The front porch is the first thing people see as they approach your home. It sets the tone for the quality of artistry and durability to expect from your home as a whole. So if you want to keep visitors admiring your home’s beauty, make sure the front porch doesn’t let down those high expectations.

Step One: Inspection and Preparation

Before doing anything with your sinking porch, take time to inspect it thoroughly and prepare by gathering up the right tools and materials needed to complete all necessary repairs. Also, note that what causes porches to sink could vary depending on different factors such as weather conditions, soil type, and the weight of people or objects often standing or walking on it. So be sure to take all this into account when trying to diagnose the problem.

Step Two: Add Support

One common reason a porch might sink is that the foundation or supports are weak or rotted. In this case, you’ll need to add new support beams or columns underneath the porch to lift it back up to its original level. Of course, you could do this by yourself, but it will be a lot easier if you have someone to help you.

If your porch is uneven, then you’ll need to use some leveling materials such as shims, concrete, sand, or gravel to make it even again. This is especially important if there are gaps between the porch floor and the foundation, as these can cause people to trip and injure themselves.

Step Four: Repairing the Floor and Railing

If the floor or railing of your front porch is damaged or rotted, then you’ll need to repair or replace it before fixing the sinking issue. Again, be sure to use sturdy materials that can withstand weather conditions and normal wear and tear.

Step Five: Re-Staining or Painting the Porch

A fresh coat of paint or stain can do wonders in hiding any imperfections or damage on your porch, so this might be something worth considering after completing all other repairs. Choose a color that will compliment your home’s exterior, and be sure to use a good quality paint or sealant to protect the new finish from the elements.

With these simple steps, you should be able to fix your sinking front porch in no time! And if you’re still not sure how to proceed, it might be best to consult with a professional contractor who can help guide you through the entire process.

Precautions While Fixing a Sinking Front Porch

  • Ensure that the ground is level. If not, you will need to build up underneath one of the legs on each side of the porch and pour new cement for the proper foundation for your patio.
  • Do not start working on a sinking front porch if it is raining or if there is evidence of any moisture in the soil or sidewalk below your patio. The dirt and concrete may be moist and could further damage your porch as you try to lift it with shims and jack posts.
  • When lifting your front porch with jacks, ensure that no one stands under it while you are using those tools. You don’t want anything falling on anyone’s head! Likewise, never put someone in charge of keeping people away from the porch while working on it if they are not comfortable or experienced with doing so.
  • If you do not feel comfortable lifting your porch with jacks and shims, or if there is a lot of weight to move, it is best to call in a professional. Trying to fix a sinking front porch without the proper experience or tools can further damage the patio or even injury.

Why Does Front Proches Sink?

Front porches can be several reasons, but the main culprit is often poor soil drainage. If rain or snowmelt accumulates around the foundation of your house, the added weight will cause the porch to sink. Other causes of sinking porches can include:

Poorly compacted soil

If the soil is not compacted well around your porch, it can shift and leave gaps that will fill with water.

Lateral pressure

When there is a high amount of snow or rain on your porch roof, this weight can add force to your porch and cause it to sink. The lateral pressure from snow alone should not cause sinking; however, heavy spring rains can happen while removing all of the snow from your porch, which sometimes leads to problems.


Your home and driveway may be affected by natural processes such as erosion and settlement that cause an uneven distribution of soil or bedrock under different parts of your foundation or porches. This could leave some areas higher than others, creating poor drainage.

Tree roots

Over time, tree roots can grow near your porch and create cracks in the soil. This damage causes water to pool next to the foundation instead of draining away, causing the patio or front steps to sink.
