Today, the many homes and buildings of Diamond Bar, California do not need to worry about wealthy landowners or shifty merchants plotting to take their land, but they do need to understand the hidden dangers of mold. Indoor air quality is important to maintaining health and quality of life and mold can severely compromise both. Mold spores are usually already present on building materials when they are installed. 

Once the spores are introduced to moisture, mold can begin to grow and cause a myriad of problems both for your health and the integrity of your building components. Your best defense against mold is to keep your Diamond Bar property dry; however, this is not always easy.

Buildings may have small leaks in plumbing within the walls or a leaky roof that go unnoticed for long periods of time. These leaks can create humid environments that remain unseen and begin to grow mold. Eventually, the mold will spread until it is apparent on some outside surface within your home such as drywall. Other common reasons mold may begin to grow is after a flooding event, which is not completely dried. Any moisture that remains on drywall, wood or other materials can contribute to mold growth. 


Bathrooms without proper ventilation are prime suspects for unseen mold within walls or under the floor. Typically, mold is also visually evident as well – growing on the paint, shower curtains, or caulking. If left to flourish, mold can contribute to many health problems.

History of Diamond Bar, California

The rich history of Southern California is reflected in the humble beginnings of Diamond Bar, California. In 1840, Governor Juan Alvarado signed a deed for 4,340 acres of land to Jose de la Luz Linares. The acreage included Brea Canyon and part of Walnut Valley. Linares named the area Rancho Los Nogales, which translates to “Ranch of the Walnut Trees.”

Linares enjoyed the beauty and tranquility of his land for a brief seven years before passing away in 1847. His wife, who was left with her husband’s debts, struck a deal with the well-known landowner, Ricardo Vejar. In exchange for a pristine portion of her late husband’s land and all of his debts, Linare’s widow received $100 in goods, and 100 heads of cattle. Within ten years, Vejar managed to secure the remaining land of Rancho Los Nogales bringing his total land holdings to over 10,000 acres and making him the fifth wealthiest landowner in the Los Angeles County area. However, Vejar’s holdings greatly diminished after California became part of the United States.

In 1860, the United States government resurveyed the land grants given by Mexico’s government officials and reduced Vejar’s total landownership down to 464 acres. That same year Southern California suffered through the great drought forcing Vejar to borrow money from two local merchants – Isaac Schlesinger and Hyman Tischler – to purchase feed for his cattle. He borrowed a total of $600 with an interest rate of eight percent per month, which resulted in Vejar owing over $28,000 by 1864. Unable to pay the exorbitant amount he owed to Tischler and Schlesinger, he was forced to give up his land to the merchants to satisfy his debt. The land changed hands many times, but the land itself changed little until the Transamerica Corporation created a master-plan for the area, which lead to the housing boom of 1960 bringing in 50,000 new residents.
