Frequently Asked Questions (FAQs)

Foundation problems often show warning signs like cracks in walls, floors, or ceilings; sloping or uneven floors; doors and windows that stick or won’t close properly; and gaps between walls and ceilings. If you notice any of these issues, it’s crucial to schedule a free inspection. Addressing foundation problems early prevents further damage and costly repairs in the future.

Foundation damage can stem from a variety of factors, including soil movement, moisture fluctuations, aging foundations, and invasive tree roots. Expanding and contracting clay soils, poor drainage, or trees absorbing moisture from the ground can destabilize your home’s foundation. Our team of experts can assess the cause of your foundation issues and recommend tailored solutions to fix them.

Restumping—also known as reblocking—is the process of replacing deteriorated or damaged stumps that support your home. Over time, wooden stumps can rot due to moisture, pests, or natural wear, leading to uneven floors and structural instability. Restumping involves removing these weakened stumps and replacing them with durable concrete or steel ones. This process restores your home’s structural integrity and prevents future issues.

Underpinning strengthens or stabilizes a weakened foundation by extending its depth or width with materials like concrete or screw piles. It’s often required when homes experience severe foundation cracks, sinking floors (subsidence), or structural damage caused by shifting soils. Underpinning not only stops further damage but reinforces your home’s foundation for long-term stability.

The duration of foundation repairs depends on the severity of the damage and the service required. For example:

• Restumping generally takes 2–7 days, depending on the number of stumps replaced.
• Underpinning can take 1–2 weeks for more extensive work.
• Floor relevelling typically requires 1–3 days.
• Concrete slab jacking is often completed in just 1–2 days.
