It's hard to imagine, but many basements built in the past have not been built correctly. They were built by inexperienced construction workers who did not have the knowledge to properly build these houses. Since the walls of your basement support the entire house and begin to cause problems, the rest of the house begins to suffer.
Now, what can you really do and how can you solve this problem? If you have no experience in the construction industry, it is better to hire someone with the necessary experience to adequately repair the basements and basement walls.
It is not something that you should face without any experience. This would require the removal of exterior dirt, down to the basement, then remove one wall at a time after consolidating the rest of the house. adequately.
Again, do not try to do it alone. If the basement walls are burned or damaged, it is good to hire a professional for these repairs at home. The sloping walls could eventually tear down your home; therefore, you should make sure to contact a professional to evaluate at least the situation for you. Get the opinion of different people. Try to ask several professionals to look at the walls of the basement.
