Solving Wall Cracks
Eliminate your Wall Crack Permanently!
Are the cracks around my home structural
What should I be looking out for?
Stepped Wall Cracks
If you have stepped cracks over 5 mm in width, it’s highly likely your house foundations are no longer stable. Stepped cracks usually indicate that a large part of your home is moving, whether due to unstable brick house foundations or shifting soil below ground.
If you can see stepped cracks, then it’s probable that there are cracked walls in other parts of your home. These cracks are definitely not just cosmetic or superficial. They should be investigated as soon as possible.
Internal and external wall cracks
If you have cracks sitting above your doors and windows, or if your wall cracks are deep enough for light to travel through, then your home is experiencing significant, damaging movement. This movement puts a lot of stress on your home’s foundations and can be caused by foundation failure, soil failure, additional loads or house extensions, or even expansion of the actual brick.
Remember, if you can see straight through a crack, your home has serious structural problems that need to be addressed.
Horizontal Wall Cracks
While stepped cracks indicate mass structural shifts, horizontal wall cracks are a tell-tale sign of localised movement in your home. These cracks are usually an indicator of a foundational failure directly beneath the cracked wall.
Sometimes, horizontal cracks will stop abruptly, which means the wall is sinking at a very specific location. However, even though these horizontal cracks are a localised issue, if they’re not quickly addressed the remainder of your structure will follow suit, sinking and breaking apart as your home’s foundations drop.
Wall Cracks in Corners
Over extended periods, clay bricks (natural product clay) will expand. Sometimes even up to several millimetres per year. Sure, this doesn’t sound like much, but over the decades it’ll all add up, creating a strong lateral force on your structure. This force drives the ends of walls into each other, causing cracks to appear in the corners of your home.
If left untreated, lateral force issues will continue to destabilise your home. Things will get worse and worse until your walls become free-standing, meaning they’re about to topple over.

Why should I fix them?
Some cracks might just be cosmetic blemishes, but others can signal a more serious structural problem.
Leaving these cracks unattended could compromise structural integrity, resulting in expensive rebuilding of walls, and reduce your home’s value. They may even be a safety concern around your family.

Buildfix and my sinking Brick wall
Buildfix were great from day one! Substantial subsidence was assessed by Dale with short notice fit in with my busy schedule. I was provided with a comprehensive quote, accepted online and given a date and time not long after. On the day Jordan and Jack arrived on time, set up, got on with the job with great results, providing me with updates and were super informative throughout the whole process. They left the site clean. Fantastic, will use these guys again.
