2. Mortar has been ignored
Many older Redlands homes have stone or brick foundations where the stones or bricks are held together with mortar.
But the life expectancy of mortar is 25 years and under many older homes the mortar is disintegrating.
The mortar can be scraped out with your finger and in many cases the mortar pours out like sugar.
If there is a strong earthquake the foundation could collapse.
4. Animals are finding access
Some under-house entries were either not correctly installed or have deteriorated over time, and they allow critters in.
When this is the case, you can count on animals breeding, defecating and dying in your basement or crawlspace, possibly contaminating the air you and your family are breathing inside your home.
In Redlands neighborhoods, opossums, cats, rats, skunks and raccoons are common, and are often looking for dark shelter.
3. Pier posts are leaning
These posts are supposed to hold up the floor structure, but in many old Redlands homes, the posts are just sitting on rocks… tilting!
"Sometimes when I go into some homes, I just can’t believe it. I think, ‘How is this house even standing?’," Bonadiman said.
They are not secured to the rocks, not secured to the girders above them in any way.
The weight of the floor is holding them in place.
During an earthquake a house experiences lateral (or side-to-side) and uplift movement.
How could a house stay put facing a combination of out-of-plumb support posts and strong side-to-side shaking?
This two-story historic Redlands Heritage Home was being supported in part by a post that was not only not secured to anything, it was halfway perched on a rock that isn't even flat. Here's one of those instances where a contractor says, "How is this house still standing?" This is obviously not to current building code.
5. The structure is not to current code
A house’s underbelly may be rarely seen and out of mind, but it’s as important to keep up to code as plumbing, electricity and kitchen appliances.
One hundred years ago it was not customary to bolt buildings down or strengthen cripple walls (short, wood-framed walls surrounding the crawl space).
Today, a lack of bolting and unstrengthened cripple walls are Our Town’s beautiful homes’ two biggest weaknesses when it comes to sliding or toppling.
7. Mold is thriving
Plumbing leaks, water dripping in from the yard and other moisture can go unnoticed for years, creating a warm and happy environment for harmful mold to grow.
East Valley mold specialist Jace Yasser says any moisture can create a serious health hazard. He says that one of the health effects of mold exposure is severe respiratory illness.
Eradication must be handled by a professional.
