In the competitive San Diego real estate market, a “For Sale” sign usually leads to a bidding war. Homes move fast, and buyers are eager. However, there is one four-letter word that can bring a screeching halt to even the most promising escrow: Mold.
Imagine this scenario: You are selling your home, you have accepted an offer, and you are weeks away from closing. Then, the buyer’s home inspector finds a patch of discoloration in the attic or detects high moisture readings behind the master shower. Suddenly, the deal is on life support. The buyers are spooked, demanding massive price reductions or threatening to walk away entirely.
For agents, buyers, and sellers, understanding how to handle mold discovery is critical. It does not have to be a deal-killer. With the right professional approach, mold can be treated like any other repair issue—identified, remediated, and certified clean.
The Legal Weight of Disclosure
California has some of the strictest real estate disclosure laws in the country. Sellers are legally obligated to disclose any known material facts that affect the value or desirability of the property. This explicitly includes water intrusion and mold growth.
Trying to hide the problem is a recipe for a lawsuit. Painting over a moldy wall with Kilz or bleach before an open house is not remediation; it is concealment. If the mold returns after the new owners move in (and it almost always does), they can sue for non-disclosure, potentially costing the seller tens of thousands of dollars in damages and legal fees.
Honesty, backed by professional action, is the only safe route. If you suspect mold, getting a pre-listing inspection can save you headaches later. It allows you to fix the issue on your own timeline, rather than under the pressure of a closing date. According to the California Association of Realtors, proactive disclosure and repair history are key to protecting sellers from post-closing liability.
Why a “Handyman Special” Won’t Cut It
When mold is found during an inspection, sellers often scramble to fix it as cheaply as possible. They might hire a general handyman to cut out the drywall and patch it up. While this might look good cosmetically, it rarely satisfies a savvy buyer or their mortgage lender.
Buyers want peace of mind. They want to know that the source of the moisture was fixed and that the air quality is safe for their family. A receipt from a handyman simply says “drywall patched.” It doesn’t prove the mold is gone.
This is why hiring a certified remediation company is essential for saving the deal. Professional remediation companies follow a strict protocol (S520 Standard). Once the work is done, a third-party industrial hygienist can perform a “Post-Remediation Verification” (PRV) test. This is a lab analysis of the air quality.
Passing this test generates a “Clearance Certificate.” This document is gold in a real estate transaction. It is scientific proof that the home is clean. It transforms a scary unknown into a documented, resolved issue. Nolo advises that having professional documentation of repairs is the best way to reassure jittery buyers and keep the agreed-upon sales price intact.
Protecting the Buyer’s Investment
For buyers, the discovery of mold shouldn’t necessarily mean walking away from your dream home, provided the seller is willing to remediate properly. However, it does mean you need to be vigilant.
If you are buying a “flipper” home or a property that has been vacant for a while, be suspicious of fresh paint in odd places (like the ceiling of a closet) or heavy use of air fresheners. These can be masking musty odors.
Requesting a specific mold inspection—separate from the general home inspection—is often worth the cost, especially in older San Diego neighborhoods where plumbing might be aging. If mold is found, insist that the remediation be performed by a licensed professional, not the seller themselves. You want a warranty on the work.
The Cost of “As-Is”
Sometimes, a seller will refuse to do repairs and offer the home “as-is,” perhaps with a credit to the buyer. While this can look like a financial win, buyers must be careful. The cost of mold remediation can vary wildly depending on what is found once the walls are opened up.
A $5,000 credit might seem generous until you realize the mold has eaten through the structural framing and the bathroom subfloor, requiring a $20,000 gut renovation. Getting a quote from a professional restoration company before closing—during your contingency period—ensures that the credit actually covers the cost of the work.
