need to Repair Cracked Foundation Outside

This process does take some learning, and it’s something you want to research thoroughly if you’ve never done it. Begin by acquiring all needed supplies – even for the smallest of cracks, supply lists can be extensive.

A few items you need to gather include but are not limited to:

  • Hammer
  • Dust mask
  • Air compressor
  • Patching compound
  • Putty knife
  • Cement mix
  • Caulking gun

The repair of small cracks makes for a great DIY project. However, for larger issues signaling damage such as doors or windows sticking from house settling, you may need to get in touch with a structural engineer to assess your foundation. Leaving this matter unattended can lead to bigger, costlier foundation issues down the road.

Outside Foundation Crack Repair

What about how to repair cracks in concrete foundation walls? For these projects, you’ll mainly just need cement, gravel, sand, and water.

The only downfall of completing these repairs yourself is that when the water evaporates, the other ingredients in the mix will cure into a hard slab. The curing process sometimes results in hairline cracks. Note, additional materials will be required if you are dealing with cracks during stucco maintenance.
