Why Corona Properties Face Unique Remediation Challenges
Known as the “Circle City” for its unique circular Grand Boulevard, Corona was founded in 1886 at the height of Southern California’s citrus boom and incorporated in 1896. Once the “Lemon Capital of the World,” the city transformed during the 1980s and 1990s into one of the Inland Empire’s fastest-growing communities. Today, over 157,000 residents call Corona home, enjoying neighborhoods like Dos Lagos, Sierra Del Oro, Corona Hills, South Corona, Eagle Glen, Corona Ranch, Sycamore Creek, Trilogy at Glen Ivy, Downtown Corona, and The Retreat. The city is bordered by Norco and Riverside to the north and northeast, Eastvale to the north, Chino Hills and Yorba Linda to the northwest, and the Cleveland National Forest and Santa Ana Mountains to the southwest.
Corona’s Mediterranean climate brings mild, wet winters and hot, dry summers. Temperatures typically range from the mid-40s to mid-60s in winter to the upper 80s and low 90s in summer, with the city enjoying approximately 280 sunny days per year. The rainy season spans November through March, delivering most of the area’s 10–14 inches of annual rainfall. As an inland city, Corona experiences lower humidity than coastal areas—averaging around 48–60% depending on the season—with May often reaching higher humidity levels during the spring transition.
This combination of seasonal rain and moderate humidity creates specific challenges for Corona homeowners. The median construction year for Corona homes is 1991, meaning most properties were built during the city’s housing boom of the 1980s, 1990s, and 2000s. These homes typically feature stucco exteriors and tiled roofs common to Southern California construction. While well-built, many of these homes are now 25–40+ years old, meaning plumbing systems, water heaters, and roofing materials are reaching the end of their expected lifespan. When winter storms deliver concentrated rainfall after months of dry conditions, aging infrastructure can fail unexpectedly. Water intrusion combined with the area’s temperature swings means mold can begin growing within 24–48 hours if moisture isn’t addressed quickly.

Mold Testing in Corona
Not sure if you have a mold problem? Musty odors, unexplained allergies, or past water damage are all reasons to test. Our Mold Testing specialists collect air and surface samples, work with accredited labs, and explain exactly what the results mean for your property.
Asbestos Removal in Corona
Most Corona homes were built in the 1980s and 1990s, after asbestos use in construction declined significantly following the 1978 regulations. However, some older structures from the city’s earlier citrus era, commercial buildings, and materials used in renovations of older properties may still contain asbestos. If you’re planning work on any property with uncertain material history, professional testing before you start is the safe approach. Our licensed asbestos professionals provide testing and safe abatement following all federal, state, and local regulations.

Why Choose MoldRx for Home Remediation in Corona?
MoldRx started at a dinner table—not a boardroom. Two neighbors, one with over 20 years in mold remediation and the other with decades in digital marketing, kept coming back to the same problem: property owners had no reliable way to know who they could trust. Too many contractors compete for attention, but there’s no clear way to tell who actually knows what they’re doing. MoldRx was built to solve that problem.
We’re a family and friend owned and operated business, and we run it the way we’d want to be treated if we were the ones calling for help. That means honest information from the first conversation—not a scripted sales pitch.

What makes Corona homes prone to mold issues?
Corona’s climate brings concentrated rainfall from November through March, followed by hot, dry summers. When water intrusion occurs—whether from roof leaks, plumbing failures, or appliance malfunctions—the moisture combined with Corona’s warm temperatures creates conditions where mold can take hold quickly. Most Corona homes were built between the 1980s and early 2000s, meaning plumbing, roofing, and water heaters in these properties are now 25–40+ years old. Hidden leaks behind walls or under slab foundations can go undetected until mold growth is already established. The proximity to the Santa Ana Mountains also means Santa Ana wind events can cause sudden temperature and humidity changes that stress building materials.
Do most Corona homes contain asbestos?
Most Corona homes were built in the 1980s and 1990s, after the 1978 regulations that significantly reduced asbestos use in construction. This means the majority of Corona’s housing stock has minimal asbestos concerns. However, some older structures from the city’s earlier citrus and oil era, commercial buildings, and materials used during renovations may still contain asbestos. If you’re planning work on any property with uncertain material history—especially pre-1980 construction—professional testing before you start is the safe approach.
What are common causes of water damage in Corona?
The most common causes we see in Corona include aging water heaters and appliances reaching end of life, plumbing failures in homes that are 25–40 years old, roof leaks during winter storms, and condensation issues in poorly ventilated areas. Slab leaks—particularly common in Southern California slab-on-grade construction—are another frequent issue. Corona’s location near the Santa Ana Mountains can also contribute to drainage problems around foundations during heavy rain events, and the sudden temperature swings during Santa Ana wind conditions can stress pipe joints and roofing materials.
How do I know if I need mold testing in Corona?
Consider professional mold testing if you notice persistent musty odors without visible mold, experience allergy-like symptoms that improve when you leave home, have had past water damage that may not have been fully dried, or are buying or selling a home and want documentation of indoor air quality. Testing is also essential after remediation to verify the work was successful.
Does MoldRx serve commercial properties in Corona?
Yes. Our vetted professionals handle residential, commercial, and multi-family properties throughout Corona—from single-family homes in Dos Lagos to office buildings near the SR-91/I-15 interchange and retail spaces in Downtown Corona or at The Shops at Dos Lagos. We understand that commercial properties have different requirements, including faster timelines and documentation for liability purposes.
What should I do while waiting for a water damage professional to arrive?
If it’s safe to do so, stop the water source by shutting off the main valve or turning off the appliance. Turn off electricity to affected areas if water is near outlets. Move valuable items away from standing water. Open windows for ventilation if weather permits. Don’t use household vacuums on standing water—they’re not designed for it. Most importantly, don’t wait to call. The sooner extraction and drying begin, the less damage you’ll face.
How does MoldRx coordinate services in Corona?
When you call MoldRx, you’ll talk to a real person who listens to your situation and coordinates the right vetted professional for your specific needs. We don’t operate a call center or use scripted responses.
