Customer Question
We moved into our house...
We moved into our house 2 years ago and had several cracks patched throughout the house. Within 6 months all of them were back and some seem to be growing. The front door frame seems uneven and I had shaved the top of the bedroom door so it could close. About a month ago that same door is starting to stick again. I'm concerned that there's a structural problem but it seems concentrated in the bathroom areas. We have two bathrooms back to back in the hallway and it seems they might be sagging. We have a raised foundation. Finally, about a year ago, when it wasn't quite so bad, we had several companies come out to take a look and all three gave us different responses so we were left wondering if anyone really knew what was going on or if they were all guessing.

Do you know anything about the structure near the bathrooms?

I only know we're on a raised foundation
Customer reply replied 2 years ago
we're towards the base of a hill.
Customer reply replied 2 years ago
Do you have any thoughts or suggestions?
Structural Engineer: StructuralEng, Consultant replied 2 years ago

All wood structure? Joist size? Joist span?

Customer reply replied 2 years ago
It a rancher. I'm guessing all wood structure. I don't know joist size or span.
Customer reply replied 2 years ago
Perhaps you can suggest a list of questions I need to ask to get a good answer (like joist size/span, etc). Or whom to call to get a reliable assessment.
Structural Engineer: StructuralEng, Consultant replied 2 years ago

It sounds like a progressive problem. When did it start rubbing again? Temp and moisture increases cause swelling

Customer reply replied 2 years ago
We moved into the house in December (Southern California - so not freezing temps, but cold). We had the plaster walls patched in the spring. We do have a sprinkler system that waters close to the house and we're trying to address that and convert to a drip system. By the summer the cracks were back. I shaved the door to the bedroom in the fall and now it's sticking again (and there was no rubbing after I shaved the door).
Structural Engineer: StructuralEng, Consultant replied 2 years ago

Do you have pictures of closed doors (that rub) that you can share?

Here are four
Customer reply replied 2 years ago
Are you able to see them? Not sure if the file size is okay.

Structural Engineer: StructuralEng, Consultant replied 2 years ago

I'm looking at the pictures now.

If you want to look at the house on Google it's***** 91364
Structural Engineer: StructuralEng, Consultant replied 2 years ago

These look like cracks associated with vertical deflection of the supporting members. These are difficult to diagnose when you have access to the house. I will think on this and get back to you ASAP. It could be settlement or deflection or possibly something else

Ask Your Own Structural Engineering Question
Customer reply replied 2 years ago
Thank you. Could you briefly explain vertices deflection?
Structural Engineer: StructuralEng, Consultant replied 2 years ago

When a beam sags, that is vertical deflection. The difference in wood is that it creeps, so deflection increases over time, even if the load never increases

Customer reply replied 2 years ago
Thanks again. If you have any recommendation for next steps that would be helpful. It seems a lot of companies over the phone want to jump to settlement or hillside issues when I'd like to rule out a rotten support or some other problem.
Structural Engineer: StructuralEng, Consultant replied 2 years ago

I agree. They don't mind jumping to conclusions because you're paying for it all. Let me put some effort into this and get back to you ASAP
