Pre-Purchase Environmental Inspection Oklahoma City
What the home inspector can't see.
You're buying a house. The home inspector checked the structure, the roof, the
HVAC. But what about what's invisible?
Mold behind walls. Lead paint under layers
of latex. Asbestos in floor tiles. Air quality issues the seller doesn't even know about.
These
problems can cost tens of thousands to fix — and they're not covered by a standard home
inspection.
I'm Derrick Fredendall. I test for the invisible hazards. You get
answers before you sign.

What Home Inspectors Don't Test
Standard home inspections are visual. Environmental issues are invisible.
Home Inspector Checks
Roof, foundation, electrical, plumbing, HVAC operation, windows, doors, structural issues. They look at what they can see.
Environmental Inspector Tests
Mold spores in air, lead in paint, asbestos in materials, air quality, water quality. We test for what you can't see.
Both are valuable — they test different things. Home inspectors may note "signs of water damage" or "possible mold." I confirm whether there's actually a problem and how severe it is.
Pre-Purchase Environmental Testing Options
Choose based on the property and your concerns.
Mold Inspection
For any home with water damage history, musty smell, or visible staining. Air samples reveal hidden contamination.
Lead Paint Testing
Required disclosure for pre-1978 homes. Testing confirms presence before you're committed.
Asbestos Testing
For pre-1980 homes, especially if you plan renovations. Floor tiles, insulation, popcorn ceilings.
Air Quality Testing
For homes near highways, industrial areas, or if occupants have allergies/asthma.
Water Testing
Essential for homes with private wells. Bacteria, nitrates, and mineral analysis.
Bundle Package
Mold + lead + asbestos screening. Comprehensive protection for older home purchases.
Why Independence Matters for Buyers
Some inspection companies also do remediation. And some remediation companies have "inspector partners" who refer work back to them.
That's a conflict of interest. If someone profits from finding problems, can you trust their assessment?
I don't remediate. I don't have referral relationships. I have no financial stake in what I find.
When I say the house is clean, you can believe it. When I say there's a problem, you know it's real — not manufactured to sell you services.
- No remediation services — ever
- No referral kickbacks from contractors
- Reports designed for negotiation leverage
- Your protection is my only job
How Pre-Purchase Testing Works
Designed to fit your inspection contingency timeline.
Your inspection contingency starts (typically 10-14 days). This is your window for all inspections.
Call me with your timeline. I can usually schedule within 2-3 days. Rush available for tight deadlines.
Testing takes 1-2 hours depending on scope. I coordinate with your agent and the listing agent for access.
Air samples return in 24-48 hours. Lead and asbestos typically 3-5 days. I'll provide estimated timelines.
Full documentation with lab results and my assessment. Use this to negotiate repairs, credits, or price reduction.
Pre-Purchase Testing Situations We See
The Musty Smell Investigation
An Edmond buyer noticed a smell during showings. Testing confirmed mold in the crawlspace. They negotiated $8,000 in remediation credits before closing.
The 1965 Renovation
A Norman buyer planned renovations on a 1965 home. Lead and asbestos testing revealed both hazards. They adjusted their renovation budget and timeline accordingly — no surprises later.
The Well Water Question
A Moore rural property had a private well. Testing found elevated nitrates from nearby agriculture. The buyer required seller to install a treatment system before closing.
The Peace of Mind Check
A Nichols Hills buyer simply wanted confirmation that their new home was clean. Testing found no issues. They moved in with confidence.
