Jammed Doors / Windows


Jammed Doors and Windows

Jammed doors and windows can quite often be the first signs of subsidence and foundation damage in a home.

If doors and/or windows stick and are difficult to operate, swing open on their own or have gaps around their frames, the cause of these problems should be investigated quickly by an expert.

When to start worrying about house movement?

Not just apparent in older properties, the causes behind jammed windows and doors often occur when the soil underneath a home’s foundation starts to move or settle and can no longer support the weight of the home.

Foundation settlement can happen with a change to the soil and properties of all ages are susceptible. If you notice problems with doors and windows you should monitor the extent and note any changes daily. If it continues for prolonged periods or worsens, this is when experts should be called in to assess the likely causes for you.

What causes jammed windows and doors?

To determine the correct procedure to fix any settlement issues, the underlying problem must be identified. The most common causes of foundation settlement are:

  • Soil erosion, often caused by water that is flowing beneath a building’s foundation resulting in voids and reduction of bearing capacity.
  • Groundwater levels affects soil particles causing compression and settlement of the home’s foundation.
  • Poorly compacted soil can cause settlement
  • Foundation design during construction can be flawed due to inadequate information on ground and soil conditions which can ultimately result in foundation settlement.
  • Vibration caused by nearby construction activity such as drilling or piling, or heavy road traffic can have cause foundation ground settlement.
  • Trees and shrubs can also be a factor, particularly if they’re close to the property’s foundation. Some species absorb a lot more water, affecting the soil moisture levels.
