How Foundation Issues Can Cause Window and Door Gaps

Your foundation is one of the most critical parts of your home. Its structural integrity affects every aspect of your finished structure.

If the ground beneath your home becomes unstable, your foundation can move or settle unevenly, leading to a variety of issues.

This article focuses on how foundation movement causes gaps in windows and doors and also discusses how a gap between a window and frame occurs.

Understanding Foundation Shifting

Foundation shifting is when your home’s foundation settles unevenly. Causes of shifting include:

  1. Soil movement: When the moisture content of the soil changes, the ground beneath your home expands and contracts. This can cause uneven pressure on your foundation, causing it to shift.
  2. Settling: Like your foundation, the soil beneath your home can settle, especially if it’s new or disturbed from recent reconstruction. This settling can cause the foundation to sink unevenly.
  3. Water damage: Excessive water can compromise the soil under your home, making it more prone to erosion and settlement. This can promote foundation shifting.
  4. Tree roots can exert enormous pressure on your foundation, causing it to shift or crack.
  5. Poor construction: A foundation built poorly or not in accordance with local soil conditions can be prone to shifting.
  6. Earthquakes: Seismic activity can cause significant damage to foundations, such as shifting and cracking.

  • An important side note: Even slight shifts in your foundation can affect your home’s structural integrity.

How a Shifting Foundation Affects Windows and Doors

A gap between window and frame: If the soil beneath your foundation becomes compacted or shifts, this can cause your foundation to sink or settle unevenly.

When this happens, your structure will also shift. This causes a misalignment, leading to gaps between your window frame and the surrounding walls and trim.

These gaps between your window and frame cause drafts and loss of cold and hot air. Leaks reduce energy efficiency and increase bills.

A gap between door and frame: Another common problem resulting from your foundation shifting is the gaps created between your door and frame. This shifting will cause a gap between the door and frame when closed.

When this misalignment occurs, it is hard to lock your door, compromising your security and safety.

The window is jammed: Another typical result of a shifting foundation is windows that won’t open smoothly, jam, or get stuck. This makes opening and closing windows difficult because they’re out of alignment.

Signs That Your Foundation is Shifting

Visible gaps: A key sign your foundation is shifting is when you see visible gaps between your window and door frames.

Additional warning signs: Other signs of foundation issues are cracks in the walls, uneven or bouncing floors, sticking windows, and doors that jam or won’t stay closed.

Solutions for Foundation-Induced Window and Door Gaps

Temporary fixes vs. permanent solutions. What is the best approach?

Temporary fixes:

  • Weather stripping applied around the edges of doors and windows to seal gaps and reduce drafts.
  • Caulk can fill small gaps between the door or window frame and the surrounding wall.
  • Shim are thin wedges of wood or plastic that can be placed between the door and frame to adjust the alignment.
  • Door and window stops can be installed to prevent them from swinging too far open or closed, reducing strain on the frame.
  • Door/window sweeps can be attached to the bottom of doors and windows to help seal gaps and prevent drafts.

When should you use these temporary fixes? The most appropriate time for these temporary fixes is while you wait for a professional to address the root cause of your issues.

Also, if you’re looking for a quick and easy way to deal with a minor alignment issue or in an emergency to prevent drafts or water infiltration until a more permanent repair can be made.

Permanent solutions:

A professional should address the root cause of a shifting foundation. Some of the permanent fixes include:

  • Foundation repair encompasses underpinning, soil stabilization, and concrete lifting.
  • Structural reinforcement: The home’s structural components may need to be reinforced to deal with the shifting—things like adding beams, columns, or bracing.
  • Door and window replacement: If your foundation shifting has caused significant damage to your door and window frames, window replacement may be the best solution.
