Why Chino Hills Properties Face Unique Remediation Challenges
Before Spanish colonization, the Tongva people inhabited the rolling hills that would become Chino Hills, with villages like Wapijanga serving as important points of connection between tribes. After becoming part of Rancho Santa Ana del Chino in 1841, the land was used for cattle ranching for over a century. By the 1920s, the Los Serranos Country Club had opened, and the isolated terrain attracted bootleggers during Prohibition and later artists and seekers in the 1960s. The transformation began in earnest when San Bernardino County approved the innovative Chino Hills Specific Plan in 1982, calling for master-planned villages clustered around shopping centers and parks. Development accelerated through the 1980s and early 1990s, and on December 1, 1991, Chino Hills officially incorporated as a city with a population of 42,000. Today, approximately 78,000 residents call Chino Hills home, enjoying neighborhoods like Butterfield Ranch, Rolling Ridge, Fairfield Ranch, Los Serranos, Vellano, Woodview, Gordon Ranch, Payne Ranch, and communities in the Sleepy Hollow and Carbon Canyon areas. The city is bordered by Diamond Bar and Pomona to the north, Chino to the east, Brea and Yorba Linda to the west and southwest, and Corona to the southeast.
Chino Hills’ Mediterranean climate brings hot, dry summers and mild, partly cloudy winters. Temperatures typically range from the upper 40s°F in winter to the upper 80s to low 90s°F in summer, with August highs averaging around 87-91°F and occasionally exceeding 99°F during heat waves. The city enjoys approximately 288 sunny days per year. The rainy season spans November through March, delivering most of the area’s 12-15 inches of annual rainfall—often concentrated during winter storm events. Humidity levels average between 48-60%, with May and June typically reaching the highest humidity around 60%, and November being the driest month at around 48%.
This combination of seasonal rain and moderate humidity creates specific challenges for Chino Hills homeowners. Most homes were built during the 1980s and 1990s, with the median construction year being 1990. These master-planned communities feature the village-style layouts, stucco exteriors, and tile roofs typical of Southern California’s suburban development boom. While well-designed, these homes are now 25-45 years old, meaning plumbing systems, water heaters, and roofing materials are reaching the end of their expected lifespan. The city’s hilly terrain can contribute to drainage issues around foundations during heavy rain events. Water intrusion combined with the area’s humidity means mold can begin growing within 24-48 hours if moisture isn’t addressed quickly.
Services We Offer in Chino Hills
Mold Removal in Chino Hills
Chino Hills’ concentrated winter rainfall and moderate spring humidity create conditions where mold can thrive—especially in homes with hidden moisture from aging plumbing or roof leaks. The city’s rolling terrain can cause water to pool around foundations, and many 30-40 year old homes have original ductwork where condensation and mold can develop undetected. Our vetted mold remediation specialists contain, remove, and clean affected areas while taking all necessary steps to prevent mold from returning.
Water Damage Restoration in Chino Hills
Whether it’s a burst pipe, appliance failure, or storm damage during Chino Hills’ rainy season, water spreads fast and causes more damage every hour. The city’s hillside homes face unique challenges with drainage and foundation moisture during heavy rain events. Our Water Damage Restoration professionals extract water, dry structural materials, and restore your property before secondary damage sets in.

Mold Testing in Chino Hills
Not sure if you have a mold problem? Musty odors, unexplained allergies, or past water damage are all reasons to test. Many Chino Hills homes built in the 1980s and 1990s have original HVAC systems and ductwork where mold can develop without visible signs. 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 Chino Hills
Most Chino Hills homes were built in the 1980s and 1990s, after asbestos use in construction declined significantly following 1978 regulations. However, some homes in the Los Serranos area date back to the 1960s and 1970s, when asbestos-containing materials were still common in popcorn ceilings, floor tiles, and insulation. Commercial buildings, older structures, and renovation projects involving unknown materials may also contain asbestos. Our licensed asbestos professionals provide testing and safe abatement following all federal, state, and local regulations.

Why Choose MoldRx for Home Remediation in Chino Hills?
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.

Chino Hills FAQs

Response times depend on current availability. For urgent water damage, mold, or asbestos situations, call us immediately to check availability and schedule service. We’ll be honest about timing and get a vetted professional out to you as soon as we can.
What makes Chino Hills homes prone to mold issues?
Chino Hills’ climate features concentrated winter rainfall from November through March, followed by moderate spring humidity that can reach around 60% in May and June. When heavy rain arrives, the city’s hilly terrain can cause water to pool around foundations and infiltrate homes through multiple entry points. Most Chino Hills homes are now 25-45 years old, meaning original plumbing, roofing, and HVAC systems are aging. Hidden leaks behind walls, under slab foundations, or within original ductwork can go undetected until mold growth is already established—particularly in homes where condensation issues develop in poorly ventilated areas.
Do most Chino Hills homes contain asbestos?
Most do not. With a median construction year of 1990, the majority of Chino Hills homes were built after asbestos use in construction declined significantly following 1978 regulations. However, homes in the Los Serranos area and some sections of Sleepy Hollow date back to the 1960s and 1970s, when asbestos-containing materials like popcorn ceilings, 9×9 floor tiles, and pipe insulation were commonly used. Commercial buildings and renovation materials of uncertain origin may also contain asbestos. If you’re planning work on any property built before 1980 or with unknown renovation history, professional testing before you start is the safe approach.
What are common causes of water damage in Chino Hills?
The most common causes we see in Chino Hills include aging water heaters and appliances reaching end of life in 25-45 year old homes, plumbing failures in original copper or polybutylene systems, roof leaks during concentrated winter storms, and drainage issues related to the city’s hilly terrain. Slab leaks are common throughout Southern California’s slab-on-grade construction, and Chino Hills’ rolling topography can exacerbate foundation drainage problems during heavy rain events. Many master-planned communities also have original irrigation systems that can fail and cause water intrusion near foundations.
How do I know if I need mold testing in Chino Hills?
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. Given the age of most Chino Hills homes and the prevalence of original ductwork, testing can reveal hidden issues in HVAC systems that affect indoor air quality throughout the home.
Does MoldRx serve commercial properties in Chino Hills?
Yes. Our vetted professionals handle residential, commercial, and multi-family properties throughout Chino Hills—from single-family homes in Butterfield Ranch to office buildings near The Shoppes at Chino Hills and commercial spaces along the SR-71 corridor. 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. In Chino Hills’ hillside homes, check downhill rooms and lower levels where water may have traveled. 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 Chino Hills?
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. We match your project with qualified, experienced specialists who know Chino Hills and the Chino Valley—then we make sure the job gets done right.
