Interior & Exterior Cracked Wall Repair Services

Cracked walls are often the first warning signs of serious and ongoing structural damage caused by subsidence. Cracks forming in walls is not an uncommon occurrence, but where some of them can be relatively harmless, others may be a sign that the foundations are sinking or have been damaged. If these problematic cracks aren’t taken care of as soon as possible, then it could cause further damage, therefore decreasing the value of your property.

When are cracks in walls signs of a problem with the structure itself?

If you’re experiencing larger cracks in the wall, and if that you start to notice the following characteristics, then the foundations of the building may have been weakened:

· The two sides of a wall are at different heights

· There is a gap between doors and windows and their frames

· Any cracks are wider than about 5mm

Cracks on walls that may be problematic usually originate around windows, doorways or the corners of buildings. Generally, smaller cracks in walls, that are hairline in nature, are harmless. The appearances of these cracks are commonly due to seasonal expansions and the contraction of soils beneath the building that takes place over time. Hairline cracks can be easily patched and re-painted, making it a relatively easy and inexpensive issue to rectify.

Why do larger cracks appear in walls?

Large cracks in walls may appear when the foundation of a building shrinks or becomes weakened, allowing the entire building, or even a section of it, to sink downwards – known as subsidence. This usually occurs when the soil beneath the building has become either too dry or too wet.

Likely causes of subsidence include:

· Shrinking clay caused by dry spells

· Excessive water due to broken pipes

· Floods/flooding

· Fillings that have been compacted poorly

· Tree roots drawing water from the soil – caused by thirsty trees in dry weather
