What Are the Biggest Red Flags  Consumers Should Look For When Hiring an  SB326 Deck Inspection Company?

Great question — SB326 inspections (balcony/deck inspections for multifamily housing in California) are a big deal, and unfortunately, not every company advertising them is legitimate. The biggest red flag consumers should watch for is:

🚩 If the company performing inspections also performs repairs.

Here’s why:

Conflict of interest – The law (SB326/SB721) was designed so that inspections are objective and not influenced by profit motives from repair work. If the same company inspects and repairs, they may be financially motivated to exaggerate problems or recommend unnecessary work.

At William Leys Waterproofing Consultants LLC we guarantee in writing that we do not have any conflicts of interest. 

🚩 Compliance issues – The statute is clear: inspections must be done by a licensed architect, structural engineer, or a qualified building inspector who is not associated with a repair contractor. If someone is offering both, they may not be following the law.


Other red flags to watch for:

🚩No license disclosure (can’t prove they’re an architect, engineer, or building inspector). Who will be inspecting? An engineer or architect, or just some random people who may not be qualified in any way shape or form.

At William Leys Waterproofing Consultants LLC we guarantee that a structural engineer that we partner with will perform the physical inspection. Some companies flirt with danger by hiring subcontractors who do the inspection, and then those companies have an engineer robo sign your report.

🚩 Low-ball pricing far below market rates — often a sign they’re using inspections as a “loss leader” to sell repair work.

This is exactly right, and that’s what they are doing. We’ve done second inspections for clients and they were very happy to learn that the repairs the other company said had to be done in an emergency basis was exaggerated.

🚩Vague or incomplete reports — a proper SB326 inspection requires documented findings, photographs, and repair recommendations (if needed).

🚩 High pressure sales tactics — pushing you to sign a repair contract right after the inspection.


👉 Bottom line: Choose an independent, inspection-only professional who has no stake in whether repairs are needed. That independence is what protects you and your HOA from unnecessary costs.

At William Leys Waterproofing Consultants, as our client, we only work in your best interests.

Bill Leys Explains Why Job Site Visits are Essential For Bidding on SB326 Inspections

While on a property in Orange county I made this short video on why we walk properties before we give an HOA a bid on their SB 326 inspection.

ASTM Standardized Water Testing Proves That Construction Defects Exist at a Condo in Los Angeles

William Leys Waterproofing Consultants LLC was recently retained by an upscale condominium complex in Los Angeles to investigate leaks from one recently repaired deck and stucco wall on one condo unit that was claimed to be leaking into an adjacent unit, causing damages to the home.

Using ASTM approved water testing methods, we set up a spray rack that sprays up to 2 hours of rain in a twenty minute period to mimic actual weather conditions.

A spray rack set up against the wall imitates rainfall against a building in an industry standard testing method. These racks are calibrated and tested to meet requirements under ASTM testing methods.

Using our methodical testing approach, we were able to prove that the wall shown in the photograph above was in fact leaking. Using litmus paper and visual observations during the methodical cyclic testing as prescribed by ASTM showed conclusively that the newly repaired wall was in fact leaking at four locations.

Litmus paper has changed color, showing that water is leaking through or past the weather resistant barrier, and water is visible on the right side of the photograph where improper laps leave the stucco wall exposed, allowing water to enter dry space.

With this proof in hand, the Association can now move ahead with correcting the deficiency and fix the interior space. Liability on the proper responsible party that created this defect can now be established and legal counsel can now move forward with making claims against the contractor and his insurance company. Without standardized ASTM testing their claim would be very difficult to support in a court room.

A Flir Thermal Imaging camera shows the path of water in blue. Thermal cameras are important to use in leak investigations as they provide secondary evidence that supports the primary evidence.

When your buildings leak, call us first to establish where the leaks are coming from and with our investigative team of water intrusion experts, we can help you determine the source of the leaks, why they leak and who is responsible for the leaks. Don’t wait or let your contractor deny responsibility, put us on your team!

You Gotta Read the Fine Print! HOA’s Need to be Careful of Companies Advertising “Free” or “20% Off” Type Offers on Balcony Inspections

Many companies are offering deals that have hidden motives behind them. Before buying, you need to know what it’s really going to end up costing your HOA.

William Leys Waterproofing Consultants LLC was recently contacted by a member of an HOA in Ventura County where that member had learned that his association’s Board of Directors were considering passing a special assessment in the range of 2 million dollars for repairs to balconies and stairs.

Information we got from the owner was that a large nationwide HOA reconstruction firm told the HOA that they had 13 emergency repairs and 300+ non emergency repairs to do and the budget was apx 2 million dollars for this work.

The resident also learned that this nationwide HOA reconstruction firm had waived the $41,000+/- Stage 1 inspection fee provided they were given the repair work. We believe that to be highly unethical and so does that owner. We provided a letter of opinion that the association could self finance the non emergency repairs over a period of several years, taking on a couple buildings at a time to make repairs.

We’re also seeing  companies now advertising “free inspections” and “20% off” specials. With all of these offers, there is always fine print, and fine print never benefits the consumer. If you’re going to buy into these offers, make sure your legal counsel is protecting your interests by reviewing their contract before you sign.

One thing these companies have in common is that they are larger firms with a lot of overhead and with the slowdown of inspection requests coming in they need to churn business. Due to the other services that we offer, we are staying busy with work that they don’t offer such as construction monitoring and building envelope inspections.

At William Leys Waterproofing Consultants LLC, we provide upfront honest bids on SB326 inspections. We strictly follow SB 326 requirements by guaranteeing that an engineer is physically present at the inspection and inspecting the structural elements. We have competitive prices that are straightforward without fine print in our contract. We have a waterproofing expert who writes the waterproofing report which is then appended to the engineers sealed and signed report.

Our strict ethical standards demand that we only inspect and report for the benefit of our clients, not ourselves. We believe that inspectors should not be bidding on repairs.

In Somber Remembrance of The Tenth Anniversary of the Berkeley Balcony Tragedy

A chilling tragedy at Library Gardens in Berkeley occurred ten years ago today, June 16th, 2015 when a deck collapsed with thirteen people on it, killing seven people and leaving six people permanently injured. This is why we inspect.

Take a moment to remember the victims of Berkeley who lost their lives that terrible night on June 16th 2015 – Ashley Donohoe, Olivia Burke, Eoghan Culligan, Niccolai “Nick” Schuster, Lorcán Miller, Eimear Walsh and Aoife Beary and the survivors, who remain permanently injured, Clodagh Cogley, Seán Fahey, Conor Flynn, Jack Halpin, Niall Murray and Hannah Waters.

This should never have happened, yet it did. Poor construction practices and in my opinion outright negligence caused this accident..

In somber remembrance of the victims of the Berkeley balcony tragedy, we want to remind everyone that this is accident is why we inspect. This can never happen again, this is why SB326 and SB721 are now in effect. As professional inspectors, we take our duty to save lives and property very seriously.

Please get your decks inspected, the life you save could be your own.

How A Building Envelope Consultant Can Add Value to Your Residential Building Project

Long term leaks into this building has destroyed the framing behind the siding and because it is so rotted, the siding doesn’t have anything left to be attached.

As building envelope consultants we are often hired to determine where why and how a roof, siding or windows are leaking. After doing destructive testing and finding what caused the problem, it’s often an installer error that created the problem. Yes sometimes it’s defective waterproofing products, but that’s the exception, not the rule.

For architects and their home building clients, one way to ensure that the building envelope is going to perform correctly for it’s expected life span is to hire a waterproofing consultant to review the architects building envelope details, and to perform quality assurance inspections while the building is being dried in. Drying in a building entails roofs, below grade waterproofing, building paper over the plywood covered walls, window and door flashing for example. All of these need to be installed in a sequence to work together for the building to remain leak free.

Whether you are building tract homes, commercial/residential, condos or a spec home, a small add to the project budget to include a waterproofing consultant to assist in keeping your project leak free is a good investment. Consider the costs when a building does leak; there’s investigative costs, loss of use, possible mold claims, expensive repairs and everyone is aggravated.

William Leys Waterproofing Consultants LLC is here to help you with making your building project a success. Reach out today for a discussion on how we can help bring value to your project.

May Is Deck Safety Month, Get Your Deck Inspected for Only $200, Regularly $350

Thousands of Decks Are Over 20 Years Old & May Be Unsafe Take Advantage of Our May is Deck Safety Month Inspection Price of $200, a Savings of $150 off the Regular Price

ARROYO GRANDE, Calif. April 27, 2025 PRLog — William Leys Waterproofing Consultants LLC is San Luis Obispo County’s premier deck inspection company. Having inspected thousands of decks over the last 20 years for Homeowner Associations, apartments and homeowners, we know that decks can be a second living area during the spring summer and fall. We want people to enjoy their decks and know that their deck is safe to use all year round.

With the average age of decks approaching 20-25 years, the risk of collapse or failure increases dramatically as they age. The North American Deck & Railing Association (NADRA) says between 2000 & 2008, at least 30 people lost their lives as a direct result of a deck collapses, and more than 75% of people on a deck when it collapses are seriously injured. The Berkeley balcony collapse in 2015 killed 7 people and left 6 others with lifelong injuries after a deck fell off a building, sending the victims 40 feet to the sidewalk below.

Decks can and do present hazards to people who use them; old decks can have rotted wood, rickety railings and rusting fasteners that can fail when the deck is loaded with people. Bill Leys, President of William Leys Waterproofing Consultants LLC says that deck collapses are not uncommon, and happen frequently when the deck is loaded with people, especially when there’s a party or special occasion and crowds gather on the deck.

For the month of May, William Leys Waterproofing Consultants LLC is offering homeowners of single family homes a special low price to inspect their deck for only $200, a discount of $150 off the regular price of $350 to inspect the deck attached to the home. William Leys Waterproofing Consultants LLC checks and inspects over 25 various parts and pieces of a deck during a typical inspection.

“Saving one person from death or serious injury is well worth the regular price of $350, and at a low fee of

$200, we are making deck inspections affordable for everyone.” says Leys. The deck inspection fee is valid for homeowners and tenants of single family homes only, and excludes inspections for real estate transactions, inspections under SB 721 and SB 326 for apartments and condo’s. This inspection special is good for the entire month of May during NADRA’s annual Deck Safety Month.
