Common Signs of Foundation Cracks
As most of us already know, foundation cracks should be repaired as early as possible and failing to do so can prove disastrous. But what causes a foundation to crack?

1. Uneven Floors

3. Widening Gap
Another sign of foundation issue is the crack between the façade and door or windows. This could be due to a shift in the foundation. If you overlook the importance of widening gaps between the façade and your front door and windows, it may lead to further structural damage.
Termites, mold, and other microorganisms may flourish in these gaps. And it may cause damage to the property and create an allergic reaction to the inmates of the house.
4. Mold Presence

So, if you see any indications of mold in the house, it is important to find the source. By hiring a professional company, you can carry out the proper mold remediation activities and prevent its growth in the future.
5. Sagging of the Floor

Another telltale sign of foundation cracks is warped ceilings. A gap between the ceiling and the walls should also be checked by professionals and resolved soon.
Types of Foundation Crack

2. Vertical Cracks:
This type of crack is very common. It runs up the foundation and may continue to the floor or ceiling of the basement. It forms due to tension on the concrete when soil shifts or settles unevenly.
If there is overpressure exerted on the foundation, vertical cracks may form. Also, hydrostatic pressure is a common reason for vertically-formed cracks. You should think of foundation crack repair only if vertical cracks are larger than ¼ inch.
Otherwise, it should not be a concern. In fact, you can take it as a DIY project and fix the cracks using any sealant available in the market.

4. Horizontal Cracks:
If you see horizontally-shaped cracks, you should not take it lightly. Those are very serious types of crack formed due to high pressure from the soil. You should get it inspected by a professional agency and carry out foundation crack repair activity without delay.

Cracks can form in the shape of the spider web as well. It normally occurs in older homes when the foundation loses strength. It is a sign of aging in older homes which should not be a serious concern. Contact an expert to know the cause of spider-web cracks if it is wider and bigger.
