President Bill Leys of William Leys Waterproofing Consultants LLC recently attended a webinar presented by SGH on “Steep Slope Roofs in the WUI”.
The one hour AIA approved course discussed the additional requirements for roofs on homes and buildings in California’s Wildland Urban Interface (WUI) that increase a roofs resistance to ember storms which are one of the biggest causes of wildfires running unchecked through homes in vulnerable areas.
With this new knowledge and increased awareness of the challenges that homes face in the WUI, William Leys Waterproofing Consultants LLC is better prepared to assist our clients as their building envelope consultant.
Staying up to date on new requirements, products and technologies in construction is important and we are dedicated to increasing our knowledge so our clients can benefit.

Recently one of our clients who we have a proposal out with to perform their deck inspections under SB326 reached out with some follow-up questions. They wanted to know if we were going to use a boroscope camera and if we were “certified deck inspectors”. Our answer is no, we are not “certified”. Allow me to explain.
A quick search on Google showed us that there are several companies that advertise they are “certified deck inspectors”. Diving deeper, it seems all these unscrupulous inspection companies claiming they are certified inspectors are directly affiliated or owned by contractors. By claiming they are “certified inspectors” they seek to elevate their bonafides by saying they’re something that doesn’t exist in the SB326/SB721 inspection field. Continuing our search, the legitimate companies that we compete with make no such claim that they are certified. They make statements that they are architects or engineers, which is readily confirmed via the Board of Engineers and Board of Architects.
There are two non-profit national organizations that have deck inspection training courses and they then issue a certificate after the course is completed saying in essence that the person has successfully completed a training seminar. Inter-NACHI (International Association of Certified Home Inspectors) and NADRA (North America Deck & Railing Association) offer extensive courses for inspectors to take online. One other entity online purports to train people to be “certified” SB721/SB326 inspectors specifically related to California. None of these entities mentioned above can make an individual qualified to perform inspections under SB326 or SB721.
We explained to the client that the qualifications to do balcony inspections under SB326 is quite clear; an engineer (licensed as a civil, PE, or structural engineer) or a licensed architect are the only individuals qualified to do the inspection. We explained to our client that the companies advertising that they are “certified deck inspectors” are exaggerating at best and committing fraud ( in our opinion) at worst.
We further explained that these companies claiming to be “certified” only hold contractor’s licenses and that review of their personal and corporate held CSLB licenses showed that they have complaint disclosures against them by the contractor’s state license board.
Naughty boys in the inspection industry include: One unscrupulous contractor has a long list of lawsuits (over 100!) against his company by unsatisfied clients, complaint disclosure on his license for multiple violations of contracting laws, including taking a deposit over $1,000, while another “inspector” has a complaint disclosure showing they hired non-licensed sub-contractors and failed to complete the job for the contract price, while yet another inspector/contractor was forced to disassociate from a licensed contractor for conspiring to defraud the CSLB!
Our client appreciated the information and has hired us to do their SB326 inspection for them as they didn’t appreciate one particular braggart puffing themselves up while denigrating William Leys Waterproofing Consultants LLC.
Our client also appreciated our written guarantee that a structural engineer will personally perform the inspection, that we have no conflicts of interest and that we are humble and no-spin (their words) when it comes to approaching our solemn duty in performing inspections.
Reach out today for a conversation on how we can help you with our expertise, professionalism and integrity for your SB326 inspection needs. No nonsense, no inflated claims, just honest ethical practices to serve our industry and save lives.

The other home inspector missed this “little” issue
A recent inspection we performed for a prospective buyer of a condominium in San Luis Obispo demonstrates perfectly, why you as a buyer need to have your own inspections done at your own cost. This particular inspection found many issues that were glossed over as simply needing patching and painting rather than complete replacement of major components such as windows, doors, decks and subflooring under a shower.
The seller had a pre sale inspection done at their expense and provided that report to the prospective buyer. He had questions and doubts about the report and reached out to us after searching for a waterproofing and building consultant.
Our inspection found that many items the other inspector glossed over in his report as needing “patching and painting” or minor repairs were far from the real situation which was that all the doors and windows were past their useable lifespan and needed to be completely replaced. We found dry-rotted framing on decks, open and exposed framing on columns, dry-rot in the substrate below a shower floor which requires the substrate to be replaced due to fungus infestations.
Major issues that will require tens of thousands of dollars in repairs are now known issues that will need to be disclosed by the seller if the client who hired us doesn’t complete the purchase. This example illustrates perfectly why inspections don’t cost money, they save you money.
If the prospective buyer does move ahead with the purchase they can negotiate concessions, a lower price or credits to account for the costs necessary to fix the problems we found.
Take a look at the photos below to see what we found, and then give us a call at 805-801-2380 to get a quote on your building envelope inspection on the home or building you are considering purchasing.
When you hire William Leys Waterproofing Consultants LLC, you are hiring an ethical, experienced company who puts our clients interests ahead of our own.
Even before William Leys Waterproofing Consultants LLC was formed, President Bill Leys has been assisting clients throughout California recover financial damages from contractors who caused construction defects that led to water intrusion and property damage. As an expert waterproofing consultant serving San Luis Obispo, Santa Barbara, Ventura, Kern and Los Angeles counties, we’ve helped clients recoup hundreds of thousands of dollars in the past few years.
Our expertise in building technology and waterproofing methods, investigative skills and ability to document and report on the problems, the causes and suggested repairs needed have allowed our clients to convince the Contractors State License Board, the contractors at fault and their Bond companies to act. We’ve seen great success with the CSLB investigating complaints, contractors agreeing to repair defective work and have bond and insurance carriers pay on claims made by our clients.
Some recent success stories include helping a client in San Bernardino recover 5k+ in damages caused by faulty deck waterproofing work by a contractor from Palm Springs. Our investigation found that the contractors “expert witness” actually had business ventures with his client, leading to the Judge concluding the contractors witness had implicit bias in favor of his client. In other words, his testimony was rejected by the Court. Our client got a court order that the contractor had to remove a lien on their home and could not collect $5,000 they claimed our client owed.
No blocking between the old and new plywood is a defect that will cause any waterproofing to eventually fail.
Another success story found us assisting a client in Avila Beach whose recent kitchen addition was apparently leaking. Our investigation found windows were leaking from faulty installation, deck flashing that leaked from faulty installation and as a result of our testing and report, the client was able to successfully initiate a claim against the contractors general liability insurance and recover funds to repair their damages. The client made a confidential settlement with the insurance company for well over 6 figures.

One of our greatest success stories is helping a senior couple in Morro Bay CA when their deck project went south on them. We did preliminary investigative work, finding that the waterproofing product a local Grover Beach construction company who calls themselves “San Luis Obispo’s Expert Deck Contractors” was improperly applied. The client, using our report, filed a claim with the CSLB and after the CSLB investigated, was able to recover over $30,000 in financial damages.
Destructive Testing Reveals That the Waterproofing Materials Specified Were Not Installed to the Minimum Specified Thickness
We were able to help a local non profit recover for damages caused by the improper installation of a low slope roof system last year; the entity was concerned after the roof was replaced and there were still leaks occurring. Our inspection and report found numerous defects in the installation of the single ply roof and with that in hand, our client was able to convince their contractor to repair and replace defective portions of the roof.

If your building is suffering from water intrusion, if you suspect your home has defects, if your not getting a response from your contractor and keep getting brushed off, don’t delay any longer. Put the experts at William Leys Waterproofing Consultants LLC to work for you.
We can perform visual inspections, destructive testing (up to $1,000 in value) document the results, write reports that are easy to read, explain the problems and why we believe the defects are caused by a contractor or from defective materials and help you recover damages. Don’t let contractors ghost you, gaslight you or try and evade responsibility. Cslb laws are strict regarding time frames for when you can attempt to recover for damages. The sooner you act, the less damage will occur and the sooner you can start recovering.

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.

Fiduciary duty is defined by Merriam-Webster dictionary as a “duty obligating a fiduciary as an agent or trustee to act with loyalty and honesty in a manner consistent with the best interest of the beneficiary of the fiduciary relationship as a principal or trust beneficiary.”
CAI’ magazine “Common Ground” has a very good article in their March April issue on fiduciary duty. Quoting from the article Bob diamond senior council at Reed Smith in McLean Virginia says”the essence of fiduciary duty is to act in the best interests of those who you serve. A director must put aside personal considerations when making decisions on behalf of the owners.”

When it comes to sb326 and fiduciary duty the duty of the board is to carry out the inspections as required by law regardless of cost or that they don’t have money in the associations accounts to pay for it. A lack of knowledge or understanding about sb326 will not be a legal defense or at least won’t be a strong defense to not carrying out an inspection of the common area Exterior Elevated Elements.
A director for a homeowners association must act within the scope of their given authority, acting good faith use ordinary care Act in the best interest of the association and act reasonably when making business decisions.
The reason sb326 exists is because of the tragic collapse of a balcony in Berkeley that resulted in the deaths of seven people and leaving six with lifelong injuries. Warning signs were evident and the property management company failed to investigate the reported deck problem thoroughly. That is one of the reasons that a multi-million dollar settlement was made before the case went to trial.

We will be performing quality assurance inspections on this project in the East Bay.
We’re excited to announce that we were awarded the contract to perform quality assurance inspections for a large HOA reconstruction project in the East Bay area of San Francisco. The 100+ units in the HOA are leaking at the decks and resulted in damage to the exterior walls.
We will be performing periodic inspections of the weather resistant barriers (WRB’s) the installation of sliding doors and the waterproofing of the decks to ensure that they are being installed in accordance with the plans and specifications. This helps the Association ensure its money is being spent well on quality work and the materials are installed correctly that will last for their expected life spend and perform as intended.
Observing installation of new WRBs integrated into the existing WRBs. A sliding door with the screw coming through the threshold. Building paper installed before weep screed…? It shouldn’t be.
If your HOA is about to undertake a major renovation project, talk to us about how we can help protect your interests by providing quality assurance inspections that will help spot problems before they get away. We report directly to the association and provide a daily report for every visit along with extensive photo documentation. Catching a problem before it’s covered over will save a lot of heartache and finger pointing later on. We find that contractors like having quality assurance inspectors on site because they know that we are there to help the project through to a successful completion.
Reach out today for a conversation on why your association should have a quality assurance inspector on your six-figure + project.
Is humor the best way to market our SB326 inspection services? Viral memes seem to resonate with people these days so it’s worth a shot.
If you need a SB326 inspection you need to vet your inspector thoroughly. Are they independent and free of conflicts of interest? Any inspection company that owns a waterproofing or contracting company is not free of conflicts of interest.
We’ve seen multiple clients coming to us with SB326 reports in hand that were written by contractors, signed off on by an engineer who didn’t actually inspect the EEEs and the report is written to favor the contractor who now uses that report to extort HOAs reserve funds.
At William Leys Waterproofing Consultants LLC we guarantee in writing that we have no conflicts of interest. We don’t own a waterproofing or contracting company, we hire a structural engineer who writes the report and we write a supplemental waterproofing report that is appended to the engineers report.
Call today, time is running out for getting your inspection done before the deadline. 805-801-2380 ask for Bill.
