Last week the construction began for interior basement waterproofing. They used jackhammers for a full day to dig out a trench around the perimeter of the basement. i could hear every word they said down there, and heard one of them say "I can't believe this house has no footer". I questioned them, and they said that it does. Later my husband asked, and they told him it does not have a footer, but not to worry, it didn't matter.
They completed the task. Dug the trench, installed the drain and gravel, then concrete. They installed the sump pump into the sink to drain to the sewer which was apparently illegal. It also blew out all of that plumbing and this week they came back to run the pump out to the downspout instead and fix the damaged plumbing.
It was a stressful week around here, I'm not sure if this started to happen right away or if it took a week, but on Monday this week I noticed very large plaster cracks, a little bit of ceiling cracking, and plaster pillowing in two second floor rooms and one first floor. On the first floor the damage is under a window. On the second its mid wall, then under and above a window and into the ceiling.
This house was built in 1930 and i know plaster is fragile. I hope that it was damaged simply from the vibrations of the jackhammers, but I fear that it's foundation damage from not having a footer. How would I be able to tell the difference? Any advice would be appreciated.
Oh boy, this could be a tough call. You may want to call a "good" and "reputable" contractor to inspect your house. By "good", I don't mean somebodies good-ol-boy cousin who built their deck last summer.
Most large contractors have engineering sources who can help assess the severity of your problem.
It may seem expensive but it may be worth the peace of mind to know that your home is still standing solid.
