We’re the Central Coast’s Solution for Building Envelope Compliance Testing!

William Leys Waterproofing Consultants LLC is proud to announce that we have become members of the North American Building Compliance Testing Association (NABCTA) !

We’re constantly seeking to improve our skills, increase our knowledge and bring the Central Coast of California local expertise and professionalism.

If you need building envelope leak testing, litigation support on waterproofing defect claims or building envelope consulting, please reach out today! We provide ASTM E 1105 testing and full compliance reporting.

After a cyclic test, this recently repaired stucco wall was found to be leaking.
Another wall, another test proves that the stucco wall was improperly reassembled resulting in water intrusion into the building.
A spray rack is set up to test the walls and windows on a recently built medical building in Templeton CA

What is E 1105 you ask?

How the Testing Works

Water Spray: A calibrated outdoor spray rack applies water uniformly at a rate of 5.0 gallons per hour per square foot.Air Pressure: An interior or exterior chamber creates a controlled air-pressure difference to simulate wind pushing rain against the building.Observation: Inspectors watch the interior side of the test specimen to see if any water penetrates past the building envelope.

Testing Procedures

Procedure A (Uniform Static Pressure): Applies a steady, constant air pressure difference, usually for a 15-minute test period.

Procedure B (Cyclic Static Pressure): Cycles the air pressure on and off (e.g., 5 minutes on, 1 minute off) for multiple cycles to mimic gusting wind.

Why It Is Used

Quality Assurance: Verifies that field installation, flashing, and sealants were done correctly right after construction.

Forensic Investigation: Helps locate the source of active water leaks in existing buildings.

Quality assurance inspections can also help ensure that the building envelope is being installed correctly. We offer QA inspections for building owners during construction. Catch problems before the building is closed in.

If you are building new construction, get your windows and doors tested before closing in the building. Call today 805-801-2380

Transparency Matters: How We’ve Clarified Our SB 326 Inspection Process

Our Updated Logo Reflects Our Role Coordinating SB 326 Inspections

At William Leys Waterproofing Consultants LLC, we believe that an HOA board should understand exactly who it is hiring, what services each professional will provide, and who is responsible for the engineering judgments required as part of an SB 326 inspection.

Recently, correspondence from the California Board for Professional Engineers, Land Surveyors, and Geologists (BPELSG) gave us an opportunity to take a closer look at how we described our SB 326 services on our website and in our proposals.

We took that opportunity seriously.

The result is a clearer and more transparent description of our role, the role of the licensed structural engineering firm performing the engineering services, and how the different parts of an SB 326 project are coordinated for our clients.

Why We Made Changes



SB 326 projects can involve several different disciplines.

There is an important distinction between waterproofing and building-envelope consulting, project coordination, and the professional engineering services that California law reserves for appropriately licensed professionals.

Although we understood those distinctions in practice, the Board’s correspondence caused us to examine whether they were communicated clearly enough in our marketing and contractual documents.

We concluded that we could do better.

Rather than simply changing a few words, we reviewed our website and proposal language with the goal of making the relationship easier for an HOA board, community manager, or building owner to understand before retaining us.

Clearly Identifying Who Performs the Engineering Work

One of the most important changes is greater clarity about the licensed engineering firm’s role.

William Leys Waterproofing Consultants LLC is a waterproofing consulting and project-coordination company. We do not represent ourselves as a licensed engineering firm.

When professional engineering services are required for an SB 326 project, those services are performed by the licensed engineering firm identified for the project.

That distinction is now stated more clearly in our materials.

The engineer is responsible for the engineering observations, professional opinions, determinations, and engineering report within the engineer’s scope of services. The engineering report is prepared and signed or sealed as required by the licensed professional responsible for that work.

Our role is separately described so clients can understand the services William Leys Waterproofing Consultants provides.

What William Leys Waterproofing Consultants Brings to the Project

Our expertise is rooted in waterproofing.

We have been inspecting decks and evaluating waterproofing conditions since 2007. That field experience gives us a practical understanding of how exterior elevated elements are constructed, how waterproofing systems deteriorate, where water commonly enters assemblies, and how seemingly minor waterproofing defects can contribute to much larger problems.

On an SB 326 project, our work may include project coordination, documentation, communication with the client and engineering firm, waterproofing-related observations and consulting, and coordination of other services within our agreed scope.

But experience with waterproofing does not turn a waterproofing consultant into an engineer.

We believe clients deserve to understand that distinction.

Transparency Should Start Before the Contract Is Signed

An HOA board should not have to decipher a website or proposal to figure out who will actually perform the professional services being offered.

Our revised approach is intended to answer those questions upfront.

Before retaining us, a prospective client should be able to understand:

– who the client is contracting with;
– what William Leys Waterproofing Consultants LLC is responsible for;
– which services will be performed by a licensed engineering firm;
– who is responsible for professional engineering judgments and the engineering report;
– what services are included in the proposed scope; and
– what additional investigation or services may be recommended if conditions discovered during the project warrant them.

We believe this level of clarity is good for everyone involved.

Taking Regulatory Guidance Seriously

Businesses sometimes view questions from a regulatory agency as something to fight or minimize.

We chose a different approach.

The Board’s correspondence gave us a reason to review how we communicated our services and ask a straightforward question:

Could an HOA board reading our website or proposal misunderstand who is performing the engineering services?

Where we believed the answer could possibly be yes, we changed the language.

That process has resulted in materials that we believe more accurately describe the respective roles of William Leys Waterproofing Consultants and the licensed engineering professionals involved in an SB 326 project.

Experience and Professional Licensure Are Different Things

California’s SB 326 inspection requirements exist for an important reason: exterior elevated elements can present serious safety concerns when deterioration is allowed to progress unnoticed.

A successful inspection program therefore benefits from both professional engineering judgment and practical knowledge of waterproofing systems and the conditions that cause them to fail.

Those are complementary areas of expertise, but they are not interchangeable.

Our goal is not to blur that distinction. It is to make it clear.

A Better Process for Our Clients

We believe the changes prompted by the Board’s correspondence have made our company better.

Our website is clearer. Our proposals are clearer. The responsibilities of the participants are better defined. And prospective clients receive more information about the structure of the engagement before deciding whether to hire us.

For an HOA board making decisions involving building safety, association funds, and long-term maintenance obligations, transparency shouldn’t be an afterthought.

It should be part of the inspection process from the beginning.

Balcony Collapse in Hawaii Injures Seven People!

We’re still trying to get more information, a balcony collapsed in Hawaii with 7 people on it. The balcony appears to have only been nailed to the building from what we can see.

As seen here, the deck appears to have fallen off the building. It appears to have been nailed into the building instead of bolted. An inspection probably would have caught that flaw.
Photo used under the fair use doctrine for education.

This is why inspections matter! The 11th anniversary of Berkeley was two days ago, and here we are again, another collapse. For the people on this balcony, they were injured but they will all be going home from reports I’ve read.

Please schedule your inspection ASAP, if you are renting property either through Airbnb or long-term, protect yourself and your tenants with an inspection.

We serve San Luis Obispo County as well as Santa Barbara and Ventura County for deck inspections under SB326 and general inspections for rental and personal property.

SB326’s Forgotten Requirement for Newer Condominiums

Condominiums with EEEs and are turning 6 years old will need to do inspections.

In all of the rush to get older condominiums in compliance with SB 326, what’s been forgotten is the section in SB 326 that requires condominiums that are turning 6 years old to do an inspection.

Watch our video  here-

Closed caption for your convenience

That’s right, when your condominium turns 6 years old from the date of issuance of the certificate of occupancy, the board of directors will need to commission a SB326 inspection. We’ve found that many management companies aren’t paying attention to this requirement or don’t know about it.

Deck Expert Bill Leys Discusses SB 410 & How It Effects HOAs & Deck Inspection Firms Reports

Notably for HOAs and balcony inspection companies SB 410 will take effect on January 1st and impose certain requirements on HOAs and on balcony inspection companies.

For HOA Boards of Directors, you are affected in several ways; the first being that SB326 reports are now considered to be HOA records, which means an owner can request and review them at any time. Secondly, reports cannot be withheld or redacted and third sellers of a common interest development property now must provide buyers with the most recent SB326 inspection report.

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.

Poor workmanship doomed this new addition with intrusion, resulting in tens of thousands of dollars worth of damage to restore the waterproofing. 

Stage 2 Destructive Testing Balcony Reveals Significant Deterioration

As a waterproofing expert coordinating #SB326 inspections on condos in California, I often hear the complaints about costs of these inspections. Stage 1 visual inspections are costly, and if the Structural Engineer determines that further Stage 2 destructive testing is necessary, it can get very expensive very quickly.

However, Stage 2 inspections are very important. When I’m doing my observations of the waterproofing elements, I often find signs of water intrusion into the framing. My engineer and I confer and I explain what I’m seeing, what I think is the cause and they generally agree that a Stage 2 inspection ( destructive testing inspection) is necessary.

Recently we coordinated Stage 1 inspections of a condo building near Cal Poly in San Luis Obispo. We determined that there was evidence of water intrusion into the framing post the waterproofing systems and the independent structural engineer called for a Stage 2 inspection. Coordinating with a team from Whitestone Construction,  Whitestone removed stucco and masonite siding on 5 decks that are on the 3rd floor of the building. These decks are covered with 1″+ of concrete on them, and after the crew from Whitestone removed stucco and masonite siding, we discovered significant structural damage that was so alarming we forwarded the photos to the engineer who immediately ordered the decks off limits to use.

The concrete decking and stucco siding hid serious damage that presented immediate life safety concerns to us. This meant the decks were unsafe to be occupied until repairs are made.

While looking at the damage, the Berkeley balcony tragedy came to mind. Here, as in Berkeley, students used the decks to hang out on, perhaps leaning on the railings to talk to friends below. A person in these balconies could have fallen from a railing giving way because the framing it was secured to was so rotted out wouldn’t hold.

The horrors of Berkeley can never happen again. Thirteen students in Berkeley fell 40′ to a concrete sidewalk. Seven died and six are left with serious life long debilitating injuries and the mental pain of that terrible evening.

Berkeley is why we coordinate balcony inspections, and Berkeley is why I have become a warrior in the battle against bad contractors doing bad work that gets people killed. SB 326 needs some fine tuning, but overall it is saving lives. My peers in the industry and I stand up for keeping buildings and decks safe.

Independent inspectors, free from conflicts of interest, are your Associations best defense against another Berkeley tragedy from happening again. Yes inspections aren’t cheap, but a lifetime of being haunted by nightmares of people dying in a fall from a balcony and the costs of a lawsuit for negligence will quickly outrun the costs of doing inspections.

Reach out today to get started on having WLWC coordinate your balcony inspections and get your association compliant now. Don’t delay thinking the deadline will be extended ( it might be) and even if it is, dry-rot is working on weakening your decks, putting people’s lives at risk.

Our warning notice to not use the deck until it is fixed
Don’t delay your balcony inspection! The life you save could be your own.

Remembering The Berkeley Balcony Victims on the 8th Anniversary of The Tragedy

Today marks the 8th year since the balcony at Library Gardens literally fell off the building with 13 young adults standing on it to take a birthday photograph Seven people died as a result of a near 40 foot fall to the concrete sidewalk below. Ashley Donohoe, Olivia Burke, Eoghan Culligan, Nick Schuster, Lorcan Miller died at the scene and Aoife Beary passed away on January 2, 2022. The survivors were left with lifetime suffering and pain from grievous injuries.

I contributed to several newspaper articles with my opinion, I reviewed plans, photographs and other information sent to me by journalists for the LA Times and Mercury News Group. There is no doubt in my mind that the defect that caused the deaths and injuries to these kids was set into motion the day a carpenter took a saw to the laminated veneer lumber beams and cut them to provide slope on the deck without then sealing up the open exposed wood/glue to prevent water from getting into the material. With the addition of OSB/oriented strand board, and all of that crap wood being soaked for months during a rainy winter set into motion the demise of that balcony.

The builder didn’t protect the deck from moisture the carpenter didn’t protect it from moisture nobody protected it from moisture and as a result of carelessness neglect whatever they want to call it the blood on that sidewalk may be washed away but it’s still there… That sidewalk is holy ground. I make a sign of the cross when I’m on that sidewalk.

There is no doubt in my mind that a balcony inspection should have found problems and that deck would have been. People had reported that the deck had unusual slope… Which seems to indicate that the deep beams were slowly failing. It is also reported that they were mushrooms on the ceiling below that was simply scraped away, which should have been a huge warning sign of moisture intrusion. It certainly would have set alarm bells off in my head.

The Berkeley deck collapse is on my mind every time I perform a balcony inspection. I think what if that was my daughter or son lying on that sidewalk? I think about the parents and families who lost their child and I renew my vow each time in insisting that I do the best inspection possible, that when our engineer signs your report that your balconies are safe, that I won’t wake up one morning to the news of a deck collapse on a property we’ve inspected. This is that important to me.
