Underpinning strengthens and stabilises foundations that have shifted, sunk or become damaged
over time. Common signs include cracked walls, sticking doors, uneven floors and visible
foundation damage. Specialist underpinning contractors can assess your property and implement
the right solution to secure your home. Post your job on The Quote Yard to compare quotes.

Underpinning FAQs
What are the signs I need underpinning?
Common warning signs include cracks in walls (especially diagonal cracks from door/window
corners), doors and windows that stick or won't close properly, uneven or sloping floors,
gaps between walls and ceilings, and visible cracks in the foundation itself.
What causes foundation problems?
Foundation issues are commonly caused by reactive clay soils that expand and contract with
moisture changes, poor drainage, tree roots, inadequate original foundations, plumbing leaks,
or changes to the water table. A professional assessment will identify the specific cause.
What's the difference between underpinning methods?
Traditional concrete underpinning involves excavating beneath the existing foundation and
pouring new concrete sections. Resin injection is less invasive, using expanding polymer
injected through small holes to stabilise and lift the foundation. The best method depends
on your specific situation.
Can I stay in my home during underpinning?
In most cases, yes. Resin injection is minimally disruptive and you can remain in the home.
Traditional underpinning may cause more disruption but typically doesn't require you to
move out. Your contractor will advise based on the scope of work required.
