About Royal Environmental Solutions
Who We Are
Royal Environmental Solutions is an environmental testing company based in Corona, CA. We
inspect homes, rental units, offices, and commercial buildings for asbestos, mold, lead,
bacteria, radon, and indoor air quality concerns, and we provide post-remediation and
clearance testing after cleanup work.
We collect samples on site and send them to an accredited independent laboratory for
analysis, then walk you through the results in plain language. Because we test and don’t do
removal or remediation, our results stay unbiased.
We work with homeowners, property managers, contractors, remediation companies, and
insurance claims across Riverside, Orange, and San Bernardino Counties.

Asbestos
Asbestos Inspection & Testing
Before you remodel, demolish, or disturb older building materials, an asbestos inspection tells you
what’s safe to touch. We inspect suspect materials such as flooring, popcorn ceilings, drywall texture,
and pipe insulation, collect samples, and send them to an accredited independent lab. You get a written
report showing which materials contain asbestos so you and your contractor can plan the work.
Good for: kitchen and bathroom remodels, demolition, property purchases, contractor or permit
requirements.
Comprehensive Asbestos Assessment
A full inspection of the whole property or project area to identify every material that may contain asbestos. We sample all suspect materials and send them to an accredited independent lab, and you get one complete report for planning remodels, demolition, or a property sale.
Good for: whole-home remodels, demolition, property purchases, contractor and permit requirements.
Visual Asbestos Assessment
A walk-through to spot materials that may contain asbestos and note their condition, without sampling.
It’s a quick way to know what you’re dealing with before deciding whether full testing is needed. You get
a summary of suspect materials and our recommended next steps.
Good for: early project planning, home buyers wanting a first look, damaged or crumbling materials.
Limited Asbestos Assessment
Asbestos testing focused on one area or a few specific materials instead of the whole property. Useful when only one room or one material will be disturbed. We sample just what matters for your project and report the lab results for those materials.
Good for: a single-room remodel, one ceiling or floor, a repair in one spot.
Asbestos Project Monitoring
During asbestos abatement or removal, we monitor the work area and collect air samples to help
confirm the work is being done safely and fibers aren’t spreading beyond the containment. The samples
are analyzed by an accredited independent lab, and we keep you updated as the project moves along.
You get independent documentation of air conditions during the job, which is useful for property
owners, managers, and contractors.
Good for: asbestos abatement and removal projects, occupied buildings during removal work, property
managers and building owners who want independent oversight.
Asbestos Clearance Testing
After asbestos removal, clearance testing confirms the work area is ready to reopen. We do a visual
check and collect air samples, which are analyzed by an accredited independent lab. You get documentation that the area passed (or what still needs attention) before rebuilding or moving back in.
Good for: after abatement, before reconstruction, contractor and property-manager documentation.
Mold & Moisture
Mold Inspection & Testing
If you see or smell mold, or have had a leak, a mold inspection finds where it is and how much there is.
We inspect for visible growth and moisture, and collect air or surface samples for analysis by an
accredited independent lab. You get a clear report with results and recommendations to help you
decide on next steps.
Good for: musty odors, past leaks or floods, allergy or breathing concerns, buying or renting a home.
Visual Suspect Fungal Growth & Moisture Assessment
A visual inspection to identify possible mold (fungal) growth and moisture problems such as leaks,
staining, or damp materials, without lab sampling. It’s a fast way to find problem areas and decide
whether testing is needed. You get a summary of what we found and suggested next steps.
Good for: water stains, small leaks, a quick check before deciding on testing.
Limited Mold Assessment
Mold testing focused on one specific area or concern, such as a single bathroom, closet, or wall, instead
of the whole property. We inspect and sample just that area, and samples go to an accredited
independent lab. You get results for the area that matters to you.
Good for: one room with a smell or stain, a single leak, landlord/tenant questions about one area.
Lead
Lead Inspection & Testing
Lead-based paint was common in homes built before 1978, and disturbing it during repairs can create
hazardous dust. We test paint and other surfaces for lead and send samples to an accredited
independent lab when lab analysis is needed. You get a report showing where lead was found so you
can plan safe repairs or renovations.
Good for: pre-1978 homes, renovations, families with young children, rental properties.
Limited Lead Assessment
Lead testing for a specific area or set of surfaces instead of the whole property. It’s a good fit when only
part of the home will be worked on. You get results for the surfaces tested so you know whether lead-
safe work practices are needed there.
Good for: repainting one room, replacing windows or doors, a single repair area.
Bacteria & Water Damage
Category 2 (Gray Water) Post-Remediation Verification Inspection
Gray water is water with some contamination, such as an appliance or washing-machine overflow. After
the cleanup, we inspect and sample the affected area to check that it was properly cleaned, and an
accredited independent lab analyzes the samples. You get independent documentation that the area is
ready to rebuild, or what still needs attention.
Good for: after gray-water cleanup, before putting walls and flooring back, insurance documentation.
Category 3 (Black Water/Sewage) Post-Remediation Verification Inspection
Black water (Category 3) is heavily contaminated water, such as a sewage backup, a toilet overflow with
waste, or floodwater. After remediation, we inspect and sample the area to confirm the cleanup worked,
using an accredited independent lab for analysis. You get clear documentation before the space is
rebuilt or reoccupied.
Good for: sewage backups, toilet overflows, flood cleanup, insurance claims.
Bacteria Post-Remediation Verification Inspection
After a bacteria cleanup, this inspection checks that surfaces and the area were properly cleaned. We
collect samples for analysis by an accredited independent lab and report the results in plain language.
You get independent proof that the area is ready, or what still needs attention.
Good for: after water-damage or sewage cleanup, before rebuilding, contractor and insurance records.
Visual Bacteria Assessment
A visual inspection of an area where bacterial contamination is suspected, such as after a leak or backup,
without lab sampling. We look for signs of contamination and conditions that support bacterial growth.
You get a summary and our recommendation on whether testing or professional cleaning is needed.
Good for: recent leaks or backups, a first look before calling a remediation company.
Limited Bacteria Assessment
Bacteria testing focused on one area or concern, such as a single room affected by a leak. We sample
just that area, and samples go to an accredited independent lab. You get results for the area in question
without paying to test the whole property.
Good for: one affected room, a single fixture or surface, a quick check after a small backup.
Air Quality & Radon
Indoor Air Quality (IAQ) Testing
If your home or workplace feels stuffy, smells off, or people feel sick indoors, IAQ testing helps find out
why. We assess the space and collect air samples for analysis by an accredited independent lab,
depending on your concern. You get results and practical recommendations to improve your indoor air.
Good for: odors, headaches or allergy symptoms indoors, new or renovated buildings, workplace
complaints.
Respirable Particulate Monitoring
This measures fine airborne dust particles small enough to reach deep into the lungs. It’s often used
during construction, demolition, or remediation, or when there are dust concerns in a workplace or
home. You get monitoring results that show whether dust levels are a concern.
Good for: construction and demolition near occupied spaces, remediation projects, dusty workplaces.
Radon Testing
Radon is a natural, odorless radioactive gas that can build up indoors. Testing is the only way to know
your home’s or building’s level. We set up the test, and results come from an accredited independent
lab, so you know whether action is recommended.
Good for: home purchases, basements and lower floors, peace of mind for families.
Clearance & Post-Remediation Verification
Post-Remediation Verification & Clearance Testing
After any mold, asbestos, or bacteria cleanup, this independent check confirms the job was done right
before you rebuild or move back in. We inspect the area and collect samples for analysis by an
accredited independent lab. You get documentation you can share with your contractor, property
manager, or insurance company.
Good for: end of remediation projects, before reconstruction, insurance and landlord documentation.
Mold Post-Remediation Verification Inspection
After mold removal, we inspect the work area and collect samples to confirm the mold problem was
properly addressed. Samples go to an accredited independent lab, and we explain the results clearly.

written report you can share with your insurance adjuster or contractor.
Good for: water damage, sewage backups, insurance claims, urgent landlord or tenant situations.
Third-Party Environmental Testing
Independent testing by a company that isn’t doing the removal or cleanup work, so results aren’t
influenced by who gets paid for the repair. We inspect, sample, and report objectively, with samples
analyzed by an accredited independent lab. You get unbiased results to share with contractors, insurers,
buyers, or tenants.
Good for: second opinions, disputes, verifying a contractor’s work, real-estate transactions.
FAQ
Do you analyze the samples yourselves?
No. We collect samples on site and send them to an accredited independent laboratory for analysis.
Then we review the results with you and explain what they mean in plain language.
What areas do you serve?
We’re based in Corona and serve Riverside, Orange, and San Bernardino Counties, including Irvine,
Anaheim, Santa Ana, Huntington Beach, Riverside, Fontana, Ontario, Rancho Cucamonga, and more. Call
(909) 325-5915 to confirm your city.
What’s the difference between a visual, limited, and full assessment?
A visual assessment is a walk-through to spot suspect materials or problem areas, without lab samples.
A limited assessment tests one specific area or material. A full inspection covers the whole property or
project area. We’ll help you choose the right one when you call.
What is post-remediation verification, and why do I need it?
It’s an independent inspection and testing after mold, asbestos, or bacteria cleanup to confirm the work
was done properly before you rebuild or move back in. It gives you documentation you can share with
your contractor, landlord, or insurance company.
Do I need asbestos or lead testing before a remodel?
If your project will disturb older building materials such as flooring, ceilings, drywall, or painted surfaces,
testing first tells you whether special precautions are needed. Lead paint is a common concern in homes
built before 1978. Your contractor or local agency can tell you what’s required for your specific project,
and we can provide the testing.
How much does testing cost, and how long do results take?
Cost depends on the type of testing, the size of the area, and the number of samples, so call (909) 325-
5915 for a quote. Results are available same day, in 24 hours, or in 48 hours, depending on the test.
