Jammed doors and windows and house movement

Jammed doors and windows are often the first signs of subsidence and foundation damage in a home. If doors or windows stick and are difficult to operate, or if they swing open on their own or have gaps around their frames, the cause of these problems should be investigated quickly by an expert.
Not only apparent in older properties, 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 severity and note any changes daily. If the problems continue for prolonged periods or worsen, this is when experts should be called in to assess the likely causes.
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 affecting soil particles
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
Foundation design during construction being flawed due to inadequate information about ground and soil conditions
Vibration caused by nearby heavy road traffic or construction activity such as drilling or piling
Trees and shrubs, particularly those close to the property’s foundation.
Some species absorb a lot of water, affecting soil moisture levels
What causes jammed windows and doors?

Mainmark’s methods for treating house foundation settlement are effective for fixing the underlying problems that cause jammed windows and doors that stick in a home.
One of Mainmark’s experts will visit your home, assess the damage, and help ascertain the likely cause. Our experienced engineers and technicians establish the appropriate non-invasive underpinning approach needed, creating a plan specific to the needs of your home and the particular signs of subsidence.

Teretek® – Resin injection underpinning alternative
Teretek® is an engineered solution for re-levelling subsided buildings that utilises a plural component, expanding polyurethane resin. The expansion force of the material results in the controlled lift of structures, with a by-product of localised bearing capacity improvement through soil densification.

JOG computer-controlled grouting underpinning alternative
JOG computer-controlled grouting uses a multi-point injection technique to insert cementitious grout materials under foundations. It can be used under commercial and residential buildings ranging from single-storey shops to high-rise structures. The injected materials have a controlled set time, which allows for the precise lifting of a structure.

The benefits of choosing Mainmark’s subsidence treatments to resolve jammed doors and windows
Our dedicated team of experts is committed to understanding your unique needs and objectives, working closely with you to develop and execute.
Fast
Our technologies have fast curing times. Treated areas can be used quickly, without the delays associated with traditional subsidence repair methods.
Environmentally inert
Our subsidence treatment technologies can help with jammed doors and windows, and we use inert materials that are non-toxic and do not leach into the environment or affect the treated area.
Non-invasive
Our solutions are surgical in nature compared to traditional methods that deal with subsidence, which can cause jammed doors and windows.
Cost-effective
Compared to traditional methods, our subsidence solutions are more cost-effective and cause minimal disruption to the area.
