Jammed doors and windows

Jammed doors and windows and house movement

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.

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:

  • Groundwater levels affect soil particles causing compression and settlement of the home’s foundation
  • Soil erosion, often caused by water that is flowing beneath a building’s foundation resulting in voids and a reduction of bearing capacity
  • 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 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

Soil stabilisation FAQ’s
What happens with unlevel driveways, floors and hardstand areas?

After the application of the Mainmark solution, unlevel surfaces will become aligned again as the ground underneath is strengthened and re-supported. Simple cosmetic repairs may be required.

Will there be a mess?

Very little, if any. We use Teretek® engineered Resin Injection technology, which is likened to “keyhole surgery”, or JOG Computer-Controlled Grouting, with no major excavation and minimal disruption or mess. The injection holes required are very small.

How long does it take?

Each project is different and depends on the required amount of lift, area for correction, building construction, and ground conditions. Most projects can be completed in a day or two, and we can work at night or on one area at a time, so your business can keep operating.

Do i need to send my workers home?

No, most projects don’t require you to vacate the premises or even move furniture or equipment. For the most part, you can keep operating as normal. Driveways can often be driven on in as little as 30 minutes after treatment.

What warranty will i get?

The materials we use have been developed for use underground and have been specifically engineered to resist shrinkage and deterioration. Teretek® is warranted by Mainmark for an industry-leading period of 50 years.

Is it safe and environmentally friendly?

Injected Teretek® and JOG materials are environmentally inert and have no detrimental effects on the environment.
