Why does it matter?
When a home suffers from subsidence, an immense amount of force is being exerted onto the structure. This force strains the footings, floors, walls, ceiling and even the roof.
If subsidence isn’t stopped, structural issues like wall cracks can multiply, making your home unsafe for occupancy.

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.
