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.

The Stucco Wall Repairs Looked Great, Until We Water Tested Them… And They Failed

  • Stucco Repairs Are Not Easy to Do
  • Lapping New Building Paper Correctly Under Existing Building Paper is Critical To Keeping The Building Dry
  • Hiring an Independent Quality Assurance Inspector Protects Everyone
  • William Leys Waterproofing Consultants LLC Offers Affordable Quality Assurance Inspections

Our last blog post talked about an owner who hired us to perform an inspection on their condo unit at a well known West Hollywood property. The condo had experienced water intrusion while the owner was away and they came home to find water on their bedroom floor.

Remediation began with removal of flooring and drywall where mold was found. The only problem before fixing everything was to find out where the water was coming from. One clue was the fact that recent stucco and deck work had been done. Couple that with the fact that several rain storms had occurred and the answer seemed to point to the wall being the culprit.

The view from the interior of the wall shows an odd repair of the stucco and building paper using spray foam.

We started with a visual inspection of the area, and made some odd discoveries. New building envelope paper was integrated into existing paper using spray foam. Flashing was assembled using sheet metal tapping screws where it overlapped the next piece of flashing. We could see several areas where stucco was visible as it had pushed the paper out, creating a path for water to follow into the building.

Stucco Visible Behind Open Building Paper

Returning the following morning we set up an informal water test. Using a lawn sprinkler we sprayed the wall where the drywall was open on the interior. Within 20 minutes we observed water on the interior of the building, indicating defective repairs to the building paper.

Water can be seen running down the interior of the wall in this photo. We found two other leaks during the test as well.
A lawn sprinkler imitates rain soaking the building.

So now we can clearly see that the repairs are defective in this one limited area. However our question then becomes if this one limited area has three different areas that are leaking, and the contractor has replaced hundreds of lineal feet of stucco, building paper  and flashing, how many other areas might be leaking as well? Given the data we already have, we’d have to guess that there’s more leaks that remain unknown.

Conclusion- despite the optimism that your contractor is making repairs correctly, the realty is somewhere in between. Attention to detail is critical. Even then mistakes can be made. By having a quality assurance inspector observing and checking your contractor’s work, you can expect that the quality of the work will be much higher. That’s because when people know they are being watched and checked they spend more time doing the job right the first time rather than having to redo the work.

Give us a call today to discuss your condo rehab work and we will discuss how QA inspections improve your job by holding the contractor accountable.

Bill Leys has been performing quality assurance inspections all over California for many years and his diligence in inspecting contractors work has helped ensure that hundreds of leak free homes and condos are restored correctly. Call Bill at 805-801-2380 today.

Pesky Leak to Be Investigated By William Leys Waterproofing Consultants LLC’s Leak Investigation Sleuths

Where’s the leak? That’s why we were hired, to find a pesky leak that has evaded detection of its source for several years.

William Leys Waterproofing Consultants LLC has been retained to provide leak investigation services by a large builder of medical buildings in California. The pesky leak has caused several offices in the building to be vacated during the rainy season due to concerns over potential mold hazards, never a good thing for patients visiting the building.

We will be using a spray rack to water test the facade of the building in San Luis Obispo county this week. The facade features store front windows and a stone finish on the 4 year old building. Leaks can often hide in such situations and the building’s owners and its construction team that built the building hired us to assist in the leak investigation due to our history of expertise in leak investigations and building enclosure experience.

If your building is experiencing leaks, reach out to us to have a discussion on how we may be able to assist in determining the source and make recommendations for repairs. Our leak investigation experts are ready to assist! Call today 805-801-2380

While we were inspecting the roof, we found the roof drain sump pit clogged up with debris. We also found that the TPO roof has reverse laps that buck water flowing towards the drain.

“Structural Issues” Cause Bay Area Condo Building to Be Evacuated Until Temporary Shoring is Installed

UPDATE AS OF 3/19/26

We spoke with reporter Kevin Nguyen at the SF Standard regarding this property after he reached out to us asking about this property. We were the source that alerted Kevin to the fact that the picture below by  Anna Nevskaya showed failed post tension cables poking out from the building.

Turns out that post tension cables that support the podium deck slab have failed. I saw a review on Google by an owner at the property and knew instantly this building is F’d.

I’ll now predict that the slab can’t be fixed and the building will have to be demolished. What engineer in their right mind would believe that the other cables that aren’t broken are ok and just recommend repairs to the failed cables? No one in their right mind would in my opinion.

Post tension cables have broken in numerous places in one area as seen in this photo taken by Anna Nevskaya (and republished here for public knowledge.) The cause is unknown but is likely related to either damage caused by a massive fire that occurred during the construction, water damage or both.

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.
